Crash on start: The driver type 'USBPRINT' is not supported yet

I'm getting the following error since upgrading to the latest version:

Oh wow, looks like the usbmonitor package doesn't like a specific usb-connected-device ?

Looks like this is a known issue

So for now it looks like the combination connected usb-printer + windows will lead to this issue :roll_eyes: The "workaround" is to disconnect the printer, but obviously this is not really a nice solution - we'll try to get in contact with the usbmonitor maintainer to see how we can solve this.

How did you install nitrokey-app2 ? Do you by any chance know how to modify the usbmonitor sources so we could extract some more details what happens?

Yes, I have two Dymo label printers connected via USB. I can start Nitrokey App if they are disconnected upon start of the app. Installation was through downloaded MSI file.

Happy to send you more data. Just let me know what to do.

Hi, I have exactly the same problem on Windows with versions 2.3.3 no matter if installer or portable. A Dymo label printer is also connected here. Deactivating in the device manager is not enough, the device must be completely disconnected.

Is there anything new on this yet?

Looks like this issue has been fixed upstream in usb-monitor v1.23. I’ve created a PR to update the dependency: https://github.com/Nitrokey/nitrokey-app2/pull/318.

Fixed in version 2.3.5.
