From: Roderick Colenbrander <roderick.colenbrander@sony.com> This new property can be set on input devices to blacklist them from getting picked up by joydev. This is meant for devices, which pass joydev its heuristics, but for which there is no good generic way of updating the heuristics.

Some devices pass its heuristics, but don't +make sense to expose. In some cases the generic heuristics can be updated, +but in other cases this is not easy.
