Yup, fresh out of the factory on Tesla's latest and greatest and the UI_a112 notifications started spewing out. I have scheduled a SC appointment just so I can get this issue logged in their books but based on what everyone has said there's no point in 1) swapping flash drive 2) changing the USB hub 3) changing the MCU. Will just have to wait for the SW fix.
Replacing the computer worked for at least one person:
My USB-A wasn't recognized, and the format and delete options were grayed out. I tested the USB on my computer, it worked perfectly fine. Tesla verified that there was an issue and replaced the computer (1684435-S0-1). Works fine now and sentry is working.
I've mentioned before that Tesla almost certainly uses different usb controller chips in different vehicles and even in the same vehicle. Each controller chip can use a different software driver. If one of the drivers is bad the problem can affect some cars and not others. I'm one of the people who has a consistently working glovebox usb port but a non-working center console usb port.
It seems at least possible that the service center will be able to fix the problem for you by swapping hardware.
