Hi Luna
I am not sure why this question is still coming up. I am under the impression that git already includes my changes, which I believe already resolves buffering issues. I have no issues reading CK/IK commands (although I do recommend you to use your own parser as I think wireshark parser is very limited) on any 3G/4G sim cards.
You should be able to find a binary build of the changes I made in an earlier email I submited. However, do take note that the client application will have to be changed as well because additional fields had to be added to the usb packet header)
Best regards
