It is the same. Just this:

-------------------------------------------------------------------------
ugen0.2: <vendor 0x04cc> at usbus0
uhub4: <vendor 0x04cc product 0x1122, class 9/0, rev 1.10/1.10, addr 2>
on usbus0
uhub4: 2 ports with 2 removable, self powered
ugen0.3: <Western Digital> at usbus0
umass0: <Western Digital External HDD, class 0/0, rev 2.00/1.75, addr 3>
on usbus0
umass0:  SCSI over Bulk-Only; quirks = 0x0000
umass0:0:0:-1: Attached to scbus0
-------------------------------------------------------------------------
