Windows 10: Rename or update outdated driver usb2ser.sys

Dear community,I can’t turn on core isolation due to outdated drivers, usb2ser.sys and ftdibus.sys.I followed the suggestions https://answers.microsoft.com/en-us/windows/forum/all/outdated-driver-usb2sersys/cd395ce7-ff6e-4bc0-a702-93ac048aff9c but it requires system permission including in safe mode.Is there another way to solve the problem? Or, how do I get systems permission?Kind regards

Thank you for posting your query on Microsoft Community.

I would suggest you download latest drivers from Manufacturer's Website.

Follow the steps to update the drivers:

• Press Windows key + X key and click on
  Device Manager.
• Expand respective driver. (The driver which was stated to be outdated.)
• Right-click on the driver and
  select Uninstall.
• Now, go to the Manufacturer's Website and download the latest driver.
• Once the download is complete, run the setup file and install the software.
• Follow on-screen instructions.
• Restart the computer and check

Hope this helps. Please respond if you have further related queries.

What is semav6msr64.sys & Mellanox Drivers?


I noticed semav6msr64.sys on my system earlier today (also via Autoruns), and eventually tracked down the program which installed it - you heard it here first! It's an Intel file, and just coincidence that SEMA Software authored a driver file with the same name.

On my system the driver was installed by the Intel Driver Update Utility Installer, which I'd installed to update my Intel drivers. Uninstalling this program after use doesn't uninstall semav6msr64.sys, presumably due either to a bug in the uninstaller or to laziness of the development team who wrote it. I don't like leaving software package remnants on my system for no good reason, so removed it as follows:

1. Create a System Restore Point in case the following steps cause any problems.
2. Uninstall Intel Driver Update Utility Installer, if it appears in the installed programs list in Control Panel.
3. Rename semav6msr64.sys to semav6msr64.sys.bk [to be deleted sometime later if no problems are encountered].
4. If, and only if, you're comfortable editing the registry, delete the following keys (otherwise just leave them, they'll have negligible effect):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_SEMAV6MSR64
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\semav6msr64

 

What is semav6msr64.sys & Mellanox Drivers?

Thanks - as I further check, I first disabled semav6msr64.sys using Autoruns then rebooted. I didn't have the first registry key but deleted the second and deleted the driver file. I now have no trace of semav6msr64.sys.
