Zwift recognizing Computrainer again

[cycling_bears (Lisa T. [TeamLPC])]

I was having a lot of issues with my computrainer not being found on the pairing screen. After trying to use RacerMate to turn it on, it eventually stopped.

Thanks to co-pilot, I was able to figure out why Zwift could not locate any COM ports. It turns out that the pairing screen appears to be looking for Bluetooth devices ONLY and not COM ports.

To fix that you will have to edit your prefs.xml file found in My Documents.

Make sure Zwift window is closed.

Right click on the prefs.xml file and Open with Notepad.

Scroll down and add the following line after < ZWIFT >

<USE_SERIAL_PORTS>true</USE_SERIAL_PORTS>

So it will look like this:

What this does is that it tells Zwift to turn on old Windows serial-device pairing screen. It should be able to pick up the Computrainer and other wired trainers (if they exist).

Save. Then reload Zwift. Your computrainer should load very quickly in the pairing screen.

Please let me know if this worked for you! I hope this helps!

I tried your fix for the computrainer. It does pair right away but within a few seconds it drop off. I have checked the drivers and both the com port and the universal serial bus controller are still using 2.12.36.4 which was the problem a few months ago. Any ideas?

The additional thing I did was ask Zwift Support to fix the backend for me.

I am using the latest drivers.

Other advice:

1. Make sure nothing else is using the COM port. Close other programs or apps except for Zwift

2. Make sure you use ZwiftLauncher.exe (should have the Let’s Go button)

3. Download RacerMate from sram. Have it recognize the COM port (green and red light flashing)

I’ve tried: loading it before launching Zwift. And launching racermate after Zwift app is open. Sometimes I’ve had to continuously open and close racermate until Zwift recognized it

Hope that helps.
