USB Mouse vs. Sound problem

Hi all,

I've recently installed FreeBSD 4.9 on a laptop and I've got into this

When I attach the USB Mouse on boot I get a fully working mouse, if I
start X (KDE) I didn't hear any sound unless I move the mouse around
during KDE's startup, if I stop moving it the sound also stops, the same
thing happens on XMMS while I play a CD. Then, if I unplug the mouse I get
full sound experience on my desktop, but I cannot replug the mouse and get
it to be re-initialized.

If I boot without the USB mouse, I don't get any sound from KDE or XMMS,
even if I move the touchpad.

Here is some output from my laptop:

# dmesg | grep pcm
pcm0: <Intel ICH3 (82801CA)> port 0x1840-0x187f,0x1c00-0x1cff irq 9 at
device 31.5 on pci0
pcm0: <Yamaha YMF753 AC97 Codec>

# cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Intel ICH3 (82801CA)> at io 0x1c00, 0x1840 irq 9 bufsz 16384
(1p/1r/4v channels duplex)

I'have configured artsd to use /dev/dsp0.1 so XMMS can use the default
/dev/dsp0.0 and the problem is still the same.

Also the output for the USB mouse:

#dmesg | grep usb
usb0: OHCI version 1.0, legacy support
usb0: <NEC uPD 9210 USB controller> on ohci0
usb0: USB revision 1.0
usb1: OHCI version 1.0, legacy support
usb1: <NEC uPD 9210 USB controller> on ohci1
usb1: USB revision 1.0

# dmesg | grep ums
ums0: Logitech USB-PS/2 Optical Mouse, rev 2.00/11.10, addr 2, iclass 3/1
ums0: 3 buttons and Z dir.

I'll appreciate any help. Thanks in advance.
