libusb1

libusb1 is a pure-Python wrapper for the `libusb-1.0` C library, providing low-level access to USB devices. It exposes both synchronous and asynchronous APIs, allowing access to all USB transfer types (control, bulk, interrupt, isochronous). Unlike PyUSB, which aims for a common subset across various USB libraries, libusb1 focuses on making the entire `libusb-1.0` API available. The project is actively maintained, with regular releases addressing bug fixes and improvements, such as the recent 3.3.1 release.
