Subject: Re: [PATCH 2/2] HID: hid-logitech: Add support for G29
Simon et al,
My logitech cordless mouse is not detected in linux-next
I have bisected the breakage to this patch,
commit 29fae1c85166ef525b8b6518e749295e0c9d1e20 in linux-next.

I can only guess that it is either now being misidentified (regression).
... or do I perhaps need to enable a different driver now???
Happy to help if I can.
