NAME
uep -- eGalax touchscreen driver
SYNOPSIS
To compile this driver into the kernel, place the following lines into
your kernel configuration file:
device uep
device usb
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
uep_load="YES"
DESCRIPTION
The uep driver provides support for the eGalax onscreen touch panels.
The driver is stub. It just probes and attaches to USB device, creates
device entry and feeds reassambled packets from the hardware to it.
To get mouse working in X(7), one needs to install
ports/x11-drivers/xf86-input-egalax.
BUGS
uep can't act like sysmouse(4), since the latter does not support
absolute motion events.
FILES
uep creates a blocking pseudo-device file, /dev/uep0.
