Hi,

A hardware glitch of an (optical) PS/2 mouse can cause the mouse pointer
to freeze. Subsequent "killall -HUP moused" gives:

Mar 23 09:11:34 bedside kernel: psm0: failed to reset the aux device.
Mar 23 09:11:34 bedside kernel: psm0: the aux device has gone! (reinitialize).

or:

Mar 23 10:48:27 bedside kernel: psm0: failed to disable the device (psmclose).
Mar 23 10:48:28 bedside kernel: psm0: failed to get status (psmclose).
Mar 23 10:48:28 bedside kernel: psm0: failed to enable the device (doopen).
Mar 23 10:48:28 bedside moused: unable to open /dev/psm0: Input/output error

and attempts to start moused again fail:

Mar 23 09:13:04 bedside moused: unable to open /dev/psm0: Device not configured

How to reinitialize/configure /dev/psm0 without reboot?
5.4-RELEASE-p3 with some security patches.

Thanks,

Lena
