It looks like this is a defect in 15-R between the hms and X11.

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.
