Hi! Thanks for your work on this library.

I've been trying to get it to work with macOS and I haven't been able to receive anything. rx() always gives me an Err(Usb(NotFound)), while device_version() seems to work correctly.

This is the basic example I've tried running:

use hackrfone::{HackRfOne, RxMode, UnknownMode};

fn main() {
    let radio: HackRfOne<UnknownMode> = HackRfOne::new().unwrap();
    println!("{:?}", radio.device_version());

    let mut radio: HackRfOne<RxMode> = radio.into_rx_mode().unwrap();
    radio.rx().unwrap();
}

Which gives me this output:

Version(1, 0, 4)
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Usb(NotFound)', src/main.rs:8:16

I also tried your rx.rs example and got this:

Spawned sample thread
Sample thread disconnected
Shutting down sample thread
thread 'main' panicked at 'Failed to send exit event to sample thread: "SendError(..)"', src/main.rs:89:10

Have you encountered anything like this? Which platforms have you been able to test your library against?

I believe there's a typo here:

This should probably be Request::SetLnaGain, no?
