[Elecraft] USB Cable Power Requirements

[Joel Black]

Are there any power requirements for the KUSB cable?  I have looked all 
over the Elecraft page.  If the answer is there, I cannot find it.

I bought a Mac with only four USB ports and am going to purchase a 
powered hub.  One of the hubs offers seven ports, but only 2 A for all 
the ports.  The four-port version offers a full 500 mA per port.

Thanks,
