Willard,
Did a little digging. Both the Galaxy Tab 2 7.0 I705, and Galaxy Tab 2 7.0
P3100 support OTG devices. The 7" tab 3 doesn't. From your description it
sounds like yours does support the OTG serial device but isn't passing power to
it which is strange. If you have a multi-meter handy, check the outer two
connection pins where the FTDI would plug in. Is it 5V? If not, it may be the
cable. Another test would be to plug a USB flash drive into that cable and see
if it powers up. If not then it's definitely a cable issue.

Willard,
Thanks for the update. I have not tried it with a Galaxy tab. I have used a
Nexus 7, Motorola Moto-X, Droid Mini and have received reports about a Nexus 5.
I'll look into the Galaxy. Maybe there is a setting for powering the OTG
devices. I know with my phone that the FTDI chip draws power and maybe the
Galaxy is not allowing that in order to conserve as much power as possible.
What version of the Android OS is installed on your tablet?

So I'm getting the gear together to try out Android mcomm and got the FTDI
rs232 adapter today. Gave it a try....
And my tablet (Samsung Galaxy Tab 2 7) flatly refused to power the adapter.
Hooked it up through a powered hub and it works.
I'm still gonna give mcomm a try but the requirement of wall power for the hub
will make it, well, a lot less "on the go". :-(
Now I want to be clear here, this is NOT a complaint about mcomm or any other
m100 goodness, just a warning that android devices can be awfully fussy about
powering USB gizmos and people planning on using mcomm should just be aware.
