Title:
uvcvideo: IPEVO Ziggi-HD document camera stops working on kernel
4.4.0-171
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have a IPEVO Ziggi-HD document camera (1778:0207) that refuses to
operate on kernel 4.4.0-171 or newer. On such kernels, uvcvideo fails
with the kernel message 'uvcvideo: No streaming interface found for
terminal 2' and no `/dev/videoX` device is created.
The camera operates correctly on kernel 4.4.0-170.
Ubuntu release: 16.04.6 LTS
Attached in a tarball:
* a relevant /var/log/syslog fragment captured when device plugged in
* `cat /proc/version_signature`
* `sudo lspci -vnvn`
