I had asked about how to power a Unbranded (Best Buy) Windows 8.1 tablet while
using the
one micro USB for data as well as charging. I received several good
suggestions but have
found another solution.
I bought a DIgi Anywhere USB/5, which allows connecting to 5 USB ports over
Ethernet.
I use a Dell Venue 8 Pro and like many new tablets and phones it uses
USB On The Go for connectivity. Dell sells this:

and it allows what you need. USB OTG negotiates charging and data
according to
Why have such seemingly simple things gotten so hard?
Like nobody ever figured one would want to use and charge a device at
the same time?
This capability should be part of the tablet.
I'd comment on how hard it is to key a radio via a computer these days
but won't.

For $59 you must expect to not have all the bells whistles that a $300
tablet
would have. They have to cut cost somewhere.

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
Hmm, that's interesting. Have you tried a powered USB hub? I would think that
should work.

Hi Warren,
Another option would be either a Bluetooth or WiFi to serial port adapter. That
way you could connect wirelessly to the elecraft and still power your tablet.

Mark,
I would think the powered USB hub could work as it would provide power
to devices downstream of the hub. They are not to be confused with a
passive USB hub, which only passes on the power available from the
tablet's USB port.
Powered hubs are easy to identify as they are usually provided

Back feeding a Raspberry Pi from USB bypasses the fuse in the
Pi. It is probably a good idea to include one in the power
supply to the hub. That is how I powered my Pi.
When I changed to a Beaglebone Black, the USB wouldn't work. I
had to remove power to the hub and power it from the
I bought a win 8.1 (not RT) tablet from Cowboom for $59, hoping to interface it
using its
micro USB port. However the USB port is the only way to provide power to the
thing,
and battery life is such I'd like to leave it on charge while operating, while
not losing the
USB port data
