Hi Peter and others,
The following .config options make it possible to use USB on a
Wandboard Duallite and likely other i.MX based boards. USB works for
me after loading the modules manually:
[root@wandboard ~]# modprobe ci13xxx_imx
[root@wandboard ~]# modprobe usbmisc_imx
[root@wandboard ~]# dmesg
...

A test-build that includes these options and that I used for
verification testing is temporarily available from koji:

I have made modifications to arm-boot-config that can boot this
kernel on an unmodified from upstream u-boot. A patch for a-b-c
should follow in a few days. Grubby needs to be able to set the
LOADADDR correctly, and I still have to look into that
(/etc/sysconfig/uboot can be used until grubby knows about
Wandboards).
ive started working on setting up wandboard u-boot to work in the way we
will want going forward. ultimately i want to use the sysboot command
in the pxe support to load a extlinux style config file on arm systems
