I've tried...
1. Different devices in this slot
2. All other USB slots on the device work
3. Completely removing power & USB connections from the hub, rebooting system & replugging.

Suggestions?

Looks like I bought this item from MP3car back at the end of March, barely over 5 months ago.

I would repeat those steps on another computer and also try some other devices...just to be 100% certain it is a faulty port.

have you tried it on a different computer? sometimes USB drivers get confused at the OS level.

I have an issue with my p5USB not even turning on. There i 12v going to bolth the hot wires and its grounded good, tested with the multimeter and power is getting to the mole connector fine. I turn it on and get nothing, no lights or anything. Its a brand new unit, never used.

Any idea?

You must have the p5usb plugged into a host device before it gets power. Also please see the technical documentation on the first three links of the product description here if you haven't already.
