They told me that they were sending me the "V2" hub, but frankly I cannot tell whether there's any difference between the one that arrived last week and the one I originally bought in November 2020. There are no model number markings on these devices.
I'd asked whether this was a Version 2 of the hub for pre-June 2020 Teslas (that is, with two USB A ports). They didn't answer that question, so it may well be that V2 in their world actually means the hubs for later models, with one USB A and one USB C port. The replacement they sent me has two USB A ports, so it will fit (but not work properly in) my car.
While they've told you they've been in contact with Tesla, they've never answered that question when I put it to them ... and I've done so at least three times. In fact, I've corresponded at least a dozen times with them; between that and the many times connecting and disconnecting this hub, trying different devices in it, trying system resets and so on they've consumed enough of my time to be worth the price of about 20 hubs.
Of course, their warranty lists "updates" as a non-supported failure, so they have an out when it comes to refunds.
They also told me that they didn't have any of the V1 hubs to test. (I guess they prefer to have customers do their QC and R&D for them. I've never before heard of a technology company failing to keep even one sample of a product they've sold.) If V1 actually means hubs for pre-June 2020 cars, then they indeed do have those hubs to test ... they're still selling them to people.
Not very effective communicators, this company. They recently started sending out emails promoting their next product, a magnetic SSD. It'll be a cold day in hell ...
