Immediately modified it and applied. Glad to say that it works. I had iperf running for an hour with no problem and 48.7GBytes of transfer at 116MBits/sec :). Going to run a longer 3 hour iperf test now, but, I guess it should be fine. I will spin a combination patch of what Peter and Matthieu gave me and try sending it by today evening for me, before going on vacation. Thanks a lot Matthieu, Peter and Felipe for the inputs and help. -Cheers, Sanchayan. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
