UI_a112 - USB device malfunction - I/O Error

[Flybyglass]

Well after almost 2 days of no errors, Sunday I had 5 UI_a112 notifications at various times and I only drove the car one. I think Tesla is waking to gather data athopugh my MY with AMD processor has n o UI_a112 messages. Same software.

The errors returned after about 2 days. Now continuing at odd times When overnight and asleep. Anyone find a solution yet or are we waiting for 2024.12.XX?

The only thing I've found is rebooting the infotainment system while driving and outside your home wifi. For some reason that works well until the car goes back to sleep when you return home.

No solution except if your car is 2022 or. Everhas usb-a in glovebox, use a hub to provide a few more ports

in my 2022 model y performance with mcu2 (intel atom cpu), the glovebox usb-a still works fine despite the error messages. I use a hub connected to that port to gain additional usb ports. The dashcam requires usb,3 speeds ( blue port) so be sure to use a hub that offers one usb-a with a blue port. A hub came with the abstract ocean led dash kit that I had bought.

FWIW my 2020 M3 had the 2 USB-A ports in the forward pedestal and intel processor. I get the Ui_a112 messages on waking. My 2022 MY with the glove box port and AMD processor with a 256gb Samsung flash gets no messages. Both cars have 2024.3.15.

Yes, I see the UI_a112 message in the notifications area.

I got 2024.3.25 today. It didn't fix it.

I have a 2020 MYP (center usb) & 2022 MYP (glove usb). Having issues on both not recognizing the drives after multiple formatting and hard reboots. Everytime the cars go to sleep it goes back to Not recognizing the drives!!!

received OTA updates for both 2020 MYP (center usb) and 2022 MYP (glovebox usb) yesterday. v11.1 ⁦(2024.3.25 5aaf7e6d2826)⁩ on both cars now. Problem is still continuing. The 2020 worked until the car went to sleep last night. Still not working on the 2022.

Definitely a software or firmware issue.

Bummer, my car is installing 2024.3.25 right now and I was hoping this would fix it.

I’ve already taken my car in twice for similar errors but, after a port change and new USB, was told a future update would fix the issue as it persisted. Annoying, especially as I’m continuing to get the errors:

Looks familiar and I'm now on 2024.3.25 and the issue continues. Some post mentioned to expect a fix with 2024.12.X. Center Console USB-A ports.

Same issue. Started about a month ago.

Using center console USB-C ports... they've worked flawlessly for 3yrs. Sounds like it's software related since I'm not alone here
