I would like to create a USB 2.0 hi-speed Target device.  I need to have 
all the control over the way the target talks to the USB Host (a linux 
computer).

in other words, I need a "quasi-development-kit" here.  the target needs to 
store a couple of gigabytes and be reasonably powerful.  beagleboards seem 
to be a possible ticket for the target.  good idea?  bad idea?

for example, I may want to create a device that is contacted by the USB 
host, receives a string, processes the string online, and then returns 
another string to the USB host.  (the USB host will run linux; the USB 
target will be a beagle, and it needs to run a C program that I have 
written.).  it is important that I have 100% control over the USB data 
protocol, so that the host cannot breach the target security.

of course, this is a development system.  I need to be able to wipe it and 
start over, upload the next version of my C program, and try again.

is the beagleboard a good ticket.  does anyone know of an example how to do 
this?
