I would use mcproxy3 but cgminer doesn't recognize my bfl jally. Any suggestions?
you need proper driver for butterflylabs sha256 usb device.. I do not remember correctly, but Install drivers from BFL support page, and try, if that does not help, use zadig to change driver to WinUSB one of those combinations should work.
To use bfl on cfgminer u must install WINUSB driver and remove old FTDI driver.
