USB OTG port not working on Angstrom

I have been trying out Ubuntu and Angstrom and some things I liked
better in either distribution, but decided to focus on Angstrom. But
one issue troubles me:

The OTG usb port does not work (no power) on my Angstrom installation,
while on Ubuntu, it works right away.

The version of Ubuntu is:

Linux beagleboard 2.6.32.8-x8.0 #1 PREEMPT Thu Feb 11 00:08:02 UTC
2010 armv7l GNU/Linux

And Angstrom:

Linux beagleboard 2.6.32 #1 PREEMPT Fri Feb 26 09:58:46 CET 2010
armv7l GNU/Linux

I am completely lost in where to continue fault finding this issue.
Any pointers would be really appreciated - I need a port for WLAN and
one for a camera in my application, and would really not like to put a
a hub in the mix.

In Angstrom you need to ismod one of the otg gadget drivers to bring
otg usb bus for the system..

Here's the diff i use for Ubuntu's kernel :

Thanks.

I took a while for me to compile a beagleboard image, but when I got
there your patch worked wonders.

Seems my next task will be finding out why it only discovers usb
devices on boot :wink:

Just for the record: I believe the discovery issue was fixed with:

opkg install hotplug
