>Description:
The USB mouse is not usable neither in textconsole nor in X.

top shows higher activity of wsmoused and syslogd, when I move the mouse
(cpu load goes from below 0.01% up to over 10%, for both).
In the blue screen of mc, I can draw lines of black boxes (size 1 letter).
On the normal black text screen, there is no reaction on mouse movements.
X works, but the mouse curser does not react on mouse movement or mouse keys,
so X is not really useable. X wants to use /dev/mouse, but it does not exist.

In /var/log/messages I find some hundreds of the following lines:

	Feb 12 22:30:20 Brix wsmoused: ioctl(WSDISPLAYIO_PUTWSCHAR) failed
	Feb 12 22:30:20 Brix wsmoused: Invalid argument

After stopping with /etc/rc.d/wsmoused stop
and restarting with wsmoused -n nothing seems to happen.
But as soon as I move the mouse, the screen is filled with lines as below:

Brix# /etc/rc.d/wsmoused status
wsmoused is running as pid 380.
Brix# /etc/rc.d/wsmoused stop
Stopping wsmoused.
Brix# wsmoused -n
wsmoused: ioctl(WSDISPLAYIO_PUTWSCHAR) failed: Invalid argument
wsmoused: ioctl(WSDISPLAYIO_PUTWSCHAR) failed: Invalid argument
...
(more than 1 line per second)

With NetBSD 8, my USB-keyboard and my USB-mouse are recognised
during kernel initialisation, so I hope it will work in near future.
With NetBSD 7 they were not recognised,
even the USB installation stick was not recognised by the kernel.

Mouse recognition from dmesg:
---
uhid0 at uhidev1: input=2, output=0, feature=0
uhidev2 at uhub1 port 4 configuration 1 interface 0
uhidev2: SIGMACH1P (0x1c4f) U+P Mouse (0x03), rev 1.10/1.10, addr 3, iclass 3/1

>How-To-Repeat:
Start with wsmoused -n, move usb-mouse:
the screen is filled with lines as below:
wsmoused: ioctl(WSDISPLAYIO_PUTWSCHAR) failed: Invalid argument
