• external USB drives not recognized under xp pro 64

  I bought a genuine version of XP Pro 64 to load on my computer and because Win 7 froze with drivers nVidia graphics.

  When I plug a recently bought Seagate Goflex or one of the new Western Digital external hard drives, they are not recognized.

  They do not show on my computer or disk management at all.

  They appear in Device Manager with a yellow question mark big under 'other devices '.

  I right click on the hard drive in the Device Manager to update the driver, and it always fails.

  Before ask you, these USB drives work perfectly on my other XP Home 32 System. The cables are good.

  I tried different ports, front and rear... no good.

  My system XP 64 Prp is updated w/Windows update and software chip to the motherboard.

  Strangely, I have a hard drive WD Passport USB 500 Gb one-year-old that works fine on XP 64 system.

  WD technicians say that I am the only one with this problem. PlugNPlay needs no driver, what do say.

  I also have IDE/SATA USB cable w / the power cable, I use to connect my old internal drives.

  Works fine on the XP Home 32, but I get the error "USB to ATA/ATAPI Bridge" in the device with the 64-bit System Manager.

  Yes these devices are all "turned on."

  Something is missing on the XP 64 system.

  Help is very appreciated.

  Been looking for a solution for a week now.

  Thank you.

• USB drive not recognized on the A30-151 in XP

  After a clean install of Windows XP Pro on a Satellite A30 151, a USB device remains in the category 'Other' (after installation of the graphics and audio drivers, modem) for which no driver seems to be available on the drivers CD. At this point, the category "USB" contains four entries, two standard "Universal Host Controllers" and two "OpenHost' controllers, with the default drivers.
  I suspect that the missing device can be a USB 2.0 "PCI controller host improved USB" from another manufacturer, but Toshiba does not offer a driver for XP for it then it should be supported by the OS (?).
  Any suggestions as to what can be and what drivers need?

  It turns out that XP does support USB 2.0 according to the SP1, it seems a pre - SP1 version of XP Pro leads the native Windows drivers is not available. For anyone in a similar situation, it seems as if a) upgrade to SP1 or b) install the hotfix Q312370)

  http://www.google.com/search?hl=en&q=Q312370_WXP_SP1_x86_ENU.exe

  for the English version should throw a lot of download sites) followed by the autodetection of the native Windows drivers should do the trick. However, the following SP1 problem may come into play

  http://EU.computers.Toshiba-Europe.com/cgi-bin/ToshibaCSG/FAQ.jsp?service=EU&FID=TRO0000001c0d

  in this case, the "NEC PCI to USB Enhanced Host Controller B1" driver required original can be found by searching for "USB driver" for "Windows 2000" for the Satellite A30 Toshiba driver download page.

• Floppy USB drive not recognized when installing WinXP on Satellite Pro L40

  History:

  I bought a Satellite Pro L40, it came with windows vista. I can't stand vista windows for obvious reasons. so I formatted the HARD drive. I have a copy of windows XP.

  IV ' e read on the internet that I need Intel storage driver manager...

  IA´ve got the driver, he got on a floppy, and it does not, because when I start to install XP, it works (after pressing F6 & choose the driver to install). I come to the part of license agreement, press F8 accept...

  I select the partition I want to use (in format completely on vista). It starts to load more stuff... so he said "PLEASE INSERT LABELD - INTEL MATRIX STORAGE MANAGER DRIVER - DISK IN DRIVE A:" "PRESS ENTER WHEN READY."

  The disc that I used in the first place is always in. when I press on enter, nothing NOT to PAST (the USB floppy drive is not yet into action)

  How can I make it work? It is that I can get.

  I DON'T WANT BACK TO VISTA - HELP!

  This could happen if the floppy USB doesn t drive supports the standards of law. Some people have reported on different websites many floppy drives are not recognized.

  However, worry guy. I have a solution ;) (jeaaa: D)

  Try to create a new XP CD using the software called nLite!
  Then, you could include the SATA (Intel Matrix Storage Manager) driver in this new CD and then you could boot from the XP CD again.

  For details and how to use the nLite please Google because there are a lot of useful Web sites.

• HP ProtectTools encryption recovery disk: USB drive not recognized

  I encrypted hard drives of a couple of notebooks HP Elitebook 8560p using HP ProtectTools drive encryption. Saved 4GB USB DRIVE formatted FAT32 discs recovery keys. BIOS and latest available drive encryption versions today.

  Today I decided to test the functionality of recovery. So, when the BitLocker Drive login screen appears at the start, I select Recovery. Then I click on browse to find the recovery on the USB drive key. However, the USB is not visible doesn't help not hit 'refresh readers '. I tested it on two laptops. The system simply does not see the USB drive at this stage (works very well under Windows). Any ideas? I lived the most obvious BIOS settings.

  The USB key is recognized and everything works fine if the laptop is in its docking station, and the USB is connected to the USB port of the docking station.

• USB printer not recognized after Windows update

  OT: usb device not recognized

  After that suddenly stop, reboot, done, the device is plugged in where the printer indicates that it does not recognize the device. I said abattissent unplug it and reconnect it and if it doesn't work me to replace... I re install the driver for the Hpdeskjet940c but nothing works...

  Hello grasshopper.

  This problem may be caused mainly by broken printer drivers, this could have been caused when you installed the updates. I suggest that you start with a restoration of the system on the computer by choosing a restore point when it was working fine.

  a. Click Start, type system restore in the search box and then in the list click on the system restore program.

  b. If you are prompted for an administrator password or a confirmation, type your password or click on continue.

  (c) in the System Restore dialog box, click on choose a different restore point and then click Next.

  d. in the list of restore points, click a restore point created before you started having the problem, and then click Next.

  e. click Finish.

  You can see the following article for reference:

  http://Windows.Microsoft.com/en-us/Windows7/products/features/system-restore

  You can also try driver restore on the computer and check if it helps.

  To roll back a driver in Windows send the driver to the version that was finally installed for the device. Restoring a driver is an easy way to return a driver for a working version when a driver update fails to fix a problem or maybe even a new problem.

  a. open the Device Manager. To do this, click Start, type device in the area Manager search and then click on Device Manager in the list programs.

  b. right click on the device for which the previous version of the driver is desired and then click Properties.

  c. click the tab drivers.

  d. click on Roll Back Driver.

• Error "USB device not recognized" but nothing is plugged

  Hi, this problem recently just started to happen, nowhere I can say. Whenever I turn on my computer or it wake up from hibernation, a message from the task bar appears saying "USB device not recognized". However, there is nothing plugged one of my USB ports. I have three USB ports available, and all are empty. I tested all three ports in something by plugging, and all three ports seem to work well. What can I do to get this message to stop appearing? Thanks in advance!

• Windows 7 - "USB device not recognized" - to load the new electronic Cigarette device. Help, please?

  I have Windows 7 Home Premium.  I just bought a unit of the electronic cigarette, manufacturer is "Innokin Cool Fire IV", the usb charger plugged on Acer laptop and comes to the screen "USB device not recognized".  I loaded different brand before without problem, I don't know what to do and I am NOT GOOD WITH COMPUTERS!  My settings are at "install updates automatically" and I DON'T WANT WINDOWS 10!  Can someone help me please?  Thank you for taking the time to read this.

  This seems to indicate that the charger has actually been detected as a device, but Windows can not work it out.

  Normally such a device should only connect to 5v and 0v pins and have no connection with the pins of data, in this way, that it will not be seen by Windows. I would be concerned by the quality of the device if it has some form of data connection. If you want to continue with this charger, that I would recommend to use a power supply of 5v USB instead of risking the USB port of the laptop, a lot less expensive if it does not. It has been reported several eCig Chargers catch fire. Something like this:
