How does one do this? For example:

# lspci | grep USB
00:1a.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 02)
00:1a.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 02)
00:1a.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 02)
00:1a.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 02)
00:1d.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 02)
00:1d.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 02)
00:1d.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 02)
00:1d.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 02)

and

# lsusb
Bus 001 Device 001: ID 0000:0000
Bus 001 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply
Bus 004 Device 001: ID 0000:0000
Bus 005 Device 001: ID 0000:0000
Bus 007 Device 001: ID 0000:0000
Bus 008 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 006 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000

I thought an lspci -tv would help, but it doesn't show the UPS?

# lspci -tv
-[0000:00]-+-00.0  Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller
           +-02.0  Intel Corporation 82G33/G31 Express Integrated Graphics Controller
           +-1a.0  Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4
           +-1a.1  Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5
           +-1a.2  Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6
           +-1a.7  Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2
           +-1c.0-[0000:03]----00.0  LSI Logic / Symbios Logic MegaRAID SAS 1078

           +-1d.1  Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2
           +-1d.2  Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3
           +-1d.7  Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1
           +-1e.0-[0000:04]--+-00.0  Intel Corporation 82540EM Gigabit Ethernet Controller
           |                 \-02.0  VIA Technologies, Inc. IEEE 1394 Host Controller
           +-1f.0  Intel Corporation 82801IB (ICH9) LPC Interface Controller
           \-1f.3  Intel Corporation 82801I (ICH9 Family) SMBus Controller


So how do I know which controller has this device on it so I can enumerate the PCI ID of that controller?
Thanks!
