I'm trying madfuload under an i386 kernel and get the following:

lsusb
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 003: ID 0763:2805 Midiman
Bus 002 Device 002: ID 046d:c50b Logitech, Inc.
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 004: ID 0781:0621 SanDisk Corp.
Bus 001 Device 001: ID 0000:0000

./madfuload -D /proc/bus/usb/002/003 -f ma005101.bin -3 -v
ma005101.bin: 5959 bytes read successfully
reading device descriptor ...
interface descriptor 0:0
DFU interface is 0
DFU descriptor found
transfer size is 64
control transfer failed: (2) No such file or directory
control transfer failed: (2) No such file or directory
control transfer failed: (2) No such file or directory
downloading block 1 failed

and the kernel jabbers:
usb 2-2: usbfs: process 1949 (madfuload) did not claim interface 1
before use
usb 2-2: usbfs: process 1949 (madfuload) did not claim interface 1
before use
usb 2-2: usbfs: process 1949 (madfuload) did not claim interface 1
before use

Thanks,
