Hi @twt--,

I managed to make it work by using the following Provider:

const Web3 = require('web3');
const {LedgerSubprovider, Web3ProviderEngine } = require('@0x/subproviders');
const ProviderSubprovider = require('web3-provider-engine/subproviders/provider');
const Eth = require('@ledgerhq/hw-app-eth').default;
const TransportNodeHid = require('@ledgerhq/hw-transport-node-hid').default;

async function ledgerEthereumNodeJsClientFactoryAsync() {
    const ledgerConnection = await TransportNodeHid.create();
    const ledgerEthClient = new Eth(ledgerConnection);
    return ledgerEthClient;
}

class LedgerProvider extends Web3ProviderEngine {
    constructor(options, url, headers, debug) {
        super();

        this.addProvider(new LedgerSubprovider({
            baseDerivationPath: options.derivationPath,
            networkId: options.networkId,
            accountFetchingConfigs: {
                shouldAskForOnDeviceConfirmation: true,
            },
            ledgerEthereumClientFactoryAsync: ledgerEthereumNodeJsClientFactoryAsync,
        }));

        const web3Provider = new Web3.providers.HttpProvider(url, {headers, keepAlive: false});
        web3Provider.sendAsync = web3Provider.send;
        this.addProvider(new ProviderSubprovider(web3Provider));

        this.start();
    }

    send(...args) {
        return this.sendAsync(...args);
    }

}

And by using the exact following versions (truffle version is important):

        "truffle": "5.0.18",
        "web3-provider-engine": "15.0.7",
        "@ledgerhq/hw-transport-node-hid": "5.13.1",
        "@ledgerhq/web3-subprovider": "5.14.0",
        "@ledgerhq/hw-app-eth": "5.14.0",
        "@0x/subproviders": "6.0.8"

I am not quite sure why this comment was extracted to another issue. Sorry but this seems spammy, so I'm inclined to close this. Let me know if you think otherwise.
