Necro: Re: MMJoy - Build your own USB controller Well, when I reset twice, "USB Serial Device" changes from COM5 to COM6 and stays that way for a few seconds. Then it returns to COM5 but nothing else happens.
It is this exact moment, while on Com6 in your case, ( usually you have 8 seconds) , in MMjoy2 on the Firmware Tab to hit Upload Firmware.
With Device Manager Open it is easy to see when the Port No# changes after the Double Tap on the Reset button .....
