is a pretty good page about PIC USB devices.

You wont get 921 Kbit throughput out of the USB interface because it 
transmits only 1 byte transactions in the direction PC to PIC.
And the PIC uses quite many instructions per transaction.
It is set up like this to make the implementation of KEY and RXU as 
simple as possible.
But at least you will get the 921 kbit interface speed.
