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 -----Original Message----- From: Greg KH [mailto:[EMAIL PROTECTED]] Sent: Tuesday, December 31, 2002 11:25 AM To: Nageswari S Cc: [EMAIL PROTECTED] Subject: Re: [linux-usb-devel] USB Host Controller Driver ppc405 On Tue, Dec 31, 2002 at 09:21:34AM +0530, Nageswari S wrote: > > I do not have any debugger with me.

Or use the usbtest module and see if data gets sent back to you.
