I'm having trouble having the keypad recognized by my PC. Not sure what's going on? I plugged it in via USB. Not recognized. I connected via Bluetooth and it works, but the software (GK6XPlus Driver V6.0.0.39 at jikedingzhi) does not recognize the device when plugged in. Any tips on how to get the device recognized so I can remap the keys? Thanks! I got this in the December 2020 batch.
