    I have three Galaxy S3 phones, two SGH-I747M (Android 4.0.4) and one SGH-I747(4.1.1).
    When connected to my PC (Windows7), only one out of the SGH-I747M shows up under Device Manger's "Ports (COM & LPT)" while the other two show up under Device Manager's "Portable devices" as can be seen from bellow snapshot:

    S3 not showing under Device Manger's "Ports (COM & LPT)"  hardware type-devicemanager_samsungphones.png

    I need for all the phones to show up under Device Manger's "Ports (COM & LPT)".

    I have installed Kies thinking that it had to do with some missing USB serial Port driver but that still didn't resolve the issue. Also called Samsung and they did't offer any help, all they said was that the other Phones are reporting themselves as mobile devices to the PC.

    Appreciate any help resolving this issue.

    In talking with others, it's either a driver issue or something to do with Kies. Probably Kies, but it really could go either way. Even though the models are different and the same, something is getting confused. TBH I'd expect them all to show up as mobile devices and not in ports.
    What end are you trying to achieve? Perhaps that could shed some light on a fix.

    When you plug the phones in, do they connect as MTP devices or as PTP? Are they all the same?

    Thanks Scott for your reply, I have a software that is used for RF drive testing (Tems), and in order for it communicate with these devices they have to first appear in the Device Manger under "Ports (COM & LPT)" hardware type, otherwise the software will not see them. As for Kies, I think it has no connection to the issue because I was seeing the issue prior to installing Kies and I have only installed Kies thinking that it will resolve my issue when it updates the drivers but that didn't happen and the issue is still there.

    Got it. I'd assume it's a driver issue then. Try to reinstall drivers or roll back to a previous version.
