How to get GUID and device ID for PDF24 with a USB blocking policy?

[yingwu01]

We have a conditional access policy to block the USB drives on users' PC. During our tests, if I turn this policy on, the users can't use PDF 24. If I turn the policy off, then users are able to use it. I need to get the DeviceID and the GUid for each user and add them into the exception list, but I have a user having the event information section empty, and it doesn't show the DeviceID and guid for her PDF 24. How can I find the the DeviceID and the GUid for the user?
Any suggestions are very appreciated.
Thanks very much!

Hello,

PDF24 is not a USB device and has no device ID or GUID of its own. If the policy also controls printers, the PDF printer of PDF24 is the part it may block:

• Classic PDF printer: printer name "PDF24", driver "PDF24", port \\.\pipe\PDFPrint
• Driverless PDF printer (since version 11.31.0, Windows 11 24H2 and later): Microsoft Virtual Print Class Driver, app package PDF24.Wpp_3w7hzerhx5424

Details: https://creator.pdf24.org/manual/11/#63-classic-and-driverless-pdf-printers

If the problem still exists with the current version, please tell us which product applies the policy, what exactly fails in PDF24 (printing to the PDF printer, starting PDF24, saving files ...) and which message or event you see. You can send us a screenshot with this button:
