That command always experiences a timeout error, but still seems to dump 
something out. Is this timeout error an issue? I'm a little hesitant to 
modify the COMMSCONFIG settings until I know load/save are really working.

root@...alhost:~/obp-utils# ./mxt-app -d i2c-dev:1-004b --save 
~/mxt-save-no-movement.xml
Version:1.16-65-g0a4c
Registered i2c-dev adapter:1 address:0x4b
Opening config file /root/mxt-save-no-movement.xml...
REPORTALL command issued
Timeout

I've uploaded 2 logs to:

http://avon.wwwdotorg.org/downloads/mxt-logs/
(note there's no directory indexing, so manually add the filenames below 
to the URL)

mxt-save-no-movement.xml

This is with the whole series applied. Neither mouse movement nor clicks 
works. I tried mxt-app --reset and it made no difference to the dump 
results.

mxt-save-move-ok-no-clicking.xml

This is with "Input: atmel_mxt_ts - use deep sleep mode when stopped" 
reverted; mouse movement works, but clicking doesn't.
