Just wanted to let all the people who are having USB 3.0 problems know
that I am running a
Hootoo HT-PC001 SuperSpeed USB 3.0 4 port PCI-E card which has the
RECOMMENDED
VIA VL805 (VL80X to quote the Ettus web page) chipset. I did my research
and purchased it at
the end of 11/2013 for $19.99 from (can I say) Newegg. It is running on
an Asus P6T Deluxe V2
w/  i7-920 with an Intel X58 chipset thats been running since 9/2009. It
works in Windows 7 as
well as Ubuntu Linux. So here is a card you can use instead of a USB2.0
port or a non-supported
USB3.0 port. Yes I do get some overruns, but that could be a lot of
things. Ill figure it out.

And to the insulting gentleman that keeps harping on the "Ettus boards
only working on USB 2.0,
there are many more that have gotten them to work with USB 3.0, they
just dont complain about
things that work. We all know that the people out there who are not
helping others are just there
to vent, complain and bad mouth things they did not bother to learn
about. My recommendation to
them is to stick with MS Windows, buy a $20 SDR dongle, use the software
that does not need to
be compiled. And then when they have a clue as to what they are doing,
move up to a board that
does what they need or want it to do. The B200 did what I wanted it to
do, so I bought it over the
others.
As with any group of people, you will have the appliance operators that
can not do much more than
Plug n Pray.  And you have people that are more technically inclined.
They can assemble their own
systems and run an operating system that they can modify and compile
themselves. Now take a
look at the reviews on the HooToo card, you have folks that swear by it
and love it. They most likely
know what they are doing. And you have those that fried their
motherboards. I try to imagine what
they could have done to have such spectacular failures. They probably 1)
did not read the installation
manual and/or 2) did not connect the power to the card as specified and
it drew too much power thru
the PCI slot. Can you say "Bzzzzzzt, Pfffffffft, Pow".
And you sound just like the guy that is so legend, wait for it, dary on
so many of the SDR forums.
The one who never gives any real facts, whos post usually break down to
a swearing match.
Keeps saying that its coming real soon and that it will be made in
Chicago by WindyCitySDR.
So just tap your ruby slippers together 3 times while saying Its coming
real soon, Its coming
real soon, Its coming reeeeeeeeal soooooooooon.
And the hardware you are hocking (-quotes from your/their web site):
-Wide RF range 33Mhz-4400Mhz *(1). What does the *(1) define, I searched
your web site
and found no info on what that defines or what that discredits. Or does
it look more professional
that way?
-64MSPS 14bit AD. Thats A/D, get it right. Or did you mean Anno Domini?
-128MSPS 12bit DA. yep, that should be D/A or Digital to Analog in case
you did not know.
-USB2.0 H/S connectivity provide(S) (a) max 8M(bits? or bytes?) sampling
bandwidth(16bit).
To quote the Crowded House song, "Try to catch the deluge in a paper
cup.  You want to cram a
lot of data thru a little straw.
-DC Characters. Which one, Superman, Batman, Wonder Woman, Aquaman?
Their are just
too many to list. Who did your web page? Is English their first or
second language? And all your
numbers tell me that you subscribe to the This one goes to 11 mentality.

Please excuse any spelling or grammatical mistakes. I am going to bed
now.
Thank you all on the Discuss-gnuradio Digest for such useful
information.

P.S, I do not work for Ettus Research. But I do hold them with high
regard for all they
contribute to the SDR community. And I dont play one on TV either!

And by the way, its Nuts not Nutts. You couldnt even get that straight.

The Syba SD-PEX20122 works well too.  No issues streaming 46 Msps into
GR QT
spectrum or uhd_benchmark.  I get over-runs past that, but I'm not sure
if
that's the B200, USB card, or CPU trying to keep up.  Stay away from the
Renesas controller though, that's what on my motherboard and it's a hunk
of
junk.

I've actually had decent luck with a couple of renesas, but many people
do
report problems.  I just tried the Sabrent CP-4TU, though, with a VL800
chip, and it wouldn't even see my B200.  But, others have had success
with
the VL800, so it's down to the actual implementation of it.  I'm waiting
on
a VL805-based board which should be here this week.

Overall, I'm A) not surprised by the overruns I'm getting, or the
problems
that people are having, and B) still happy/impressed with the
performance of
my B200.  Still sorting out getting different software to work (GNURadio
is
next on the list!), but enjoying it nonetheless.
