Re: USB: ums driver no longer detects Logitech mouse

More info. If I plug out the mouse and then plug in it again, it detected 
normally as:
ums0: <Logitech USB Gaming Mouse, class 0/0, rev 2.00/49.00, addr 2> on uhub2
ums0: 16 buttons and Z dir.
uhid0: <Logitech USB Gaming Mouse, class 0/0, rev 2.00/49.00, addr 2> on uhub2

But it not detected on the boot...
