Answered: USB Extensions for VEXnets

So I’ve heard that the VEXnet keys should be placed such that it should not be enclosed by metal in order to keep the signal strong. One thing I’ve noticed on some robots: they use a USB extension cable to plug one side into their cortex, and the other to their VEXnet key so that they can strap their VEXnet key on the outside of their robot, for what I’m assuming is for a better signal. Is this legal and/or common practice?

Yes, this is explicitly allowed as per <R7j>.
