Re: Reset USB after printer reattach?

Hello,

I occasionally turn my USB printer off and on again, after which it
doesn't reattach to ulpt0 or show up in dmesg, same thing if I
physically remove and reattach the USB cable. Rebooting fixes it, but
I'd preferably not do that each time I reattach USB devices.

Host machine is a Raspberry Pi running

Printer is a Samsung CLX 3185.

Any ideas how to force-reset USB?

Have you tried

        drvctl -s <parent device>

??
