3G Dongles and UDEV Network Interface Issues

Hi guys,

i have 3 usb dongles, all having the same mac/device information.

When I connect them to my Ubuntu 16.04 all are detected when using lsusb.

However, only 1 device receives a predictably named network interface, the rest, are assigned names like rename2 and are not in the up state and neither do they have their USB modem IP address.

I can rename, bring up and assign the addresses using IFConfig but this is no good at all.

I reluctant to dig into udev without knowing if that is the right place to start, but really though the same udev rules are matched for every device so that is a meh.

Any direction / input is appreciated, thanks guys

Also Im considering disabling auto mounting and putting together a manual mounting script, would this be feasible and what tech is used to achieve this?

Here is a link to my askubuntu question with an image to assist you in seeing what I see on my screen:

This, to me, is the key to it. If the three of them have the same mac address, you've got to fix that. Mac addresses should be unique.
There's also the driver question: Can the driver handle three devices simultaneously? Maybe email the author. We wouldn't know because you gave us no information. So you do the hard work.

Device information is less critical, unless they're all saying "I need this IP real bad." They all get landed on different device adresses. To be sure, bring up the network with one, link them all in (one out, check it doesn't show, insert another) and check lsusb for the mac address of each one.

If they're usb wifi things, there just may be a current issue as well, depending on your ports.
