Very Computer

Hi everyone,

I have a newbie question.
What should i do to enable Logitech USB optical mouse in Linux?

Thanks.

ok, I'm no expert but I have that mouse the ergonomic looking one not the
standard shaped one and it runs in linux fine.  first it would help if we
knew
what distribution you're using?

now for some things you can try

I have a newbie answer, as a fellow newbie. This is an alternative
answer, utilizing a PS/2 port. If this won't work for you or you don't
want to do it this way, by all means skip it :o) But just in case...

I just bought the same mouse, to replace the old serial mouse on my
Win95/Slack box.  It's pretty old, no USB support here, so I plugged the
mouse into the PS/2 port using the supplied adapter, booted into Win95
to verify it was working, then rebooted into Slack and started scouring
the Net for help.

The best thing I did was Lynx over to groups.google and search their
wonderful archives.  A 1997 post from Andreas Ortmann Jaunsen gave me
the information I needed to get my mouse working in Slackware 7.1 in no
time, and here it is:

Quote:>1) make sure your /dev/mouse is linked to /dev/psaux
>   (rm /dev/mouse ; ln -s /dev/psaux /dev/mouse)

(I think /dev/psaux may have other names in other distros; I'm not sure)

Quote:>2) if you use gpm start it with > gpm -t ps2
>   To change permanently, edit your /etc/rc.d/rc.local file

( I had to add   gpm -k     before   gpm -t ps2   in the
/etc/rc.d/rc.local file. Hopefully someone will tell me a better way.
Works, anway.)

Quote:>3) make sure your XF86config has the following line(s) under
>   section "Pointer"
>            Protocol "PS/2"
>            Device   "/dev/mouse"

(/etc/XF86config for me)

BTW, I am using gpm as well as X (3.3.6 currently), no problems AFAICT

Make sure your kernel supports USB. Ie, is the USB interface
recognized when you boot? Scna through dmesg or /var/log/messages
looking for references to USB:

If your kernel doesn't seem to recognize your USB hardware you
will have to compile a new one with USB support explicitly
enabled.  Depending on your kernel version, this may mean
downloading the kernel sources for a newer version than you
currently have.  IIRC, USB support was backported into kernel
2.2.16 but my experience is that it didn't work well until kernel
2.2.18 so if you're running an earlier kernel you may want to
pick up at least v2.2.18 or newer. I think 2.2.19 is the current
latest in the 2.2.x series.  If you have one of the 2.4 kernels
you should be set.

If your mouse has a wheel try using the Intellimouse protocol.
It works very nicely with my Logitech optical wheel mouse.
