Not running off of flash. The board is booting to an SD with this image:
ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7260-linux/binaries/ts-images/ts7260-linux2.6-etch.dd.bz2
The loadUSBModules.sh script isn't included in this image. The USB driver
modules are loaded in another script.
In any case, the USB drivers are loaded and they work fine. Again, I only have
issues with the file descriptors in /dev when hotplug is enabled.
