PICDEM FS USB is a demo board from Microchip and it
has many examples with different PID.  is one
of the example for the Demo mode.

libusb works very well for the Demo mode (PID=0x000c)
and the boot mode (PID=0x000b).

More info of the libusb based application:

Just wondering if there is any benefit of using ldusb compared
to libusb. Sorry I do not know much about ldusb.

Will the ldusb driver affect the existing libusb based application?

Regards,
Xiaofan
