I would think so to (mine did).

Are they USB 2.0?  Reason I ask is that if you're running ribbon cables from your motherboard to the front USB port, a ribbon cable will probably pick up too much noise for  USB 2.0 to work reliably.

You need shielded twisted pairs to work well.  That being said, when I plug my Treo into my front usb ports, it tells me it's unrecognized about 1 out of 5 times.  This is on my work computer (a Compaq workstation), so it should be properly designed in terms of cabling.  Maybe we have too high standards.

I am using the wires from the case (hard wired tot he front ports, directly to the header on the motherboard.  They are USB 2.0.  This is much worse as far as reliability, those ports often won't work at all.  What is more strange is that the left front usv port works fairly well 95% of the time, it is just the right one that gives me most of the problem.  It was the same way on the other case which is why i am thinking it is a USB header problem on the MB.

Doesn't the specification call for proper shielding around USB cables, even if it's an internal cable?

acevedor2:

To be honest, I have built about 20 computers in my life, at least a dozen of them had front USB ports.  The only cables being used are the cables provided by the case manufacturer that are attached already to the case from the factory.  All you have to do is plug them into the USB header on the MB.  Whether they are shielded or not I couldn't tell you, but I what I am pretty positive that you don't have to do anything else special to them before you connect them.
