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.
