That's interesting: I have never had to unplug/replug, so I can't offer any insight on this. Was this consistent across more than one device (did you test another USB drive)?
Oh heck yes. I used to develop a version of Linux that runs from a usb stick so I have dozens of usb sticks lying around. Also, this is a known issue. Tesla (or Elon) said they have a software bug that can prevent usb devices from mounting. I think they made this a high priority because it can affect the TeslaCam functionality.
I used to have a lot of trouble with usb sticks plugged into a hub in the center console. AFAIK I never had a problem with the TeslaCam device in the glove box but I did not explicitly test it.
Here is a (not great) article about it from late May:
Elon Musk: Tesla ‘Dashcam Unavailable’ Bug Fix is Coming
Elon said that a patch to "filesystem driver fixes" the whole dash cam and Sentry Mode mess. The CEO adds that an update will see the light of day soon. Here's the Tweet:
Problem arose from optimizing application performance. Use of Linux page cache caused increasing memory fragmentation, eventually preventing mounting of dashcam. Patch to filesystem driver fixes this. Update coming soon.
A little set-back for me. After many attempts (including a couple of Touch Screen resets), I finally had to open a ticket today to have them reset my download as it was stuck at around 50%. So, nothing to report yet as I am still on 2022.12.3.16
That's a bummer. It's cool they can fix it OTA. BTW: Mine got updated to 2022.16.1.2 today. The release notes are the same as 16.1.1 so I imagine it's just an unspecified bug fix.
