• 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 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.

  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!

• 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

• (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 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.

• (Redirected) M3800 wakes up only to suspend if the USB device is inserted into the USB port, if not restarts.

  My laptop (M3800) sleep (S3 mode "suspend to ram") ok?

  But he only wakes up correctly if the sleep + curriculum vitae is performed so that a USB port (key, mouse, etc. on sector). If this isn't the case, it simply performs a normal start, so lose the session.

  BIOS version: A09. I had to activate "USB wake support" to allow the computer light up when being opened. Otherwise, it would just stay off and require a hard restart (by pressing the power button for 10 seconds).

  I've been digging on this subject for a while and found no answers. Any help will be appreciated!

• Envy 15-1030 | Webcam is an unknown usb device

  Hello world

  I have one from my webcam on my envy 15-1030ef.

  It seems to be unknown in the Device Manager - I guess that's the webcam.

  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!

  

  

  
  -----------------------------------------
  Envy 15-1030ef | I7 Q720 - 4 GB RAM - ATI HD 4830 - 320 GB HDD

  OK, right click on the unknown device, click software update of the driver and that it points to C:\Windows\system 32\drivers\usbvideo. sys and see if it takes place... 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... While that bit of luck, the recovery may solve the problem...
