(12-04-2020, 09:08 AM)This is still a work in progress. We sent them detailed info and easy to follow instructions to configure a teensy microprocessor to show up identically via usb midi for their testing. I'll talk with Darryl later today and see if there's been any further word. Wrote: Jesse
I investigated this a bit further and ran tdd, an USB descriptor tool. This shows that the NDLRs Teensy is not configured as it should be (wrong USB interface type/class).
Here is the dump from the NDLR (i have marked missing and different information in red):

Sorry for the long posting. Hope this is of any help. Please note that a bootloader has its own descriptor data set, so it can be declared as mass storage or other class for uploading firmware etc. This is how several companies handle that. I can provoide bootloader USB readouts from my iConnectivity interfaces if these are of any interest.
