fast data pipe, 160 kSPS, for ADuCM350?

I am looking at the ADuCM350 for amperometric applications.  It looks promising, but I'm concerned that I won't be able to look at the raw data that is getting sampled at 160 kSPS.  The UART port is too slow, I believe.  How can I get the raw data piped out to a laptop so that I can graph it and watch the data as the experiment progresses?  (A delay is fine, doesn't have to necessarily be real-time ... but I do want to see all the data eventually).  What is the best approach for looking at this 160 kSPS raw data?  I noticed in the ADuCM350 Hardware Reference Manual, p. 183, that a USB stack for USB 2.0 (spec'd at 12 Mbps) is available from Micrium.  I called Micrium and they said that actually, with all the overhead of the USB, that they found that their USB stack (sending data out to their Windows app named "Probe") is actually slower than using J-link debug adapter to their Probe app.  I know that J-link is also not very fast.  So what is the best way to implement a fast data pipe?
