[meta-ti] No USB devices on BeagleBoard?

I've built a minimal Linux for my BeagleBoard xM (Rev C) using the Yocto
project build appliance, and installed it on a uSD card. I used the
"Beagleboard" machine and "core-image-base".
It works (Yay!), has a small footprint and boots really fast which is
what I want. I used a pretty minimal build recipe with this in mind.
It gives lots of encouraging messages about loading drivers for the USB
devices. However, when I log in, there is no ethernet interface, and
nothing else on the USB seems to work. I've tried plugging in a USB
memory stick but it's not recognized (nothing new appears in log shown
by "dmesg"). I don't get anything on the display, either - I am
interacting over the serial port console.
I'm using the u-boot binary built by Yocto, and loading the device table
(dtb file) and kernel image from the same source. However, I noticed
that the (working) Debian image I have also includes an "initrd" image.
Borrowing from the Debian boot environment, I was able to load that
initrd (actually "uInitrd", the uboot image version?) but I still don't
see the USB devices.
Am I missing something? Do I need to put something in my Yocto build, or
should it already know about the hardware? Given that I picked the
"beagleboard" option, I assumed it knew what to put in. Do I even need
an "initrd"? According to the docs I read, this is a ramdisk which tells
the kernel which driver modules to load, but I don't really understand it.
Here is the (Entire!!) boot up output copied from the serial console. I
ran the uBoot commands manually to boot the kernel. For the project, I
just need the onboard ethernet to work, and support for a couple of
additional USB-Ethernet adaptors. Everything is working well in the
BeagleBoard Debian distribution I have, but I am trying to make my own
(preferably lighter and faster to boot).
Thanks for any suggestions!
