[Pyusb-users] how to calculate correct Location ID

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

I want to display the Location ID for a device.

If I print dev.location I get a different location to that displayed in
OS X System Profiler (SP) and the ioreg command.

print hex(dev.location) gives me 0x1a000000, but ioreg and SP gives me
0x1a200000.

How do I calculate the correct Location ID for each device ??
I must have to add some offset or perform some calculation.

Thanks, Brendan.
