• One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it. The location is the root (2 ports) USB hub: 1-unknown device and Port 2-not used

  Original title: USB device not recognized

  Over the last 2 weeks, I get a message on a USB device.  The message said that one of the USB devices attached to this computer has malfunctioned and Windows does not recognize it.  The location is the root (2 ports) USB hub: 1-unknown device and 2-unused Port.  I have no idea what it means.  I hesitated to first click the icon (it does not last very long) thinking it could be a scam.  Can someone help me?  Thank you.

  Hi all

  I removed the device and connected to shopping cart, this time I could feel the engine goes, connected to the laptop, new hardware found made my computer explore and didn't find any drive, Device Manager enabled and found it so I uninstalled and reconnected the usb with the same result.
  I don't know what to do next.

  I had a Word with computer store if they could recover some time I wait they told at least 6 hours work, if possible (don't want to shop)
  Bought me another model of the same digital Western not and new power to try to exchange the electronic circuit just in case he finds also the and/or possible fault we power/s but I'm clutching at straws here.

• Problem with the MK6021GAS as external USB disk

  Hello

  I have a laptop that has a built-in drive HARD Toshiba MK6021GAS.
  I found the disk too slow, so I bought a Hitachi travelstar 7200 RPM to replace. That worked without problem.

  But now I want to use the Toshiba HDD USB external drive. But it does not work. On most computers, I get Windows detect the device but then say "an error occurred during the installation of the device" and a few other times, the device is installed as "unknown device".

  The thing is the usb box works perfectly well with all the other readers, I tested (consuming more than my Toshiba) and the HARD drive works fine if I put it inside my laptop again. I tried to Master and selection of cable, same error.
  I tried several computers (so many configs), several catches USB, tried to add external power source... I still get the same error.

  My 2 "5 USB box is"Mobile Disk "... Well well... noname.

  What can I do?

  Ludovic

• Satellite A500 USB problem - unknown device.

  Hello

  Have a Satellite A500 I recently restored to factory from the recovery partition and reinstalled my Win7 upgrade.

  I have a couple of unknown devices in Device Manager and have no way of knowing what they are.
  They would normally be a problem for me except that I'm also the sounds of disconnecting USB every now and then and caveats relating to the devices being plugged into a port USB2 not high speed.

  I have of course plugged anything in time so I expect there is a device which is malfunctioning and not detected correctly.

  The devices I first suspected (webcam, TV Tuner, touchpad) all normally appear in Device Manager so I'm at a loss as to what is the cause.

  Any ideas?
  Beards

  Hello

  I understand this correctly?

  You restored the A500 to the factory settings using the Toshiba recovery procedure and the unknown devices still shows up in the Device Manager?

  That s strange because the recovery disk to put the laptop in the same State as on the first day of purchase. So generally unknown devices should not appear and all drivers must be installed correctly.

  However, I found an interesting and in my eyes useful HowTo document that should help you to know which drivers are missing in your case.

• Problem with Satellite Pro 4200 series USB (4270)

  Hello

  I'm having a problem with my usb port, it doesn't seem to work properly. I did an update of the Bios, which solves nothing. I changed the drivers (Windows 2000 Professional service pack 4) which did nothing either. Plug-and-play does not activate even when I plug something into the usb port. At first I thought that maybe the USB has been damaged, but when I plug my webcam, it lights up briefly, and since it is powered from the usb, I hope this means that the usb port still works. I tried to plug in scanner m, my printer and my camera, with all the different drivers, with which they came. Nothing works. Windows 2000 displays not all conflicts with all the drivers. I've also disabled in BIOS, all other ports (LPT1 COM1 COM2) using the IRQ11. What could be a solution to this problem?

  Hello

  Well, as far as know that the operating system is unable to recognize the devices if the external USB device needs more power than the USB port provides. In this case, the USB devices must have an external power supply.
  In addition, try to remove the USB port on the Device Manager and restart the operating system.
  After the restart of the operating system should recognize the USB ports. Maybe this procedure solves the strange USB problem.

  Please let me know if it works.

• "Unknown device" USB Barcode scanner, problem with the USB controller driver?

  Hello

  I need assistance with our Barcode Scanners that doesn't work on our newly purchased computers at HP with Windows7 Pro x 64 operating systems.

  The brand and model of the bar code scanner is:

  Datalogic Heron D130 USB.

  When you connect the scanner to a USB port, Windows will try to install this as a HID, but it takes an unusually long time, about 7-8 seconds, to boot the device and install the drivers and appears as an unknown device in windows "devices and printers" and the hand scanner does not work.

  Sometimes when you move the USB back can I sometimes the scanner at hand to be recognized as an HID device or a Datalogic barcode scanner,

  It works fine until you restart the computer.

  After restart the computer cannot detect the scanner Barcode correctly without re - appears as unknown device.

  I suspect that there is a compatibility problem between barcode scanner and card USB controller on the computers.

  I tried to update all the drivers available on the website www.hp.com and same www.Intel.com (chipset drivers) but nothing has helped to solve this problem

  Tried newly bought barcode scanners and "used" barcode scanners earlier who works on other computers, but the problem remains.

  I found a workaround by connection of bar codes in a USB hub, and then plug the USB hub to the computer.  And leave the USB - hub to take care of the communication with the Barcode Scanner.

  in this case, it takes about 2 seconds for the code scanner barcode to mount correctly in windows under the heading "devices and printers" and then works perfectly, even after a reboot.

  I googled after a response after my problem, but it seems I'm the only one who experience this issue. ?!

  Bought more than 40 computers that I have this problem.

  These were bought at different times with two different for suppliers

  Computer model are the following

  HP ProDesk 1 400 P/N5S21EA

  Specifikations:

  http://WWW8.HP.com/emea_africa/en/products/desktops/product-detail.html?OID=6614160#! tab = specifications

  Does anyone have an idea what could be wrong and how to fix it?

  Hello

  The problem is not power - related.

  We use passive USB hubs that solves the problemon these computers.

  (it also works with the docks, or if you EliteDisplay E241 HP as we thers a usb hub 2 ports inbulit in monitor that works.)

  The problem lies in the incompatibility between the Intel USB controller and the hand scanner, can be connected to USB 3.0

  When you let another usb-controller support in handshakeing (such as a usb hub), it works.

  Datalogic or Intel would like to acknowledge this error.

  Because none of the big companies want to acknowledge the problem or repair, personally chose to switch to an AMD platform / CPU instead of the Intel and now it works fine!

  We get more performance for your money when AMD is usually less expensive to purchase.

  And because of the poor of Datalogic press where they don't even answer e-mail (their only channel for support)

  I chose to stop using their products. I'm going to use another provider / brand of barcodescanners.

• Toshiba 3.5 "3 TB USB 3 to HDD - unable to create partition using Mac OS

  Hi guys,.

  To my knowledge the Toshiba 3.5 "3 TB USB 3 to HARD drive supports the file format NTFS (for the support of the Windows system).

  I guess you must re - format the HARD drive to the system of files HFS + for Mac compatibility

• IPod Classic 7 G 160 GB ' there was a problem installing this hardware: Apple iPod USB Device ".

  I have recently (June 2014) bought a brand new Ipod Classic 7 G 160 GB Model A1238.

  Whenever I connect via USB to a PC running XP SP3 and Itunes V10.0.7.2 it is always treated as if it were a new connection, i.e. "new hardware found". After trying to install it, it says so "cannot install this hardware" and "there was a problem installing this hardware: Apple iPod USB Device."
  I have also a 2009 16 GB Ipod Nano 4 G model 1285 and this is recognized by the PC whenever it is connected through the USB port itself.
  I connected the Ipod Classic 7 G to a laptop running Vista and Itunes V10.0.7.2 where the Ipod is recognized and installed.

  Even if the PC States that there is a problem installing the Ipod, it still appears in Itunes and I can download music to it and disconnect by using safe mode disconnect.

  PC XP SP3 - Ipod Classic
  I watched "Device Manager" under "Drives", the Ipod Classic is listed as an "Apple Ipod USB Device", but has an exclanation score against it.

  Right-click on the 'Apple Ipod USB Device' properties and the "Volumes" tab it shows the drive with the exact name and the size of the data, by clicking on the properties of "Driver" tab it says 'Unknown' driver provider, driver Date and Driver Version as being "not available". By clicking on the "Driver Details" properties, it shows a driver file-

  C:\WINDOWS\system32\drivers\PartMgr.sys, File Version 5.1.2600.5512 (xpsp080413-2108).

  Under "Device Manager" USB controllers, there is an entry for "Apple Mobile Devices USB Driver" and a "USb Mass Storage Device"

  The 'Apple Mobile Devices USB Driver' lists two drivers:
  C:\WINDOWS\System32\Drivers\usbaapl.sys and
  C:\WINDOWS\System32\usbaaplrc.sys

  The "USB Mass Storage Device" list a driver:
  C:\WINDOWS\System32\Drivers\USBSTOR. SYS

  PC XP SP3 - Ipod Nano

  I repeated the steps above with the Ipod Nano, connected to the PC and the driver provider is presented as Microsoft with the driver as 07/01/01 Date and Version of the driver as 5.1.2535.0.
  In the "Driver Details" properties, it shows TWO driver files:

  C:\WINDOWS\system32\DRIVERS\disk.sys AND meanings
  C:\WINDOWS\system32\drivers\PartMgr.sys.
  At the same time with the Version of the file 5.1.2600.5512 (xpsp080413-2108).

  The 'Apple Mobile Devices USB Driver' and "USB Mass Storage Device" are the same as for the Ipod Classic.

  I followed the procedure to remove Itunes and even the update to Itunes to V11.2.2 nothing works.

  I am aware that the system is also that XP can now be updated.

  So, why not not Windows Installer Ipod Classic and why the disk.sys driver does not appear

  According to the details of the pilot?

  Is the 7 G Ipod Classic not compatible with XP SP3?

  Yes it is compatible with XP SP3.

• Satellite P200 1EE problems with playback HD video and USB ports

  I bought the laptop Satellite P200-1EE dixons for and I'm happy with it in many ways, but the main reason I bought the 1EE P200 was because of its potential to play and edit the video high defintion.

  I can't seem to play or watch video clips high definition without them being clumsy and with a frequency of images at 3 frames per second, and not the 30 frames per second, he must turn.

  The clips I'm playing are some MOV files record on my camera at 1280 by 720 resolution at 30 frames per second and the two Quictkime player and Realplayer they simply are not quite smooth. Given that the laptop has a DVD player high definition and a high-end graphics card ATI HD 2600 ispecifically intentional for high defintion watch a DVD high defintion to 2040 by 1080 I do not understand why he should fight with playback relatively low resolution video files.

  I would edit 720 video high definition and the speed of the processor, the speed of the bus, ram and graphics card should be enough for this high defintion video simple editing, so if he can not even play video high defintion, what chance does he have to edit video high defintion?

  After only 2 days of working completely fine Vista Vista completely crushed and the computer refused to restart. I had to use the recovery disk and completely wipe the hard drive. not a good introduction to vista which, apart from that, it was very slippery. After you have installed Office 2003 it works completely fine on Vista Home premium

  Does anyone have suggestions or solutions?

  Hi Daniel

  To be honest you message confuses me.
  The recorded movies (.mov files) are not format true high definition as in movies on HD DVD or Blue ray!

  I think you need to convert these files first in a format mpeg mov or avi format and then you can try to play with ordinary players like WMP, Real player, etc.

  Here are some useful tools;

  Converts mov to mpeg

  Convert mov to avi
  http://www.JakeLudington.com/ask_jake/20051003_convert_mov_to_avi.html

  With regard to the question of the USB.
  Try to remove the USB port on the Device Manager and restart the laptop. After restarting again the USB ports should be recognized again and the USB driver should be updated.
  In most cases, this enables the USB flash drive.

• Portege M440 - Vista problems: problems of Bluetooth, the unknown device and tablet.

  I just installed Vista on my Portege M400 and installed all the drivers on the driver Vista page.
  But I have several questions...

  1: bluetooth does not work. I can't find anywhere in Control Panel whatever it is on a connection bluetooth or something else.

  2: after you have installed all the drivers on the driver Vista page, there is 2 "unknown device" in Device Manager. I can't find any information on what are these devices. However, when I tried to manually install the driver bluetooth on the first of them "Unknown device" he admitted the driver. This does not work on the other. And it does not solve the problem of the bluetooth missing.

  3: the tablet itself feature works very well - the pen and everything. But when I turn the screen into tablet mode it does not change the screen layout. Or the buttons on the lower part of the screen to work.

  I hope that there is some sort of solution to these problems - and that someone can help me.

  I am also very interested in these drivers because all I know Toshiba Vista drivers are not available at this time.

• Tecra S2: HDD as unknown device on two of the three USB ports

  Hey again,
  I thought then that I was here anyway I could ask this too.
  The tecra S2 has 3 USB ports, they all work very well for my USB mouse and other small things like the wacom tablet...
  But when I plug my external hard drive in two of them, it says that it is an unknown device...

  I think, but am not sure, that this might have something to do with something once, we had to do in school;
  We had once set up a pilot for a small converted Converter a series (or parallel, cant he recall) cable to the usb port
  (I have already uninstalled the drivers but nothing has changed)

  It's just a guess...

  any idea on how to solve this little problem? : p

  Hello

  You said external USB HDD appears as an unknown device on two of the three USB ports.
  What appears if you connect the HARD drive to the USB port on third?
  It appears as an unknown device or what?

  The device usually appears as an unknown device in device because manager not installed device drivers.
  I check the HARD disk for the drivers and try to install it again.
