That is a very valid question and the answer is yes, you still do. Otherwise the board gets powered from the hub, cancelling device discovery.

I suppose gurus at STE found a work around - I don't have more details on the solution.
I have a very basic Dynex 4 port hub. See http://bit.ly/ywaqjT .
Do you still need the OTG adapter?

Good day all,
It is now possible to get input from multiple USB device using a powered USB hub. In my current setup I have a mouse and a keyboard and everything works well. Only basic functionality is supported - USB hot plug and return from hibernation will not work.
This has been tested on landing-snowball builds for kernel 3.0 and 3.1, the latest can be found here:
https://android-build.linaro.org/builds/~linaro-android/staging-snowball/#bu...
The feature has been proven to work with V5 and V11 boards.
Special thanks to our 3-stars kernel engineer Philippe Langlais and the STE connectivity team for their relentlessness work on this problem.
Nicely done Mathieu!
This had been thought to be a hardware problem. Could you expand on the solution a little bit and list the USB hub you're using to test with?
Best regards, Mathieu.
