Windows 8, i5, 12meg ram, 100% clean machine (two weeks old, dedicated to Arduino)
First, I have successfully (lucky me) ran an Uno from the same machine two days ago - so this is all about the Mega driver, I think.
Non-specific error on device status in Com Port Display:
This device cannot start (Code 10)
The specified request is not a valid operation for the target device.
Plugging it in: tx light by mini-usb flashes and then green power stays on.
Here is what I have tried:
Installed, selected Mega Board, checked Com ports.
Changed the cable (just in case)
Changed the USB port (just in case)
Disabling, removing device driver, picking up new one on install new device.
Changing com ports. 5 was assigned, I rebooted, nothing, tried reinstalling to 1, nothing.
All while rebooting - each time.
So, is it the Mega R3 Plus or a the device driver. I know windows is a factor but when is it not?
