usb1 and usb0 sceduling overrun messages

[Larry Hammer]

Hello,
I am using FreeBSD 4.9 the documentation has given me most of my answers to 
configuration, but I cant figure this one out;
I am getting hundreds of theese mssgs in my /var/log/message files per boot
( very small clip from)
Feb  3 00:28:15 LH1 /kernel: usb1: scheduling overrun
Feb  3 00:28:15 LH1 /kernel: usb0: scheduling overrun
Feb  3 00:28:15 LH1 /kernel: usb1: scheduling overrun
Feb  3 00:29:03 LH1 /kernel: usb1: scheduling overrun
Feb  3 00:29:05 LH1 /kernel: usb1: scheduling overrun
Feb  3 00:29:05 LH1 /kernel: usb0: scheduling overrun
Feb  3 00:29:05 LH1 /kernel: usb1: scheduling overrun
Feb  3 00:29:05 LH1 /kernel: usb0: scheduling overrun
Feb  3 00:29:05 LH1 /kernel: usb1: scheduling overrun

I have recompiled the kernel to use only ohci and not use uhci 
since that is what my board uses it didn't fix the problem
IE;
# USB support
#device		uhci		# UHCI PCI->USB interface ** I did this LH
device		ohci		# OHCI PCI->USB interface
device		usb		# USB Bus (required)
device		ugen		# Generic
device		uhid		# "Human Interface Devices"
device		ukbd		# Keyboard
device		ulpt		# Printer
device		umass		# Disks/Mass storage - Requires scbus and da
device		ums		# Mouse
device		uscanner	# Scanners
device		urio		# Diamond Rio MP3 Player
# USB Ethernet, requires mii
#device		aue		# ADMtek USB ethernet
#device		cue		# CATC USB ethernet
#device		kue		# Kawasaki LSI USB ethernet

/etc/rc.conf
usbd_enable="YES"

/etc/defaults/rc.conf has a line I can transfer to /etc/rc.conf 
usbd_flags=""		# Flags to usbd (if enabled).

I am assuming that there is a way to flag this off 
I have no clue where to find information for theese flags, I looked thrue the 
man pages found just about everything but.

how do I fix this situation with the sceduling overrun errors on the usb ports 
I am using an ECS K7S5a mainboard with 128 ddr the usb ports are onboard

Thanks,
Larry
