wardog has probably given you the best advice, but another check you could do is this.

Run msinfo32.exe, which will display a large window of information. Click on the Components entry to open all its sub-entries.

Multiple things you can check, such as Problem Devices, and the USB entry, to see if the Etron USB chip is even listed.

Under the Hardware Resources entry, you could check everything but Memory for clues to the problem.

Have you ever checked the Windows Event or Error logs for clues about this problem?
