Implementing a USB master is extremely complicated, and probably not
something that could be done purely with a PIC I suspect (search in the
archives, this has been discussed a few times before).  Your life would be
*much* simpler if you ignored the USB drives and used one of the flash
memory cards e.g. compact flash, smartmedia, MMC.  Many of the MMC cards
have an SPI mode to make interfacing with a micro easier.
