# embassy-usb-driver This crate contains the driver traits for [`embassy-usb`]. HAL/BSP crates can implement these traits to add support for using `embassy-usb` for a given chip/platform. The traits are kept in a separate crate so that breaking changes in the higher-level [`embassy-usb`] APIs don't cause a semver-major bump of this crate. This allows existing HALs/BSPs to be used with the newer `embassy-usb` without needing updates. If you're writing an application using USB, you should depend on the main [`embassy-usb`] crate instead of this one.
