I am unable to get my USB mouse working. I am running (Vector) Slack 8.1 with a just recompiled 2.4.20 kernel. It didn't work before I recompiled. In the messages file, I see:

Apr 27 18:11:43 oswald kernel: hub.c: new USB device 00:1d.0-1, assigned address 3
Apr 27 18:11:43 oswald kernel: input0: Logitech USB-PS/2 Optical Mouse on usb1:3.0
Apr 27 18:11:44 oswald /etc/hotplug/usb.agent: Modprobe and setup usbmouse hid for USB product 46d/c00e/1100
Apr 27 18:11:45 oswald /etc/hotplug/usb.agent: Modprobe and setup mousedev for USB product 46d/c00e/1100

My XF86Config looks like (for the relevant sections):
Section "ServerLayout"
Identifier "XFree86 Configured"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "USB Mouse" "CorePointer"
EndSection

Section "ServerFlags"
Option "AllowMouseOpenFail" "true"
EndSection

Section "InputDevice"
Identifier "USB Mouse"
Driver "mouse"
Option "Device" "/dev/input/mice"
Option "SendCoreEvents" "true"
Option "Protocol" "IMPS/2"
Option "ZAxisMapping" "4 5"
EndSection

Unfortunately, cat /dev/input/mice just yields cat: mice: No such file or directory. for a while, before the recompile/reboot, I at least had cat /dev/input/mice yielding a blank line (but not responding to mouse movements).

So, how do I figure out where my mouse is? Are there any ideas to help me? Do I need to insert a module even though I compiled the usb modules into the kernel, and they appear to detect the mouse?
