Parent device in terms of the autoconfiguration framework is .Xr pckbc 4 , the PC keyboard controller. .Dq pms is a generic driver which supports mice using common variants of the PS/2 protocol, including wheel mice of the .Dq IntelliMouse breed. Wheel movements are mapped to a third (z-) axis. The driver is believed to work with both 3-button and 5-button mice with scroll wheels. Mice which use other protocol extensions are not currently supported, but might be if protocol documentation could be found. Mouse related data are accessed by .Xr wsmouse 4 devices. .Pp The .Nm driver has been updated to attempt to renegotiate mouse protocol after seeing suspicious or defective mouse protocol packets, or unusual delays in the middle of a packet; this should improve the chances that a mouse will recover after being switched away or reset (for instance, by a console switch). .Sh SEE ALSO .Xr opms 4 , .Xr pckbc 4 , .Xr ums 4 , .Xr wsmouse 4 .Sh AUTHORS The .Nm driver was originally written by Christopher G. Demetriou. The changes to merge the .Dq IntelliMouse protocol in, and reset the mouse in the event of protocol problems, were contributed by Peter Seebach. Special thanks to Ray Trent, at Synaptics, who contributed valuable insight into how to identify bogus mouse data. .Sh BUGS It is possible for the driver to mistakenly negotiate the non-scroll-wheel protocol, after which it is unlikely to recover until the device is closed and reopened.
