Don’t try this at home…
I got a good suggestion in a comment to try and unload/reload the USB drivers to attempt to resolve my camera issue (previous post). However, I forgot that I’m also using a USB Keyboard and USB Mouse. When I unloaded the USB Drivers - well, you get the picture… The comment recommended I do it like this:
sudo rmmod uhci_hcd; sudo modprobe uhci_hcd
However, I just ran the first command which removed all USB support. Being that I couldn’t direct any further input to my computer via mouse/keyboard I ended up having to reboot. Next time it comes up I’ll enter it as one command which will hopefully work to resolve my camera issue.

How about: “sudo rmmod uhci_hcd && sudo modprobe uhci_hcd”
I’m still using PS/2 mouse and keyboard and will continue to do so as long as these are supported.
