Well, I don't know exactly how fast I need it the USART to go. All I know is that it has to be fast enough so that I can transfer 2 bytes from the 16F to the 18F without losing the USB connection.

I had some difficulty in coming up with a baud rate that was compatible between a 16F @ 20MHz and a 18F @ 48MHz. Since I can't change the FOSC for the 18F because of USB, I did the next best thing and adjusted the FOSC on the 16F. I used 16 MHz which is a multiple of 48, I figured I could come up with a compatible SPBRG value that way.

Sure enough, SPBRG=0 @ 16 MHz and SPBRG=2 @ 48 MHz both give 1000 KBAUD. It's not the maximum of 1250, but it's close. Now I have to make some tests later and see if the USB connection holds up.
