Thanks @jbn858273! I tried but I have simply the same issue, that the device is still not recognizing the USB drives. I tried again with several drives but none of them will work.
I'm confused that no USB drive will recognized. Even before the update it was impossible to upgrade. CarPlay with cable plugged worked, so the USB port is not really faulty I think.
