<pre>I found another driver already in the kernel tree which is using the report ID
0x5D
for multi-touch support. It is an ElanTech driver:
drivers/input/mouse/elan_i2c_core.c
But the format of the 0x5D report in this driver is slightly different to the
one we're using in the hid-asus-fte-dkms driver. However:
- the first byte of the report; and
- the first three bytes of information for each contact
appears to be the consistent across all three devices (defining just the x and
y locations).
As Benjamin has pointed out - it looks like your driver supports 4 contacts and
each contact uses just the first three bytes of information for each contact.</pre>
