Public bug reported:
Hello, I'm using Ubuntu Xenial 16.04 (Mint 18) with kernel
4.4.0-21-generic.
I have a Acer C112 DLP picoproyector. I'm installed libam7xxx packages:
$ dpkg -l | grep libam7
ii libam7xxx0.1 0.1.6-2 amd64 library for accessing am7xxx based devices
ii libam7xxx0.1-bin 0.1.6-2 amd64 library for accessing am7xxx devices -

When I connect the projector, this is my syslog:
