for sure, but CDC is th way to be recognise by PC. I use USB WITH CDC protocol.

USB or USB CDC it doesn't change the way to code a USB com in PBP.

For example : when you're waiting for a byte from the PC , you will use "USBin" command. The PC will send you a byte thru his virtual com port but for you it will come in PIC as a standart USB communication.


So logicaly it will be possible to try to detect this activity... but i don't know how
