Need help to boot debian on USB with more devices connected

[Douglas Lopes Pereira <douglaslopespereira@gmail.com>]

Hi guys,

I'm trying to power up my Sheeva Plug (which is configured to boot
Martin's debian from USB drive) with my USB drive connected over an
USB hub with other devices on it (i.e Usb headset).

Uboot identifies the devices connected but does not recognize my USB
drive and get stuck.

This is what I see from my terminal:

======================= TERMINAL OUTPUT =========================

Does anyone know how to boot my system without removing other stuff
from my usb hub?

Thanks for your attention.
