945P internal USB port problem

Power exceeded on USB Port 945P motherboard - NO DEVICES CONNECTED
Part Number: MSI 945P Platinum Socket 775
CPU: Intel Pentium 4 640, 3.2 GHz
Memory: Corsair 512MBx2 PC4300 DDR2 533MHz
Operating System: XP Pro
On the motherboard, I have added more external USB port (case mounted), these ports are connected to the mobo on the connector JUSB2.
Now, Windows gives an error stating that the power has been exceeded and must reset or close the port.
There is no device connected to these USB ports, only the wires that lead from JUSB2 connector to the case mounted USB ports.
Did any of you had the same problem?? Thanks.

Have you checked to see if the USB, that is mounted to the Front of the case has any Shorts?
You might also want to remove the USB that is plugged into the Header on the MOBO.
One more thing you might have hooked up the USB header wrong.

  • Apple USB keyboard does not work with one internal usb port

    Hi everyone,
    hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
    Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
    After searching the web on such problem, I tries a few things such as:
    I tried the keyboard on another computer (windows): works fine
    I tried usb stick and external DVD reading on the left internal usb ports: works fine
    I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
    I tried the SMC and PRAM reset : nothing
    Any idea ??

    I'm facing the same problem, found any solutions ?

  • Internal usb port?

    I am looking for an internal usb port on the MAC pro motherboard. seems the Express 34/54 card requires a usb connection in addition to placing the card in one of the PCIe slots. The card manufacturer refers to the USB internal connection as an internal header. Not sure what this means but it would be nice to have an Express 34 PCIe card in the machine---using it with the new Sony SXS video cards.
    any idea if the MB has one of these connections?

    thanks for the info. as I explained, I was trying to install an Express 34/54 reader card into one of the PCIe slots on a Mac Intel. There are cards out there, but they come with an additional usb cable that you must connect from the card (mini-usb connector) to the mother board (a female 5-pin connector--single row).
    another solution is to buy the external sony device for $220. (Express 34/54 to USB2) which is an external housing enclosing the same card with a supplied AC adapter. This format will be a major format in the future for shooting video, so I hope someone develops a cheaper solution.
    thanks for the help

  • Using a PCI card INTERNAL USB port

    Hello to anyone reading this !
    I've just installed a PCI card in my G5 in order to add more USB ports. When I started searching for one, i was surprised to see most had an internal port, I couldn't really see the use of that. A friend told me it can be used on PCs to plug an extension towards a free port in front of the main unit.
    Considering i can't do this on my G5, I was wondering how to take advantage of this internal port and I'd like to know if I can plug my USB Bluetooth adapter, as it doens't need to be visible and it would free one of my external ports. The question is, are there some security restrictions regarding what you put INSIDE the unit? Isn't it too hot inside to leave the bluetooth key or anything else that is not designed to be inside?
    Does anyone have any advice?
    Thanks in advance

    With all the airflow in a G5, I don't think heat will be a problem, but a Bluetooth unit probably will not be useful inside a shielded metal case. The Apple Bluetooth card connects to an antenna wire that goes outside the shielded section, but I don't think there is any way to connect that wire to the USB Bluetooth module.

  • Mac Pro 2008 USB port problems - persistent

    Hello all,
    I have a 2008 Mac Pro - standard config : 2.8Ghz 2Go Ram ATI 2600.
    At the outset I did a clean install onto a 1To Seagate drive.
    From day 1, and before adding any third party applications, the aluminium keyboard would suddenly stop working. If I changed this for my old G5 plastic keyboard, I had no problem. The aluminium keyboard would work again sometimes if I changed USB port, sometimes only after rebooting.
    This problem occurred randomly, a few, or many times a day.
    Apple, after going thru' a number of tests with me over the phone, finally sent me a new keyboard (after having sent 2 white plastic models). This changed nothing. I then had a problem with the white plastic keyboard and one day, with a USB drive linked to a USB port I got the error message of having disconnected the disk without having ejected it first. That told me that the problem was not with the keyboard but with the USB ports (power to them?).
    I did a clean install (with erase disk 1 pass) under 10.1.5 - the problem didn't go.
    I then did a clean install again 10.1.5 followed immediately by upgrade 10.5.2 and the graphics upgrade. I installed no third party apps for 2 days. I had no problems. I installed some apps. No problems for 3 days. I ran all this time on a plastic keyboard. Today I plugged in the aluminium keyboard. No problems for 8 hours and suddenly tonight everythings starts over again.
    I've had to do 4 reboots in the last hour. I'm back on the plastic keyboard. But if I lose that like last time I'm pretty convinced that this is a hardware issue.
    Curiously I have not seen this problem cited in any forums on the Apple boards and other Mac
    Any ideas ?
    I wan't this machine changed. It's my work tool and I can't afford to lose so much time…nor to get so frustrated.
    Apple, Help ! Please !
    P.S. My first Mac was a MAC SE !!

    I think there is a problem with the usb ports on the MacPro which I also think is causing some of the bluetooth problems that are being reported around. Here's why.
    I have a "base" new MacPro (2xQuad 2.8, 320G drive, etc.). After getting the unit going with the standard usb keyboard and mouse I then paired my Apple wireless keyboard and mighty mouse. All worked fine. Then the problems started. I have security set that requires a log in when booting, however after restarting, or rebooting, the MacPro the wireless keyboard and mouse were no longer recognized and I was stuck at the login screen. If I then connected my original Mac usb keyboard it would not work. The ONLY way I can get the usb keyboard to work is by having it connected when I reboot/restart. Calling Apple support was...well let's just say less than useless. So I have been doing a lot of experimenting on my own. I have finally found out that if I have nothing at all connected to any of the usb ports then the MacPro will recognize my wireless keyboard and mouse (although it does take some time to recognize it). If I connect my usb devices again and reboot...back to the same situation. No connection to my bluetooth devices and my usb keyboard will not work (unless I again reboot with it already attached). Now before you say it's my other usb devices let me tell you what I have....just a Canon printer and a Western Digital USB drive that I use for Time Machine. Both of these units have been working fine for over a year and work absolutely fine when connected to my Mac Book Pro.
    I believe the bluetooth device inside is connected to the usb bus internally which is why I think the usb bus is the "root" of the problem. When certain usb devices (and heck it my be almost any usb device) are attached then the usb internal hardware screws up, which kills the bluetooth connection. I believe that this problem may be borderline (not sure if its power, timing, etc.) which is why we see so many issues that are similar, but hard to pin down.
    I also believe that Leopard exacerbates this problem (but not sure yet and way too long to detail now....I'm babbling enough).
    Right now the only way I can get my machine to work properly is to disconnect my printer and drive, boot the machine and then reconnect them after I have logged in. That sequence seems to work.
    I know that isn't any kind of an answer, but you are certainly not the only one and I think this is just another symptom of a larger Apple USB issue. I'm continuing to investigate.
    Good luck all,

  • MAC PRO Internal USB ports stopped working

    Hello, I have a mac pro 8 core with an USB internal ports problem, the 2 in front are not working anymore, and from the 3 in the back only the middle one is working.
    I tried to pull all the power out for a whole night, resetting the pram and nvram but nothing helps.
    When for example I put in a keyboard in one of the ports that is not working and when I power up the machine and I press the ALT key I get the choice of startup preferences, once I select one, and the system boots up the ports stops working, so before the OS loads the usb ports are working !!!
    What to do ??

    This is a hardware failure. While USB ports on the whole are just not designed very well, leading to their failures being pretty common, your issue sounds a bit more like the USB controller chip is failing.
    In any case, the answer is to take it to a repair shop. If they're smart about it, they'll replace the logic board and see if that also fixes the front ports. If not, they'll replace the front I/O panel as well.

  • USB ports problem

    Hi all,
    I have got a brand new laptop Pavilion dv6-2060ea and have noticed problems with the usb ports. I generally use linux as a primary OS but I have noticed the same problem on Windows 7 as well. The laptop sometimes doesn't recognize usb devices as a mouse or an external harddrive, it means when I turn on the laptop boot on an OS, the mouse doesn't work and I have to reinsert it to get it work. It happens 2 or 3 times from 5 boots so it's quite often I would say. The same problem is with the external hdd, have to reinsert it and then it's all right. I have noticed that there has been a new BIOS released and this should fix some problems with usb ports but I already have upgraded to that BIOS(F.13A) and problems persist. I also miss more options in the BIOS about the CPU settings because the laptop has Core i7 and there is no any option to configure the CPU.
    Be patient with my English, please. Cheers, Pepe

  • HP 6730s - Boot & USB ports problems

    I'm having some problems with my HP6730s.
    1. First problem I noticed is that if I keep it running for a long period of time, 2 UBS ports (right side, near DVD drive) stop working and Windows keeps informing me about malfunctioning devices if I have any device connected to those ports. Since I usually have  a wireless receiver for my Logitech connected to one of those ports, I can't get rid of the error not even if I disconnect it. The only thing that works is to turn off the laptop and remove the power cable for 30-60 minutes. This makes me think those USB ports don't get enough power.
    2. I seem to be having problems when I'm trying to boot up using a Linux CD/DVD/USB. I insert the media I wan't to boot up from and I can see the DVD Drive/USB led flickering and then it stops. The Caps led starts flickering and that's it. I have to force shut down so that I can boot up again. At first I thought that it's the media I'm trying to boot up from or the BIOS settings but then I noticed that sometimes it boots up and sometimes it doesn't. I manage to boot up Ubuntu CD after 10 tryouts. openSUSE(11.xx)(the distro I need & use) is very problematic. LiveCDs won't boot up and install DVDs will simply hang on boot. If by any chance I manage to boot it up it pops out a error message and it forces me into failsafe boot/install. I also managed to install openSUSE once but it failed to auto configure videocard so I got stuck in text mode. Trying to manually install ATI drivers failed because it was unable to detect the video card. Same thing happened in Windows when I tried to upgrade the driver using the one on AMD website.
    I bought the laptop in January 2009 and in December 2010 I replaced the battery. 
    I'm now running Windows 7 Professionas SP1 x64 up to date  Also, HP Tools is up to date and I used to test the laptop for hardware issues and nothing was found. I also tested the video card and everything seamd to be fine.

    I found out what's causing this but not how to fix it. I can only prevent it.
    It seams that if you keep the device plugged in too much, those ports won't get enough power.
    The best way to prevent this is to remove the battery when you keep the device plugged in and to also remove it when you turn it off.
    I noticed this won't happen if I keep the device plugged in and ON for a long period of time but only if I keep it plugged in when turned off and if I also keep the battery inside.
    But this will only fix the USB problem, not the Linux boot one.
    What is you problem, exactly? Also, have you found a solution? 

  • HP DV6c63sl USB ports problem, (Unknown Device)..

    I have a problem with my USB ports, when I connect my phone with it's USB cable, it's shown as "Unknow Device" and that's just in my laptop.. My other laptop and Desktop PC can detect it without any problem or drivers, and I have the same exact OS ( Windows 7 x64 Ultimate ) on my 3 PCs.
    I have the same problem with a Game Controller (PowerPad), it works on all the PCs I've tried it on except my HP DV6c63sl. There's just my USB Mouse that works fine, and almost all other USB devices that I've tried are detected as "Unknow Device", And I've got also a "SM Bus Controller" shown in the "Device Manager window" -when I plug in my USB Game Controller- as undetected, I don't know what it is..
    Here's some screens that I think they would help to identify my problem :
    & Thank you very much for your help !
    I really wants my Laptop to detect all the USB devices like my others PCs ( I'm talking about USB mouses, keyboards, game pads, phones with USB cables.. that get detected automatically without installing any drivers )

    Hello Huntrz,
    I understand you are having issues with your Windows 7 not recognising a USB device when it is plugged in. I stumbled across a thread on social.technet.microsoft.com titled USB Device Not Recognized on Windows 7 - USB mouse where they discuss a solution that resolved their issue. Now I know your mouse works, but the point is that a USB device should automatically install that is the whole purpose or USB on a computer devices are to be plug and play. Anyways, what they discuss is that what is called a Hard Reset resolved their issue. I am providing you with an HP Support document: Performing a Hard Reset or Forced Reset that will walk you through the steps to performing a Hard Reset on your Notebook.
    Please re-post with the results as I am curious as well. Thank you for posting this issue on the HP Forums. Have a great day!
    Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

  • Bluetooth Windows 7 USB port problem

    I am using a class 1 bluetooth dongle (unkown manufacturer) with the toshiba bluetooth stack V 8.00.03 Premium, and a bluetooth headset. The specs for the dongle are : Bluetooth V1.2, USB compatible with V1.2/2.0
    I have a strange problem when changing the USB the dongle is plugged into. If I change the dongle to another USB port, searching for devices fails. I have tried uninstalling the stack, and of course deleting the device from the bluetooth manager window.
    Also, strangely , when I plug the dongle into a USB extension on the same port, it doesnt work either. When I put the dongle back into the same USB port it works fine as usual.
    I want to change the USB port so that I can get better reception , as its plugged in at the back at the moment. Also, I want to use the usb extension for the same reason, to bring it out above the desk. Weirdly though,as I say, it doesnt work with the extension (just a regular cable with USB male on one end and female on the other to plug the dongle into.
    Is this something to do with voltage drop down a cable? And regarding the changing of the usb ports is this something to do with the bluetooth ports being installed on that USB port only? I dont know exactly how bluetooth ports work so, how they get installed etc.
    Thanks very much for any help.

    Few questions at the beginning:
    Do you use Toshiba notebook?
    I ask this because, as far as I know, Toshiba supports BT stack on Toshiba notebooks but if you get it as part of package of some other manufacturer they are responsible for support and functionality.
    Until now Ive always used Toshiba notebooks and there is no problem with BT device so I cannot say much about your problem but what you can try is to remove preinstalled software, clean u the registry and after notebook/PC restart install Toshiba BT stack but put BT dongle in the port that you want to use now.

  • GT683 USB Port Problem

  • USB port problem on Mid 2011 iMac (27")?

    I have a Mid 2011 27" iMac running Lion. The USB ports seem to be resetting so that my external TimeMachinne drive disappears. I get the "disk not properly ejected" errors, but no other indicators of a problem. I tried a different usb port, same result. This doesn't seem to affect my wired keyboard, or my iPod/iPad connections (when in use).

    Please do a SMC Reset. 
    Shut down the computer. 
    Unplug the computer's power cord.

  • Mac Pro USB port problem

    The front USB ports on my 2010 Mac Pro aren't working. Every time I boot the Mac, I get a message window - twice - saying they were drawing too much power, and have been switched off, even though they're empty.
    I've tried resetting the PRAM, powering off and unplugging everything and removing the battery from the logic board. Nothing has worked. The two front-facing FireWire ports are working, but the USB ports just won't come alive. Does anyone have any further ideas?

    I would run the Apple Hardware Test:
    Checking for a Hardware Problem
    If you suspect a hardware problem, use the Apple Hardware Test application to help
    determine if there’s a problem with one of the Mac Pro components.
    To use Apple Hardware Test:
    1. Disconnect all external devices from your Mac Pro, except the display, keyboard,
    and mouse.
    If you have an Ethernet cable connected, disconnect it.
    2. Restart your Mac Pro while holding down the D key.
    3. When the Apple Hardware Test chooser screen appears, select the language you
    want to use.
    4. Press the Return key or click the right arrow button.
    5. When the Apple Hardware Test main screen appears (after about 45 seconds), follow
    the onscreen instructions.
    6. If Apple Hardware Test detects a problem, it displays an error code. Make a note of the
    error code before pursuing support options. If Apple Hardware Test doesn’t detect a
    hardware failure, the problem may be software related.
    You may also consider replacing the front panel board.
