I've applied your first patch, but I'd like to understand a bit better
how you'd end up in this situation. Is this accomplishable through BlueZ
APIs or only if one goes and messes with the storage directly? Either
way, is this the best approach or should we consider still creating the
input device but just ignore the bits that depend on the SDP record?
