Jesse,
That is an interesting setup you have there.
See this link: http://en.wikipedia.org/wiki/File:Mini_usb_AB.jpg
What needs to get in to the OTG port on the Snowball is a true mini A (shown on the left in above link). If a mini B (shown on the right) is used the board will get powered and devices won't be discovered.
Mini A connectors are very hard to find in the US. If you're fortunate enough to have one go ahead and try it.
Mathieu.

Silly question. Do you know if an adapter would cause a problem? The hub I have is mini-USB to the hub, and the cable that came with it is mini-USB to USB-A (I have an adapter to make the cable mini-USB at both ends).
cheers, Jesse

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 .

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.
