This is a sign of a poorly designed driver. USB has to assign a device
number to the scanner, depending one which port it is connected. On a
proper USB driver, this number gets updated silently. The only way around
this is to disconnect the scanner and re-connect it to each USB port you may
have. This will force the device number to be assigned to each port for
whenever/wherever the scanner.
