[Discuss-gnuradio] USB 3.0 controllers for SDR

[Daniel Pocock]

The Ettus web site has a page about USB chipsets[1], suggesting some of
them can't handle the continuous streaming for SDR

Is this information up to date, can anybody else comment on this?

I'm looking at using a HP Z800 workstation which has quite a lot of
grunt but only has USB 2 built-in, HP supplies a PCIe x1 card[2], model
number QT587AA which is apparently able to use PCEe2 bandwidth and has a
Texas Instruments TUSB7340 chipset[3].  Should this be enough or should
I be looking for a PCIe x4 or faster solution?
