[sane-devel] Canon LiDE 110 motor movement problems only on some machines / architectures

I just got a Canon LiDE 110 and am getting different results depending upon
which of my computers I try to scan from.
Here's the results so far:
* HP laptop (Intel Core i3) / Windows 7:
Works correctly. This just establishes that the scanner isn't broken.
* Dell tower (Intel Core 2) / Debian 8 (amd64):
Works correctly (using scanimage).
* Dell mini10v (Intel Atom) / Debian 8 (i386):
Bulb lights up, scanning head moves very slowly and jerkily in the correct
direction, but only travels about 0.5cm by the time scanimage thinks the
scan is done.
* Pogoplug Mobile (arm5tel) / Debian 8 (armel):
Bulb lights up, but scanner head appeared not to move and made grinding
noises. Was it trying to move in the wrong direction? Is that a timing
issue or an architecture endianess issue?
The grinding noises don't appear to be 100% reproducible (sometimes the
head just appears not to be doing anything).
* Raspberry Pi B+ (armv6l) / Raspbian (armhf):
Bulb lights up, scanner makes very brief servo noises, then appears to
remain silent for the duration of the scan. Didn't appear to make grinding
So, I think there is a pretty solid opportunity to solve this because I
have a few working and non-working platforms to work from.
What's the next step here? Getting some form of more verbose output from
the genesys driver?
