Subject: [PATCH 1/2] macOS: Use unique IDs for HID paths
|
|
|
|
If available, use the system-generated unique ID for HID device paths instead of a transport/vid/pid/location tuple.
|
|
The Mayflash Dolphinbar registers four HID devices (regardless of the number of connected Wiimotes) which had the same path with the previous path building method, causing a bit of confusion when detecting and connecting to Wiimotes.
|
|
The unique IDs do not change if the computer is suspended and resumed, but do change if the HID device is unplugged/replugged.
