executing your cmd, I get :

nov 04 12:03:07 kernel: usb 1-1: Product: USB 2.0 Hub [MTT]
nov 04 12:03:07 kernel: usb 1-2: Product: USB 2.0 Hub [MTT]
nov 04 12:03:07 kernel: usb 1-9: Product: USB OPTICAL MOUSE
nov 04 12:03:07 kernel: usb 1-10: Product: USB Keyboard
nov 04 13:32:17 kernel: usb 1-6: Product: Mobilebroadband
nov 04 13:32:19 kernel: usb 1-6: Product: Mobilebroadband

the Mobile broadband was not connected during boot, though.

And the other two are simply passive port multipliers
(empty, no device connected), that have been there for long
years w/o causing any problem with no distro.

dunno why 1-6 channel is listed twice.
