Hi Greg,

Thank you very much for the help. I tried monitoring the packets with CATC
analyzer. There is no packet coming out of USB port. 

If I directly write a small routine to send USB SET ADDRESS packet to the
device, (Not on Linux) it is getting acknowledged correctly. (I did it to
check whether the H/W is ok) I am able to monitor the control packet in CATC
anlyzer. But the same is not happening on Linux.

The OHCI ED Control Head is loaded with physical address of the ED
Descriptor. 

How can we check whether the ED Memory is getting accessed by host
controller to send out "SET ADDRESS" packets.

Is the pci_alloc routines work fine on NON-PCI platforms or is there any
change required.

regards,
Nageswari

Heh, a USB protocol analyzer is probably the best way to determine this.
Or use the usbtest module and see if data gets sent back to you.

Good luck,
