Hi there, in case you are using Etcher on mac, you might find useful this thread: [Etcher doesnt recognize USB drive · Issue #1969 · balena-io/etcher · GitHub](https://github.com/balena-io/etcher/issues/1969)  
Could you please give me more context regarding:

- The Etcher version you’re running.
- The operating system you’re running Etcher in.
- Is your USB detectable from your operating system?
