Ok.
It does look like there's a problem with one of the USB host
controllers. Does the dmesg log show anything when the mouse and

Here is the kernel log:

At this point its still hung.
What does /sys/kernel/debug/usb/devices contain? (You'll probably have

Rebooting and will paste this. Ok, rebooted, here is the output:
