Hey MultiBand
There are a whole heap of dongles tested and supported for controllers, RAPs, IAPs, etc.
Painfully, I can't find the public list at the moment; you're right that it's not in the interop page. I'm not part of the US, but I know the Huawei 3372s are supported on 8.1.0 and 6.5.1.0 and above on a 7005 off the top of my head.
Let me know what region and Controller version (6.x or 8.x) and I'll do some digging through my notes. Otherwise, the TAC is always helpful.
Cheers
Grocke
