Title:
046d:c52b [ThinkPad L520] Logitech Unified Receiver very laggy
Status in “linux” package in Ubuntu:
Expired
Bug description:
Since upgrading to 13.10, my wireless Logitech keyboard and mouse have
been very laggy and quite unusable. The mouse barely moves or responds
most of the time, and the keyboard either ignores input or gets stuck
on a character, or sequence of characters, and repeats them
constantly. They were both working in 13.04.
