# uep(4freebsd)

eGalax touchscreen driver

## 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)](/loader.conf/5.md):

```
uep_load="YES"
```

To compile this driver with evdev support enabled, place the following lines into the kernel configuration file:

**options EVDEV\_SUPPORT** **device evdev**

## DESCRIPTION

The **uep** driver provides support for the eGalax onscreen touch panels.

The driver is a stub. 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.

To get the mouse working in [X(7)](/X/7.md) in native mode, install *ports/x11-drivers/xf86-input-egalax*.

To get the mouse working in [X(7)](/X/7.md) in evdev mode, install *ports/x11-drivers/xf86-input-evdev*.

## FILES

**uep** creates a blocking pseudo-device file, */dev/uep0* in native mode or */dev/input/eventN* in evdev mode.

## AUTHORS

The **uep** driver was written by Gleb Smirnoff ⟨*glebius@FreeBSD.org*⟩.

## BUGS

**uep** cannot act like [sysmouse(4)](/sysmouse/4.md), as [sysmouse(4)](/sysmouse/4.md) does not support absolute motion events.
