I purchased an ASSEMBLED USBTinyISP programmer and plugged it in to a USB port on my computer having first downloaded and installed its drivers. The green LED remains off.
The only clue I get is a message which says "enumeration error". I simply do not know what that means or what I have to do to fix the problem. And yes, the USB cable is OK
-- it works fine with an Arduino UNO R3, which shows up in device manager under Ports. No such showing in Device Manager for the Tiny ISP programmer!
Anybody else had this problem and managed to get a solution?
Thanks in anticipation,
