hello
I have downloaded the TB3 black firmware R1_1_108 and the ardruino program too. everything sets up pretty good. I choose tools>board> mega2560 and then tools>serial port> and the only option was COM78, so I clicked that. then the checkmark circle and everything was fine. then the arrow to install the firmware on the TB3. it says installing..but never completes. if I reset it it says com78 in use. but I cant get the process to complete. any ideas?
thanks
