This mouse shows a slightly different behavior, it also does not work initially but it did not come back successf= ully after the re-plug event (the USB LEDs were working though). There is no cur= sor movement on the desktop. This deviates from the initial Sharkoon Light 2 100 mouse that did come back successfully after a re-plug event. --=20 You may reply to this email to add a comment.
