Hi all, I'm struggling to understand what the UsermodeHID option in BlueZ does, and I'm not finding a good source of documentation on it. I understand that using this option has the kernel pass raw HID traffic to a usermode process for interpretation, rather than doing this directly in the kernel, and this has advantages as far as debuggability, pluggability, fault isolation, etc. However, my questions— - What is the usermode process? Do I have to start it somehow, or does it start on its own? Is it an already running daemon? - What is the communication channel between the kernel and user process, and how can I listen in on the traffic? - Is the usermode process directly managing things like devfs nodes (eg, /dev/input/js0), or does it communicate back to the kernel for that? - As a user, what are my options for swapping out the usermode process if I want to modify its behaviour? For example, handling disconnects or pairing in a different manner than the default?
