Hi Denys,
Thanks for the help.
The lsusb -v told me that lsusb could not find usbfs. The log messages also did not have usb related messages. So, I regenerated the images after using 'bitbake virtual/kernel -c menuconfig' to add USB MSC support. I checked the log and lsusb -v. I still see the same error.
I have added the log and the lsusb -v below. Do you have any more suggestions on what I can do?
Thanks,
Sarvesh
