USB power after 2020.16.2.1 update

USB power after 2020.16.2.1 update

Before 2020.16.2.1, I believe, power to the USB in the front was turned off a few minutes after the console went dark.
I noticed that after this release, the USBs remain powered even after the car is parked for hours with no one inside.
I use an SD card reader that has an LED and the LED remains on all the time. Sentry is off.

If you have installed this version, can you confirm this behavior?

My 500GB Samsung T5 SSD FAT32 formatted used for Sentry mode is no longer recognized by firmware 2020.16.2.1 update. The new menu to format is grey out also. What do I do now? As far as USB power remain on, I can confirm that it is on now too.

Have you guys done a deep reboot with nothing in the USB ports? I have never trusted a reboot while a device is in a USB port. Most computers have some difficulty rebooting with a USB device plugged into the port. Remember a deep reboot requires you press the brake and scroll wheels until the T reappears on the screen.

@Anthony: USBs don’t cause problems for either computers or your Tesla unless the USB itself is bootable. It wouldn’t be unless you formatted it that way. I’ve never had a problem rebooting my cars with both music and dashcam USB drives inserted.

I thought the change to keep the USB power on happened quite a while ago, possibly to support Sentry Mode, but I’m not sure.

I recently removed my USB drive and now only plug it in when I want to listen to music on it (usually only when in internet dead zones which is not very often).

I read somewhere (TMC?) that every time you start the car, it re-indexes all the files on the USB drive and that eats into eMMC life. So fool me once, shame on me...

@barrykmd - Yes, every time you plug in your USB, it will re-index the music. If you leave it plugged in, it only re-indexes when you reboot - so far less often than plugging it in and out every time. Also indexing uses dramatically less memory nowadays, since they got rid of storing every album cover in flash memory with V10. Now covers are only loaded when you select a song and that's likely done in RAM.

TT - good to know. Thanks.

As far as I know with our 2015 S 70D, USB has always been hot. Evidence is an LED staying lit on the flash drive.

While we're discussing the USB, should you remove the teslacam usb drive before doing a software update? ie., can the updating process damage the drive?

TeslaTap.com | 2020年5月22日

No, the updating will not harm the drive. There are rare cases where people have a bootable drive and/or a bootable virus on the USB drive that can stop the Tesla boot process if left in during a reboot. This is rare, but a few have run into this. The cases with a boot virus will not infect your car, as they are designed to infect Windows/Mac systems.

I took the download and installed it with a 128 gb usb drive plugged in. The usb wasn't recognized on boot up it just froze in loading. A two scroll wheel plus brake pressed reboot with the usb unplugged allowed the drive to be loaded after the hard reboot.
The software looks the same as its precursor so it probably is a bug fix update.

Interesting. My upgrade to 2020.16.2.1 modifies the Tesla Toybox, Nearby Charging Sites, and provides Backgammon Improvements. Plus whatever hidden bugs repairs are included.

Ooh, backgammon improvements. Such a great use of resources!
