I can confirm that AKAI MIDImix works out of the box with no additional work needed for basic functionality.
Also, for those who don't know, attaching a USB HUB allows for a whole swath of devices recognized by the P3SA:
I've been using this one successfully: UGREEN USB Hub 3.0 Powered, 7 Ports

Attached devices:
Cable Matters 4-in-1 USB Hub with Ethernet (to bypass WiFi)
https://www.amazon.ca/gp/product/B073X6 ... UTF8&psc=1
iConnectivity Mio10 (yes the old one)

AKAI MIDImix
Launchpad Mini MK3
*Sadly, last I checked a few months ago, these did not work without additional configuration (that I've not been able to configure):
FaderFox EC4
KORG nanoKONTROL2 (my current favorite -why not?)
KORG nanoKEY2 (it does work routed through the USB IN of the Mio10)
AKAI LPD8 . . uhm, not sure. It was recognized but I think needed additional configuration.
Will test again with incoming firmware updates.
