[maemo-developers] [maemo-developers] Touch Screen / Mouse Input

[From: Gareth Bailey]

Hello,

We're attempting to get a working mouse input to the 770 over bluetooth, 
eventually using image processing on a mobile phone to infer movemnt 
from the phones camera (using the 'TinyMotion' algorithm) and using this 
to control a mouse pointer on the 770.

I've tryed to test a bluethooth mouse on the 770 with no luck.  Doing a 
'hidd --connect' seems to go fine the device is recognised and seems to 
be connected.  The usual /dev/input/event3 and /dev/input/mouse1 are 
created but the 770 doesn't take input from the mouse.

After looking at /etc/init.d/x-server.sh I tried changing the mouse 
device by swaping out /etc/input/mouse0 for /etc/input/mice.  This had 
no effect other than to lose the touch screen interface entirly.

Then doing a 'cat /dev/input/mouse0', 'cat /dev/input/mouse1' or 'cat 
/dev/input/mice' produced no output as you would normally get.  Not even 
for the touch screen.  Is there sothing tricky going on here that I'm 
not aware of?  Is the touch screen not behaving as a normal mouse?  And 
since connecting to the bluetooth mouse seems go go fine, why doesn't 
the relevent event or mouse device file not produce any output?

Any quick hints/pointers in the right direction are greatly apreciated!

Cheers,
Gareth
