as I wrote - it happens with several different enclosures.

1 containing a dvd-rw drive
1 containing ide disks - tried two different disks in this one
1 from a friend containing an ide disk, working well with his systems.
1 from the same friend containing a 2,5" drive and a y-cable,

That are four different enclosures and 5 different drives that are 
problematic. I thought that it might be the 4 port hub, but if I disconnect it 
and put in the mouse receiver directly the same things are happening. I also 
tried different ports, it is always the same.
