Hey, I posted this elsewhere, posting it here too in case it helps anyone (
@DrDabbles). My only question is, now that it has been resolved, do I dare try a hub again? (Was using
Sabrent 4-port usb 3.0, switched to
Taptes shortly after my USB woes started in early 2021.) Anyway, here you go…
Happened to me. Also, fsdBeta bricked my AP with 10.4 download on 11/7/21. Mobile service replaced the USB hub, it failed again the very next drive cycle (said there was nothing they could do for the AP since it was on Beta). Multiple updates later; no software fix. Got it into the SC; motherboard not talking to the daughter board — new MCU. Tesla said the three are not related (USB malfunctions, fsdBeta/AP malfunction, MCU malfunction) but that replacing the MCU fixed all three (which sounds like they’re all the same issue to me…).
I do have a theory, not that it’s based on much; Tesla was seeing hardware failures (or the potential for them) on early builds. They introduced firmware updates early 2021 to trip out the computer to protect itself, but some of us had computers that were already damaged. They don’t want a lot of people figuring this out under warranty. Just speculation, but it jives with my experience.
