Arduino Mega 2560avrdude: stk500v2_command(): unknown status 0x01
avrdude: stk500v2_disable(): failed to leave programming mode
Windows 7
Board selected to 2560
Only one COM Port is listed: COM 3
I have tried plugging the USB into all 3 USB ports on my laptop. No change.
also tried downloading the software again and unpacking it. No difference.
With a regular Arduino Duomilanove Atmega 328 it works fine and Windows 7 installs a driver for it automatically, but is unable to do so with the Arduino Mega.
opening device maneger and telling windows to look for driver in the driver folder with the software returns no results either.
the LED next to PWM 13 is off
