Hey, have a look into using something like a nslu2, it s a small ARM based
linux computer, but they contain USB-host hardware and have been linked to
cameras in the past for similar projects.

There is no PIC with USB host capability.  There are ARM7's that can act
as USB host devices.  There is at least one (and maybe more)
pre-programmed ARM7 that claims to be a USB host bridge chip (USB to
UART/I2C/SPI, etc).  And of course there are the full blown USB host
chip sets.

You might be able to function with USB-TO-GO and that might be somewhat
simpler than a full blown host.
