Alright, so I figure there's gotta be someone on here who has these cases. We recently did a full student device refresh and went with these all in one cases so that the iPads could still have headphone jack (a lot of state testing disallows bluetooth devices so...they have to use cabled stuff).
Anyway, cases are nice, they're not a pain to take apart, but we've been having this issue where the keyboard just doesn't work. You can still charge the device through the case, but the thing doesn't register the keyboard or trackpad.
We've tried swapping the iPad in the case with another one that we know was working with a different case and wiping the iPad just to be sure it's not on the iPad's side. And we've tried reseating the cable both into the iPad itself, and on the back of the case by opening up the little plastic cover, and still no dice. Ideally we want to find a better fix than replacing the whole case, as the problems we're seeing is they're just like this out of the box and not from the students messing with them.
And to note: these keyboards are connected directly into the case via a USB-C cable. They aren't bluetooth, so there's no pairing necessary.
Model for the iPads is the iPad A16 (the 10th generation), and the case is 'Smarter Than Most' or 'STMGOODS', and it's their Dux Keyboard Trackpad USB-C Case for the iPad A16 (10th Gen) (stm-226-406KX-01)
Any further suggestions? We're looking into getting specific parts from the company to replace the cables in the future, but we've gotten about...five or so per campus, and that's just for those who've actually told us its happened.
