Dang, this must be related to bootrom somehow then. Fabio, can you confirm the 
following:

If you turn off the mx28 board, connect usb flashdisc, turn it on -- do you see 
the flashdisc led blinking? Any idea what might cause it? This patch forced the 
VBUS off, so very early in uboot, the USB flash has no way to blink (unless 
there's some surge).
