Never return V4L2_COLORSPACE_DEFAULT. From the standard:
"""
In the absence of this descriptor, or in the case of
“Unspecified” values within the descriptor, color matching
defaults will be assumed. The color matching defaults are
compliant with sRGB since the BT.709 transfer function and
the sRGB transfer function are very similar.

Hi James
could you check if this fixes your issue:

- if (ret && !multiple_classes)

If so I will prepare v4 of

Race condition in the firmware?
Not enough current to complete a request and end up in some kind of brown-out?
It is difficult to know without access to the hardware :)
Maybe you can replicate what causes the error with just v4l-ctl calls
and then ping the manufacturer with a simple repro.

Hmm, think that might be the way the camera might be indicating commands
are being sent too fast? Maybe a retry on the first -EPROTO seen would be
enough to fix it?

I do not think that it is part of the uvc standard :).
What is the model/vendor of the camera?
You might have to implement a quirk for it.

The vendors seem to think the windows uvc driver is the standard I think. :)

No idea, something someone found in china from a random vendor.

Hmm, looking at a pcap the windows uvc driver looks like it might be sending
a bunch of GET_CUR multiple times for the same request, maybe it makes sense
to try and emulate the behavior there.

Seems it was just due to the timeout being too short, this seems to
fix the issue:
https://lore.kernel.org/linux-media/20211114085236.2345589-1-james.hilliard1@gmail.com/
The camera now passes all v4l2-compliance tests with this change applied.
