USB ports - half functional??

I'm using MS-7057 Intel 845-GV series.. I have 4 USB ports at the back (onboard); 2 at the front. Whenever i connect anything to the 2 at front, the whole pc reboots after saying "The USB device you connected exceeded power limit on the hub" or sometrhing. But thats ok, i barely use them, no issues.
For my rear USB ports, If i connect a device, it'll light up, indicating that it is indeed receiving eough power.. right?? But Device Manager fails to recognize that anything has been connected. I tried re-installing Windows, Updated BIOS, removed the battery and tried resetting the bios, every possible thing that i knew could possibly help me. However, unsuccessful. What to do??

Okay, first, make a signature. Look at mine to get an idea of what we would like to know.  If you are having problems with USB ports, read this topic.  Also, here is what I've written before concerning USB issues:
Quote from: Frankeputer
Check to see if there is a wire running from your Front USB ports to the #10 slot of your USB block which connects to the motherboard header.
USB connector block layout which corresponds to the pin layout on boards with the Intel spec for USB. Do not cut the pin on the MOBO. You are removing/cutting the wire to the connector block from the case.
2 4 6 8 10(this wire, #10, not needed)     
1 3 5 7 9(filled/key)
If you find a wire leading to the #10 spot on the block, remove that wire. My block has tabs so that you can pull the wire out, or you could snip/cut the wire leading to that position--if you cut the wire, be careful to cut the correct one and cut it in such a way that it may be repaired if you make a mistake.  Make sure you wrap the wire, the exposed end/s, you remove/cut with electrical tape so as not to accidentally cause a short. I actually folded the wire back and wrapped it.
2 posts to read--Here and Here.
This seems to be a common issue involving many different case manufacturers. I don't know how it applies to other MOBO manufacturers, but in these forums it is not limited to a specific MSI model or supported chipset(Intel or AMD).

  • Connecting 5th gen. ipod to new LG stereo with USB port. Functionality?

    Hi,
    I recently got a new LG "micro hi-fi system" (model LFU850) with a USB port for MP3 players. The problem is when I connect the ipod via USB, I lose all the functionality of the ipod database. In other words, the stereo numerically lists about half of the songs on the ipod (293, for example)and plays them in an order I can't figure out. I can't select playlists or albums on the ipod. The ipod does charge and allow the music to be played, and it does sound GOOD. Anything I can do to restore ipod menu functionality while hooked up to the stereo? Thanks in advance! Mike
    5th gen.   Windows XP  

    I had the same problem. Because music files aren't dragged or copied into iPod hard drive (the normal process for most mp3 players) but instead downloaded through iTunes into the iPod you lose functionality because iTunes categories music files in numerous and simultaneous ways e.g playlists/genre/artist/album/ etc. Most usb enabled stereos are not fitted with the technology to unlock all that information.
    There are 3 solutions you could try.
    1. Place music files and folders directly into iPod hard drive and not through iTunes. See if that works. The only problem with this solution (if it does work) is if you still want to use your iPod as a portable music player on it's own you will have to upload your music files again through iTunes into your iPod.
    2. Buy a speaker system made for iPod but what's the point when you already have a usb enable stereo. One of the disadvantages of owning an iPod is that you never stop accessoring, the iPod on it's own is never enough because it lacks many basic utilities.
    3. Stick to your old portable mp3 player or buy one with greater capacity - (there are some with 8GB) and return or sell your iPod (This is the option I chose). I can't offer advice on buying rival mp3 players such as Creative Zen or Zune as I'm not sure of what method they use to download music files.
    Let me know how it goes!

  • B500 USB ports non-functional

    The USB ports on my 18 month old, out of warrenty, Ideacentre B500-57115233 no longer function.  Computer was powered on and hibernating, but would not awaken using wireless (USB, not bluetooth) keyboard and mouse.  Technician at computer repair shop said all ports were dead, could not be repaired, and computer motherboard had to be replaced.  Only way to access system is with a PS2 keyboard (which I do not have).  Have accessed files remotely through network so system otherwise operates normally.
    Any ideas about how to repair USB ports?  If motherboard needs to be replaced, where do I get one?

    code 31 is that the device is not working properly because Windows could not load the drivers required. A fix for that is to update your driver. You could read more about it at the link I posted below, there are also troubleshooting tips as well. 
    http://support.microsoft.com/kb/310123
    Open Device Manager
    In the device's Properties dialog
    box, click the Driver tab,
    and then click Update Driver to
    start the Hardware Update Wizard.
    Follow the instructions to update the driver.
    Note You may be prompted to provide the path of the driver. Windows may have the driver built-in, or may still have
    the driver files installed from the last time that you set up the device. However, sometimes, it will open the New Hardware Wizard which may ask for the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver
    from the hardware vendor's website.

  • RMBP (Early 2013) BOTH Usb ports not functioning.

    Hi Guys.
    I have a Retina Macbook Pro 15" (Early 2013) with 10.10.2 Yosemite.
    My left side USB port stopped working about 4 months ago so I've been relying on a hub and the right side USB port for awhile now. When I went to use my laptop this morning, the USB port wasn't functioning at all. I've plugged other USB devices into it and it's not being recognized at all. The devices work in other computers and there doesn't seem to be any damage to the USB port physically.
    On the USB port that just stopped working, I had a USB 3.0 4 Port hub connected with a WD External HD, and a small USB Audio Interface.
    I've already tried an SMC Reset, PRAM Reset, Repaired Disk and Disk Permissions. None of that worked.
    I bought it about a year ago from a Best Buy and I got their 2 year plan. But before I go there, is there anything else it could be that I can do myself?
    Thanks
    Joe

    Hi. You have done most of the things I would have said to try. In rare cases reinstalling the Operating system can fix the problem. I have one link of suggestions you could try. Other tan that taking it back to best buy seems the only option left.  http://smallbusiness.chron.com/reset-usb-ports-mac-laptops-51619.html

  • USB port not functional at startup

    This is 100% reproducible. I plug my 23" Apple Cinema monitor into my new 2.8GHz MacBook Pro. I use a display to DVI connector for the monitor and plug the USB from the monitor into one of the USB ports on the mac. I have a third party mouse and keyboard plugged into the back of the monitor in the build in USB hub. Each time the mac starts up, the keyboard and mouse are dead. I simply switch usb ports and they come back to life. For some reason they are not recognized at startup. Does this have something to do with the hub on the monitor being "slow usb"?

    Is the hub in the monitor self powered (from the monitor's power supply) or does it get it's power from the MBP port? If it gets it's power from the MBP port, and the inrush current of trying to power up two devices at the same time exceeds 0.5 amps, the MBP will shut down the USB port.

  • USB ports function intermittently

    Same problem as many others but I've not read a satisfactory 'mend'.
    Both my onboard USB ports function when they fancy. I've got a USB pcmcia card that works fine but I also need that slot for a firewire pcmcia card from time to time meaning there's a conflict.
    I've tried resetting the PMU as appropriate for my model - I know the button press happened as I had to reset the time and date. But still no joy - although running techtool delux tells me the usb onboards passed data transfer tests.
    Has anyone managed to mend their onboard USB ports at all?

    Hey, what do you know? Looked at my Apple Hardware test CD and the OS on it was 9.2 so...
    I just rebooted into my old OS 9.2 which is possible on the old Titanium beauty. Funny how quickly a desktop once so familiar becomes. I digress.
    So the onboard USB ports both functioned perfectly. Mouse lighting up and the keypad I use had the green light on. Both working perfectly.
    Then, rebooted back into 10.3.9 without removing the devices and hey presto! Both working under 10.3.9 once more.
    Is there any more literature about 10.3 and the onboard USB ports I wonder???
    Success in the meantime.

  • How can I test the usb port on my Time Capsule to see if it is working?

    Ever since lightening struck nearby (which took out our internet and copy machine) the printer I had connected to the usb port on my Time Capsule in my office has has failed to print through the TC. I can plug the printer directly into my MacBookAir and can print just fine. So there is nothing wrong with the printer nor the usb cable.
    I've turned off and unplugged the printer with the usb cable connected & disconnected to the TC, no change. I've unplugged the TC, no change. I've opened the printer utility several times, and always get the "offline" error. I open the print queue, and it says the printer is not connected. I reinstalled the driver for the printer, still the same thing.
    I'm starting to wonder if the usb port on my Time Capsule got fried. Any help anyone can give in trying to see if the usb port even functions anymore would be greatly appreciated.
    My Time Capsule is model no. A1409.

    Power is not likely to be killed .. it is the data components that are more fragile.
    So you do have power which as you say is why the USB flashes.. but you don't have signal.
    The only other thing you can do is use USB powered hub.. if you have one handy.. but I would not go out and buy one.
    A damaged board is impossible (at cost less than replacement TC) to repair. And repairers do not like working on stuff damaged by lightning as components that did survive were stressed.. the transistor junctions become liable to fail at any time.. so you repair it and it just keeps coming back as not working. Sorry if you cannot use it without USB junk it and buy a replacement. A second hand Gen3 is about the best of them it seems.
    You can also buy an ethernet to USB print server.. but a new ethernet or wireless network printer is probably near to the same price.
    You can hunt ebay for second hand USB print servers.. or airport express, extreme or TC.. often you can find something suitable for just a few dollars if you shop well. Since you don't need the latest greatest to do this sort of job.. and people are disposing of things like USB print servers as soon as they buy network printers.

  • USB ports and Pocket Drive Unrecognized (IQ-775)

    Hi all:
    With no warning, the two front USB ports stopped  functioning (rear ones are OK) and the Pocket Drive is no longer recognized. Worked one day, did not work the next. This happened simultaneously, so I assume it is related as the Pocket Drive is a USB device.
    There is power to all of these ports, as when I plug something into them, or insert the pocket drive, the power lights come on, but the system does not show them. The pocket drive no longer shows on the folder tree, and if I remove it and connect it to a working USB port, it reports 'unknown device', tries to load a driver and fails. The Windows message says, "if this continues to occur, replace device" Easy for them to say!! I have used the Disk Manager, but it too cannot find the pocket drive anymore. Interestingly, the Pocket Drive works fine on other computers as a portable drive and is recognized as "HP Pocket Drive", so there is noting wrong with the device.
    The pocket drive has disappeared from the Device Manager, and all of the USB ports show are 'working properly', but of course we don't know which are which or even if the front ports are listed as they are not identified
    If anyone knows how to repair this problem or has had similar, I would be grateful. My IQ-775 is out of warranty so the repair is on me. I don't know how USB ports 'fail', but I am sure it is a 'fixable' problem.
    The machine is steadily destroying itself, just sitting on the desktop. The WLAN adapter went first (on both of my HP machines), then the display drivers, then the Lightscribe, now the USB ports. Planned obsolescence at its finest!
    Thanks

    Cooper, it's NOT going to be all the devices that are having problems, the OP's issues are related to the USB hub/ports not working properly. Reinstalling drivers for all the USB devices including the Pocket drive that doesn't use any, would be an exercise in futility.
    OP, try removing the USB root hubs in question in Device manager and letting the OS put them back on a reboot, that has been known to resolve issues like this, you can also go into the BIOS and do a "reset to default" I know that sounds strange, but it can resolve weird USB issues too.

  • Damaged USB Ports - Need solution

    Hello,
    I am having a problem with my Macbook Pro 13-inches Early 2011           OS X Version 10.7.5           Processor 2.3 CHz Intel Core i5          Memory 4 GB 1333 MHz DDR3          Startup Sisk Macintosh HD
    Since about a year I noticed that one of my two USB ports stopped functioning as when Iwould  plug some device through it (i.e. flash memory card, external har disk, or whatever it may be,) there was no reaction on the mac. A few months back the same problem developed with the other USB port. I especially noticed this when iTunes would suddenly appear to not identify my iPhone. However, I noticed that if I press hard on the USB cable head and keep pressing, the computer was able to read the device.
    I do not know what could have been the cuse of this damage. I was told that it was due to my personal usage. I took my macbook to a mac specialist workshop and it was figured that the only solution would be to replace the USB ports with new ones while maintaining the same motherboard. However, I refused to continue when I saw the quotation (300 euros) for the job. It seams too much to pay for a macbook tht's rather a bit old.
    My daily work requires that I tranfer fils back and forth to USB cards for printing, as well as archive and backup files on external hard disks. Any ideas or solutions that could get this type of job done would be highly appreciated.
    Thanks in advance

  • Split x2 problem with USB ports not working

    My computer is somewhat new and this problem has been happening since I first got it.  I couldn't find anything about this problem here or elsewhere online.
    When I plug anything into either USB port (I've tried my phone and an external harddrive) the computer like sort of recognizes it on and off.  When I plug in my phone the computer beeps at random every several seconds and doesn't recognize it.  The external hard drive was sort of recognized but only on and off and I couldn't move things from it to my computer because it wouldn't stay connected long enough.  It's literally like every 2-3 seconds it recognizes the USB thing, changes it's mind and then recognizes it again, etc. forever.
    I haven't had a chance to test the SD card slot or the HDMI port yet.
    Sometimes the mouse freezes also, I'm not sure if this is the same problem (related to connection between the tablet and the keyboard parts) or if these are separate problems.  It seems to be happening less often and goes away if I wait for a moment.  Still annoying but the USB ports not functioning is a more urgent issue.
    I need help, is there a way to fix this or is something faulty with my computer?

  • USB only half working!?

    Hello, I'm having trouble with my USB ports. I recently bought and external HD and when I plug it in the lights turn on and I can hear it spinning but the computer doesn't see I've plugged anything in. Same deal with my USB camera, light turns on but the computer says I have no camera plugged in. It seems to be doing this with my guitar port as well and anything else I plug in!
    I recently had my computer at a genius bar and the tech was able to boot up my computer on his external HD with the firewire port, but since I've updated my software to 10.3.9. I tried reinstalling the software update through the download on macs website and I've reset the PMU with no luck of the computer seeing anything I plug in.
    Am I missing something?
    Thanks in advanced!

    You mentioned at the Genius Bar, the external HD that they connected was FireWire. This is different from USB. So if the FireWire connection works, that doesn't mean that your USB ports should function as well, since they're not directly connected (no pun intended) to each other, even though they're on the "same" place on the logic board.
    See this posting I made on a different thread:

  • The USB port on my 4th generation Airport Extreme does not recognize any peripheral devices whatsoever.  In other words, it does not function at all.  What can I do?

    I have had my Airport Extreme for almost a year now.  I have not been able to get it to work.  It has never worked.  I have tried everything in the apple manuals, my peripheral device manuals, and online help.  My Airport Extreme Base Station has a completely dead USB port.  The USB connector does have voltage and ground.  Apparently there is no data transfer.  I do not know how to test the data pinouts.  I don't know if it is a software or driver problem, or if it is a hardware or wiring problem.  My computer is a mid-2009 13" MacBook Pro.  All of my external devices work well with the MacBook Pro.  The USB functionality on the MacBook Pro has always performed without a glitch.  It seems the problem with the Airport Extreme must either be a network communication problem or a hardware/hardwire problem.  I bought the Airport Extreme to build a home inTRAnet network.  I have a seperate 3rd party router for inTERnet.  Contrary to what the manuals declare, the initial setup of my Airport Extreme requires inTERnet setup during the process.  Even when the choice is made to limit the network access to LAN only, when I reach the end of the setup process, a prompts reads that the Airport Extreme may not function because I have not set it up for inTERnet with the WAN.  Well, Dah...  during the intial stages of the setup I told the machine to configure an inTRAnet only LAN setup.  So...  I went ahead and set it up for inTERnet and WAN.  Either way, the USB port is not working.  Then I set it up for the whole package, WAN, LAN, and everything.  Still... no function out of the USB port.  Any ideas?
    P.S.  The Ethernet works and so does the 802.11 tranceiver.  The USB port is the only problem, but a major, major one for my needs.  There is no peripheral functionality.

    Okay so I figured it out.  I inherited the Configurator already set up so I didn't realize that our former administrator was brilliant and set things up a little differently.  To anyone else who finds themselves in this spot try this:
    After you plug the iPad in and open Configurator instead of trying to 'Prepare' the device click 'Assign'
    There should be groups of Users listed on the left hand side of the screen.
    Select the group you want the ipad to be a part of, or make a new group. ***Note a group can be one person so this is a good feature for teachers to have individual app assignements for students.
    After you select the user group click the little plus ( + ) button on the bottom of the screen under the second column of info where names and device serial numbers should appear.
    Type the name of the person, group, whatever you want to identify that assignment by into the blank that pops up after you hit the plus ( + )
    Then select the assignment you just made and tohe 'Check Our' button at the bottom.  At this point a box will pop up with a window at the top listing all devices supervised by Configurator.  There is a tiny down arrow button that opens a scroll down menu to the right of this box.  Click that, then select the device connected by USB as the one to assign. 
    The name of the assignment you gave it will show on the lock screen now and you can assign apps and profiles to the device like you would any other device in your Configurator inventory. 
    Good Luck.

  • I have a macbook pro4.1 and the sound chip in it failed. My speakers and microphone no longer work. Does anyone know of an external speaker and microphone set that plugs into the USB port so I can continue to use both of these functions?

    I have a macbook pro4.1 and the sound chip in it failed. My speakers and microphone no longer work. Does anyone know of an external speaker and microphone set that plugs into the USB port so I can continue to use both of these functions and not have to pay to have the entire main board replaced. Preferably something under $100.

    I don't think you're likely to find a set of external speakers that come with a microphone and plug directly into a USB port. There are USB audio cards that look like tiny flash drives but have microphone and headphone ports in them, to which you can connect a typical two-plug Windows PC headset with a microphone, or else you can connect external speakers and a stand-alone microphone. Those adapters typically cost under $10. I don't know anything about the quality of sound that can be expected from them.
    I have a Griffin iMic, which is much the same idea but larger, a bit more expensive (retail~$40), and perhaps delivers somewhat better sound quality (I hope so, but I don't know because I've never had occasion to try one of the little ones).

  • Windows 8 USB ports have stopped functioning.

    I have a Envy 1534 desktop and after taking an update to windows 8 today my keyboard and mouse no longer function past the boot system. When windows loads the keyboard goes dark and I cannot use any of the USB ports on my system. This renders the system completely useless. I have tried to go back to an earlier system point however apparently the update was already installing because as soon as i reboot it immediately reinstalls its self before i can stop it. I have not been able to access the safe mode and the refresh function fails because the "drive with my OS on it is Locked". This issue has been solved elsewhere by changing the USB mode in your bios however HP does not allow access to these bios functions. At this point I am at a loss as i cannot access windows at all, and the restore functions seem to be non functional.

    Hi,
    If you run into a "locked HD" situation then you will have to clear the CMOS to get the PC back to the default BIOS setting in case secure boot was enabled.
    Boot up a Windows 7 or 8 installation CD and go to the command console and get MSCONFIG launched.  At that point you should be able to set the boot to safe mode for the C partition on the hard drive.  I just tried this process recently and it worked for me.

  • All USB ports seem to stop working "randomly" but some remain functioning until unplugged and plugged back in. [WINDOWS 8.1]

    The devices that die right away are the network adapter and any USB memory stick plugged in, they still have their lights and all running but aren't recognized in "This PC" and the network adapter isn't found in "Control Panel\Network and
    Internet\Network Connections".
    My keyboard, wireless mouse that runs through the keyboard's USB ports and the external HDD remains functional UNTIL I pull the plug on them, after that plugging them back in does nothing.
    I put randomly in quotations because it seems to fail more often when I download something at speeds over 3Mb/s, for an example downloading Hearthstone through the Battle.Net client will more often than not make the issue happen after a little bit. BUT it still
    happens randomly during NO network load what-so-ever.

    * Set the Power Options to high performance and disabled "USB Selective Suspended Setting"
    I simply don't know what to do anymore and it's breaking me down, I need this fixed before the weekend or the LAN I'm planning to go to will be a disaster and I'll probably go insane trying to solve this myself. 
    Just tell me whatever more information you could need and I'll supply it, I'm desperate to get this solved.
    **I never had any of these issues on my old PC that had different parts but the same network adapter and external HDD so they are not to blame for this, same for keyboard and mouse.**

    Hey, I hope this helps you out a bit... I have had the same issue on my Asus K55A notebook with Win8.1 Pro x64 from the beginning! Thru my extensive research I found something interesting and the possible cause to all this! What I found was that by design
    the xHCI Host Controller has virtual HS 2.0 Ports linked to the 3.0 Ports... Enabling compatibility with 2.0 devices ok... What happens is that the xHCI stack is unstable just like you say... The ONLY WAY I was able to fix the problem was by unlocking the
    UEFI/BIOS to allow me full access to USB Configurations... I had to disable 2 of the HS ports under the xHCI Controller since I have only 2x 3.0 ports... This allowed 3.0 devices to be enumerated correctly under the xHCI stack and 2.0 devices now were enumerated
    under the EHCI 2.0 stack... That's what worked in my case... I'm still digging around for more info about this issue because I find it so odd that no one discovered this when designing xHCI stacks and drivers at MS for Win8/8.1 x64... I hope I shed some light
    on this issue... Good luck and keep us posted!
    Hi, Sebastian. I have the same problem but i'm getting crazy trying to solve it. Can you help me to unlock the UEFI to access full USB config? and give me some suggestions on how to solve the problem?
