Comment 9 for bug 1385113

"Me too" here, except with Logitech DiNovo Edge mouse+keyboard combo. The keyboard stops working while mouse works and "unknown main item tag 0x0" is found in the log.

#1410699 and #1442896 are probably related or duplicate.

This used to work until end of summer 2015. I don't know an exact date. Running Ubuntu 15.04.
