Novation Launchpad isn't a regular midi device.
It is indeed a class compliant USB MIDI device.
Novation used interrupt rather than bulk for their endpoints. The USB audio class spec allows this, though it is a rather unusual choice.
The actual core of UHS3 is quite fast. I'd have to say if it acts that way across everything, then it is UHS3, else it is the t3.2 code.
If you care about this, hopefully this at least gives you a test case to look at the issue.... a test case where you actually have the source code for the device side!
