HID generic-bluetooth driver

Hi

I am currently working on a bluetooth HID device driver during GSoC
this summer and have a small problem. My dummy HID-driver does not get
bound on new devices. My dummy driver is available at:
https://github.com/dvdhrm/xwiimote/blob/master/driver/src/hid-nintendo.c

If a new bluetooth device with exactly these PID/VID values connects,
the generic-bluetooth HID driver gets bound instead of my hid-nintendo
driver. I checked /dev/hidrawX and it returns the same PID/VID values
as I specified in my driver so these are correct.
Also, if I use /sys/class/hid/drivers/generic-bluetooth/unbind and
.../nintendo/bind I can bind my driver manually to that device.

What can I do to lower the priority of generic-bluetooth or to push my
driver in front of generic-bluetooth?

Regards
David

Hi David,

 you can add it to hid_have_special_driver[] (drivers/hid/hid-core.c).

Thanks,

Since I cannot see any MODULE_DEVICE_TABLE() entry there, I guess I
can't extend this table on runtime?

Adding my device there helped. Thank you.

No you can't extend this table at runtime.

Adding my device there helped. Thank you.

You are welcome.

 happy hacking,
