[libhid-discuss] Preventing HID driver attachment

[Avishay Orpaz]

Hi
I have a device that exposes two interfaces - one HID and one mass storage. I would like to know if there is a way to prevent the attachment of a HID driver in linux. Is it possible to do so while keeping the other interface ability to be attached to its standard driver?

Thanks,
Avishay

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().
