title: FTDI Change PID to default
body: <p>I tried to change PID in the FTDI chip (R232R) through FT_Prog. It was working but after it I found that Windows 7 automaticaly reinstal the drivers for USB device, not FTDI device. So I want to change back PID to default (6001). The problem is that I can not see this device in FT_Prog app because it has different PID number. I also tried MProg but with same result. I also tried reinstal Windows FTDI drivers manualy, but still can not see FTD device in FT_Prog. 
  I actualy do not get it why is possible to change PID, if you cut of the communication with FT_Prod.</p>
