usb drives don't mount anymore

[Jack Bowling]

Hello, Matias. This is certainly a shot in the dark. I notice that you
have both the uchi_hcd and ehci_hcd modules loaded. Contention between
these two usb modules has been implicated in some scanners not working.
Try to unload them one at a time to see if things start working:

sudo modprobe -r uhci_hcd

Test to see if things work. If they don't, then try

sudo modprobe uhci_hcd
sudo modrobe -r ehci_hcd

And then test again. Let us know how it goes.

Jack
