>Description:
Without the following modification to sys/dev/usb/uscanner.c,
the USB driver correctly locates my USB scanner and
displays it's product ID string at boot time, but I
can't talk to it like a scanner, with xsane (for
example).
>How-To-Repeat:
Plug in AGFA Snapscan e20 into USB port
re-boot system
observe log messages
observe failure of scanner software to find device
>Fix:
Apply the following patch to
/usr/src/sys/dev/usb/uscanner.c:
--- uscanner.c.orig Mon Oct 15 14:44:06 2001
+++ uscanner.c Mon Oct 15 14:43:13 2001

I use a /usr/local/etc/sane.d/snapscan.config file that
looks like:
usb /dev/uscanner0
firmware /usr/local/share/sane/snape20.bin
Snape20.bin is a file from the DRIVERS directory on the
Agfa "ScanWise" CD that came with the scanner.
Both xsane and xscanimage now work, with the device set
to snapscan:/dev/uscanner0.
Oddly, the appropriate patch to usbdevs was committed
some considerable time ago, along with a whole bunch of
other AGFA scanner model IDs, but I can't test those, so
they're not part of this report.
Thanks to the authors of the uscanner driver: it works
beautifully most of the time. (The scanner software
wedges if the scanner takes too long to warm up, but
killing and restarting seems to fix that. I don't have
anything concrete enough to base a PR on for that...)
