T520 information and whitelist removal request

I got a whitelist removed previously in a thread that people have stopped responding to on here and am looking for some help. I got a new Sierra Wireless MC7700 WWAN card and this laptop, regardless of OS, detects it on hotplug then proceeds to disable it completely within a few seconds. The problem cannot be reproduced on my netbook. I'm having a hard time figuring this out and wonder if when I had my previous whitelist removal request it might not have covered this card, so I was wondering, how it worked and if it could somehow be related to this issue. I'm now using a non-stock wlan and non-stock wwan card in the laptop.

Any information would be appreciated.
