Hi Zoran,
Thanks for your support.
But I don't find /proc/bus/usb/devices node in my system.
And I think it has been deprecated.
So, as suggested by you I am going to try adding busybox to my system,
and creating the sda node manually.
Thanks & Regards,
Umakanta PAtro

Patro,
Please, check file /proc/bus/usb/devices and try to see if you have registered USB mass storage device there.
You can also use http://www.linux-usb.org/usbtree shell script which will browse for you devices and print the USB tree.

Subject: Fwd: Seeking support to get USB Host Interface (Mass Storage) working with Linux 2.6.35
Dear All,
Currently I am working on an AT91SAM9M260 based embedded board with linux 2.6.35 ported to it (With Android file system).
In this I am trying to use the USB Host port as a Mass storage function.
For this I have configured my kernel with the following configurations:
/CONFIG_USB_SUPPORT=y
CONFIG_USB_ARCH_HAS_HCD=y
CONFIG_USB_ARCH_HAS_OHCI=y
CONFIG_USB_ARCH_HAS_EHCI=y

And with this configuration when I plug in a Mass storage device, I get the following console message
*usb 1-2: new high speed USB device using atmel-ehci and address 2 usb
1-2: New USB device found, idVendor=0951, idProduct=1607 usb 1-2: New

This mass storage device is FAT32 formatted.But unfortunately, when I try to check for the /dev/sda1 I don't find any node created. Also with the USB debug messages enabled, I get so many messages stating "queuecommand called" repeatedly and at last stating no medium present.
The messages are being attached as a text file.
So, I will be very much thankful, if i find some support in resolving my issues.
Thanks& regards,
Umakanta Patro
