USB device (webcam) can suddenly no longer be detected

[DBK]

Running Armbian 23.02.0-trunk Bullseye on Allwinner H6 tv box.

Everything has been running perfectly, and both usb ports has been working.

Suddenly the attached usb webcam can no longer be detected (not showing up in "lsusb").

Tried to unplug it and plug it in again, without any change.

Everything is updated, so now sure how to proceed.

Any ideas?

Can I somehow restart the usb controller/service?
