@hwk Ive moved this to its own topic as this comes up occasionally
(also the USB Midi Controllers thread, is not a place for 'requests')
as a side note... hub support not only requires firmware changes to support the hub. but also for axoloti to support multiple devices... e.g. current midi targets are fixed to DIN, usb device,usb host... but adding a hub means N devices could be attached to the host.
this raises some 'interesting' questions about configuration, since the UI does not currently know about the device connected to the axoloti... and even if it did, the devices you attach to axoloti could be different when you 'build' the patch vs when you run it.
so how you would configure it, becomes an interesting question.
(there are some existing cases, where this is already interesting - but multiple devices support via hubs would make it a more 'pressing' issue)
also... its worth highlighting, some midi hubs may already be supported....
these are hubs that present themselves as multiple midi ports, rather than multiple usb devices.
(I suspect dedicated midi hubs fall into this category, e.g. midi man midisport 2x2 but I don't have any to test with)
