Hi,

Elantech touchpad doesn't work on Fujitsu E556 laptop.

Touchpad doesn't move the cursor at all, and it seems to disturb 
keyboard too. If I accidentally hit the touchpad while typing, the key 
gets "stuck" (it keeps repeating until I press something else).

Fortunately, the touchpad works fine when I force crc_enabled on with:
echo 1 > /sys/devices/platform/i8042/serio2/crc_enabled

or by applying the following patch, but replacing the U745 with E556:

Best regards,
