Description
Trying to do integrity check of Ledger nano s plus using guide https://support.ledger.com/hc/en-us/articles/4404382029329-Check-hardware-integrity?support=true, since using ledger live app doesn't do check before you put private keys in the device
Command failes
$ python3 -m ledgerblue.checkGenuineRemote --targetId 0x33000004

Research direction
Reproduce python3 -m ledgerblue.checkGenuineRemote --targetId 0x33000004 on macOS and inspect ledgerblue/checkGenuineRemote.py around line 79, where the WebSocket response is received. Compare the connection and response handling with the command's expected integrity-check flow. Done means the command completes successfully on macOS instead of raising WebSocketConnectionClosedException.
