ExtIO wrapper for librtlsdr.
Supports multiple dongles and on-the-fly change of gain, samplerate and buffer size.
Tested with HDSDR, fully supports new features (settings storage, HDSDR control of gain and samplerate)
Sources are in http://github.com/josemariaaraujo  
Latest version of librtlsdr and libusbx was used to make the dll.

Step-by-step installation (contributed by Leif from HDSDR)

* uninstall all software, delivered with the USB dongle (very important!!!)

* install HDSDR from http://www.hdsdr.de/download/HDSDR_install.exe

* download Zadig from http://sourceforge.net/projects/libwdi/files/zadig/
  Windows Vista/7/8: download the newest version - Windows XP users require a special zadig_xp version!

* extract Zadig using 7-Zip ( http://www.7-zip.org ) or Winrar

* install and start Zadig: press "Install Driver" to install the WinUSB drivers after selecting the right device(s).
Problems occur when the original driver (delivered with the USB dongle) is still installed!
These drivers sometimes do not get uninstalled correctly.
In this case, click Options and enable "List All Devices", then choose the RTL-device and press "Replace Driver".

* download ExtIO_RTL.DLL from https://github.com/josemariaaraujo/ExtIO_RTL/raw/master/Release/ExtIO_RTL.dll

* copy downloaded file into your HDSDR installation directory (default=C:\Program Files (x86)\HDSDR)

* (re)start HDSDR (select ExtIO_RTL.DLL if demanded)
