Do you mean, it does not work? Or does the toggle remain greyed out (so tether never turns on)? On suzu the toggle turns on. Dmesg of my ubuntu box with suzu attached also shows that usb is connecting as a networking device:

it does not work however. Maybe we miss a property?

confirmed

jerpelea commented 6 years ago

it looks like this is an Android 7.1 bug and it requires code backport from Android 8

erikcas commented 6 years ago

really @jerpelea is it? Loire (and I think some people assumption is that I am running 3.10 but let me make sure again I am running suzu on k4.4 android-8.0) has it NOT working as I described above, which also was, again, on k4.4 android-8.0 suzu

Or did I miss a fix somewhere.

edit lol I see you reopened https://github.com/sonyxperiadev/bug_tracker/issues/24

jerpelea commented 6 years ago

bug also confirmed on suzu

jerpelea commented 6 years ago

to sumarize this is an Android 7.1 bug when kernel 4.4 is used and it requires code backport from Android 8 with the same kernel and device configuration the functionality is available Android 8.0
