This article addresses Legacy Hardware and Custom Linux Driver Support

Elo periodically updates Linux touch drivers to add new features, support additional touch controllers, and ensure compatibility with modern operating systems and environments. As part of this process, older hardware, operating systems, or libraries may no longer be supported.

The Issue

When customers upgrade from legacy Elo touch hardware to newer models, they may encounter compatibility issues if their system environment cannot support the latest Elo drivers. This situation is especially common when older touch technologies are retired and replaced by newer ones in Elo products.

Example Scenario

A customer using an embedded Linux environment relied on an older Elo MTUSB driver that worked with their legacy monitors. When they upgraded to new Elo monitors, the touch controllers required driver support that was only available in newer driver releases. However, the customer’s environment could not support the updated drivers due to library version requirements.

Elo’s Approach

In rare cases where customers are unable to update their system environment, Elo may provide a custom driver build. These custom builds are:

• Based on older driver versions.
• Updated to add support for newer Elo hardware.
• Created to address specific customer needs when no other solution is viable.

These drivers are not part of Elo’s standard release process and are not distributed through the Elo website or document control system. They do not undergo Elo’s standard QA or validation procedures and are provided as-is for special customer requirements.
