we asked Cortron again about a possible auto-detection sequence but they
didn't implemented anything in this matter. So I updated the patch
according your recomendations and Chris tested again with the Trackball,
with success. If you're ok with that, I'll resubmit it with proper
description/signed-off-by header.
