UMS(4)                       Device Drivers Manual                      UMS(4)

NAME
     ums - USB mouse and touchpanel support

SYNOPSIS
     ums*     at uhidev? reportid ?
     wsmouse* at ums?

DESCRIPTION
     The ums driver provides support for USB mice and touchpanels.  Access to
     the movement data is through the wsmouse(4) driver.

     Be aware that many USB mice will, if the mouse device is not open, detach
     and reattach themselves repeatedly at regular intervals (usually around
     one minute) causing spam on the console and the system log.  This is
     apparently intentional behavior on the part of the hardware
     manufacturers.  The best workaround is to keep the mouse device open,
     either via X11, or, if not using the window system, by running
     wsmoused(8).
