Unknown USB Device connected?

Im using the MQX USB Device library with a 52259. With most Windows computers, it enumerates correctly and Windows recognizes it as a CDC device and it works. However, on some computers, Windows reports "Unknown USB Device connected", and there is nothing I can do to get it to enumerate or work at all.

This happens on WinXP, Win2000, and Win7 computers. Some work, some dont.

Ive tried upgrading from MQX 3.6 to MQX 3.8 to no avail.

Has anyone else seen this and figured out how to fix it?

Thanks for your help,

Byra
