Andrew Svetlov <andrew.svet...@gmail.com> added the comment:

A task should have `await` inside to give to loop a chance to switch to another 
task (or get canceled).

It is not an asyncio bug but a part of specified behavior.

Your code could be modified as

async def readdev(dev):
    while True:
        buf=os.read(dev, 480)
        print([struct.unpack('llHHi', buf[i*24:(i+1)*24]) for i in 
range(len(buf)//24)])
        await asyncio.sleep(0)

to use tasks switching
