Most USB devices only have one configuration. You could
try commenting out the call to usbd_set_config_no() and
the related error checking code in the attach routine of
uscanner.

If that doesn't work or you want to investigate further,
adding:

options  USB_DEBUG

to your kernel configuration file will give you some
more useful debugging messages. You can control the
verbosity level with the hw.usb.debug sysctl.
