URB Interupt / JBL Q810

[SWW13]

Description

I'm working on support for the JBL Quantum 810 which seems to report most status with an URB_INTERRUPT.

Is there a way listen to these interrupts? This would probably need some refactoring to implement a headset daemon, which could be out of scope for this project.

I'm also open to other ideas on how to poke the device to give out its state.

All the status updates and commands I have reversed so far are commented my fork of the project (see above).

For example the ANC (Active Noise Cancling) state change when the button on the device is pressed:

ANC On:

ANC Off:

USB Captures of most status changes by the device and software, if somebody likes to look into this: headset-usb-capture.zip

On which OS does the problem happen?

Linux

In general you can use hid_read
or

headsetcontrol --dev -- --receive

In any case it needs to be polled.

There is also an example daemon implementation for the corsair void:

HeadsetControl/src/devices/corsair_void.c

Line 392 in eeab45c

static int void_daemonize(hid_device* device_handle)

But was not really continued. Its a bit hard to integrate it with the rest of the application, probably also needs a special design regarding uniform output.
