Daniel Verkamp	6494117e17	usb: replace libusb with Rust usb_util library ... Drop the dependency on libusb and reimplement the host USB backend using usb_sys to wrap the Linux usbdevfs ioctls. This allows sandboxing to work without any dependency on libusb patches, and it gives us the flexibility to modify and update the USB backend without depending on an external third-party library.
