Things look quiet here. But I've been doing a lot of blogging at dan.langille.org because I prefer WordPress now. Not all my posts there are FreeBSD related. I am in the midst of migrating The FreeBSD Diary over to WordPress (and you can read about that here). Once the migration is completed, I'll move the FreeBSD posts into the new FreeBSD Diary website.

4.0-R: Quick and Dirty USB Mouse support
Gentlebeings --

For your quick and dirty USB Mouse support, please following these easy steps:

  1. Add the appropriate entries to your kernel configuration file:

    device uhci
    device ohci
    device usb
    device ums
  2. Add the appropriate lines to your /etc/rc.conf file:

    moused_enable="NO"
    moused_flags="/dev/ums0"
    usbd_enable="YES"
    usbd_flags=""
    (though I like -vv personally, just for the scroll factor)
  3. Make sure your /etc/usbd.conf has these lines in it:

    device "Mouse"
    devname "ums[0-9]+"
    attach "/usr/sbin/moused -p /dev/${DEVNAME} -I
                   /var/run/moused.${DEVNAME}.pid"

  4. Create the device entry

    cd /dev
    ./MAKEDEV ums0
  5. Rebuild your kernel and reboot.  As always, I would recommend saving /kernel to /kernel.stable before trying out the new kernel.  It's a handy thing to have around anyways.
  6. Add the following line to /etc/rc.conf which enables the mouse on all virtual terminals:

    allscreens_flags="-m on"

I don't think I forgot anything, but if I did please let me know :)

References and man pages
Benn recommends the following man pages:
  • usb(4)
  • usbd(8)
  • usbd.conf(5)
  • usbdevs(8)
  • ums(4)

If you have X11 pointed at sysmouse, then this will work just fine.  And it will support plugging/unplugging the mouse at runtime without the need of a manual HUP.

Addenda
You have to do this:

vidcontrol -m on

to actually enable it on the terminal.  Alexander Anderson said he found this piece of info on the man page for moused(8) by accident.  He also suggested step 6 above.
