Hi,

I am developing a USB stack on OHCI controller.The target
environment is
MPC5200B.

The code behaves properly and enumerates the LS
(Low-speed)devices
perfectly.I am able to communicate with the keyboard.

But if i plug in any FS/HS (Full-speed/High-speed) device I
get "device not
responding" error on get descriptor request . I tried
toggling the speed 'S'
bit in endpoint descriptor structure , but with no effect.

Can any body let me know what is the problem?

Regards
Siddharth
