Yep. Matt has right. 1.The clock speed is esential. 2. You will notice quite a long delay (5s or so) between plugging the pic usb and the moment when OS recognize it on pc. This depends by your computer speed and pic firmware contents. If pic clk is wrong, you will not see any usb device. After it appears, check on printer/pheripheral for your device but watch for any warnings there....
