Hello all,

I'm currently trying to write a driver for the MOTU Midi Express XT. The problem I have is that the device has same idVendor and idProduct as the MOTU FastLane Quad MIDI Interface (for which already a driver exists in snd-usbmidi). If I do an lsusb, I see that the field iProduct identifies the device as a Midi Express XT. But I found no way of matching to iProduct in the usb_device_id structure. Is there a possibility to do so? Otherwise I'm thinking of patching snd-usbmidi in a way that it differentiates between the devices there.


Here the lsusb output:
Bus 004 Device 003: ID 07fd:0001 Mark of the Unicorn FastLane Quad MIDI Interface
