When I moved it to a USB 2.0 port, the printer immediately started working properly using the Xerox Phaser 3150 driver that comes with cups, just like it always did under Centos 6.

Frank, et al:
FYI, and this may or may not be related...

I bought a Venus DS3R PRO2 storage box a while back. this device offers
USB-3 or eSata connectivity. I quickly found that when using a USB-3
cable and connecting to the USB-3 ports on my motherboard, that it would
work for a short while then the system could no longer access it, the
/dev/<node> would disappear and the only way to get it back was to
reboot. (note that eSata worked fine, and still does).

incidentally, using USB2 appears to work even when connected to the
USB-3 connector on the mommyboard.

I tried a rawhide live cd and it had the same issue, but I reported it to
Fedora (I know, we're on a  Cenots list right now) and in a while a fix
came down. So perhaps it would work on C7, haven't tried it yet.
