Re: input: elantech.c: adding more Fujtisu notebooks to force crc_enabled

[Rainer Koenig <Rainer.Koenig@ts.fujitsu.com>]

Dear Sam,

unfortunately I'm on sick leave this week so far away from my lab and
with no access to the system. What data do you need?
On request of Ulrik I had a look at the firmware and capabilities and
posted another "patch" last week, maybe this already answers your question.


+ * Fujitsu LIFEBOOK E544   0x470f00        d0, 12, 09      2 hw buttons
+ * Fujitsu LIFEBOOK E554   0x570f01        40, 14, 0c      2 hw buttons

If this doesn't help then please be patient until next week when I'm
back in the lab.

Regards
Rainer
