the UPS isn't a PCI device. the USB channels on the motherboard are, 
however, thats what you see.

the UPS doesn't HAVE a PCI ID, its not on PCI, its on USB.
"Buss 001" means its on USB Controller 1, which is PCI ID 
(bus:slot.func): 00:1d.0
Use lspci -vn if you want to see the vendor/device codes are for 00:1d.0 
(probably be 8086:xxxx) instead of the symbolic names shown above.

00:1d.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI 
Controller #1 (rev 02)
