[Pyusb-users] Correct Location ID for USB device

[Brendan S. (eTRIX) <Bre...@eT...>]

I'm using PyUSB to obtain USB info, but the Location ID I get for my
device is different to what "System Profiler" and "ioreg" shows me.

eg.
    SP and ioreg show Location ID 0x1a200000
    pyusb: dev.location returns 0x1a000000

There seems to be some kind of offset, so I presume I need to
"calculate" the offset but I'm not entirely sure how or what needs to be
added.

Any one used PyUSB to find the Location ID of a device on OS X (or any
other OS) ???

Thanks, Brendan.
