The PICusb code and the pendrive are both slave applications.The pic would have to have master code written for it to talk to the pen drive. A PC has the master code for usb but as with all PC stuff it is bloated so the task of duplicating it in a compact form is formidable. A single slave device specific master probably could be written but it is not for the faint hearted.

The simplest route to this, is the FTDI Vinculum chip, in it's 'demo' VDRIVE board, which implements a serial or SPI interface, able to talk to such a drive.
