 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.
