 Posted: Wed Apr 16, 2003 1:52 pm Post subject: usb mouse with devfs |
 |
|
Get a kernel message whenever my usb mouse is being plugged in or taken out. Have the dirs /dev/mice and /dev/input, but both are empty. My devfs.conf mentions someting like ^input/mous0 etc. What should I do to get it running. The documentation is extremely vague, please help me out here.
Cheers! |

I assume the ^input/mous0 was a typo.
My part of devfs.conf looks like this:
| Code: | # Create /dev/mouse
LOOKUP ^mouse$ CFUNCTION GLOBAL mksymlink misc/psaux mouse
REGISTER ^misc/psaux$ CFUNCTION GLOBAL mksymlink $devname mouse
UNREGISTER ^misc/psaux$ CFUNCTION GLOBAL unlink mouse
# Manage USB mouse
REGISTER ^input/mouse0$ CFUNCTION GLOBAL mksymlink $devname usbmouse
UNREGISTER ^input/mouse0$ CFUNCTION GLOBAL unlink usbmouse
REGISTER ^input/mice$ CFUNCTION GLOBAL mksymlink $devname usbmouse
UNREGISTER ^input/mice$ CFUNCTION GLOBAL unlink usbmouse

Also, do you have devfs starting at boot. If using lilo should have this line in /etc/lilo.conf : ( append=" devfs=mount" )
| Code: | # Linux bootable partition config begins
image = /boot/bzImage-2.4.20
root = /dev/hdb2
label = Gentoo
append=" devfs=mount"
read-only |
In my /dev/input folder I have devices mice and mouse0 , but don't have a /dev/mice folder.
If none of that helps, what modules (if loading as modules) do you have loaded? Like: input usb-uhci, hid, mousedev . |

Thanks for your reply.
Well, actually, my settings are identical to yours. First of all, I mount devfs at boot. In fact, the file /dev/.devfsd exists and proves that devfs has been mounted. Secondly, I have also the devfsd daemon running. At this stage, I have compiled the USB support in the kernel, just for convenience so that I don't need to think about loading modules. I know, this is dirty. Anyway, it seems that most settings are correct, but I do fear some kernel paremeters to be incorrect. What are necessary kernel parameters in addition the ones specified at
http://www.linux-usb.org/USB-guide/x194.html ?
I repeat once again.
At this stage I do have an entry /dev/usbmouse, and the kernel logs messages. Devfs is mounted at boot and the deamon is running. However, when I do cat > /dev/usbmouse, no garbage appears while moving the mouse. Am I missing something crucial? |
