The following in the patch looks wrong for me:
----------------------------------------------------------------
+ if (i->bInterfaceClass == 255)
+ {
+ --is_scanner;
----------------------------------------------------------------
because there are USB scanners which have bInterfaceClass = 255
e.g. my Epson all-in-one device, see my other mail where I
listed sane-find-scanner and lsusb results on three hosts:
----------------------------------------------------------------
Bus 002 Device 003: ID 04b8:080f Seiko Epson Corp.
bDeviceClass 0 (Defined at Interface level)
idVendor 0x04b8 Seiko Epson Corp.
idProduct 0x080f
bInterfaceClass 255 Vendor Specific Class
iInterface 5 EPSON Scanner
bInterfaceClass 7 Printer
iInterface 6 USB Printer
bInterfaceClass 8 Mass Storage
iInterface 7 USB Mass Storage
----------------------------------------------------------------
and my plain Epson USB scanner has also bInterfaceClass = 255
----------------------------------------------------------------
Bus 001 Device 002: ID 04b8:0121 Seiko Epson Corp.
bDeviceClass 255 Vendor Specific Class
idVendor 0x04b8 Seiko Epson Corp.
idProduct 0x0121
bInterfaceClass 255 Vendor Specific Class
iInterface 0
----------------------------------------------------------------
