New x120e - "Unknown device" under USB controllers

Similar Questions

• 802.11 wireless pen drive recognized as 'unknown device' under USB. Help, please.

  Specs: Windows XP Home Edition version 2002, Service Pack 2. This is the version of XP OEM. Processor Intel pentium 4 2.00 GHz. 1.50 GB of ram.

  After an unknown incident (i suspect headphones usb), my wireless USB key has ceased to be recognized as such and become everything simply an "unknown device" under "USB bus controllers. Although windows tells me there is no drivers for the device installed, the wireless pen drive is signed with the Publisher of Microsoft Windows with a version of driver 5.1.2600.0, Microsoft being the driver provider.

  Compound number, the 802.11 device is listed under "Other devices" when 'show hidden devices' is selected and the variable "devmgr_show_nonpresent_devices" entered "environment variables", but is washed out-showing that the system thinks that the device is not currently connected to the computer. In addition, under details, it displays error code 45: the device is not connected to the computer. And it is. It's very hip. as cement and connected tape.

  I plugged the wireless key USB in all the usb ports on the computer, every time with her recognized as 'unknown device' under usb controllers. I entered in the safe mode, uninstalled all the usb controllers and root usb hub drivers and let windows the respawn after reboot in order to solve the problem. No dice.

  I also plugged the USB in a different desktop and it works like a charm, so the issue is not with the hardware.

  Clearly there that a conflict with drivers/registry/God knows what, but I'm at a loss. Somehow, windows has taken its decision and the player associated with "unknown device" and I see no way to make the system "forget" that the USB was never connected. How can I remove the ghost driver "unknown device" manually or force windows to re-associate the key wireless USB with "other devices" (with the yellow? mark) and not this useless usb driver "unknown device"?

  Thanks for the help!

• Unknown device under USB on my laptop Satellite L500-1XZ

  Hello

  I'm new on this forum, but not new to the use of Toshiba products.
  Anyway, a few weeks ago I started having problems with
  My USB ports in the sense that they all started to die one by one: first
  the upper right corner, then the bottom to be followed soon after by the Sata/USB combo
  port on the left (kept my adapter mouse there).

  I have not used anything other than the regular on my USB ports, you know memory
  sticks, HARD drive external (I used a Toshiba StoreArt 1 TB), my mouse and just about it.
  Naturally I started looking for a solution to my problem and tried everything, except
  for an update of the BIOS.

  I don't know what else to do, so I hope that smbd after dealing with the same problem
  can help me to restore my USB ports feature.

  I'll post some screenshots:

  Hello and welcome to Toshiba support forum.

  On this virtual path, it is not easy to tell what the problem is here and give you an accurate diagnosis. In my opinion BIOS update is, for now, is not necessary.
  I put t know if you have installed some software additions for use with an external device but you can try now is to reinstall the chipset driver.

  I checked the Toshiba download page and your laptop is supported for Win7 32 and 64 bit so you can find it there. I wanted to post the link here, but I put t know what version are you using.

  Please, do it in a first time and post comments.

• Device Manager Catagory says "Unknown" instead of "USB controllers"

  

  I have this in my device manager - all my USB devices work OK.

  More I-

  

  It's my network page, but my network connection works OK.

  How can I fix it?

  Dean

  Hi Dean,

  I understand that your USB drives and internet connection works properly but it does not appear correctly in the Device Manager page and the network as appropriate.

  This problem could occur if the drivers were not properly installed or was unable to configure. As a Reader USB usually works if the default driver/generic drivers are present in the system. But as you rightly mentioned that gets listed under USB controllers.

  To better understand the issue, please send us the following information:

  1. What is the brand and model of the computer?
  2. When this problem started?
  3. You did it all changes to the computer before this problem?

  I suggest you follow these steps and see if it works:

  Run the System File Checker

  File system check to determine if the problems you encounter on your computer are caused by one or more system files.

  You can read the following Microsoft article to repair corrupted using SFC tool files. Use the System File Checker tool to repair missing or corrupted system files

  Reference: http://support.Microsoft.com/kb/929833/en-us

  Uninstall device drivers

  1. Press the Windows key + R
  2. Type devmgmt.msc
  3. Right-click on each device that is listed under the category unknown
  4. Uninstall each device and restart the computer

  After reboot, Windows will automatically install the device driver, and you should see the device listed in the appropriate category.

  Hope this helps, get back to us if you need further assistance for Windows.

• Laptop HP G60-630US - Webcam peripheral is pop + unknown device unrecognized USB inverter [update]

  My webcam and everything was working fine last night. I even used my webcam on the new yahoo I had installed a few days before. When I got up this morning and turned on my laptop, I kept getting pop ups every 3 minutes indicating unrecognized USB device despite not having that whatever it is plugged. I check the Device Manager and see an unknown device and the lack of imaging devices. When I try to go in youcam, it tells me that the cam is not detected.

  My notebook is HP G60-630US Notebook PC, Windows 7 Home Premium 64 Bit.

  There is no change made last night. Even if after all this I tried to delete all the usb and restart, but nothing has worked. I always get the frequent pop ups. Please any help would be appreciated.

  Update: I just ran the update BIOS and instead of an unknown device, it says USB composite device

  Thanks, I tried. He has not worked for me. I just restored to factory settings, and that solved.

• Under usb Bus. controllers, I would like to remove or uninstall the mouse drivers several at once?

  under usb controllers (in the device management) there are several (5) standard open HCD usb host listed controllers.    How can I remove or uninstall all at once instead of one at a time.  When you uninstall one both this disables the mouse and you cannot use it until you close the machine and then reconnect the optical mouse usb.  Thank you!  Maybe I should not uninstall any of them? LOF all usb ports work fine and do the mouse.

  What makes you think they are controllers double?

  I don't know what computer you have, but that seems pretty normal to me.

  I wouldn't try to uninstall them. As long as the material is present on your system, they will be resettled at the next reboot.

• An "unknown device" in Device Manager.

  Hello, I bought today my new 4330 s ProBook.

  Installed Windows 7 ultimate 64-bit.

  I have an 'unknown device' under 'other devices' which I suspect to be vidality fingerprint sensor.

  However I simply could NOT find a suitable driver (assuming that it is actually FVS)

  The little info has the device is:

  Location: Port_ #0001.Hub_ #0002

  Hardware ID values:

  USB\VID_138A & PID_003C & REV_0086
  USB\VID_138A & PID_003C

  Help, please!

  It is the sensor of validity... a sine qua non for this driver is that you have HP protect Manager security tools already installed before you install the driver of validity. Your drivers are all displayed here:
