STU Installation
STU Driver
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 Model | Windows 7 | Windows 8 | Windows 10 | Windows 11 |
---|---|---|---|---|
STU-300, STU-500 | Not required | Required to prevent power save disconnect | Not required | Not required |
STU-520 | Required for faster image upload | Required for faster image upload and to prevent power save disconnect | Required for faster image upload | Required for faster image upload |

If in any doubt we recommend installing it.
