not an idea, but comments:
The usb problem is huger than thought (not limited to interrupt handling)
It seems that the ugen <-> UPS connection is lost somewhere, and can't
be reattached ("Device does not match - skipping").

When in the above situation, does relaunching newhidups / usbhid-ups
solves the point (=> does the driver start and run fine?)

It seems freebsd has got some more work to be done on the USB stack...
