Windows Thunderbolt™ Driver Beta features
A: You’ll need a computer, equipped with a motherboard that supports Thunderbolt. If the motherboard doesn’t have a Thunderbolt™ port, you’ll also need a Thunderbolt™ AIC (Add-in Card). You’ll need a Thunderbolt™ 2 cable. If the port on your computer or AIC is Thunderbolt™ 3 (Type-C) you’ll also need a Thunderbolt™ 3 to Thunderbolt™ 2 adapter.
A: Every computer with a Thunderbolt™ 2 or Thunderbolt™ 3 support should work.
A: It depends. Thunderbolt™ requires explicit support from your motherboard. Check your motherboard specifications or contact the manufacturer to see if it supports a Thunderbolt™ AIC.
A: It depends. All Thunderbolt™ 3 ports are Type-C. However, not all USB Type-C ports support Thunderbolt. Type-C ports that do so will have the Thunderbolt™ logo besides them. It’s best to check your motherboard documentation to see if your port supports Thunderbolt.
Q: My motherboard doesn't have a Thunderbolt™ port, but supports Thunderbolt™ via an AIC (Add-in Card). What Thunderbolt™ AIC should I use?
A: It’s best to check with your motherboard manufacturer for a list of supported AICs. Typically, you can use an AIC from the same motherboard manufacturer.
A: Usually the default settings are OK and the device should be able to connect. There might be Thunderbolt™ settings that can prevent the device from connecting. The first one is “Thunderbolt Security” or ” Thunderbolt Authentication”. It should be set to “None” or “User” – depending on the motherboard. The other one is for Thunderbolt™ PCI support. This one should be enabled.
A: Any certified product should work.
Q: My computer should be supported and configured correctly, however, it still does not detect the device. What should I do?
A: Try updating your BIOS to its latest version. Also, you might want to update the Thunderbolt™ firmware to the latest version. Check your motherboard and Thunderbolt™ AIC (Add-in Card) manufacturer instructions on how to do this.
Workaround: Disable “Power Throttling” from registry and restart:
Run “regedit”. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power. Create a new Key “PowerThrottling” if not present, and a new DWORD value “PowerThrottlingOff” under the key, then set the value to “1”. Restart the computer.

Workaround: Select and configure your Power Plan before starting a playback / recording session.
On some machines, when the device is connected before the computer is started, Thunderbolt™ stack is not loaded and device is not enumerated.
Workaround: Connect the device after the computer is powered on.
Workaround: Disconnect the device before upgrading the driver.
Some DAWs register themselves to the Multimedia Class Scheduler service (MMCSS), which can throttle the audio processing threads to allow for lower-priority and background tasks to run. This causes background tasks to preempt the DAW and the ASIO driver, which causes spikes and dropouts.
We’re working with Steinberg to fix the issue.
- Disable Multimedia Class Scheduler service from the registry:
Run “regedit”. Go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MMCSS. Change the value of “Start” to 4. Restart the computer. This will permanently disable the service.
- Set the DAW process priority to real-time. Either start the DAW as Administrator, or set it manually from Task Manager: After you’ve started it, open Task Manager, click on “More Details”, find the DAW, right-click and select “Go to details”, right-click on the process executable and select “Set Priority -> Realtime”. Confirm the prompt by clicking “Change priority”.
