Hi,
Is it possible to retrieve USB bus topology with PyUSB ?
Yes, you will need to use the Device object "port_number" and "bus" properties.
While it is enough for my application, I don't see how to reconstruct
the USB tree with just "port_number".
There's also "port_numbers", assuming you're using a somewhat recent
libusb-1.0 version as your backend. Combine that with the bus attribute,
and you can get a representation of the physical attachment point of the
device.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
