TRNIE: Transaction Complete Interrupt Enable bit
and see what happens.

WHAT DO YOU MEAN "You don't know?"
Hmmm, I would tend to believe that flag does not distinguish between upload and download transactions; I really need a PC-to-PIC complete flag.
Well, since I have an interrupt controlling user input on the PIC, I can just loop the PC-to-PIC USB routine. This will make things much easier to manage, I'm not very fond of using that all-encompassing USB_INT interrupt.
Now if I can only find out why Windows won't recognize the device, things would be peachy:
