STU driver combined installer (autodetects 32/64-bit Windows)

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:

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 Windows7:

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'
