Thid is still very experimental.
I only have 1 ledger nano, and testing is done locally (CirlceCI doesn't have ledgers plugged in ;)).
import { LedgerSigner } from "@ethersproject/hardware-wallets";
const signer = new LedgerSigner(provider, type, path);
// By default:
// - in node, type = "hid"
// - path is the default Ethereum path (i.e. `m/44'/60'/0'/0/0`)
