'''Tundra Trackers''' automatically power on when connected to USB-C for charging. This behavior is intended and implemented at the request of enterprise customers. There is no firmware-level option to disable it.

The Tundra Tracker connects to SteamVR through a paired dongle (such as the Super Wireless Dongle SW3/SW5/SW7 or a Vive Tracker dongle). When a tracker powers on and finds its paired dongle, it sends a signal that SteamVR interprets as a request to start, the same way pressing a controller button does. This means plugging trackers in to charge can unexpectedly launch SteamVR.

== Option 1: Disable SteamVR auto-launch on button press ==

SteamVR can be configured to stop launching automatically when a tracker or controller sends a signal.

# Close SteamVR if it is running.
# Open the file <code>C:\Program Files (x86)\Steam\config\steamvr.vrsettings</code> in a text editor.
# Add the following key inside the top-level JSON object:<syntaxhighlight lang="json">
"power": {
"autoLaunchSteamVROnButtonPress": false
}
</syntaxhighlight>
# Save the file.

The file should look similar to this:

<syntaxhighlight lang="json">
{
"steamvr": {
...
},
"power": {
"autoLaunchSteamVROnButtonPress": false
}
}
</syntaxhighlight>

This also prevents launching SteamVR by pressing a button on VR controllers. SteamVR must be started manually from Steam or the desktop shortcut instead.

== Option 2: Unplug the dongle while charging ==

If the paired dongle is not connected to the PC, the trackers have no way to communicate with SteamVR, even if they power on during charging.

# After finishing a VR session, unplug the paired dongle from the PC.
# Plug the trackers into USB-C to charge as usual.
# Before the next VR session, plug the paired dongle back in.

This preserves the ability to launch SteamVR via a controller button press and requires no configuration changes.
