USB detection gone on Etch system

[Carl Fink <carl@fink.to>]

I rebooted my Etch system yesterday.  Now it can't detect any USB devices. 
Support worked fine yesterday, but if I tail /var/log/messages, NO messages
appear when I plug in a USB device.

System freshly updated this morning.

Relevant-seeming packages are:

libusb-0.1-4			2:0.1.10a-21
libusb-dev			2:0.1.10a-21
usbutils			0.70-8
linux-image-2.6.12-1-k7		2.6.12-10
udev				0.070-2
hotplug				0.0.20040329-25

Anything I can do to help debug this, or is it just an "Etch is broken"
situation?

If you attempt to fix something that isn't broken, it will be.
