I will mention, if it is of any importance, that I get the following when the driver is loaded:

That looks like the MIDI interface. Do you have the MIDI ports (see "amidi -l")?
No MIDI ports show up. Nor are there any on the device or any that I'm aware of that are "internal" to the device.
I will note that on the Boss BR-80 there is an "internal" MIDI port which can be used as a drum synth. There appears to be nothing similar on the JS-8.
My original quirk actually had an bug as it included a MIDI endpoint definition. This originally worked without error, but in later versions it started to error in a similar way, I believe because of later changes to snd- usb.
From what I can tell, the JS-8 announces a MIDI-like interface, but doesn't
actually have one.
Is there any error message in the system log?
Not really. It's pretty uch the same as in dmesg:
