CentOS - Jan 2021 - How to reset the USB subsystem?

Hi,

my USB connected printer goes into deep space from time to time probably
due to a HW problem on the MoBo.

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

Thanks
Frank

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.

Good Luck!

Fred

I am using Debian but the usbutils package has the usbreset
application which works great for me. I had issues with my DVB-C USB
receiver and usbreset did the task quite well.

This one, there is RPM as well:
