How to take samples of data from USB of TMS320C6713?

Mike and Ujala,

a USB daughtercard won't do the job - these are all USB peripherals
(device or function in USB terminology). You need a USB host to take the
role of the PC. One solution is using the OMAP-L137/TMS320C6747 EVM
board which includes a USB host controller, and is code-compatible with
the 6713. AFAIK, the software support for the USB host is not yet
completed, a bit of pioneer spirit will help...

i have a similar application, what i have done is that i used the dsk HPI
daughtercard from educational DSP and used MATLAB to down/Up load data from
the the tms320c6713 dsk card (i assume that you are using a similar
educational development card)... but for this you have to write your own
interface
