Asynchronous generators yielding detected hotplug events on the USB buses
Project description
aio-usb-hotplug
aio-usb-hotplug
is a Python library that provides asynchronous generators
yielding detected hotplug events on the USB buses.
Requires Python >= 3.7.
Works with asyncio
,
curio
and
trio
.
Installation
Use the package manager pip to install
aio-usb-hotplug
.
pip install aio-usb-hotplug
Usage
Dump all hotplug events related to a specific USB device
from aio_usb_hotplug import HotplugDetector from trio import run # ...or asyncio, or curio async def dump_events(): detector = HotplugDetector.for_device(vid="1050", pid="0407") async for event in detector.events(): print(repr(event)) trio.run(dump_events)
Run an async task for each USB device matching a VID/PID pair
from aio_usb_hotplug import HotplugDetector from trio import sleep_forever async def handle_device(device): print("Handling device:", repr(device)) try: # Do something meaningful with the device. The task gets cancelled # when the device is unplugged. await sleep_forever() finally: # Device unplugged or an exception happened print("Stopped handling device:", repr(device)) async def handle_detected_devices(): detector = HotplugDetector.for_device(vid="1050", pid="0407") await detector.run_for_each_device(handle_device) trio.run(handle_detected_devices)
