• My USB devices are not recognized, but they have a power

  My USB devices are not recognized, the only ones to be recognized are my mouse and keyboard. Each device is powered (motherboard works fine), but Windows 7 isn't their read (although sometimes I'll get a code 43). I have the latest chipset.

  I tried right click and uninstall each device and rebooted the computer. Nothing has fixed this.

  My external hard drive, ipod and other devices that involve the transfer of data seem to ONLY get power and nothing else.

  It is not material because all my devices work on my laptop. Also my motherboard works fine (it's the 2nd RMA) and it has been tested at the factory to make sure of him.

  I would really appreciate help with this

• External USB devices are not recognized

  * Original title: Ext usb devices appearing is not in my computer

  ACer laptop WIn 7 amd a8 quadruple-heart: when I log about 1 T external usb 2.0 or 3.0 hardrives or key USB 64 G,.
  Device Manager displays the devices, but they do not appear in the list of computers. I have other ext hardrives and the keys that operate without problem.
  I have to go to disk management and see that they appear but they do not have a drive label assigned.
  Then I have to give it a label letter manually it will appear under my computer.

  I tried the same features on a laptop HP with Windows 7 without all these questions.

  Thanks RTierra

  I have found a more permanent solution. At the command prompt, type Diskpart

  type

  automount

  If the answer says disabled, type

  automount enable

  Once I did, my USB keys have been recognized automatically when it is plugged.

  Why the setting has been disabled? who knows.

  I hope this helps others.

• Satellite A100-405: after ranging from sleep USB devices will work

  When I bought my laptop about a month ago, I received a message on the peek at the energy of usb hub (I hope it's the right translation, because I have a Dutch version) whenever I have start from standby mode.
  On the windows site, he said that you can turn off this message, so I did.
  But now when I start the laptop to sleep, my usb devices no longer work.

  Can someone please help me solve this problem. Or can someone tell me if it is a hardware problem that can't be solved by returning the laptop for Toshiba?

• But powered USB devices are not recognized

  Randomly on my personal self built computer, readers usb ceased to recognize anything I put in them.  The strangest thing is that the devices kept under tension.  The mouse led would light up and charge the ipod.  I had to plug into an old school mouse and keyboard that do not use usb to use the machine.

  I tried:
  Unistalling/reinstalling usb drivers
  Update BIOS
  Uninstalling drivers for devices (ipod, keyboard, mouse, external hard drive)
  Updated motherboard drivers
  Compensation to reinstall Vista

  I'm really confused on what else to try.

  Data sheet:
  Q6600 2.4
  750FTW
  500 GB WD 7200 RPM hard drive
  2x2gb gskill
  EVGA 9800

  Any ideas would be useful.  Right now, the only thing I can think is to replace the motherboard, but I feel that I would not.  Thank you.

  Hello

• Windows update - USB devices are more recognized after installation

  I had to restart my laptop to install the updates. Once the update is completed, I had 'one of your disks should be checked for consistency. Finally, I uninstalled all recent updates and arrested "windows update". A question, I have (both after windows update installations but also uninstall the updates), is that my USB devices no longer work. There is no error message, it does not detect my mouse or my external hard drive. There is power that the external drive indicates the power and my pad colling runs, it just does nothing. Anyone able to help?

  Also, was not able to run chkdsk - nothing happens

  Have been able to solve this problem by creating an ERD and a running windows repair option. Everything works now.

• Some USB devices are more recognized when plugged after upgrading Fusion 7

  After reclassification of the merger of 6 to 7, some USB devices, specifically webcams is faster to connect to Windows (guest) or Host (osx).

  They also no longer appear in the USB & Bluetooth under the Virtual Machine settings.  Anyone else see this problem?  Try to understand this point, I completely uninstalled merger to try to solve this problem.  Webcams work fine under OSX itself and are usable.

  7 merger supports a virtual USB camera, that can be added as a new device in the virtual machine settings. This allows the physical camera (USB or integrated PCIe FaceTime HD) to share between the host and the VM at the same time.

  There is currently no option in the settings of the VM to UN-hide USB cameras for passthrough to the virtual machine, but it can be done with a preference.

  Edit the ~/Library/Preferences/VMware\ Fusion/preferences file and add the following line:

  vusbcamera. PassThrough = 'TRUE '.

• USB device recognized on Windows 7, but not Windows XP

  Last week, some of my USB devices need not be recognized on my Windows XP SP3 laptop.

  First of all, it happened with 2 external USB HDD connected via a mini USB hub. Connecting them individually did not solve the problem. The error I got was:

  USB device not recognized. One of the USB devices attached to this computer has worked and Windows does not recognize.

  More importantly, the laptop is no longer recognizing my USB thumb drive, which works perfectly on my Windows 7 machine to work.

  Can I reinstall my USB drivers? Just remove the USB devices, reboot and let Windows reinstall them? They need to be specific to the manufacturers of the drivers?

  I deleted it and reinstalled my hubs USB Device Manager etc, but a device is not installed correctly: mass storage controller. It is of course preventing me from accessing the USB and external hard drives. Where can I get the drivers for this if Windows XP does not have? Sure that the key USB is FAT32 (the default format) I went in the properties of the mass storage controller in the Manager of peripheral and copied the device ID. I did a Google search and was surprised to find that it was a card reader. I downloaded the drivers from my manufacturer Web site, and Windows has detected and installed the drivers for the card reader, as well as the mass storage controller. The USB appears in the Explorer, but shows 0 items. I have After the reboot, the USB is not in Windows Explorer, and when I unplug and reinsert an error comes up saying the USB device is not recognized and malfunctioned.

  The solution was to turn off the laptop, remove the power cable and leave it for a few hours, before feeding it back.

  Windows detected and installed the device very well then.

  I don't think that I understand perfectly why he fixed.

  Hello

  I'm having a hard time getting anything out of my F2180 all-in-One printer.

  It worked well for awhile, but now I get a message from Windows Vista saying that the USB device is not recognized and the State showing as disconnected. I tried a number of things that resulted in no results:

  1 installed Driver Detective and updated all my drivers.

  2 disconnected the printer from the mains and the USB cable from the computer. Connected, rebooted and still nothing.

  3 entretienavec the computer on the network. Trendy, rebooted and still not recognized.

  4. run the Diagnostics of the HP. Watch there are connection issues and documents stuck in print, but not able to set.

  I had a glance on the forum to see if others have similar problems, and although some have, no solution seems to come. Don't know what to do now. If anyone can offer help, it would be most appreciated.

  Thank you.

  Just a suggestion, try to change the usb cable...

  or connect any other USB flash drive device and check if it still not encourage recognize...

  some cases, maybe it would chipset issues on your computer if it does the same thing with your other USB devices except the keyboard and mouse.

  Hello

  Have you noticed yellow exclamation marks in Device Manager next to USB host controllers?
  Check it!

  Even if the yellow exclamation points are not visible in the Device Manager I recommend to remove the USB host controllers and root device manager USB hubs and restart the laptop again.
  Wait that all USB controllers will be recognized by Windows and retest your external USB devices.

  Good bye
