Can you please tell me how the ""USB Device Number" ist generated by the data from the USB device?
Using the LIST mode the devices are displayed and in the first column named "Device" is this number shown.

The number is assigned by Windows. At least until Windows 7 it was usually a 4 digit number, that remained assigned to the specific device, until you removed the entry for that USB device from the registry. Newer Windows versions (10) assign the next free number in ascending order. Removing a device causes re-enumeration for all devices.
