Hi Andrew, A bug was opened against the Ubuntu kernel[0]. It was found that reverting the following commit resolved this bug: commit 8af6c08830b1ae114d1a8b548b1f8b056e068887 Author: Andrew de los Reyes <adlr@xxxxxxxxxxxx> Date: Mon Feb 18 09:20:23 2013 -0800 Revert "HID: Fix logitech-dj: missing Unifying device issue" The regression was introduced as of v3.10-rc1. Commit 8af6c08 reverts commit 5962640, so it seems commit 5962640 may still be needed. I see that you are the author of this patch, so I wanted to run this by you. I was thinking of requesting a revert for v3.11, but I wanted to get your feedback first.
