[SOLVED] How to detect USB on Raspberry Pi and access it using Python?

How to detect USB on Raspberry Pi and access it using Python?

I want to detect USB on Raspberry Pi and access USB to copy some data. I used pyudev and get some info from USB but I can't access it. What should I do? This is my code:

import pyudev
context = pyudev.Context()
for device in context.list_devices(subsystem='block', DEVTYPE='disk'):
    for props in device.properties:
        if device.get("ID_BUS") == "usb":
            print(props, device.get(props))

The path of the USB is /media/pi/CCCOMA_X64FRE_EN-GB_DV9 but I don't find it in list properties, when I print them out. How can I fix it? Thanks.

Solution

The reason that you can't find the mount point of the usb drive is that device.properties doesn't include the mount point. You could however get the disk name (/dev/sdx) from device.properties and then use subprocess.check_output(['findmnt', '/dev/sdx1', '-no', 'TARGET']) you can find your mount point in the return of this function.
