That's the problem with an online manual I guess, unless you download a copy of it at the point you order the car they can (and will) change the contents at any point and refer to it.
I think it's really sketchy that they're now saying that data-only USB hubs is "by design", when it's clearly due to the chip shortage. It's the same *sugar* as with the passenger side lumbar controls. I have read about someone buying the data-enabled USB hub and being told by Tesla that it was an "unauthorised modification" (??), even though it's the identical part fitted to cars earlier in the year.
Unfortunately it seems that new owners will have to both buy the part themselves and try and get Tesla to change the gateway configuration on their car to be "data enabled". The second part is the difficult part, and will depend on how flexible your SC is.. most people I suspect will get stonewalled with a "there is no retrofit available sir/madam" response.
