## DESCRIPTION

**js\_x** is an XFree86 input driver for JamStudio devices.

The **js\_x** driver functions as a pointer input device, and may be used as the X server's core pointer.

## SUPPORTED HARDWARE

This driver supports the KB-Gear JamStudio pentablet. This X-Input driver should work on any OS supporting the hiddev raw USB HID driver.

## CONFIGURATION DETAILS

Please refer to [XF86Config-4(5x)](/XF86Config-4/5x.md) for general configuration details and for options that can be used with all input drivers.  This section only covers configuration details specific to this driver.

- **Option *"Device"* *"path"***

  sets the path to the raw HID device to which the tablet was assigned. This option is mandatory.

- **Option *"MinX"* *"int"***

  - **Option *"MaxX"* *"int"***

  - **Option *"MinY"* *"int"***

  - **Option *"MaxY"* *"int"***

  sets the minimum and maximum values returned for the absolute X,Y axis of the pen tablet. These values default to 0-8000 for X and 0-6000 for Y. It should generally be safe to leave these values untouched.

- **Option *"PressMin* *"int"***

  - **Option *"PressMax* *"int"***

  sets the minimum and maximum values returned for the pressure sensitive tip. These values default to 0-127. It should generally be safe to leave these values untouched.

- **Option *"PressDiv"* *"int"***

  sets the divider for the returned pressure value. This option will allow you to return a smaller set of values for the pressure sensitive tip allowing for finer control. The returned value is computed as follows:

  - *X / PressDiv = returned value*

    where X equals the value read from the tablet.
