@rey if only I could get something​ to cut the power to my usb devices. Sometimes the mircocontroller crashes on my rudder pedals and even switching on/off the computer doesn't fix it.
@rey I could build something that cuts power if it doesn't detect the USB start of frame signal. hmmm
@geekylou oh no, haha... that sucks
Put a normally-closed pushbutton in line with the +5V supply? Or, one of my USB hubs cuts power for a few moments when the computer comes/goes/reboots... hmm
