    Cool mouse demo program PIC18F4550

    USBMOUSE.BAS isn't working with my PIC18F4550.

    I had it working without incident on a PIC16C675, so I'm not sure what I have wrong now.

    The only differnce is that I have a 20MHz crystal on the OSC pins, instead of 6MHz.

    I have a 1.5K resistor from VUSB to D- and GND.

    The descriptor file is set correctly, and I have UCFG_VAL set for low-speed USB.

    Now, I did notice that the demo code has a "DEFINE OSC 48" in it, but I'm using a 20MHz crystal, which the text file said is what th edemo programs are set for.

    Any ideas on what could be wrong?

    I've uploaded my config settings
