You could skip the USB host option and get a raspberry pi 3 or higher (I've seen used for 5-20 bucks online) pi zero is 15.00 new (doesn't have full size ports)
 
	 
 
	With the pi you have a full computer. You can route midi between USB, record audio, play or stream audio, use a sequencer, control the amp wirelessly. Possibilities are endless.
 
	 
 
	I purchased the 100 for the midi in, but the 60 would of been fine. 
 
	 
 
	The midi in is only a midi in (for controllers)
 
	 
 
	The USB is an
 
	Audio input,
 
	Audio output,
 
	Midi in, & Midi out for setting dumps
 
	 
 
	Linux alsa (default sound system) can route midi with one command no extra software needed.
 
	aconnect -l
 
	Shows u device numbers on system
 
	aconnect <device from> <device to>
 
	Have it issue the command on start and your done
