USB interface

[Frozen001]

Can I use PicBasic Pro to connect a PIC mico to a PC using only the USB port for communications rather than a serial port, eliminating the need for a usb-RS-232 adaptor.

You can. The PIC18F13K50 and PIC18F2455 are two example chips with built in USB drivers.
It takes a little work configuring everything up to use the USB but very rewarding and a lot of possibilities when you get it going.
