My kernel is compiled without support for atkbd. I only use USB keyboards. Attaching is fine but when detaching, any of the keyboards - I tried up to three - the other keyboards freeze. If I attach the keyboard again the other keyboards unfreeze and work as before. The problem has something to do with devd. Detaching works without problems in single user mode or with devd not running. As long as dev does not run *during* detaching things seem to be ok too. Commenting out usb keyboard related entries in /etc/devd.conf or /etc/devd/usb.conf does not help. Commenting out syscons_setkeyboard in /etc/rc.d/syscons does not help either. How-To-Repeat: Attach two USB keyboards. Detach any of them. The still connected keyboards freezes. Reconnect other keyboard. Both keyboards work.

Hi, Is this with or without X11? Can you try 9-stable? --HPS
It seems to be an X11 only problem. My xorg.conf is auto-generated. Hald is running. In xorg.conf I see Driver "kbd". Does X11 bypass kbdmux?
Same problem with FreeBSD-9.1-RELEASE.

Hi, In /etc/devd.conf there are a few lines of code: # When a USB keyboard arrives, attach it as the console keyboard. attach 100 { device-name "ukbd0"; action "/etc/rc.d/syscons setkeyboard /dev/ukbd0"; }; detach 100 { device-name "ukbd0"; action "/etc/rc.d/syscons setkeyboard /dev/kbd0"; }; Can you try to uncomment these? Then restart devd or reboot and try again and see what happens. I believe the devd.conf lines above should be removed. --HPS

I don't have time to debug this currently. To prevent KBD X11 driver unload by /usr/ports/x11-drivers/xf86-input-keyboard change this in the source code: { - xf86AddInputDriver(&KBD, NULL, 0); + xf86AddInputDriver(&KBD, module, 0); return module; } The problem is deeper. When X11 sees that the keyboard is gone it issues some IOCTLs on /dev/console, like the keyboard MODE and then no more keys are received. See using ktrace on Xorg. This is a shared device receiving key-presses for all keyboards as far as I can see and it should only be programmed once. This is currently not handled. Inside the file referenced below code is present to set "x11_driver" to "kbd". Probably changing this will affect the outcome too: /usr/local/share/hal/fdi/policy/10osvendor/10-x11-input.fdi How to reproduce: Plug two USB keyboards using a HAL enabled Xorg server. Unplug one keyboard. Input from the other keyboard disappears until some other keyboard device is plugged again! --HPS

Commenting out does not help. Two choices work for me: 1. devd_enable=NO and hald_enable=YES 2. devd_enable=YES and option "AutoAddDevices" "NO" in xorg.conf

Possibly you need a keyboard device entry in /etc/X11/xorg.conf after this change. --HPS
