Camera model
Logitech C920
Printer model
Prusa Mk3s+
What is the problem?
Logitech C920 and the Prusa Mk3s+does not show up in linux on my PI 3B+.
They both worked a day ago but only in one port. Now it does not work in any port.
What did you already try to solve it?
I have verified that the webcam works on my Windows PC.
I have verified that lsusb does not report the webcam.
I have tried every port on the PI.
I have restarted between each USB port change.
I have tried leaving the USB plugged in during reboots and leaving it out then plugging in once booted. No Dice.
