Got my old STK500 powered up, with the MPU that came in the box. Seems to run ok, the program on the mcu lights LEDs when buttons are pressed.
Started AVR studio 5.1, it can't see the device. I checked the device driver install and there's an error "The drivers for this device are not installed. (Code 28)". I re-installed from the installer that came with the cable, then found another installer on Tom's hardware web site, but get same problem.
After some searching, didn't find a solution. Anyone have any tips on getting the usb to serial drivers installed on old XP?
