[Patch] Logitech TrackMan trackball - unknown device

[Zbigniew Luszpinski]

Hello!

When I connect to my linux 2.6.16.18 box a Logitech TrackMan trackball the 
kernel welcomes me with message:

logips2pp: Detected unknown logitech mouse model 79
input: ImExPS/2 Logitech Explorer Mouse as /class/input/input1

My patch makes TrackMan known for kernel 2.6.16.18. Other recent kernels 
should work with this patch too. After applying patch kenel 2.6.16.18 says:

input: PS2++ Logitech TrackMan Whell as /class/input/input1

have a nice day,
Zbigniew 'zbiggy' Luszpinski
