Installation

Download and run Wacom-STU-Driver-5.4.5.exe

Requirements

The driver is required to use colour STU signature pads with the STU SDK and Wacom Signature SDK. The driver is also required when using any STU signature pad on Windows 8 or 8.1.

Summary

The driver is required for the colour display STU signature pads and also when using any of the STU signature pads on Windows 8.1.
It allows the device to use USB Bulk Transfer to handle the transfer of increased image data size (compared with the mono STU tablets).
On Windows 8 and 8.1 it also disables the Enhanced Power Management setting.

The driver installation merely configures the USB interface for the STU tablet and can be used in all configurations without any detrimental effect.

The need for installation is dependent on the STU model and Windows version as follows:

STU ModelWindows 7Windows 8Windows 10
STU-300, STU-500Not requiredRequired to prevent power save disconnectNot required
STU-520Required for faster image uploadRequired for faster image upload and to prevent power save disconnectRequired for faster image upload

If in any doubt we recommend installing it.

Instructions

Using Wacom-STU-Driver.exe

  • Check that the STU tablet has been disconnected before running the installer.
  • Download the .exe and run it directly from Windows Explorer or in a DOS command line.
  • The .exe autodetects 32 or 64 bit Windows and installs accordingly.

To view the available options use the command:

Wacom-STU-Driver.exe /?  

For example, for minimal prompts:

Wacom-STU-Driver.exe /quiet

Note for Windows 7

To use the /q option the installer must be run in elevated mode to give Administrator rights, e.g.:

Start -> All Programs -> Accessories -> Right-click <Command Prompt>: 'Run as Administrator'
