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:

import Eth from '@ledgerhq/hw-app-eth';
import TransportNodeHid from '@ledgerhq/hw-transport-node-hid';
async function ledgerEthereumNodeJsClientFactoryAsync(): Promise<LedgerEthereumClient> {
    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,
});
