[sane-devel] General user experience for me with Canon DR 9080C and 7080C

[m. allan noah]

Hmm, I don't recall any such report in the past with those scanners,
but other scanners have problems with Linux kernel USB behavior. Can
you try to run your scanning program with the following environment
variable, and see if the problem persists?

SANE_USB_WORKAROUND=1

If you still have problems, please collect a log file, compress it,
and send it to me, using something like this:

SANE_USB_WORKAROUND=1 SANE_DEBUG_CANON_DR=15 scanimage --resolution=50
> canon.pnm 2>>canon.log
(perhaps running that twice if the first time succeeds)
gzip canon.log
