hi there,

i would like to connect a teensy 4 (in usb-midi mode) to an axoloti: http://www.axoloti.com
the axoloti has an usb-host port and should recognise usb-midi devices.

from the logs on the axoloti i can see that the teensy 4 is recognised correctly as a usb-midi device, but no midi events come into axoloti. the same sketch works just fine when the teensy 4 is connected to a laptop.

i strongly suspect the reason for this is, that the axoloti only supports usb-1 midi devices and teensy4 does not correctly switch to usb-1 midi mode.

i have posted a similar question in another topic before, but is it somehow possible to force teensy 4 into usb-1 midi mode? so that it uses only 64byte buffers and transmits only at 12mb and a host sees it as standard midi device.
