Hi,

thanks for your reply, but i don't get it (i use calibre-debug -e):

scanner = DeviceScanner()
scanner.scan()
device = KOBOTOUCH(None)
device.open(scanner.devices)

I get same problem

  File "/usr/lib/calibre/calibre/devices/usbms/device.py", line 504, in find_device_nodes
    detected_device = self.detected_device
                      ^^^^^^^^^^^^^^^^^^^^
AttributeError: 'KOBOTOUCH' object has no attribute 'detected_device'
