We have looked into the UAS revision-2 document and modified the code accordingly. Thanks for the advice, as we had failed to notice it Please find the latest usbmon output after the modifications. The CDB is 16 bytes and starts at 16th location. The TAG and Length filed are big endian format. However, there is no luck. Still I am getting the same errors. Could you please suggest me, if I am missing any thing. Thanks, Aditya.
