[PATCH] USB: Support for Posiflex PP-7000 retail printer in Linux

This little patch adds recognition of Posiflex PP-7000 retail printer to
ftdo_sio module. The printer uses FT232BM bridge programmed with custom
VID/PID.  The patch posted to lkml and sf.net was for 2.6.11.1 kernel,
here is one reworked for 2.6.12.
