By default, node-hid transport support is an optional dependency. This is due to the requirement of native usb developer packages on the host system. If these aren't installed the entire `npm install` fails. We also no longer export node-hid transport client factories. To re-create this see our integration tests or follow the example below: ```typescript import Eth from '@ledgerhq/hw-app-eth'; import TransportNodeHid from '@ledgerhq/hw-transport-node-hid'; async function ledgerEthereumNodeJsClientFactoryAsync(): Promise { const ledgerConnection = await TransportNodeHid.create(); const ledgerEthClient = new Eth(ledgerConnection); return ledgerEthClient; } // Create a LedgerSubprovider with the node-hid transport ledgerSubprovider = new LedgerSubprovider({ networkId, ledgerEthereumClientFactoryAsync: ledgerEthereumNodeJsClientFactoryAsync, }); ```
