I further installed Current snapshot and 16 snapshot; 15 snapshot has the same issue as 15.0-R, but 16.0 snapshot work flawless. Both has the same input/event[6-9] for 2.4G Receiver, and moused in both snapshots use the same parameters. hms.ko is loaded by default. The wireless mouse works on the text console in 15.0-R, but when Xwindow starts, the mouse no longer works.home | help
