On Pixel 3, get "The connection to the adb bridge was closed, or preempted by another QCSuper instance"

[banshee]

When I run with a rooted Pixel 3 attached (running AOSP master), I get:

./qcsuper.py --adb --pcap-dump outputfile
43555
ioctl: Invalid argument

The connection to the adb bridge was closed, or preempted by another QCSuper instance

When I run strace /data/local/tmp/adb_bridge on the device, here's the last lines:

hello!, did you have any luck with this issue? I am actually experiencing mostly the same thing...

[banshee]

No, and ended up not pursuing it at all. Good luck!

Hello! Well I did go through, I updated Android to 7.0 (using normal OP3 system upgrade, nothing fancy) and rooted the device again... From then everything went smooth,

It works great! Cheers
