This is surprising because the first thing option_probe() does is:
/* Never bind to the CD-Rom emulation interface */
if (iface_desc->bInterfaceClass == 0x08)
return -ENODEV;
so it shouldn't ever bind to any storage functions. Unless it is a
vendor specific storage function, of course...

Does this mean that intf #2 is actually a storage function using
ff/ff/ff class codes?
