Hello guys, I'm new to this community, currently I'm working on the release a new MIDI product that is a MIDI over BLE device. One of the product requirements is having a USB interface for USB MIDI controllers. So, having the previous requirements , I have the following questions:

1. Are there specifics characteristics for the USB controller?
2. When connecting the device to a USB host, let's say a PC, is there an specific USB controller that allows the device to be recognized as a MIDI device?
