Description Brian J. Murrell 2015-09-27 17:13:02 UTC

+++ This bug was initially created as a clone of Bug #44281 +++

This bug has come back.  I am seeing it in the 4.1.7-200.fc22.x86_64 kernel on Fedora 22.  Camera is a Logitech Quickcam Pro 5000.

Tell-tale sign of:

[ 3026.173641] usb 1-1: 3:3: cannot set freq 16000 to ep 0x86
[ 3031.183564] usb 1-1: 3:3: cannot set freq 16000 to ep 0x86
[ 3036.194392] usb 1-1: 3:3: cannot set freq 16000 to ep 0x86

in dmesg, but most importantly, and why I set it to blocking, is that it blocks pulseaudio which then blocks any desktop environment based on GTK (or anything else using PA).  So quite nasty.
