Hi,
I'm trying to use pyusb in a container but it has problem connecting to
libusb.
In the container, libusb is installed using "RUN apt-get install -y
libusb-1.0-0-dev"
and I'm trying this simple code:
import usb.core
import usb.util
def main(args=None):
#open()
usb.core.find()
I then get this error message:
python_1 | 2017-12-19 13:58:20,475

Any idea what might cause the problem?
