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`
