udevinfo prints all attributes in sections, you can select and combine
any attribute within _one_ section, thats why we print it all.
Unfortunally, I see this doesn't solve your problem.

could you please send a:

tree /sys/devices/pci0000:00/0000:00:1d.2/usb2/2-1

I want to have a look if we can do something for you :)

thanks,
Kay
