Public bug reported:

I tried different webcams on different machines with Ubuntu 14.04 x86,
x86_64 and Ubuntu 14.10 x86_64.

This is a BIG trouble : No video on x86_64 systems !

Latest tests :
Ubuntu 14.04 x86_64
Lowlatency Kernel and Generic kernel on a second machine.

lsusb : Bus 003 Device 003: ID 093a:2621 Pixart Imaging, Inc. PAC731x Trust Webcam
No image on /dev/video0

vlc : "main demux error: option v4l2-exposure does not exist"
guvcview : "Could not grab image (select timeout): Resource temporarily unavailable"
cheese : no output
skype : nothing

Same cam pluged on my netbook under Ubuntu x86 : worked out of the box with the same softwares.
Tried on a Ubuntu 14.10 x86_64 Laptop : perfect

Two of my customers have the same problem with logitech webcams under
Ubuntu 14.04 x86_64.

Any idea ?
I can't sak them to use normal versions with only 6 months lifetime !
