• M400 - Bluetooth is only recognized as a unknown usb device

  Hello!

  I have a problem with the bluetooth driver / stack. I just got my new M400 and the first time I have activated Bluetooth, battery Setup came - but Windows just said when Setup tried to install the driver that an error has occurred - nothing more.

  The Bluetooth ACPI works very well according to the Device Manager, but that's all. There are no other Bluetooth device list - but an unknown USB device. I compared the device with the id id in the inf file (which is located in the folder of installation of battery). This device is supposed to be the Bluetooth USB Controller-5 of TOSHIBA (USB\VID_0930 & PID_0508) but Windows does not recognize the device - and it is correctly listed in the inf file. Even if I try manually installing the Windows device requires just that the inf file contains no information about the device (which is not true).

  Any ideas what I can do? I already uninstalled the battery and installed the new version of the stack, but it makes no difference.

  Concerning

  Alexander

  I have it solved by myself. There is a defect in the file INF from Toshiba. From the beginning, it lists only Chicago as a compatible Windows version and windows compatibility control is a.

  If you change the string from Chicago to Signature = ' $Windows NT$ ' and out of the chain of compatibility that it all works very well. Unpack the battery Bluetooth to a folder, so just go to 2KXP/Windows/Inf and edit the inf file, then run the setup.exe in the folder 2KXP.

  Hi waly,.

  Thank you for the information. I suggest that you unplug all USB connections and refresh your laptop. Then try to use your webcam. I think that the problem with the USB connection that gives you the error and not your webcam. Here is a document on how to update your PC to solve problems (Windows 8).

  If you are still experiencing a problem with the webcam and then one of the documents in the previous post should help now. Any stage of document Windows 8 will be the same for Windows 8.1.

  I'm also including this document how trouble Code 43 errors that will help determine which USB product causes the error to appear.

  I hope that this information help, please let me know how it goes.

  Good luck and have a great day!

• Satellite L500 - 19 X - Webcam listed as unknown USB device

  I had problems with my camera is not visible to the software Toshiba or Skype. Restart resolves the problem, but he then disappears again after a while.

  I downloaded the software for the Webcam from the Toshiba support Web page and reinstalled successfully, but now the webcam disappeared completely from the list of devices and shows simply Manager as unknown USB device.

  How can I get it back?

  Hey,.

  Important if you use the webcam: you can use it with one program! That means don't use Skype and webcam software at the same time. For example, if you use it for Skype, close the software of the webcam.

  If the webcam is shown as unknown device, you must reinstall the driver for the webcam I think.
  To control first the software list in Control Panel and remove Camera Assistant Software. After that, you should restart the computer and then reinstall the new software of the webcam.

• Code 43 unknown usb device

  I use a laptop HP G20 Windows 7 SP1. Shortly after one of the HP software update, I started getting errors indicating an unknown USB device. I unplugged all USB devices, but the error message still appears. I reinstalled the Realtek USB 2.0 card driver, but the re - install failed. I removed the device to uninstall programs and installed the latest device driver, but it did not help. I noticed that even after I uninstalled the device I was still getting the error message. My USB mouse does not work, but my sony camera works. I am strongly suspect a hardware failure, but I can't find a job anywhere hardware diagnostics.  Please someone help!

  Its some sort of hardware problem, chipsets are not replaceable, only card mother together.

• Satellite M30X-129 loses connectivity with the external USB device

  I have a problem with my laptop that has regularly been do worse and I can handle is no longer!

  Whenever I work with external devices via USB ports (all kinds of devices but my external hard drive Smartdisk CrossFire and my iPod in particular), after a certain period of time (sometimes minutes, sometimes hours) the laptop loses connectivity with the device.

  If happens to be listening to the music, download photos from a camera or laptop computer for the ' net or sync of the iPod, the connection is cut off, turning off the device and I have to start all over again!

  I'm almost at the point of launch of the laptop by the window, so any help is most welcome.
  Thank you

  Hello

  This happens also with the external USB mouse?
  This occurs if the power adapter is plugged or only if the laptop running on battery?

  In-hubs properties > Device Manager USB root-> power management
  You will find the option called allow the computer to turn off this device to save power.

  I would recommend the brand and disable this option.

  Maybe it helps.

  By the way; When do you update the operating system? I think that it s there long time, perhaps some system files or registry entries are corrupted or a 3rd party application affect the USB functionality?
