Install PC Driver Software (libusb)
To operate any of the Ensemble rigs, you will need to have the latest "libusb" driver installed successfully on your PC. This driver software makes it possible for the PC to communicate with the AVR ATTINY85-20 microcontroller on which the firmware for controlling the Ensemble resides. The firmware (as of 6/01/2011, V15.14) has been programmed into the AVR AVR ATTINY85-20 microcontroller that you received in your kit.
Installation of the USB driver (as of 9/20/2010, the version is V 184.108.40.206) involves installing a special "Certificate Authority" (making the driver a "signed" driver) and installing the actual driver, which is signed using that authority. The instructions and download links for this step are shown in the table below.

When you are done, you want to see something like the following (this was from the "Device Manager" listing on a Win 7 64 bit machine, installing the certificate and the signed driver):
If you have issues, they are likely to manifest themselves by the windows device manager showing an "Unknown Device". This can be due to one of the following causes:
Hardware:The rig end of the cable has issues with the AVR ATTINY 85-20 microcontroller being able to "tell" the PC it is there (bad chip; inadequate power; incorrect resistors; failed diodes; etc.)
USB Conflicts.The rig's USB id is conflicting with some other USB connected to the PC. Some have reported this occurs with wireless mouse/keyboards, especially from Logitech. To check for this, one should "uninstall" the "Unknown Device" in device manager, unplug all other USB cables, plug in the Ensemble's USB plug and see if it is recognized and then installed.
USB HubThe problem can occur when plugging the Ensemble into an external USB Hub. You should always try to avoid using an external hub; use a USB connector on the PC itself
Install the Configurator Program (CFGSR)
In this step you will install the special program that allows you to configure the AVR ATTINY85-20 microcontroller in the Ensemble. You will need to download and install the program itself, along with a dynamic link library (dll) which helps the program talk to the AVR through the libusb driver. The table below provides the links to the software and the installation guides.

Install SDR Software
Now, download and install the SDR Software. Most builders will want to use tried and true software (Rocky or Winrad) for their intial operation and testing. There are fewer "bells and whistles" with these two programs. It is best to get the RX or RXTX working with these to make sure you have properly functioning hardware. Later you can go after the "sexier" PowerSDR variants.
The table below provides the info and links for the two most popular programs.

|ExtIO_Si570 DLL||see note below||see note below||N||Y||Allows HDSDR or WinradHD to interact with Si570|
Note re ExtIO_Si570 dll: Per Bob, G8VOI, a much better option now, and really the recommended path is to install CFGSR v2.3 using the download from Fred's website. Once installed go to the CFGSR folder in Program Files and copy the version of ExtIO_Si570.dll from that to put in the Winrad folder. This then gives all of the same options available when running CFGSR from the 'H' key within Winrad.
