Summary:	PS/2 mouse does not work until usb-uhci module is loaded

Description Trebor A. Rude 2003-04-10 19:39:10 UTC

When I recomplied my kernel to make the USB subsystem as modules, I lost the ability 
to use my PS/2 mouse, either on the console or in X. Upon loading the usb-uhci 
module, the mouse worked again (usbcore didn't matter, mouse was still nonfunctional 
with just it loaded). Immediately removing the usb-uhci module right after loading it 
does not disable the mouse, it still works. 

Reproducible: Always
Steps to Reproduce:
1. Compile kernel with CONFIG_USB=m, CONFIG_USB_UHCI=m, CONFIG_MOUSE=y and 
CONFIG_PSMOUSE=y 
2. Boot to X-windows, ensuring that the usb-uhci module was not loaded at boot time 
3. Try to move the mouse cursor. 
Actual Results:  
The mouse cursor didn't move. 

Expected Results:  
The mouse cursor should have moved, regardless of the state of the usb-uhci module, 
since it's not a USB mouse. 

Kernel used: gentoo-sources-2.4.20-r2 
Motherboard: MSI K7T Turbo2 with VIA KT133A/VT686B chipsets 
Mouse: PS/2 Logitech TrackMan Marble FX

What is your mouse device in XF86Config? If it's /dev/input/*, try loading the "input" and "mousedev" modules instead of "usb-uhci".

Comment 2 Trebor A. Rude 2003-04-11 22:51:21 UTC

My mouse device in XF86Config is "/dev/mouse", which is a link to /dev/misc/psaux (which has 
mode 0666). Loading input and mousedev modules has no effect, but loading usb-uhci makes 
the mouse work.
