Hello,

I'm just working on a AU1x00 based board which has an on-chip OHCI
controller.

I'd like to enable the u-boot USB support for my board and since the
u-boot code is derived from the Linux one I hope my message is not
OT. :)

The problem is that the controller talks with the root hub but when it
starts talking with the USB device (a USB stick) I get:

   ---------- New Device 1 ----------

Maybe someone can suggest to me some useful tips in order to resolve
my problem.

Thanks in advance,
