If the micro USB cable used by Innovv have some name like UC E6, they should write on their website something like UC E6 MicroUSB cable.
Also if they used a non standard connector, they must always be sure the buyer have all needed cables. Regarding charging, the camera can be charged with any of their 3 cables so if any of them will break sometime the camera can be charged by the other two.
Also the Innovv developer must assure his american and european partners always can sell one of these cables because the only real problem is the shipping time.
And as a camera developer is more easy for camera programming to have more pins. I think the Mobius developer already know this when programming a lot of firmware requests.
