Ok, what about a sleep problem?

Does the PC take a nap and forget to wake up the USB port? Or is your PIC taking a nap and not waking up, or losing important info just as it is being awakened? Maybe the awakening process is taking too long for the USB connection to be maintained properly?

EDIT: What if you shorten the sleep process to a minute? Start with the PC, and then the PIC later if it has a sleep.
