UMS(4)                   BSD Kernel Interfaces Manual                   UMS(4)

NAME
     ums -- USB HID mouse, touchscreen and digitiser devices

SYNOPSIS
     ums*     at uhidev?
     wsmouse* at ums? mux 0

DESCRIPTION
     The ums driver provides support for USB HID mice, touchscreens and digi-
     tisers.  Access to these devices is through the wscons(4) driver.

     If the touchscreen sensor is poorly aligned, then xtsscale(1) should be
     used to provide calibration results to the ums driver.

SEE ALSO
     xtsscale(1), uhidev(4), usb(4), wsmouse(4)

HISTORY
     The ums driver first appeared in OpenBSD 2.8.

AUTHORS
     HID touchscreen and digitiser support was written by Robert Nagy and
     Matthieu Herrb then later merged into the generic ums driver by Edd
     Barrett.

CAVEATS
     Touchscreen and digitiser pressure sensitivity is not yet implemented.
