no ulpt0 in FreeBSD 5.1R

[bremner at unb.ca]

I am just setting up a new machine with 5.1R.  I have usb in the
kernel (I'm running the generic kernel from the install). 
My lexmark 323 which used to show up fine as ulpt0 under 4.9rc1 
does not show up anymore.

The machine is 845G based (it is an ibm netvista model 8037)

On the 5.1R machine I get 

dmesg shows three USB hubs
usb0: <Intel 82801DB (ICH4) USB controller USB-A> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
uhci1: <Intel 82801DB (ICH4) USB controller USB-B> port 0x1820-0x183f irq 10 at device 29.1 on pci0
usb1: <Intel 82801DB (ICH4) USB controller USB-B> on uhci1
usb1: USB revision 1.0
uhub1: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub1: 2 ports with 2 removable, self powered
uhci2: <Intel 82801DB (ICH4) USB controller USB-C> port 0x1840-0x185f irq 5 at device 29.2 on pci0
usb2: <Intel 82801DB (ICH4) USB controller USB-C> on uhci2
usb2: USB revision 1.0
uhub2: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub2: 2 ports with 2 removable, self powered

and my USB mouse works

ums0: Kensington USB Input Device, rev 1.10/1.11, addr 2, iclass 3/1
ums0: 5 buttons and Z dir.
ums0: at uhub2 port 2 (addr 2) disconnected
ums0: detached
ums0: Kensington USB Input Device, rev 1.10/1.11, addr 2, iclass 3/1
ums0: 5 buttons and Z dir.

But I get no report of ulpt0

on the 4.9pre machine I get
ulpt0: Lexmark International, Inc. Lexmark E323, rev 1.10/1.00, addr 2, iclass 7/1
ulpt0: at uhub0 port 2 (addr 2) disconnected
ulpt0: detached
ulpt0: Lexmark International, Inc. Lexmark E323, rev 1.10/1.00, addr 2, iclass 7/1

and printing works also.

Can anyone suggest some troubleshooting techniques? I'm new both to
USB and running FreeBSD 5.x
