Given the error symptoms it looks like we can enable to tracing in ADB to get it to tell more information about what is going on. Just set the environment variable ADB_TRACE to adb,transport for the job (or as a global environment variable in the jenkins configuration). You might need the EnvInject plugin installed to do this.

Now when the build runs it will log additional information in the console output. The ADB server will also log to /tmp/adb.log. That location is hardcoded and cannot be changed so you need to grab that after the build. Also make sure that you remove it before the next build or it will append the new log onto the end.

If it is configured right you will see lots of messages similar to the following:

system/core/adb/adb_client.c::_adb_connect():_adb_connect: return fd 3
system/core/adb/adb_client.c::adb_connect():adb_connect: return fd 3
system/core/adb/transport.c::readx():readx: fd=3 wanted=4
system/core/adb/transport.c::readx():readx: fd=3 wanted=4 got=4

I don't really think you need to capture the "good" logs anymore we have enough examples of that so you might as well save some uploading time.
