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

\-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!
