Hi Sir,
I am facing problem with USB UHCI protocol but my u-boot code is able to detect the connected usb decive but facing problem with communication. The below message is debuging code when I execute USB reset command. I am using u-boot-2009.01 code for PPC405GPr processor. The board design is similar to MPL MIP405T and the board consist of southbridge the usb spec is in southbridge and the usb device is accessed by PCI bus.
=>usb reset

But if I change the code from in common/usb.c file

{

/* We still haven't set the Address yet */

To

addr = dev->devnum;
dev->devnum = dev->devnum - 1;
then I am able to get some information of usb keyboard like below debug message but no change in USB mass storage device.
