I have two AVRISPmkII. Currently I'm using a Mega8515 on a AVR-P40B-8515 PCB by Olimex. When switching between AVRISPmkII the second programmer USB address in not reconized. I remember there is a trick to getting a computer to recognize the new USP address but is suppose old age is setting in and ... Anyway what is the little trick?
For give those that have trespassed against me, I can't even remember there names or what they done. Getting old is not for wimps!
