I get error when I try to use it, Windows report problem getting ID and trying to force driver doesn't work. When I tried to flash a random sketch to the ATTiny44, I got error it's not responding.
I've already replaced ATTiny44 on it and I can now program it but I am having heck of a time finding the correct firmware to use to make the chip run like ISP once again. My search for USBtinyISP firmware keeps getting me ATTiny2313 even if I mentioned ATTiny44 in the search. And the firmware files I downloaded is a bunch of files, looks like I am supposed to use AVRdude to compile and upload rather than Arduino IDE.
So can anyone tell me which file is the right file for ATTiny44 version of USBtinyISP, and what's the command to set the fuses correctly (12MHz external, etc) and upload firmware? This is what I have:
SJVCC connects or disconnects 5v to ISP header for when the target device has its own power or not, and SJFAB enables reset for reprogramming ATTiny44
