I have this mouse device:

ehci1: handing over low speed device on port 2 to ohci1
uhub3: port 2, device disappeared after reset
uhidev0 at uhub2 port 2 configuration 1 interface 0
uhidev0: Logitech USB Optical Mouse, rev 2.00/27.20, addr 2, iclass 3/1
ums0 at uhidev0: 8 buttons, W and Z axis
wsmouse1 at ums0 mux 0


It attaches and detaches properly after boot.

When I plug in the mouse before I turn on the machine, NetBSD
does not detect the mouse. I have to unplug and re-plug it.


>How-To-Repeat:


Plug in the mouse before turning on the machine.

dmesg | grep "ums"  is empty.

 I booted a kernel with EHCI_DEBUG and UHUB_DEBUG.
 ehci_debug and uhub_debug are set to debug level 1.

 Then in the dmesg at boot I get these message:

 ehci_disown: index=2 lowspeed=1
 ehci1: handing over low speed device on port 2 to ohci1
 ehci_pcd: change=0x04
 uhub3: port 2, device disappeared after reset
 uhub_explore: status change hub=1 port=2
 ehci after reset, status=0x00001005
 ehci port 3 reset, status = 0x00001005
 ehci after reset, status=0x00001005
 ehci port 2 reset, status = 0x00001005
 ehci after reset, status=0x00001005
 ehci port 2 reset, status = 0x00001005
 ehci after reset, status=0x00001005
 ehci port 3 reset, status = 0x00001005


 When I unplug and replug the USB mouse after boot
 then I get these messages:

 ehci_disown: index=2 lowspeed=1
 ehci1: handing over low speed device on port 2 to ohci1
 ehci_pcd: change=0x04
 uhub_explore: status change hub=1 port=2
 uhub3: port 2, device disappeared after reset
 uhub_explore: status change hub=1 port=2
 uhidev0 at uhub2 port 2 configuration 1 interface 0
 uhidev0: Logitech USB Optical Mouse, rev 2.00/27.20, addr 2, iclass 3/1
 ums0 at uhidev0: 8 buttons, W and Z dirs
 wsmouse1 at ums0 mux 0
