Hi!
Here's the "lsusb -v" for the Korg Pandora PX5D, attached. Hope this
helps.
The MIDI part of the descriptors is clearly marked as vendor specific, so there is nothing the driver can do about this, except for adding a quirk.
Assuming the MIDI interface is class compliant, the following patch should help. Can you give it a try?
For the Pandora PX5D, we also have to use the USB_DEVICE_VENDOR_SPEC macro, so the class compliant audio interfaces are not ignored by adding the quirk.
Daniel
A winner.

Huzzah! Please commit. your 8 character diff ;) oh. and you probably should change the 8R at the same time given it's essentially the same hardware with different analog bits. (8 pre's instead of 4)
