Just as a comment, that many 'host controllers' looks odd.  From my rather 
voluminous usb tree:
[root at coyote nitros9]# cat /sys/bus/usb/devices/*/product
USB FAST SERIAL ADAPTER
HL-2140 series
USB HS SERIAL CONVERTER
Standard USB Hub
USB2.0 Hub
EPSON Scanner 010F
USB2.0 MFP(Hi-Speed)
BCM92046DG-CL1ROM
BCM2046B1
USB Receiver
Belkin UPS
EHCI Host Controller
OHCI Host Controller

Only one of each standard here.
