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?

I reported via the hub prior to the DEC updates.

Tested (as Matt Dooris) and issue still present.

Tested by delete old drivers and reinstall smartcard reader and last drivers (4.68) but same issue.

In my case, reader is "SCR35xx USB..." but issue is exactly the same and linked to the windows 24H2 upgrade

Exactly,

did the same today again, downloaded again the latest drivers from - https://support.identiv.com/scr3310v2/ 

and still didn't resolve the problem

to my luck that pc still had the 10 days grace period to restore to previous build so we did it and right away problem fixed.

i also contacted the manufacture - https://support.identiv.com/contact/

got a reply:

The latest Windows 11 update will cause the driver to be disabled.
Please turn of Memory Integrity in Windows 11 to resolve this issue.

Right click Windows icon.
Select System
Select Privacy and Security
Select Windows Security
Select Device security
Select Core isolation details
Turn off memory integrity

We tried it as well and it didn't solve the problem.

only thing to solve it was to restore back to previous windows build.

and sent them again a support ticked that it didn't solve it and a a link to this conversation thread - and asking them to contact Microsoft Team on behalf of their side, as it breaks usability with their product.

Already tested this and nothing change.

For me, issue is from "Smart Card Service" or discussion between this service and windows core, not on drivers side - all my test seems to confirm this, as if I delete drivers and unplug reader, issue is same on "certutil.exe -scinfo" command.

This solution worked for me, after spending the last three days scouring forums and trying numerous suggestions:

*I gave all available profiles full control. Not Sure if that is correct, but it worked.*

-Run Regedit.exe:

• Go to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\Calais

-Check the permissions for LOCAL SERVICE (if not there, add it). Make it "Full Control":

• Right-click on the key (Calais) and select "Permissions..." from the pop-up menu

• Click on LOCAL SERVICE to select it

• Allow "Full Control"

That's worked on my customers.

Don't miss to reboot computer to have change correctly updated.

This confirm that upgrade had an issue and windows do nothing about it....
