Marcus - I understand you are trying to help but you keep asking everyone
this same questions - have you considered that people might not know? They
are not experts and download what is on the Ettus site. Would it not be more
helpful to point everyone to a version that does actually work?

In the meantime, I am also rather fed up and wondering if anyone is
interested in a second hand B200 because after 5 months it's still a useless
peripheral under windows and I don't see that changing any time soon.

Mike

The B200 isn't, yet, officially supported under Windows, to be honest.

But it should work.  What UHD version are you using?

The thing is, the B200 does work under Windows, but it hasn't been
thoroughly tested.  The reason I ask about UHD version numbers
is that, well, if you're running a version of UHD that was released
prior to the release of the B200, it can't possibly have support
in it for B200. That's why I ask people what version of UHD they're
running.

Granted, if the end-user is running some "turn-key" application, they
may not know what version of UHD they're using, particularly if the
"turn-key" application doesn't expose the UHD library startup output
when their application starts up.  So, in those cases, simply
run:

<install-path>\bin\uhd_usrp_probe.exe --args "type=b200"

In a command window to find out, it will produce a log like this (this
is from a Linux install, but similar output).  Note that it shows the UHD
version number.

linux; GNU C++ version 4.5.1 20100924 (Red Hat 4.5.1-4); Boost_104400;
UHD_003.006.002-1-g9fd308b3

But I can't diagnose remotely without knowing a few things, like the UHD
library version number.  If people are running UHD prior to
3.5.4, there'll be no B200 support at all, and with 3.5.4, it's
very preliminary, and almost certainly doesn't work on Windows.
I ask questions not to be annoying, but, rather, to try to get data
to help me diagnose and hopefully solve, issues.

The 3.6.2-rc2 release should work better on Windows, but again, Ettus
hasn't done extensive testing yet on Windows for the B200.
It's coming, and the only thing Ettus tests on is XP, Vista, and Win7
at the moment.
