It just probes and attaches to USB device, creates a device entry and feeds reassembled packets from the hardware to it. Depending on compile-time kernel options it supports either native or evdev operation modes. .Pp To get the mouse working in .Xr X 7 in native mode, install .Pa ports/x11-drivers/xf86-input-egalax . .Pp To get the mouse working in .Xr X 7 in evdev mode, install .Pa ports/x11-drivers/xf86-input-evdev . .Sh FILES .Nm creates a blocking pseudo-device file, .Pa /dev/uep0 in native mode or .Pa /dev/input/eventN in evdev mode. .Sh SEE ALSO .Xr usb 4 , .Xr loader.conf 5 , .Xr xorg.conf 5 Pq Pa ports/x11/xorg , .Xr egalax 4 Pq Pa ports/x11-drivers/xf86-input-egalax , .Xr evdev 4 Pq Pa ports/x11-drivers/xf86-input-evdev . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Gleb Smirnoff Aq Mt glebius@FreeBSD.org . .Sh BUGS .Nm cannot act like .Xr sysmouse 4 , as .Xr sysmouse 4 does not support absolute motion events.
