From Windows 8.1, Microsoft has revised the power management of the operating system regarding external devices. This change will result in some USB devices in standby (e.g. signotec signature pads) being disconnected from the power to save energy. The devices also do not reactivate.
This affects very old signotec Sigma models, too.
The HID driver disables this functionality for signotec signature pads, so that a continuous operation can be guaranteed. After installation, the connected devices no longer switch off unintentionally, but are available without interruption.
Below you will find the download links to the HID driver, optionally for 32- or 64-bit systems.
You only need the driver if you are using very old signotec Sigma and Windows 8.1 or newer. The driver is not required for newer devices and older operating systems.
Microsoft has also published the following knowledge base article:
