UHID problems:

Prenote: Using FreeBSD 5.3-BETA2, cvsuped source current as of a few
hours ago (Sat. Aug 27th-ish)

I'm seeing a lot of these kind of issues so I feel like adding to the
noise. :P This really wouldn't bother me so much if my mouse wasn't a
USB device. Luckly my 5.2.1 kernel still works and doesn't seem to show
any problems with a 5.3-BETA2 userland.

The input storm happens when usbd is called. usbd promptly fails because
the device stalled, or some such.

I pray that this is my ignorance over something, because that means one
of you will be able to beat me over the head with a solution. If not,
well, I will aid in fixing this problem in anyway that I can.
