Libusbx issue under Windows with USB3 controller

[jmichelp]

By following the guide from the wiki on how to compile bladeRF lib and tools under Windows, we are told to use libusx-1.0.18.

At least under my setup (Win8.1 64bits Intel USB3 controller), I had corrupted samples: 1 sample out of 2 was zeroed. It took me some time to figure out that the libusb-1.0.dll is the root cause of that.

Moving to the latest libusb-1.0.19 ( http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.19/ ) and recompiling bladeRF lib + tools (just in case) solved that problem.

In addition, libusbx is deprecated since January (source: http://libusbx.org/ ) as it was merged back into libusb.

It might be worth updating the wiki and also issuing a warning in CMake if trying to build against libusbx

@jmichelp, thanks for tracking that down. I'll look to make the changes you recommend within the next couple days. Cheers!

I updated the wiki and adjusted the CMake LIBUSB_PATH default to libusb-1.0.19. In the future, I'll look to add some sort of warning, or just skip over libusbx entirely in the CMake module.

Closing this for now, as I think we've resolved the main issue of instructions and the defaults being out of date.
