okay, lets try this.

1. With the mouse connected collect the output of usbdevs -v. That should
show how the mouse is connected.

2. From the trace it looks like the mouse is USB2 since ehci keeps popping
up. Try removing ehci from your kernel.

Your mouse gets upset after we attach it, which is what this is all
about:
uhci_idone: error, addr=2, endpt=0x81, status 0x500000<BABBLE,STALLED>

STALLED is an error in USB terms.  Exactly why the device is stalling,
though, is unclear.

Try #2 above and see if it works any better for you.
