ChangesADB device connection
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change adds automatic remote-device connection and explicit connection lifecycle methods. It is mergeable with owner awareness, but ADB failures may expose only generic diagnostics and timeout handling is not fully covered by regression tests. Possibly related PRs

connect_device and disconnect_device, catch subprocess.TimeoutExpired, and
preserve the driver’s existing failure behavior when ADB hangs. Add
driver_test.py coverage verifying the timeout path for these ADB connection
commands.

stripped response for 10.0.0.2:6520 rather than only checking for “connected”.

remote devices. In

109-130, update AdbServer.__post_init__ to read the optional device
configuration and call _connect_device after starting the server when

lines 86-90, add coverage for configured-device startup expecting the adb
connect subprocess call, while retaining the two-call assertion only for
no-device configuration.

Can you provide some examples on the README.md? I'd like to understand the use case and I think we should be careful with:
I am worried that for using this you need to discover the IP of the final device, then call connect with the host/port... ? |
I will add, this is meant to be used by the cuttlefish driver, where an ADB port is assigned and cuttlefish is remote (and has host set) |

- Around line 152-162: Add a test alongside test_disconnect_device_error that

the ADB server: accept only finite numeric values greater than zero, and raise
ConfigurationError for zero, negative, non-finite, or non-numeric inputs. Apply
this validation at the constructor or initialization path that consumes
connect_timeout, before any subprocess or ADB startup call.
In `@python/packages/jumpstarter-driver-adb/README.md`:
- Around line 152-158: Update the _connect method in the parent-driver example
so it does not broadly swallow Exception or falsely imply an automatic retry.
Catch only the expected ADB connection failure and either implement the stated
boot-wait retry explicitly or re-raise unexpected exceptions while preserving
the warning for recoverable failures.

disconnect_device() raises. Use the existing mock_run call assertions without
changing production behavior.
