A couple of questions: 1. Are you sure the port on the PC supports USB 2.0? 2. Which application are you using to test with? 3. Are you doing anything with suspend/resume on the PC? 4. Are you plugged directly into the USB port, or are you using any sort of USB extension cable? Once I know the answers to the above questions, I will see what I can figure out.
