Make, model, story "It worked until I installed this CD emulator" and such.
Windows can do this but my suspect is drivers such as motherboard drivers NOT USB drivers and apps.
I have been trying to solve a problem with my USB thumb drive. In Win 7 pro, I am unable to see any USB thumb drives in My Computer or Disk Manager. My USB mouse works fine. In Device Manager, I can see the drive but it has a yellow exclamation mark. In Properties, the system says Error Code 38. I have tried uninstalling and reinstalling the driver and all of the USB port drivers to no avail. I am able to get the USB driver to work in Safe Mode. I have also tried cleaning the registry without success. I have tried using Windows native troubleshooter - no help. Using MSCONFIG, I rebooted without any Startup programs or Services and in Diagnostic Mode - the problem still persists. Before I spend a day reinstalling Windows and all my software, I wanted to see if anyone could suggest a solution I have not considered. Thanks.
