I seem to have missed David's response ...

Before you spend a lot of time on this, make sure the ARM9 you are 
looking at has an EHCI controller. I never did get the USRP to work with 
the USB1.1 controllers found on ARM( chips a few years ago. You need to 
mess with the Cypress/FPGA interface.

There may be some ARM( systems with EHCI controllers these days. I am 
not 100% certain though.
