Great responses mikedt & svim and as well the final procedure would to make sure that if your Pc has samsung Kies you might want to go ahead and uninstall it,maybe try and installing pdanet on both your device and on you windows Pc.
I just have one last question I didn't ask in the previous entry,why in fact areyou running odin on your device,is it to update,or is it to root it,or is it to put a stock rom on it to try and repair a problem?
Please be truthful,I'm not here to judge,only that the answer will only help get a better idea of the situation and better be able to help solve your technical malfunction.
