[U-Boot] Uboot 1.1.3 and USB

Hello,

        I would like to post a problem I am encountering regarding Uboot
1.1.3 and USB.

My processor is  an AMD 1550. In short I am seeing the following error
when I execute

The "usb start" command. I also noticed that a CTL:Timeout occurs. It
appears the Uboot

can see the device, but for some reason the device does not respond to
requests. 

 

 I have browsed through Some mail threads from other folks encountering
the same issue, and the resolution for them resulted

In an upgrade to Uboot 1.1.4. I would like to know if anyone has worked
around / fixed such an issue

without upgrading U-Boot.
