Question about USB power budget

Hi *,
we are trying to connect USB camera to OMAP OSK1592, but there are
couple of problems.

First, led on camera doesn't lit when we connect it to the board.
There is report in dmesg, saying:
sn9c102: V4L2 driver for SN9C10x PC Camera Controllers v1:1.24a
usb 1-1: new full speed USB device using ohci and address 2
usb 1-1: 400mA over 100mA budget!

So, we built a external current source, connected it, but same thing
happens. Also, when we try to open /dev/video, it hangs, for a long
time.

What we should modify, look at, change?

TIA.

My osk complains about the same thing, but I can use
usbgear videoadapter or sweex webcam without any problems.
I used instructions from oskfordummies.hp.infoseek.co.jp
