KVM switch w/ usb i/o for keyboard mouse doesn't work [Solved]

Edit:

This problem appears to have magically disapeared. I'm still not sure why it happened or why it has ceased.

Hello Everybody,

I'm not sure why this is happening, but I've got a KVM switch that used to get "automagically" detected as "a no-brand KVM switch" on boot-up that has ceased working. I don't get this "no brand KVM switch" detected on boot-up anymore, but I can use the VGA part of the switch, at least, however the keyboard and mouse don't work unless plugged directly into the computer.

Below I've attached the result of

dmesg | grep --context=3 usb

dmesg | grep kvm

returns no result.

The most signifcant thing seems to be:

usb 1-2: new full speed USB device using uhci_hcd and address 7
usb 1-2: device descriptor read/64, error -71
usb 1-2: device descriptor read/64, error -71
usb 1-2: new full speed USB device using uhci_hcd and address 8
usb 1-2: device descriptor read/64, error -71

usb 1-2: new full speed USB device using uhci_hcd and address 10
usb 1-2: device not accepting address 10, error -71
hub 1-0:1.0: unable to enumerate USB device on port 2

I've googled this, and somewhere it was suggested this mean the usb device is not drawing power. The only thing that has happened that I can imagine as being the culprit between function/dysfunction here is that there was a power outage (circuit breaker tripped), and though my computers were on battery-backup, the monitor is not. I don't suppose that this could have messed up the switch?

Note this problem is uniform across 3 computers, 2 which have recently run a system update, but the 3rd has not recently run an update, this is not an Xorg problem, "K and M" don't work in either console or X.

Any help would be appreciated. Below as, mentioned previously, is the output of

dmesg | grep --context=3 usb

included on the off-chance that someone sees something significant there.
