Windows – USB device not recognised on Windows 7

hp-elitebooktroubleshootingusbwindows 7

I have an extremely strange issue.

Up until 3 weeks my Intermec device functioned perfectly on my HP Elitebook Windows 7 machine. Then for some reason I started getting "USB Device Not Recognised" message. I went through the normal troubleshooting

  • Uninstall USB Hub and let everything re-install
  • Re-install drivers
  • Tried different ports

I then got hold of another colleagues device (exactly the same device) plugged it in and it worked fine. I tried my device on his laptop (exact same spec/make and OS) and it worked absolutely fine.

I then replaced my motherboard on the laptop to see if there was some issue with the USB ports however it still shows the same issue.

I suspect it is perhaps a corrupt registry entry somewhere as I have replaced all the USB inf files in case they were corrupted and still the same issue.

Has anyone had similar USB problems? If so how did you solve them?

I would do three things:

  1. A System Restore to at least 3 weeks back, before the problem started.
  2. sfc /scannow from an elevated command prompt
  3. chkdsk /f from an elevated command prompt at least twice
