USB ports not appearing when connected to iconnectivity Mio XL

[Bigsniff]

Curious what’s going on here. I have an Iconnectivity Mio Xl that has 10 USB host ports. It works great with any USB MIDI device I own except the NDLR, which is not being recognized when I connect it. The NDLR powers up when connected and works great but is not appearing as a USB device. I otherwise successfully have a keystep, cirklon (which appears as 6 USB devices), SQ1, microfreak, minilogue XD, Kordbot, SE engine, and more connected to these USB host ports. Any idea why the NDLR isn’t being recognized and what I can do to remedy it?
