I tested with the latest kernel image I saw, which appears to be 5.7.1:
ii linux-image-unsigned-5.7.1-050701-generi 5.7.1-050701.202006071230 amd64
Linux kernel image for version 5.7.1 on 64 bit x86 SMP
jlquinn@cerberus:~$ uname -a
Linux cerberus 5.7.1-050701-generic #202006071230 SMP Sun Jun 7 12:32:55 UTC
2020 x86_64 x86_64 x86_64 GNU/Linux
When I first plug in the device, /dev/video0 appears as expected. I
then start vlc and attempt to input from capture device /dev/video0 and
audio hw3,0. After several seconds, I get kernel warnings and
/dev/video0 disappears.
I've attached the segment of kernel log from the time I plug in the
capture device to the time things blow up. I've also attached lsusb -v
taken after I plug in the device and before I attempt to use it.
