After reverting the small diff between kernel 4.3 - 4.4-rc1 in drivers/hid/hid-lg.c an recompiling, it works again

Hi 

The bug is still present in the 4.4-rc2 kernel
Comment 2 Benjamin Tissoires 2015-11-30 09:27:35 UTC 
Created attachment 195991 [details]
0001-HID-lg-restrict-filtering-out-of-first-interface-to-.patch

Looks like 29fae1c85 ("HID: logitech: Add support for G29") was a little
bit aggressive.

Can you give a test on the attached patch?
I'll send it upstream when I get your tested-by.
