Do you have the brand/catalogue name for the device on which you tested this? I found a "YCCTEAM" joypad, but it seems that the audio interface is supposed to work (maybe that's only on wireless?). Do you think you could also look into a patch for BlueZ's cable pairing plugin? It uses 0x81 too, even though it does have some fallback code. https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/plugins/sixaxis.c#n111

I don't have access to the hardware at the moment, I was testing this at a friend's place, after their son was disappointed that the game controller he had just bought didn't work with RetroPie.

There are clones of DualShock 4 that are very similar to the originals, except of 1) they do not support HID feature report 0x81 and 2) they do not have any USB Audio interfaces despite they physically have audio jack. Such controllers are working fine with Linux when connected via Bluetooth, but not when connected via USB. Here is how failed USB connection attempt looks in log: usb 1-5: New USB device found, idVendor=054c, idProduct=05c4, bcdDevice= 1.00 usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-5: Product: Wireless Controller usb 1-5: Manufacturer: Sony Computer Entertainment sony 0003:054C:05C4.0007: failed to retrieve feature report 0x81 with the DualShock 4 MAC address sony 0003:054C:05C4.0007: hidraw6: USB HID v81.11 Gamepad [Sony Computer Entertainment Wireless Controller] on usb-0000:00:14.0-5/input0 sony 0003:054C:05C4.0007: failed to claim input This patch adds support of using feature report 0x12 as a fallback for Bluetooth MAC address retrieval. Feature report 0x12 also seems to be used by DS4Windows[1] for all DS4 controllers.
