Hi there, nice to see that this topic raises an informed discussion. Thanks a lot for the enlightenment.
As for your question: > Is there a specific reason you would need root hubs to always have the > same address on a single platform, or across multiple platforms? For bandwidth sensitive applications in particular, knowing which devices are connected to a given host controller is an important information. The root hub is the only way to get there (when sticking to libusbx, at least). While information about the host controller itself is not accessible via libusbx, the root hub can be enumerated and queried for its VID/PID (which is identical to the HC make and model). Constructing a device tree (including manufacturer and device names) from the root is thus trivial when using the information returned by libusb_get_port_path(). I'd definitely deem it a valuable thing being able to retrieve this information in the same way on all supported operating systems BTW. All the best, /Markus ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
