The list of supported USB modems https://wiki.mikrotik.com/wiki/Manual:Peripheralsis a little vague when it comes to the Huawei E3372.
I bought a E3372h-320 which doesn't work on v6 (okay v7). Some E3372 work because I've got a locked BT USB modem that reports as E3372 and works fine. The notes do mention that not all work under RouterOS and then mentions cdc_ecm and serial only work. How do you equate this is the model names??
Same question about the Huawei E8372 which says "Works! LTE only". So will any E8372 work?
