Hi 

I have a Logitech LX710 Cordless Desktop

lsusb :
Bus 004 Device 002: ID 046d:c517 Logitech, Inc. LX710 Cordless Desktop Laser

The mouse is no more detected in the 4.4-rc1 kernel, the keyboard is as usual.

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.
