Could be. The site for the driver said it had been merged into sane, but
not into which version.

I missed something in reading the original mail. The fault occurs in the
FreeBSD driver code, and prevents the creation of a uscanner device.

Maybe the device is USB 2.0 only and needs the ehci driver? Otherwise
building a kernel with 'options USB_DEBUG' might give a clearer picture
of what's happening.
