I have a SainSmart Mega and when I connect it to my PC, it recognizes it but only as an "unspecified" device and doesn't give it a COM port (see image) and in device manager it shows up as AT90USB82 (see other image). I went through this process: https://www.arduino.cc/en/Hacking/DFUProgramming8U2 ,…
