Yes, they are correct. I put this system together myself and besides
the front ones work fine with say a USB Flash drive or any other type of
USB device. I thought I had it working, but then after rebooting it
would no longer recognize my USB printer. Thanks anyway though.

Check your MB specs to see if the front ones use a different controller.
If they do it indicates a driver problem rather than a problem with the
printing system.
My MB uses different controllers for the front and rear connectors (4 built
into the chipset and 6 on an additional controller IIRC).

My motherboard manual does not really say one way or the other. I am
assuming they all use the same controller, but I could be wrong.

Of course we all know he is such a fukkin liar!

This is not the first time I have heard of this happening. Apparantly many
enclosures wire the front usb ports in parallel with the rear ports, which
are plugged directly into the motherboard. So the front ports could
experience a drop in voltage, current or both if something is taking power
through the rear ports. This is especially true with inexpensive PSU's.
