We upgraded to 24H2 and now our SCR3310 card reader is no longer recognized and we now cannot log in with our CAC card. Is there a fix?

We downloaded latest drivers, removed and reinstalled the driver, tried different USB ports. It shows up as working properly in Device Mgr but that's it. The light won't come on, it ignores the reader. Help.

    Thanks, Phillip. This was kicking my rear for a while. This solution worked.

    We are having the same problem with our SCR3310v2 readers after the update to Win11 24H2, we installed the latest drivers from SMC, then applied the registry fix from JHTN and this fixed our issues.

    Thanks JHTN!!!!

    Just doing step 4 (Download the most recent driver version from SCR3310v2.0 USB Smart Card Reader Drivers, Downloads, Support | Identiv (should be version 9)) fixed it on my computer w/o any additional intervention. The version is 9.02 w/ a date of June '24.

    Hope this helps!

    My new Lenovo IdeaPad with Snapdragon XPlus (ARM) still won't recognize my smartcard even after following these instructions. Keeps saying can't find certificate, even though I went through and got the new cert from my IT dept. Looking in device manager, it says "Unknown smartcard".

    I had ran into same issue with multiple users and have the fix for the issue

    Step 1. uninstall the device in device manager while selecting to remove the driver
    Do this until it shows the Microsoft driver shows (Microsoft Usbccid Smartcard Reader.
    --- I had to remove the device twice as there are two separate drivers.

    Once you have the Microsoft driver you have to set permissions on a registry entry.

    HKLM:\SOFTWARE\Microsoft\Cryptography\Calais

    You have to give "Local Service" full control over that Calais key
    Reboot the PC and you should be good to go. I have fixed 10+ machines this way so far.

    Here is a script (I didnt not write it) that does the registry fix for you

    Start Powershell ISE as admin and run the following

    $acl = Get-Acl HKLM:\SOFTWARE\Microsoft\Cryptography\Calais
    $rule = New-Object System.Security.AccessControl.RegistryAccessRule ("local service","FullControl",@("ObjectInherit","ContainerInherit"),"None","Allow")
    $acl.SetAccessRule($rule)
    $acl |Set-Acl -Path HKLM:\SOFTWARE\Microsoft\Cryptography\Calais
