[sane-devel] Re: umax astra 1600 usb and sane on FreeBSD 4.6

[Thomas Niedermeier]

Hi,

I did #define NO_AUTODETECT, however it still doesn't work and I get:

scanimage -d umax1220u:/dev/uscanner0

the same is true for sane compiled with libusb and/or the scanner
attached to ugen0.... libusb seems to work basically, however, when the
scanner is attached to ugen0:

      bEndpointAddress: 82h
      bmAttributes:     02h
      wMaxPacketSize:   64
      bInterval:        0
      bRefresh:         0
      bSynchAddress:    0
      bEndpointAddress: 83h
      bmAttributes:     03h
      wMaxPacketSize:   1
      bInterval:        1
      bRefresh:         0
      bSynchAddress:    0

so I guess the backend doesn't work... :-(

I'm just guessing: The backend tries to identify the scanner (vendor
and product) and gets the response that this is not possible (FreeBSD
uscanner driver can't do it). Usually that's no problem but the
umax1220u backend seems to insist on this identification.

There is a line

#ifndef NO_AUTODETECT

in the code (backend/umax1220u-common.c). Try 
#define NO_AUTODETECT
and recompile. Maybe that's enough to get it running.

Probably the maintainer of this backend can tell more details.

You may also try the CVS version of sane-backends which has support for
libusb. This may work (if you have installed libusb).

Otherwise I guess the backend must be changed.

Bye,
  Henning
