What are ssudbus.sys and ssudmdm.sys?
The ssudbus.sys and ssudmdm.sys drivers are related to Samsung smartphones or tablets. When you hook up a Samsung device to a Windows computer, these drivers are installed so the device can talk to the computer properly.
- This is the Samsung Composite Device Driver. It helps a Samsung mobile device work with Windows, making sure data moves back and forth without a hitch. Samsung Electronics Co. Ltd makes it, and it’s key for connecting Samsung devices.
- This one is for managing Samsung mobile devices, probably helping with modem or data communication.
When these drivers are old or don’t match up right, they can mess with turning on the Memory Integrity feature, leaving people scratching their heads.

The Memory Integrity’s incompatible drivers issue in Windows 11
Windows 11 has a cool security thing called Core Isolation’s Memory Integrity. It helps protect against tricky attacks that try to mess with your PC’s memory. But for it to work right, all drivers need to play nice together.
Trying to switch on Memory Integrity might show an error if Windows finds “ssudbus.sys” and “ssudmdm.sys” not fitting in. These drivers usually come from Samsung mobile devices you’ve connected before.
Uninstall ssudbus.sys and ssudmdm.sys driver
Before you do anything drastic, try uninstalling these drivers. Here’s how to do it step by step:
- Right-click on the “Start” button and pick “Device Manager”.
- In Device Manager, open the section for mobile devices or USB controllers (depends where the Samsung drivers are).
- Find any drivers linked to Samsung, right-click on them, and choose “Uninstall device”.
- Restart your PC.

- Open File Explorer (you can find it on the taskbar or press Windows key + E).
- Go to C:\Windows\System32 or C:\Windows\System32\drivers.
- Search for “ssudbus.sys”. Right-click on it and pick “Rename”. Change its name to ssudbus.sys.old.
- Do the same for “ssudmdm.sys”.
- Restart your PC.
Useful tip: Run CMD or PowerShell as SYSTEM in Windows 11
Ssudbus.sys driver download and update
If you still need these drivers for your Samsung device, get the latest ones which might work with Memory Integrity in Windows 11:
- Head over to the official Samsung website and look in the “Support” section.
- Find “Drivers and Downloads” and search for the newest driver for your Samsung device.

Verifying if Memory Integrity can be turned on
After fixing the driver issues, make sure the Memory Integrity feature is turned on. Here’s how:
- Open the Windows Security app.
- Click on Device security in the sidebar.
- Under Core isolation, click on Core isolation details.
Now, you should see if the Memory integrity option is there and turned on. If you can see it and it’s on, that means the ssudbus.sys and ssudmdm.sys drivers are not a problem anymore, and Memory Integrity is working fine. This means your computer has an extra layer of protection against bad malware.
If you can’t turn on Memory integrity or it doesn’t show up, it might be a good idea to check again if all Samsung software or drivers related to these drivers are completely removed from your computer.
Ending notes
Figuring out drivers and system features can be confusing sometimes. Even though Windows 11 brings a lot of good stuff in terms of user experience and security, issues like these show us how important it is to keep drivers up to date. Plus, it’s crucial for companies that make devices and the people who make operating systems to work well together to make sure everything runs smoothly for users.
