Using docker mvt

What should I enter for <your_usb_port> in the command
<… device=/dev/<your_usb_port> mvt >?
I had entered the device and bus numbers listed for the device as seen after executing ‘lsusb’. But I received an error message <error gathering device information while adding custom device “/dev/003/003”: no such file or directory.
