I have a Olimex AVR-ISP500 which was purchased from
Dontronics. my device manager indicates that it is working however I can not
connect to a device, I am not looking for waranty as I bought it second
hand. I would like to test it to see if I need to replace it. When
pluged in to the USB the LED is green, should I then read a voltage
between pin 2 and pin 4 on the 10 pin socket. Any other test? thank you
