You should be looking for a USB-C docking adapter. It supplies power for charging and extends the USB for devices to connect. They are relatively new - there aren’t that many USB-C systems out so far, so you should expect them to be somewhat expensive. But, the adapters are available. I know that Apple sells one for their MacBook, which uses USB-C. Might be a good starting point, but keep looking to find what you really want.
A standard USB hub will not provide what you need... 73, Jack, W6FB > On Jul 7, 2015, at 8:57 AM, Mark N2QT via Elecraft <elecraft@mailman.qth.net> > wrote: > > Actually the issue is the tablet is able to supply power to external devices, > which must be > disabled when the unit is being charged from an external source.
