What is a USB bus Linux?
Introduction to USB on Linux A Universal Serial Bus (USB) is used to connect a host, such as a PC or workstation, to a number of peripheral devices. USB uses a tree structure, with the host as the root (the system’s master), hubs as interior nodes, and peripherals as leaves (and slaves).

How do I read the bus sequence from the device tree?
You can read off the sequence from the device tree you get with lsusb -t. The number before the hyphen is the bus, the numbers after the hyphen are the port sequence. Your device is on bus 01, on port 1 of the root hub for this bus is another hub, and on port 3 of this hub is your device: So you get 1-1.3.
What is the driver ID for Raspberry Pi rt73usb?

Your device is on bus 01, on port 1 of the root hub for this bus is another hub, and on port 3 of this hub is your device: So you get 1-1.3. If you know the vendor id from lsusb (like 148f for Ralink), you can also grep for it with as answer.
