USB MIDI interface does not work

[Harri T.]

Binary package hint: linux-image-2.6.27-3-rt

This version of the realtime kernel does not support USB MIDI interfaces. At least Yamaha UX-16 does not respond at all. It works fine with linux-image-2.6.24-21-rt or linux-image-2.6.27-7-generic.

OS: Ubuntu Studio 8.10
Package: linux-image-2.6.27-3-rt 2.6.27-3.8

That's odd: my MIDI devices (a m-audio keystation and a yamaha wx11 though a m-audio midisport 2x2) do work under linux-image-2.6.27-3-rt, but performance is *much* more jittery (to the point of being unplayable) compared to 2.6.24-19.

Haven't found a launchpad issue for this yet, but I'll search around a bit more before opening a new one.

I switched back to Hardy's rt kernel and the interface started to work again. See the post here:
