Hi all, I spent a lot of time last night, unsuccessfully, trying to install a ramps board (the second one I own) onto a computer with no success. My first one installed on the same machine just fine so I was frustrated.

The new ramps shows up in hardware manager as a "rumba atmega 2560 co". The first ramps, and all my other mega 2560s all show up properly as "arduino mega 2560".
I have tried mega 2560.inf files from several different releases of arduino and nothing has worked. The vendor suggested that I try a rumba hardware driver which I haven't had the time to try yet (Will do tonight after work). If it works, I'm concerned about pin outs and inconsistencies between what the controller thinks it is (a rumba) and what it actually is (a ramps 1.4).

Can I reflash the atmega with a new boot loader or something to straighten it out?

Ok, I think I might have this one figured out. I believe I was sent a Taurino Power Mega 2560 instead of a regular Mega 2560. I'll try the drivers tonight.
