I've been using the avr-mkII programmer to program the arduino through ISP for the past month. Recently I noticed that ever since doing that I lost the ability to program the arduino through the USB port - Serial 0. Does anyone have a clue as to how to reset the boards back to normal? I tried this with a few different boards and it is all the same. The New boards that haven't been programmed through the ISP act normally. I basically have lost the ability to communicate with the usb programmer chip. Has anyone experienced this before? Would I need to program the usb communication chip through it's ISP pins? Here the typical generic response that I get when I try to program them.
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
Thanks in advance.
