Those messages all seem to be related to a hub. Vendor ID 0x0409 is NEC.

FTDI's vendor ID is 0x0403, and FTDI stuff works fine in FreeBSD 9 and
10; I use it all the time.  Sometimes aftermarket vendors who use FTDI's
parts program different vendor/product info and IDs have to be added to
code to recognize them, that's the only trouble one usually encounters.
