settings usb mouse rate

[Alexander Best]

i tested the patch with rates of 1, 100 and 1000:

1: random copy&pastes when moving the mouse
100: also random copy&pastes when moving the mouse
1000: OK

setting hw.usb.ums.debug=15 indicates that the polling rate is set exactly to
moused's -F value.

at some point i experienced a crash including a reboot. no core dump was
produced however. i've tried to reproduce the crash but wasn't able to. i
think the crash occured when i booted with a low -F value, then set -F to a
higher value in /etc/rc.conf and after that unplugged the mouse and plugged it
in again. as i said i'm not able to produce the panic any longer. might have
been caused by old code fragments in my /usr/src.
