E-MU 0404 USB driver

I have reset the laptop. I guess the problem is because of USB 3.2 Gen 2 and nothing can be done. The device and driver is not maintained by the manufacturer.

Hi GeyzeR,

Thank you for reaching Microsoft Community. I'm sorry to hear about the driver issues you encountered when using the E-MU 0404 on your Surface Laptop 4.

I'm not sure what could be the exact cause of the issue. It could be due to an outdated/corrupted driver or could be incompatibility with the port since both Surface Pro 4 and Surface Laptop 3 has a USB 3.0 port while the Surface Laptop 4 has USB 3.2 Gen 2.

Anyways, kindly try first running these steps then see if the issue persist:

1: Run Surface Diagnostic Toolkit

See: Fix common Surface problems using the Surface Diagnostic Toolkit (microsoft.com)

2: Check for Windows Update

Go to Windows Settings > Update & Security and select Check for updates

Make sure all updates need are installed including Optional updates

3: Update drivers and firmware

Check what is the current OS Build of your Windows version by going to Settings > System > About. 

Go to Download driver and firmware for Surface, choose Surface Laptop

Then click the link next to Surface Laptop 4 then click Download on the next page.

Choose the .msi file that matches your current OS Build and click Next.

After downloading, run and install the .msi then Restart. 

4: Run System File Checker Tool

See: Using System File Checker in Windows (microsoft.com)

If still the issue persist, proceed with the steps below:

1: Update driver manually in Device Manager

Open Device Manager

Look for the E-MU 0404 USB driver

Right-click then select Update device

Select Search automatically for updated driver software

2: Uninstall/Reinstall driver

Open Device Manager

Look for the E-MU 0404 USB driver

Right-click then select Uninstall device

Note: If prompted with a checkbox stating "Delete the driver software for this device", check the box then hit Uninstall.

After uninstalling, unplug the E-MU 0404 USB then restart your Surface

Hope this helps.

Kind regards,

Marrion
