adding a mains usb hub to server

im trying to add my new mains hub to my oscam server but when i plug my smargo reader into any of the slots the reader isnt found? i think it may be down to the address of my current usb port which is 002:002 so if i plug in a 6 way hub does anyone know what the address would be of these new usb ports?

ok folks got it sorted so listen up. whenever i plugged my reader into the new hub it had a new address, so my reader plugged into the new hub i ran lsusb in putty/terminal. this then displayed all devices connected and on the list i found my smargo on 001:004. then goto usr/local/etc and in oscam.server change your current usb port to the new port and all done.

now my cccam ecms are coming in at 0.0955ms whereas before i was getting 0.150ms
oscam is now 90ms whereas it was 150 before!

well chuffed :)
