Well it was hashing on cgminer and lost connection and now the bitforce sha256 sc usb driver wont work with anything, ive put the FTDIChip CDM Drivers back on and I am back to bfgminer or bitminter... So what I have to find out if the FTDIChip drivers work or not after the flash , basically Im stuck using the usb serial port driver (com3)....? 
cgminer doesn't use the FTDI driver - it uses direct USB via the WinUSB driver in windows (... Zadig ...)If it worked before and doesn't work now, then the WinUSB driver was probably screwed up (as can happen on windows with any driver)
Zadig also allows you to re-install the driver.
