Hi All,

I am facing issues in enumerating USB mouse /Keyboard on my target
hardware.
My hardware and OS details are as below:

Hardware Davinci (DM6446)
OS WinCE 6.0

Problem description:

I have an internal hub IC on board. when i conenct mouse/KBD or mass
storage on the downstream port of internal hub i dont see any issues and
all devices work fine. Now i connect a self powered External hub to one of
the down stram ports of the on board hub. when i try connecting a mouse/KBD
to one of the downstream ports of the second hub i see that it fails to
enumerate. i opbserve that the SET_ADDRESS command fails as the host doen
not recieve any response from peripheral. 

I donot face any issues in mass storage when it is connected to second
level hub.

Also, i want to share another observation. If i coonect the external hub
and than power on my board the mouse/KBD gets enumerated without issues.ie
i am not facing issues when the external hub was connected prior to boot
up.

Please direct me if you have any clue or have faced similar issue ...

Thanks in advance ,
Anil
