using a mega1280 with ethernet shield, IDE version 1.0 from the ubuntu (12.04) repositories. I'm trying to upload a sketch and get the error (avrdude: stk500_recv(): programmer is not responding), I have the correct board selected under Tools->Board, and under Tools->Serial Port , /dev/ttyUSB0 is selected. Under Tools->Programmer AVRISP mkII is selected. I see that this error message is common, but I'm not seeing solutions. I know that this board works because I tried it out on a friend's (ubuntu 11.10) machine.
I've also run the command
ls -l /dev/ttyUSB*
while the board was connected, which gives me
crw-rw---- 1 root dialout 188, 0 Jun 10 11:43 /dev/ttyUSB0
not really sure how to proceed.
