bose-dfu | Firmware updater for various Bose devices

If you already have a Rust toolchain installed on your computer, installing bose-dfu is as simple as running cargo install bose-dfu. To get a Rust toolchain, you can use [rustup](https://rustup.rs/) or install rust using your system’s package manager. Alternatively, you can find prebuilt binaries for Linux, Windows, and macOS on the [releases](https://github.com/tchebb/bose-dfu/releases) page. If you use Linux and encounter permission errors or see INVALID in the output of bose-dfu list, you likely need to give your user permission to access Bose HID devices. You can do this by copying 70-bose-dfu.rules into /etc/udev/rules.d/ and reconnecting the device (no reboot needed). If your device is untested, it won’t have an entry in that file so you’ll need to add one yourself.
