Hi all,
the new USB DAC from Teac seems detected as 'Human Interface Device'
instead of 'Audio'. Despite the fact it is based on a standard USB Audio
class v2 controller (Tenor 8802).
Below is dmesg and lsusb outputs.
Does it need to apply a patch in /sound/usb/quirks-table.h ?
If yes, someone could help me to write this patch, please?
Your help would be very much appreciated, Thanks in advance.

Hi, the lsusb shows both HID interface (button?) and audio interface
beneath.

It has both HID and audio interfaces.

Which doesn't prevent Teac from writing buggy firmware.

This violates the USB spec. But I guess it shouldn't prevent the driver
from attaching to the device.
> Audio class v2 interfaces need an interface association
This looks like a bug in the driver; there certainly is such
an descriptor. Daniel?

Right, that's just a warning.

The USB audio driver actually just uses functions from the USB driver
core to access the interface association. However, the USB core didn't
assign it during its probe, which is most probably a result of the
broken descriptor set.
I'm still reading through the sources, maybe we can find a more tolerant
way of handling such devices. If not, we would need to add a quirk for
the device and override the descriptors that way.

And it turned out it is.
Ben, can you try the patch below, please? It's a pretty obvious flaw in
the USB core system which is triggered by buggy descriptors.

Anyone try this yet? I have a fiio E10 and a at&t galaxy S3 rooted and ready to
go. If someone builds me a flashable kernel I'll give it a go.

Try what exactly? Is this message related to the thread you're replying to?
