3. Check Updates via Thrustmaster Firmware Updater
Sometimes checking for the latest update via the Thrustmaster Firmware Updater tool on your PC can fix the issue because outdated software of the connected USB device may cause connectivity issues. To do so:
- Launch the Thrustmaster Firmware Updater tool on your PC.
- Go to the Start menu > Click on All Programs > Thrustmaster.
- Now, click on TH8A > Click on Firmware Updater.

- Click on OK to update the firmware.
- Once the update has been successful message appears, you can close it, and reboot the PC.

Please Note: If the shifter isn’t detected in the Firmware Updater window or if the update fails, try connecting the shifter to a different USB port on your PC, and then perform the steps again to see if that resolves the problem or not.
4. Reinstall the Latest Driver from Thrustmaster
It’s highly recommended to reinstall the latest Thrustmaster TH8A driver on the PC by following the steps below. Sometimes an outdated driver can also trouble you a lot.
- Install the latest drivers available from Thrustmaster’s technical support website for your TH8A shifter here.
- Once downloaded, make sure to run the installer application file on the PC, and complete the installation.
- Finally, reboot the PC to apply changes.
5. Update Windows Build
Well, an outdated Windows OS build can cause performance issues in most cases. Sometimes conflicts between the system and the USB device driver can cause connectivity issues whatsoever. You should always check for the software update on your PC and install the latest one.
- Press the Windows + I keys to open Windows Settings.
- Next, click on Update & Security > Select Check for updates under the Windows Update section.

- If there is a feature update available, select Download and install.
- It may take a while to complete the update.
- Once done, restart your computer to install the update.
If none of the methods worked for you, then make sure to manually perform a factory reset on your Thrustmaster TH8A gearbox shifter by following the steps below. Several users have found this method useful to resolve the shifter not working or can’t detect issues on the PC. To do so:
- There is a small hole on the TH8A shifter just beside the USB cable source. A small rectangular black button is there inside the hole.
- That’s a physical reset button of the Thrustmaster TH8A shifter.
- Simply use a paperclip or something like that to press and hold the reset button for a few seconds until you hear a clicking sound from it.
- Once you hear the clicking noise, make sure to unplug and plug back the USB cable to the PC directly (Don’t release the pressed button yet).
- As soon as the USB cable is connected to the PC, you can now release the pressed button.
It’s quite normal that sometimes your Windows PC won’t gonna detect the shifter in the Game Controllers Panel. So, nothing to worry about it. Keep trying the USB cable to connect to the PC several times.
If nothing seems working for you then you should contact Thrustmaster Support here to get further assistance. It’s better to start with a Live chat feature and then you can ask the support agent to create a support ticket for the same. If in case, there is an issue with the shifter physically then make sure to ask for a repair or replacement. They’ll guide you on it.
