uscanner has never supported attaching to other than the first
interface on the device. This is hardcoded in USB_ATTACH(uscanner)
and is not changed by my patch.

Do you have a plain scanner or a multi function device?
(What is the product number or output of  usbdevs -av?)
Did the device work without my patch?

If your scanner previosly worked, the only reason I can think of is
that your scanner needs  usbd_set_config_no. If this is widespread
for pure scanner devices, I may rework the patch to be able to attach
to both devices and interfaces and use usbd_set_config_no if it did
grab the entire device.  The concept of set_config_no breaks all multi
function devices.
