I get 'coroutine' error

D:\x\main.py:125: RuntimeWarning: coroutine 'list_devices' was never awaited
  devices = list(usbmux.list_devices())
RuntimeWarning: Enable tracemalloc to get the object allocation traceback
[ERROR] USB Error: 'coroutine' object is not iterable

tried with AI to fix things but it ends up not fetching 'books' UUID
not sure what's causing this

any insights?

ios 18.4.1
