Some vendors routinely implement new formats without bothering to send a patch
for the uvcvideo driver. It would be easy to do so, but it requires knowing
which format is meant by the GUID. Most format GUIDs are of the form
32595559-0000-0010-8000-00aa00389b71 that starts with a 4CC, but that's not
the case here.
Could you send me the output of
lsusb -v -d 0bda:58f4
running as root if possible ?

I am adding Mario to the receiver list, though he is currently on vacation.

While the 0002 is suspicious, this is pretty close to a color format.
I've recently come across of similar format using D3DFORMAT instead of
GUID. According to the vendor*, this camera module includes an infrared
camera (340x340), so I suspect this is to specify the format it
outputs. A good guess to start with would be that this is
D3DFMT_X8L8V8U8 (0x32). To test it, you could map this
V4L2_PIX_FMT_YUV32/xRGB and see if the driver is happy with the buffer
size. Then render it to make sure it looks some image of some sort. A
new format will need to be defined as this format is in the wrong
order, and is ambiguous (it may mean AYUV or xYUV). I'm not sure if we
need specific formats to differentiate infrared data from YUV images,
need to be discussed.

Isn't 0x32 D3DFMT_L8, not D3DFMT_X8L8V8U8 ?

340*340 is 115600, so this should be a 8-bit format.

If the format is indeed D3DFMT_L8, it should map to V4L2_PIX_FMT_GREY (8-bit
luminance). I suspect the camera transmits a depth map though.

You are right, sorry about that, I totally miss-translate. It felt
weird. This is much more likely yes. So maybe it's the same mapping
(but with the -00002- instead) as what I added for the HoloLense
Camera.

I think we need such a mechanism, yes. Would you like to propose one ? :-)
I've found https://www.magnumdb.com/search?q=value%3A
%2200000032-0002-0010-8000-00aa00389b71%22 and https://docs.microsoft.com/en-us/windows-hardware/drivers/stream/infrared-stream-support-in-uvc that confirm
this is a 8-bit IR format.

Ok, meanwhile I've looked over how this camera was used. It seems
that's it's combined with a IR light in order to create a near field
depth. As we already exposes couple of depth sensors as GREY, I think
your patch is ok, and should be merged. It's not really clear in
general how the driver can really figure-out what type of data is
delivered. So I'm not sure where to start.
