4.99.20
>Description:
During bootup, after usual boot messages, like:

uhidev0: Logitech USB-PS/2 Mouse M-BA47, rev. 1.00/1.20, addr 2, iclass 3/1
ums0 at uhidev0: 4 buttons and Z dir
wsmouse at ums0 mux0

...then all is frozen, no more booting. The above are "last words" from the system.

The system seems not to be hung, because i can call the debugger via
<Control>-<Alt>-<Esc>

----------------------------------------------

- no such problem were under NetBSD 2.0 neither 3.1
- when the mouse is disconnected before boot-up, the system is started quite normally, and then one can connect the mouse, which seems to be properly recognized by the system then.
>How-To-Repeat:
Just by using "jihbed" live-CD with this particular mouse.
