Hi Alexey,
I tested all the modes you reported and came up with te following table:
| Dell | Logilink
-------------------------------+--------------------------
without quirks | working | not working
UVC_QUIRK_STATUS_INTERVAL | working | not working
UVC_QUIRK_PROBE_MINMAX | working *1 | working
UVC_QUIRK_PROBE_EXTRAFIELDS | not working | not working
UVC_QUIRK_BUILTIN_ISIGHT | not working | not working
UVC_QUIRK_STREAM_NO_FID | not working | not working
UVC_QUIRK_IGNORE_SELECTOR_UNIT | working | not working
UVC_QUIRK_FIX_BANDWIDTH | working | not working
UVC_QUIRK_PROBE_DEF | working | not working
UVC_QUIRK_RESTRICT_FRAME_RATE | working | not working
*1 the image looks very pixelated
So sorry for the report for the Dell webcam. I had quirks enabled by default
for my Logilink-Webcam and didn't test it without quirks :-/
But the Logilink USB-Webcam is only working with quirks set to 0x2
(UVC_QUIRK_PROBE_MINMAX). Otherwise I get 'Unable to set format: Input/output
error\n Init v4L2 failed !! exit fatal' when starting luvcview.
Greetings,
Josef
