These can be requests to sign transactions or messages. +##### Ledger Nano S + Node-hid (usb) + +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.
