 I perform some experiments. Results is here.
 
 I. Test other mice .
 The 1st is
 ums0: <A4Tech RF USB Mouse, class 0/0, rev 1.10/0.01, addr 2> on uhub0
 ums0: 8 buttons and Z dir.
 
 and the 2nd is
 ums0: <Logitech Optical USB Mouse, class 0/0, rev 2.00/3.40, addr 2> on uhub0
 ums0: 3 buttons and Z dir.
 
 Bug still exist
 
 II. Test direct connection mouse without hub.
 
 Bug still exist.
 
 Resume: It's not mice or hub or connection-via-hub problem. (But it may be 
 some usb host problem)
 
 III. Hot plug out and plug in mouse in X environment
 
 After plug in mouse gehaviour BEGAN CONVENTIONAL. This can be recommended as 
 workaround. 
 
 Notice:
 1. After plug out mouse cursor may still disappeared. In this case you can 
 switch to VT0-VT7 terminals, move mouse and switch back to X session.
 2. This advice is provided 'as is' without any warranties of usefulness, 
 capacity to work with your hardware or software and other sorts of warranties.
 
 IV. After hot  X session restart (without OS and hardware restart) mouse still 
 work.
 
 V. Other cases:
 Hot plug out and plug in mouse in text mode environment before start X 
 session.
 Start OS mouseless and plug in mouse before or after start X session.
 Hot OS restart after my workaround appliing.
 
 In all this cases mouse behaviour was still buggy.
 
 I'll be glad if my info help to resolve this problem.
 
 Regards.
