I finally managed to get a Pic18F2550 to behave as a USB drive using Microchips USB files. I think it's probably the most useless drive going as it has a capacity of just 4K. Next I'll try and get a serial EEPROM connected up to increase it's capacity.
If anyone is interested I can probably work out what I had to change in order to get it working (it wasn't much). The biggest headache was getting the bootloader to fit in 2k with the student edition of the C18 compiler. Once the compiler times out the code jumps to around 2200 bytes.
