No USB data transfer on Pixel 3a

you have a passcode set
developer options are on, in settings
you have restarted the phone
you have the latest ADB and fastboot drivers installed

Is this happening on 16.04? If so, which OTA?

@MrT10001 I have a passcode (although I also have a fingerprint set up if that matters). Developer options are on. I have restarted the phone. On one of computers has adb 1.0.39 and the other has 1.0.41, and neither of them are able to see the phone while it's unlocked and plugged in (either with adb devices or in the normal file system). I'm still looking but I haven't been able to figure out how to check the fastboot driver version yet (or what the most recent version of adb is for that matter).

@etdoughe It is version 16.04 and OTA-25.

@lduboeuf Also, in case I wasn't clear about this, the USB data transer was working with Ubuntu Touch for a long time and then stopped.

@Exomnium I always install Android Studio to get the latest fastboot drivers and run a command prompt from the paltform-tools folder.

I had the same problem. USB transfer/recognition worked on 16.04 OTA 23, then when I upgraded to OTA 25, it did not (https://forums.ubports.com/post/73614). Then, I upgraded to Focal, and it works again. My recommendation, upgrade to Focal.

@Exomnium As mentioned by @etdoughe I would now make the move to Focal. Xenial is end of life and the Focal version for the 3a is really good, better than your current one.

@etdoughe I have the same problem (I have a Samsung S3 Neo with 16.04 on it). The moment I updated to OTA 25 no data transfer was possible anymore. Since I can't update to Focal, the S3 Neo hasn't been ported yet (or never will be ;)), I have a problem...

@bmlu I wonder what happened with the data transfer in OTA 25 But in any case, an alternative for file transfer is by using SSH/SFTP. Pretty easy if you have Linux on your desktop. On Windows, you can use WinSCP and similar apps.

@bmlu I have found that data transfer works on some S3 Neo's and not other after the update to OTA-25.

@bmlu Another way to access your data (that I used when I had the OTA-25 transfer issue) is:

@kugiigi In our local network at home, I always use the ssh connection to the phone (I have debian bookworm on my PC). The first time I noticed the problem after my update to OTA-25 was when I wanted to write a small clickable app for starting and stopping ssh: I found a tutorial to write clickable apps and there were promoted two ways to deploy the app, via usb or via ssh. I decided to use usb and voila, I noticed the problem ;).

@etdoughe Thank you for the link. I now can transfer data via usb using the recovery mode ;). Although I would prefer a OTA-26 release which fixes the usb issue ... or at least a patch or something, but you can't have everything ;).
