I usually just grab a fast device (SSD), and a 'watch -n 0.5 lsusb -t' command. It is enough to quickly see what bandwidth the device connects with. I went through everything this way when my usb bin overflowed. Now I have a 2.0, and a 3.x bin and it is enough to quicky find what I want. For power testing I have a Plugable usb c meter, and a Uni-t UT658dual. Neither of these is very smart or standalone though. They are enough to see what voltage is negotiated and how much current is drawn.
