On the laptop, after getting the authorisation dialogue, I get this
message from the input service:
Jun 18 16:27:12 snoogens input[4052]: New input device 00:19:C1:7D:2E:FA ()

But no device is actually created.

The class show up in the bluez files as 0x000508, which seems to be
correct for a gamepad.
The kernel has HIDP support built in to a module, and seems to be
getting automatically loaded.

Could it be that I'm not setting the device flags to
HIDP_BOOT_PROTOCOL_MODE? (Incidentally, is there any way to check
whether a device is in this mode, or in full HID mode?)

Any idea on how to debug this?
