Hi
Here is a very dummy patch to make at least my scanning work in 2.5.41.
Obviously registering return scn_minor starting from SCN_BASE_MNR (=48):
retval = usb_register_dev(&usb_scanner_fops, SCN_BASE_MNR, 1, &scn_minor);
But later scn_minor is used to index p_scn_table[], which is only SCN_MAX_MNR
(=16) of size.
Rest of the function probe_scanner() seems to rely on scn_minor starting from 0,
so I just subtracted SCN_MAX_MNR from it.
It makes my Epson 1240U work for me in both USB2.0 (NEC) and USB1.1 (AMD OCHI).
I dont know if it works with CONFIG_USB_DYNAMIC_MINORS oe even with devfs, as I
am not using those currently.
