You might get more details if you post on the Linux USB mailing list  
(and mention a specific kernel version), but I think the blacklists  
are per-interface.

If not, you can detach the kernel drivers after-the-fact. libhid has a  
tool called "libhid-detach-device" which could be expanded to look at  
interfaces other than 0. The core functionality is in  
hid_force_open(), which calls the libusb function  
usb_detach_kernel_driver_np().
