Hi
i have a sparkfun attiny85 board. i installed its drivers and program it with arduino and use digiusb and everything work well. then i replace attiny85 with attiny45 in the board. but in this case drivers dos not recognize by computer and an "unknown device" appears in device manager...
according to similar structure of both microcontrollers (attiny85 and attiny45) why this problem happens?
please help me to solve it.
thank you...
