I have a Logitech Cordless Mouseman Optical but im having problems with it in linux. I used to have get a fatal error: mousedev or something but i fixed it with
alias usb-controller uhci-hcd
alias keybdev usbkbd
alias mousedev usbmouse

On my 2.6.5 kernel my wireless mouse doesn't work unless I plug in my corded ps/2 mouse in and then both of them work. (Everything works fine in 2.4.22) Even so, sometimes they stop responding at random times. I would like to not have to plugin in my ps/2 corded mouse in before my cordless USB mouse works. Also, i would like the mouse to respond and not stop responding at random times. When both are pluged in, only my corded mouse's scroll wheel works
thanks, hope i made sense.

i have a wireless usb mouse which works find in slackware 9.1 all i had to do was edit the XF86Config file so that i could use it.

You need to have USB Human Interface Device (HID) enabled in your kernel when you compiled it. do a lsusb to check whether your USB devices has been detected. If not, I suspect it is the kernel. I have been using USB mouses (MX700, MX300, and Wheel Mouse Optical) with Slackware with no problem at all. To get scroll working just search this forum.

right now, its compiled as a module. how do i enable it?

Can you please post your
1. lsusb
2. lsmod
