Read and understand the information above. Scary? For many of us, of course! Impossible? Absolutely not! Lesson Progression You do that with a little program called Zadig. This driver is not included in the normal Windows driver package, so you have to go out, get it and install it on your machine. We would like to use a different driver when working with OpenTX Companion and the Taranis. In this day of Plug-n-Play, we’ve become used to simply connecting a new device, having the computer recognize it, install the appropriate driver, and we’re ready to go.

There’s only one goal in this lesson, and that’s to get your computer communicating reliably with your Taranis. Mac and Linux computers use a driver called: dfu-util-0.7.mpkg. Don’t worry! You’ll be shown where and how to download and install the driver and get your machine talking to your transmitter. Until that happens, the operating system doesn’t recognize the chip, and you’re dead in the water. The basic difficulty seems to be that Windows does not install the proper driver to allow OpenTX to communicate with the main STM chip in the radio. We’re going to get you through it, hopefully with as little anxiety as possible. It’s probably the single most feared, confusing, and frustrating thing about OpenTX, and has brought more than one enthusiastic OpenTX neophyte to their knees. If you’ve hung out in any of the forums at all, you’ve probably heard, and perhaps been alarmed by, the apparent difficulty that some users have when initially trying to update to OpenTX firmware for the first time.

USB3 is the newer version, and is usually indicated by having a blue insert/guide that is visible when looking at the port.

If you have the latest version of Zadig, try changing to a USB2 port, if available. You can download the latest version of Zadig from HERE. If you follow the steps in this lesson exactly and you still can't make things work, check to see if you have the latest version of Zadig installed. Several methods were tried to alleviate this problem, and finally Zadig was found to be the apparent solution. It seems to depend upon what chipset your machine uses. Introduction to Zadig NOTE: Some OpenTX users have reported difficulty using USB3 ports to communicate with OpenTX Companion.
