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.
This was answered here, only a couple of days ago.
