(Link in compliance mode) unknown USB device
Hello, when I start Windows 8 Pro I have error "USB device not recognized" and then when I check the Device Manager it is peripheral USB unknown (link in compliance mode), but I have only the mouse and keyboard connected to usb and they work very well. When I try to update the drivers for this unknown device, I get "the best driver for your device software is already installed. When I run troubleshooting I get "Device unknown USB (link in compliance mode) does not work properly" I know already and its not that useful.
Thank you.
Hello
2. What is the number of brands and models of mouse and keyboard?
I suggest you try to plug in another mouse and keyboard on this computer and check. This is to check if the problem is with the computer or the keyboard and pouts.
You can also download and install the latest drivers for the chipset and USB controllers on the manufacturer's Web site. And check if the problem persists.

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. -
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.

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!

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.

Interfacing with several unknown USB devices; all producing NMEA strings
Hi all
Question about the peripheral USB interface and their associated drivers.
I have the obligation to build an application that interacts with the USB devices that produce NMEA strings. I have the library to parse NMEA strings, but I fight with interfacing with several unknown USB devices. When deploying applications, I know not all possible USB devices to use.
Is it possible to produce one driver who will accept any USB device strings?
Or, more likely, is there a way to get the LV to recognize a connected USB device and automatically find / install the driver like windows does and is it possible to do in a deployed application?
I had a trawl of the forums, but I've not found anything that specific.
Thanks, I really appreciate the help.
About the VI "set up the serial port", my problem is that the choice of COM port is in a separate menu (not directly related to the VI) and it allows all possible COM ports to be selected. That can be addressed.
I am not expecting an all-in-one solution but asked the question in case it was possible.
What I realized, is that for my specific condition to read strings from a USB device. It is likely to be sent over a serial connection. LV can handle this well and easily assuming the device has the installed driver / settings are available.
LV (and indeed any other program) will not work without a device driver / settings. In this case, parameters set must be found (error) / a USB RAW driver would need to be developed. Devices requirng a RAW USB driver would need a serious review to continue due to the time and effort required. All this effort is work inherited from the AIDS to navigation
I appreciate any help and I think I got the answer I was looking for! Thank you very much

I tried:
Re-install HP MediaSmart Webcam, restart
Re-install the Firmware of HP Webcam, restart
Still havving the same question, the stay of device in the 'unknown' State in the Device Manager and the Firmware still refuses to install - I still have the same error.
I've seen a few post here referring to questions similar to mine, but whenever they were closed and redirected to the post on «purple webcam pictures» I saw no solution to the problem.
Help, please!

If this does not work. Go to BIOS and set the to the default values by pressing F9 and check... If it does not work... we don't have webcam on-site...

C870-14 t and Win7 - undetected webcam - USB device unknown satellite
Hello
Since then, the webcam on my wife's cell phone is no longer in effect.
I checked the Device Manager and I have a unknown USB device. so I downloaded the drivers on the Toshiba site.
After installation, the web cam HD made its appearance in the Imaging section.
When I run the software Toshiba "application web camera" she lights the camera then the blackout.I check back up Device Manager, USB unknown device is in the list and "HD Caméra" disappear...
Of course, I would avoid the reinstallation
It is not easy to say what the problem is here especially if the cam is detected by the system, again and again. It seems that the system can detect the device connected, but it is confusing to me why preinstalled driver works correctly.
At first try please enter the BIOS settings and check if there is option for webcam. If yes do not forget it is activated correctly.
Try to please repeat the action with the installation of the driver just to see if the same thing will happen again.
In the case where this webcam is properly recognized again try to test it with another application like Skype webcam. The same thing happens again? -
