Please tell me, what I can do to improve the situation.
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.
I am adding Mario to the receiver list, though he is currently on vacation.
Could you send me the output of
lsusb -v -d 0bda:58f4
running as root if possible ?
Sure, please find it attached.
Thank you.
Could you please try the following patch ?
