Research direction
Read the traceback entry points in electrum/gui/qt/wizard/wallet.py, electrum/plugins/hw_wallet/plugin.py, and electrum/plugins/ledger/ledger.py, then inspect ledger_bitcoin/client.py around get_extended_pubkey. Reproduce or trace the 0x5515 UnknownDeviceError during wallet setup; done means identifying the cause and preventing the wizard from crashing, with a regression check if an appropriate test location is found.
