Determining "com port on pc" for usb device

[maybeoneday]

Hi all

I'm trying to create a gsd device template, but failing at the first hurdle.

the device shows up in dmesg as

....................using ehci_hcd and address 8
       ............usb-0000:00:04.1-3.3

so the question is  how to use that info to give the template something meaningfull to system ?

is it to use Location onPCI bus parameter ?

tia,
Ian
