Help me please to make usb working

Hi
I have beagleboard and trying to connect usb device to my board, but
it doesnt work.
What I have done:
1. Connected ID pin to GND and external power to my board. I tested
usb with usb-flash, usb-hub with ext.power.
lsusb command shows this all times: Bus 001 Device 001: ID 1d6b:0002.
No more usb devices.
2. I checked power on Vbus pin. There is no power.
3. Then I disconnected ID pin from ground and connected board to my PC
using ordinary USB cable. Should Windows find new usb device in this
case? (there is no any new device in my case)

So everything works fine except USB OTG. I have B7 board revision and
default Angstrom kernel (made everything like here:

Would you be so kind to give me some advices to find out what
happening with my board? I new to linux )
