Another USB no tworking problem

So I got a brand new iPod yesterday and plugged it into the USB port on the left hand side, no problem. Charged up, data transfered, yada, yada. I shut the computer down and went to bed. When I turned it on this morning, my USB port no longer sends data! It gives power, but not information. Anyone ever heard of such a thing?

Welcome to Apple Discussions!
Are you saying you removed the iPod, and connected a thumb drive or another USB data transfer device and it wouldn't allow you to transfer data to it via that port? Or are you saying that it appears the iPod won't receive any more data? If the latter, once synchronized the iPod will simply add new songs/books/movies/etc... as you add them to iTunes. Are you saying you added another song to the library, or a new playlist and it didn't transfer to the iPod?

  • Windows 8 USB 3.0 Problems

    I have run into many USB 3.0 problems across multiple devices and computers running Windows 8 Pro 64-bit. After many headaches and sleepless nights I think I have narrowed all the problems down to one thing in Device Manager:
     "Intel (R) USB 3.0 eXtensible Host Controller -0100 (Microsoft)”
    The controllers (Multiple Computers) have had problems with all the Microsoft Drivers including the most resent: 6.2.9200.16548 3/1/2013
    The problems:
    USB 3.0 External Optical Drives (labeled Windows 8 compatible) not recognized or continuously disconnecting/reconnecting with or without manufacturers drivers.
    USB 3.0 Flash drives running slow and/or disconnecting often with data corruption/loss
    USB 3.0 Flash drives not recognized
    My solution: <Disabled> “Intel xHCI Mode” or “XHCI Pre-Boot Mode” in BIOS/Firmware
    This solution Takes the
    "Intel (R) USB 3.0 eXtensible Host Controller -0100 (Microsoft)” out of Device Manager and eliminates all the problems stated above across multiple machines running Windows 8 Pro 64-bit.
    However: This is not a fix.
    The Intel USB 3.0 controllers on the machines seam to only run at 2.0 speeds. (Before they were also slow but much less functional, often not recognizing devices)
    Non-Intel USB 3.0 controllers are fully functional at full USB 3.0 speeds. (Before they had limited or no function depending on the controller)
    This appears to be a fix for non-Intel USB 3.0 controllers but what about the Intel controllers that take the lion’s share of USB 3.0 controllers on the market?
    Dose Microsoft have a fix for
    "Intel (R) USB 3.0 eXtensible Host Controller -0100 (Microsoft)”
    Is there a new Microsoft driver coming out soon? How about an Intel driver for Windows 8 like the one they have for 7?
    Am I the only one who is being slammed with this problem from every windows 8 machine I touch? I have not seen a large amount of discussion on the internet with such a seemingly big thing like USB 3.0 not working with Windows 8!

    Hi I guess I am going to add a few more flies to the ointment.
    I have a serious issue with USB 3.0 and I would like to hope that somebody may have an answer even if they are unable to help.
    I run three different computers, for three completely different purposes, they are of different makes, One is an Acer, the other is a Pryon and the third is a Toshiba, I also have 2 Toshiba laptops, one brand new running Windows 8, the other running
    Windows 7. So basically what I am saying here probably has nothing to do with the systems I am running.
    I guess a lot of people are getting swindled here by the hard drive manufacturers and everyone here seems to be blaming it on windows. I have spent thousands of dollars replacing all my old 2.0 drives (and some were getting a bit tired) with these new fangled
    super duper super fast 3.0 drives. I think overall in the past year I have bought around thirty of them, mostly portables, but some desktop ones, all different brands too I might add, Seagate, Western Digital, Toshiba and Samsung. This as you can imagine has
    cost me a lot of money. The data I had on the old 2.0 drives equated to about 20 years of my life. Out of the roughly thirty I have bought, nine of them have bit the dust so to speak. Nearly all, once they become unusable, come up with the same thing, "The
    last USB device you connected to this computer is not recognised.
    As an example I will recount exactly what has occurred with the last one to fail, which was today about 4 hours ago as I write this. It was working perfectly fine this morning, never gave off one indication that it may be about to fail. Then after a restart
    (which incidentally I am wondering if anyone else has this problem whereby once they shut down their computer they have to either power off or remove every USB 3.0 device from their unit before the computer will even start - this happens on two of mine - but
    not on the Toshiba)
    So I shut down, I am using a powered 9 port hub for most of the portables on this particular system (Pryon) which I have to power off so all the drives disappear else the computer just hangs at the boot screen until I have done this) I have one 2,0 disc
    connected which I don't need to remove for the system to start.
    Anyways once I have restarted the computer I then re-power up the hub and all the drives are loaded again and away I go. Well that was all good except when I checked one of my drives was missing from the File manager that I use (Salamander) and also not
    showing in Windows Explorer either. So I trace down the culprit, unplug it and re-plug it back in. Lo and behold up comes the afore-mentioned windows does not recognize this device. This is odd given that there are five other drives of the exact same make
    and model attached to the same hub still working. As I don't have all the slots in the hub filled I decide to change the slot and plug it into a different one. Same result. So then I decide to plug it into a 3.0 slot connected directly to the box, same result.
    As a last try I then plug it into a 2.0 slot on the box, same result. So then I take it out and try it on the other two boxes and eventually the laptop...same result....
    I now have nine of these contraptions all totally useless to me....yes I guess I could send em back to Seagate and Toshiba and Western Digital and they will replace em with a brand new one...clean as a whistle with my twenty years up the poop chute....
    I have looked everywhere through Google trying to find someone or somebody with the same problem as me, surely I cannot be the only person in Australia that happens to keep on getting the duds.
    I've had 2.0 drives that have lasted ten years or more and probably may have went another ten if I didn't keep so called upgrading....some of these that have failed on me are not even 3 months old. I even had one desktop 3.0 drive that I bought on the Wednesday
    in Adelaide and by the time I had gotten it home after my son had copied some stuff onto it..it wouldn't work.
    I have tried just about everything I've ever read on these forums, like using a different cable, Ive even pulled one of the portable to pieces to be able to use an attachment that I can plug it directly into a 3.0 slot and still nada....
    My newest laptop is still under warranty and I have had that back to the supplier twice with a main hard drive failure which they have had to replace.
    The reason why I am suggesting here that it may not be all windows fault is that my other laptop is still running windows seven and once a drive cacks it it wont show up in that either....I will say this though, I only have one drive that I use in that laptop
    and that is still running well.
    Now before everybody jumps down my throat I have checked thoroughly for viruses on all my boxes, and they all are clean. And in anycase I've never heard yet about a virus that can attack one hard drive only, given that all that is on there is music, just
    like the other six.
    Unless windows eight itself somehow manages to render a hard drive useless somehow then it has to be a fault in the manufacturing technology and that even though a drive might work perfectly for a week or two there is something there that the manufactures
    are missing in their testing.
    Like someone said earlier, maybe it is going to take some massively big law-suit from a huge company that has lost everything against somebody for them to realise that USB 3.0 is tainted and no good.
    Do they still make 2.0 cause I am going back there and hopefully I can do it before I lose everything, even though it will take a good part of six months to copy back over whatever it is that I still may have left....
    Like I said I don't expect any answers but thank you for taking the time to at least read this...
    Cheers Vern

  • 500 GB external USB hard drive USB 2 configuration problems

    Hello Sirs.
    I recently adquired a 500 Gb external USB hard drive part number PX1269E-1G50.
    I have some problems with the USB 2.0 configuration in windows XP. When i connect it to an usb 2.0 port i receive the message "High-speed USB hard disk drive plugged into a non-hi-speed usb hub", and the device stays in low USB (12 mbits/s) speed. (I checked the port with another usb 2.0 peripheral and the port is working in usb 2.0 mode correctly).
    I checked the PXI1269E-1G50 in others pc and i have same results. I cant get it to work in USB 2.0 mode. I also have some problems with the virtual CD partition that is always present when you insert it and mount. Exist a way to remove it ?
    I only use the hard disk for daily data back-up and i don't want to use any more drive letters in my system.
    The main PC is an ASUS P4P800-E deluxe with windows XP SP2 fully updated and build in USB 2.0 intel controller.
    Best regards
    PAMF

    Hello again everybody
    OK. Finally i had to send the disk to my dealer. Toshiba in Spain says there is not solution. Sorry. This is an erratic product. Sometimes with one cofiguration simply works and sometimes with a different configuration does not connect in USB 2.0 mode. I don't want such a product in my desktop... and the Virtual CDrom is impossible to turn off. (I'm not interested in security tools. I only want to make daily backups)
    Thanks to everybody in the forum for your help.

  • IPod stopped sync. just sync when you plug another USB device, e.g pendrive

    As weird as it may seem all my iPods (i have 2 old Nanos, 2 new Nanos, one Shuffle and one Touch)stopped syncing. iTunes recognizes them without a problem. I can configure them to sync to a particular playlist but nothing really happens.
    After a lot a work (plugged them in another PC to have 'em erased and all; reinstalled iTunes 9, etc) I just found out the strangest behavior: if I click Sync it takes a long time and nothing really happens. If I do it again anfd plug another USB device (like a pendrive) then sync goes smoothly.
    Not sure why.. all I know is that I love the hardware but hate the software.
    Maybe if I reinstall my PC the issue will go away...
    Any ideas???
    <Edited by Host>

    It's probably not a problem with the shuffle.  Your computer's USB bus may not be providing enough power for all of your connected USB devices.  A typical USB mouse and keyboard are low-power devices, so you must have other devices connected...?  An iPod, because it charges battery from the USB port, is a high-power device.
    I use a powered USB hub.  The hub has its own power supply.  I have the hub connected to the computer, and most of my devices, like iPods, iPhone, flash drives, etc. connect to the hub.  I use the USB ports on the computer for things I leave connected more or less permanently, such as printer and external drive.
    Since the hub has its own power supply, devices connected to it do not draw power from the computer's USB bus.  So that is important.  Some cheaper USB hubs are not self-powered; they are powered by the computer's USB port.  I use an older version of this one
    http://eshop.macsales.com/item/NewerTech/USB2HB7PRO/
    but there are many options.  Just get one that has its own power supply.

  • Usb transfer rate problem with bootcamp

    hello
    drivers for uEye cameras are only available for windows platforms. so i am running windows xp on the latest mac mini with the latest bootcamp drivers in order to use the camera.
    everything works great until i plug in another usb device. the transfer rate of the camera decreases dramatic (1/2). the second usb device is an usb hub with a microcontroller. it consumes only low transfer rates.
    this constellation works perfect on other pcs. i can't compare it on os x because no drivers for the camera are available.
    are there known issues with usb transfer rates on intel mac minis? firewire cameras and harddrives should suffer similar problems.
    greetings
    michael

    are there known issues with usb transfer rates on
    intel mac minis? firewire cameras and harddrives
    should suffer similar problems.
    Welcome to Apple Discussions!
    To address this specific point - no, there are no known issues with USB transfer rates that are common to Macs but not PCs. The weakness of the USB standard is that it is controlled by the host system rather than a dedicated controller, thus transfer rates (on both Mac and PC platforms) are determined by what the system is doing overall. As a result, transfer rates vary quite dramatically. Firewire, on the other hand, has a dedicated controller which ensures that a consistent data rate is achieved, almost regardless of other system activity. That's why you will often see it recommended that FW is used for external drives rather than USB, since while USB will generally provide better burst rates of data transfer, FW will generally provide far better sustained data rates, despite being theoretically slower.
    In your situation, I can't help but wonder if the hub you mention is not causing the system some issues. It would not have to be a matter of it causing any significant data transfer itself, but could be the result of the hub's controller forcing the system into activity which then suppresses potential performance from the camera.
    One thing is sure: if the camera works well without the hub connected, but degrades in performance with it, the issue is not with the system or the camera, but the hub.

  • ASUS M5A97 USB 3.0 Problem

    Even though my ASUS M5A97 has USB 3.0 i get this error: Check your USB controllers for Kinect Windows v2 compability
    Result: No supported USB 3.0 port detected
    I saw that back in November another person had the same problem and the only solution was to get a standalone USB 3.0 PCIx Gen 2.0 card that has an Intel or Rensas chipset.
    Is there anything new to know? Or is this still the only way to get kinect v2 to work on motherboards that have different chipsets?

  • I'm new to apple after years of MS OS! How do I transfer files from my USB memory stick to another USB memory stick? cheers

    hi all, i've just switched to apple after many years using MS OS!  I'm now using iMac desktop 21.5" with 2.9GHz processor and latest Yosemite software.
    How do I transfer files from one USB memory stick to another USB memory stick on the iMac?  cheers, linley94

    Plug in the memory stick and it should open then create a New Folder and drag and drop the contents from the memory stick to the new folder you created. Remove the original memory stick all the information should be in the new folder you created. Now plug in the new memory stick with nothing on it when it opens drag the folder with the contents from the original memory stick folder and all into the new memory stick that opened and there you have it.
    CHEERS

  • I have problems printing with a HP Officejet 6500 printer directly from my iMac. The printer itself does function well, as I can print from another PC without any problems. Does anyone have a clue?

    I have problems printing with a HP Officejet 6500 printer directly from my iMac. The printer itself does function well, as I can print from another PC without any problems. Does anyone have a clue?

    Hello:
    I must apologize  .  I should have checked here first:
    http://support.apple.com/kb/HT3669#HP
    According to the list, there is no driver for your printer included in OS X 10.7.
    There are a couple of options:
    1.  Contact HP to see if they have a workaround.
    2. If the model of printer is not listed but your printer is a PostScript printer or PCL Laser printer, try the "Generic PostScript" or "PCL Laser printer" drivers.  Generic printer drivers may not let you access all the features of your printer.
    I have not tried #2, but some people have had success.

  • Can I copy HP Recovery Media to another USB flash drive?

    Hi. Just a couple questions please: 1. When I make the one time only "HP Recovery Media" to a USB pen drive, can I then "copy" and "paste" to another USB flash drive as long as the 2nd flash drive has enough capacity?The Recovery will still work right?I ask this in case I need to change to another USB flash drive and I am aware that I can only have one copy of the HP Recovery. 2. If that is the case, I then can also make a backup to an external Western Digital drive so that in case of malfunction of the USB flash drive I can always transfer the files to another USB flash drive? Thanks in advance for the reply. Best regards. 

    Hi, Copy and paste won't work. Please try the following method:    http://h30434.www3.hp.com/t5/Notebook-Operating-Systems-and-Software/This-is-how-to-make-a-2nd-set-of-recovery-disks/td-p/1694703 Regards.

  • My USB Ethernet connection drops when another USB device is plugged in?

    I have a MacBook Air (Mac OS X 10.6.7 but it happened with older OS versions, too) and have a few issues with my wired ethernet connection. (through USB Ethernet adapter).
    1. When I have the USB adapter plugged in when I wake the MacBook Air up it won't be recognised (have to plug it in after wake up)
    2. (that is more annoying).When I have the Adapter connected and I plug in another USB device (like a USB stick) into the other slot, my USB EthernetConnection drops! Only once I unplug the adapter and plug it back in it works again.
    Is there maybe a firmware upgrade that should be installed or something??
    Does anybody have an idea???
    Thanks

    Hi, you can upgrade the Firmware for the wrt54g router under the system screen.
    you will find the "upgrade Firmware" tab under the system screen.
    Once the Firmware has been upgraded you can then reset the router by holding and pressing the reset on the back panel for 30seconds. And then reconfigure the router again.

  • K9VGM-V USB 2.0 problems

    I'm assembling systems based on K9VGM-V motherboards.
    They all have the strange behaviour that the front USB 2.0 ports , not always are recognised by Windows as 2.0
    Sometimes they are reported as 1.0.
    The USB ports on the back of the motherboard , are always working as 2.0.
    Tested other brands of motherboards in same cases with the same USB apparatus , no problems.
    All the K9VGM-V boards i tested have the same strange behaviour.
    Who can help ?. Even bios update did'nt solve the problem.

    MSI's USB configuration has the #10 pin set as OC(overcurrent), but many cases have a 9th wire(you only need 8 wires) leading to the #10 pin as a GROUND. This is where the problem occurs.  It is likely, that the "other" MOBOs that work may have the #10 pin, but it is not electrically connected and that's why you don't have an issue. BTW, Have you checked to see if you can remove the wire leading to the #10 pin on the USB header block of the case?  For my case, there is a tab you can lift to pull out a wire.  If you aren't going to cut or remove anything, then I guess you'll need to get a USB PCI card and use that instead.
    MOBO drivers are the chipset drivers; the VIA 4in1. http://global.msi.com.tw/index.php?func=downloaddetail&type=driver&maincat_no=1&prod_no=260

  • A85XA USB 3.0 Problem

    A85XA USB 3.0 problem
    I've been using the A85XA a problem with the connection from the board to the USB3 front panel on a Corsair R400 housing. A 3.0 port on the panel can be connected to a USB 3.0 drive is off and log on again continuously. The other connection works fine. The same behavior also comes in a 3.0 2-port cable which is plugged onboard. One works, the other "pulses". I put the plate on any 2.0 port, the drive is running without hesitation. Could it be that delivers the power from the onboard power connector different?
    Used google translator ;-)
    If further input needed, please ask.

  • Another usb printer-to-Airport Extreme problem

    This issue is similar to Tanya Howie's, but involves an HP 5440 printer instead of a Pixma. I have the G4 iBook connecting via Airport to the Airport Extreme, the iMac Snowball hardwired to the AE via Ethernet cable, with the HP plugged in via usb to the AE. I have reinstalled the AE software 7.4.2, the HP software 5.3, and the Airport utility 5.4.2. Also, I connect to the internet via RoadRunner thru Warner Cable.
    Occasional disconnects have been cured by resetting everything back up, until recently. Now, when I look at all the places where the printer should appear, I see it listed: in the Airport Utility settings, on the printer setup utility, the File dropdown Print command, in the dropdown Printer box and choosing Bonjour version of the HP, even in the Opening Connection box, which shows the attempt at opening the connection; the connection bar shows an attempted Print, then goes to Job Stopped.
    When I run the Print Diagnostics that is in the HP 5440 menu bar, I get a green light on Airport, Airport Settings, Network Settings, ISP, and Internet, but a red light on Server, which also says Failed. If I click Continue and go thru the steps of the diagnostics, the last page says "Cannot connect to server: Networks Diagnostics was able to connect to the Internet, but not to the server 'HP Deskjet 5440 printer.riousbprint.tcp.local' . This could be caused by problems with the server, or an Internet problem between this computer and the server."
    Where is this server, and can someone tell me how to address its issues or to find a work-around? And is there a step I have missed? Thanks!

    I rolled back to 7.4.1 to try to fix my dropouts and slowdown problems, but that didn't make any difference. So I went back up to 7.4.2, but did the hard reset by
    1. unplug Airport Extreme
    2. Press in reset button on the back and hold it in while...
    3. Plug in power
    4. After light on the front started to flash, released the reset button
    I then had to reset all the networking settings (password, SSID, etc) but that only took a few minutes and a couple of resets. The network dropouts haven't happened again so I'm hoping that has sorted it. The printers seem to be behaving themselves as well now. I did roll back to 7.3.2 at one point, but then I lost the printers completely with that and Snow Leopard (Leopard was fine though).
    There was a posting I found from somewhere that said about setting up the printer using the IP connection setting rather than the automatic one, but I can't remember where I found that. Let me have a quick think...
    Ok, I think this was the page (the instructions are very similar anyway)

  • Another USB Ethernet problem

    I've read all the post regarding this issue. All of a sudden my wired internet connection can not be established. The USB port and ethernet adapter work fine (I checked them). I try to set up a new connection and it 1st says No Ip address and the light is yellow, but then I get that there is not ethernet plugged into my computer. Frustrating. The air is not reading my ethernet. Any help?Thanks.

    I am tempted to do a full OS reinstall as this has helped some people. The reinstall option has been the only one that Apple has provided. I would rather they (apple) not get in the habit of using "reinstall" as an option for their own QA shortcomings.
    What if anything have you done to insure that the system installed on your Mac was free of any defects before you applied the update? By far the most common reason reinstalling the OS fixes update problems is that some part of the system was compromised after the OS was originally installed. Unlike installing the OS, which runs under the control of an external copy of the OS, an update runs under the control of the very copy of the OS that is being modified. Thus, a corrupted system file, a third party modification, or any of a number of other problems that can go undetected in normal use can interfere with the proper application of an update in ways that are very hard to differentiate from a problem in the update itself.
    IOW, it is Apple's responsibility to provide products free of QA shortcomings, but the user's responsibility to make sure those products do not become damaged or adulterated after they are delivered. Apple provides some tools (like Disk Utility) that can detect & repair some damage but it isn't practical for it to provide tools that can detect or repair every possible problem. For these, reinstalling the OS is a more practical & often much quicker solution.
