HI! My optical usb mouse was working very well with kernel 2.4.27 but when I upgraded to 2.6 (2.6.8 then 2.6.15), the mouse woudln't work. So I just have to use my laptop's touchpad.
dmesg's output :
Synaptics Touchpad, model: 1, fw: 6.1, id: 0xa3a0b3, caps: 0xa04713/0x10008
SynPS/2 Synaptics TouchPad as /class/input/input1
nothing about other mouse.
You may need more "clues" (sorry english is not my native language)...
I'm a big newbie to linux. Thank you for any help.
