I've compiled in USB support into 3.1-R, just to see if I can perhaps see
a probe of my scanner (HP ScanJet 6200c).  During boot my dmesg looks like
so:

I have removed the scanner from the port and booted, and it still disables
the usb0 controller.  Is the VIA VP2 chipset not fully supported?
Motherboard is an FIC PA-2007 with the 82C586A chipset (as opposed to the
82C586B chipset).  My config file is as follows:

This works in Windows98, so I know the usb controller and the scanner work
together.  Should I wait for 3.2 to start playing with this?  

Also, do I need both the ohci and uhci controllers in the config file?  I
only appear to need the uhci controller, but it's not really documented
all that well.
