Is there a way how to reset the USB subsystem the same way one can restart networking or X without the necessity to reboot? Couple of cable ideas that may be of interest. I got all of these from Amazon. In my new car there is only one usb port to connect data deviced to. When I used my micro thumb drive to play music the car often "lost" the drive and it had to be pulled and reinserted. Not easy with the micro drives. A second problem was using the one port for music source or plugging in my phone for Android Auto. The cars usb system would not deal with a hub of any sort. Thus the nice credit card sized 4 port hub with individual on/off buttons for each port did not work. The lost thumb drive was solved with a cable having an on/off switch. Think of it as a 15 inch usb extension cable (M -> F) with a switch in the middle. Both problems were solved with a USB printer A/B switch. This is not a hub, but a switch intended to let you print to either of 2 different printers from a computer having a single USB port. In my case the music thumb drive and the phone are the "printers". Jon -- Jon H. LaBadie j...@labadie.us ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

from a non-expert (me): possibly figure out what happens when the device is plugged/unplugged and doing that by hand. if you can find the udev file(s) that manage the port(s) that get hung you may be able to figure out what those steps would be. or you could try, when hung, plugging it into a different USB port... some motherboards have multiple USB controllers, so even if one gets wedged tight, the other one(s) shouldn't be.

Is there a way how to reset the USB subsystem the same way one can restart networking or X without the necessity to reboot?
