Hello Gabriel,

I'm almost a 100% sure this is not a defective drum pad. People even 
wrote software (or attempted to) for it to make it work with Linux:

I agree that the hid device looks refurbished and I now also noticed the 
hid device has the resistor R1 while the midi device lacks this resistor.

I'll also test with Windows this week and report back.
