How to force the class of a device

[Frederic Praca]

Hello guys,
I recently bought a guitar multieffect device BOSS ME-25. It has a USB
interface which is used to transfer several settings between its memory
and the computer.
Off course, BOSS only delivers a program and a driver for Windows or
Mac but I also found a program for Linux.
The driver enables to use the ME-25 as a MIDI device but, dumping the
device description, the device class is vendor specific as shown below :
coruscant# usbconfig -u 1 -a 3 dump_device_desc
ugen1.3: <ME-25 BOSS> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

  bLength = 0x0012 
  bDescriptorType = 0x0001 
  bcdUSB = 0x0110 
  bDeviceClass = 0x00ff 
  bDeviceSubClass = 0x0000 
  bDeviceProtocol = 0x00ff 
  bMaxPacketSize0 = 0x0008 
  idVendor = 0x0582 
  idProduct = 0x0113 
  bcdDevice = 0x0100 
  iManufacturer = 0x0001  <BOSS>
  iProduct = 0x0002  <ME-25>
  iSerialNumber = 0x0000  <no string>
  bNumConfigurations = 0x0001 


Is there a way to attach the device to the uaudio driver to use it as
a MIDI device ? Well, is this as simple or not ? ;-)

Regards
Fred
PS: Il already added the device in the usbdevs file for "recognition"
