I have more details. I added this:
info("probe_scanner: have_bulk_in=%u have_bulk_out=%u have_intr=%u",
have_bulk_in,have_bulk_out,have_intr);
info("probe_scanner: ep_cnt=%u
endpoint={len=%u,dtype=%02x,ep_addr=%02x,attr=%02x,packsize=%04x,interv=%02x}",
ep_cnt,endpoint[ep_cnt].bLength, endpoint[ep_cnt].bDescriptorType,
endpoint[ep_cnt].bEndpointAddress, endpoint[ep_cnt].bmAttributes,
endpoint[ep_cnt].wMaxPacketSize, endpoint[ep_cnt].bInterval);
just before
info("probe_scanner: Undetected endpoint -- consult
Documentation/usb/scanner.txt.");
and now I see that when I insmod scanner.o:
Nov 10 12:06:58 muscat kernel: drivers/usb/image/scanner.c: probe_scanner:
have_bulk_in=1 have_bulk_out=0 have_intr=0Nov 10 12:06:58 muscat kernel:
