The enumeration varies by the stick type, and is naturally related to the router's OS, so Windows has no knowledge about Linux enumeration.
Example of trying three sticks in my MT6000 router:
(note "usbutils" installed for "lsusb" command, but the same info is in the system log, too.)
Old slow stick got 1:2 while new USB3 sticks got 2:1
root@router6000:~# opkg install usbutils
Installing usbutils (017-r1) to root...
