[Libusb-devel] libusb-1.0: exposing bus topology

[Daniel D. <ds...@ge...>]

Hi,

Does anyone have opinions on how libusb-1.0 should expose device/bus 
topology?

In libusb-0.1, buses are a first class citizen. Scanning for devices 
involves iterating over buses.

In the current libusb-1.0, device enumeration is done by iterating over 
a flat list of devices. There is no exposed information about buses (but 
this can change). libusb_get_device_list() is the function in question.

Does anyone know of any libusb-0.1 apps which make use of bus topology 
information? I can't think of any obvious uses, hence my current design 
of ignoring them for device enumeration purposes. But I guess there may 
be value in some kind of "OK, I have a device, what bus is it on?" 
functionality. Any thoughts?

Daniel
