windows 10 surface pro 2 through usb with ftdi cdm drivers (microchip to pc / 3d printer drivers) and repetier 2.0 to tronxy p802m 3d printer: keeps coming up with access to the port 'com6' is denied. Com 6 is the port that disappears if I unplug it and reappears if I re-plug. phone connects fine through usb. 3d printer unrecognized by other software as well. however my pc easily recognizes the 3d printer. Any advice / experience appreciated. ty
