As one of the contributors of the original quirks (for the JS-8) , I thought I 
should test this on my device. I can report it appears to work well with no 
obvious regression.

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

[ 3339.994922] usb 1-6.2: new high-speed USB device number 8 using ehci-pci
[ 3340.089613] snd-usb-audio: probe of 1-6.2:1.2 failed with error -5
[ 3340.118610] Unable to change format on ep #84: already in use
[ 3340.118628] Unable to change format on ep #84: already in use
[ 3340.118719] Unable to change format on ep #84: already in use
[ 3340.118860] Unable to change format on ep #84: already in use
....

This appears to relate to EP 4 IN for Implicit feedback data. However, for all 
practical purposes the device seems to work beautifully for both recording and 
playback.

I have posted the lsusb output for this device below in case it is useful. I 
also have a Boss BR-10 which another of the devices related to this change. 
When I get a chance I will test with this also.

$ lsusb -v -d0582:0109
