Hi,
I'm not subscribed to linux-usb mailing list so I found your post just by a
pure luck. I've sent the patch for:
streaming_maxburst streaming_maxpacket streaming_interval
problem earlier this week. Try this patch [1]:
BTW please CC me if you will have another discusion in your thread (I will try
to not forget it myself if I will continue in my thread).
P.S. Which userspace do you using, original uvc-gadget or unofficial repo [2]?

[PATCH] usb: gadget: uvc: Missing files for configfs interface
Commit 76e0da34c7ce ("usb-gadget/uvc: use per-attribute show and store
methods") caused a stringification of an undefined macro argument "aname",
so three UVC parameters (streaming_interval, streaming_maxpacket and
streaming_maxburst) were named "aname".
Add the definition of "aname" to the main macro and name the filenames as
originaly intended.
