I have a nighthawk lighted mechanical keyboard, and when hooked into my USB hub (I've tried external powered hubs, and non powered ones) The keyboard just goes dead at random times. If I unplug it and then plug back in, it comes back on.. only to go off again, either 5 minutes or 30 minutes later. This usb hub is connected to the computer using a 20 foot usb extension cable. When I plug the keybaord directly into the back of my computer with no extension or usb hub, it works fine and never goes dead. Reccommendations?

FWIW:  Recommended max length of USB extension cable is approx 16 feet.

And here is my next problem... I bought a 15 foot extension cable, and the problem still persisted. In fact, it was worse.

Well...you only have 3 suspects...the keyboard, the connecting cable, your system.

 

You can validate the extension cable by connecting a different USB device to the system via it.  Which may also validate the system or the keyboard.

 

Process of elimination.

Here is what I am wondering. It isn't the keyboard, because it works perfectly when plugged directly into the tower. I have my mouse plugged intot he same USB hub and extension cable, and it never goes dead. Considering this is a backlit machanical keyboard, with each key having it's own LED, I'm just wondering if it's too much of a power draw? I know some hubs and extension cables maybe deliver better power than others, could that be the problem? And what brand do you think might provide better power?
