[PATCH] support for Posiflex PP-7000 retail printer for ftdi_sio driver

[Pavel Fedin <sonic_amiga@rambler.ru>]

 This little patch adds an ability to recognize Posiflex PP-7000 retail printer for ftdi_sio 
driver. The printer uses FT232BM USB-serial brigde but is programmed with custom VID and PID.
 The patch is made for 2.6.11.1 kernel but is extremely easy to adapt to newer versions. I also 
posted it to "Patches" page on sf.net project. I wrote to project admin a letter asking to give me 
an access to their CVS but got no reply.

 Kind regards
