The default ISP speed of the AVRISP mkII as shipped appears to be somewhat random. I've seen parts that are terribly slow as shipped. Maybe yours is just too fast? I'm not sure whether the stk500v2 driver backend (which is also used for the AVRISP mkII) does really honor the -B option. Sure, it should (and if it doesn't, please file a bug report). But then, the AVRISP mkII remembers the last ISP speed that had been configured in its EEPROM, so what you can always do is: avrdude -p m48 -P usb -c avrispmkII -tuF Then, enter "sck 10", a 10 µs SCK period ought to be sufficient for almost any situations (except an AVR running from the 128 kHz RC oscillator), and leave AVRDUDE's terminal mode again. Try to connect again after the AVRISP's ISP frequency has been changed. -- cheers, J"org .-.-. --... ...-- -.. .
