eLicenser Error for a Cubase Version That is Not Even Installed

All of the sudden I am getting the following error on startup of Cubase PRO 11.0.41:

eLicenser Control - Error
Application ‘Cubase Artist 11’ has caused the following error:
There is an USB communication problem. Please connect the eLicenser to another USB port.

Well… I don’t even have Cubase Artist 11 installed. I’m a Pro 11 user. Any ideas?


Cubase Pro 8.5, 11, 12, 13 - RME Fireface UFX II - Windows 10 Home - Intel i7-8700K | 3.7 GHz | 32 GB RAM - NVIDIA GeForce RTX 2080 - All drivers up-to-date


What does it look like if you start eLCC application? Can you see the Cubase Pro 11 license? Could you try another USB port, please?

Cubase Pro and Cubase Artist are the same executable; the enabled feature set depends on your licence.

You will need to debug the eLicenser problem - I suggest you follow @Martin.Jirsak 's steps.

Hey all, thanks for your replies and apologies for the delayed response.

eLCC app shows I have the Cubase Pro 11 license as expected.

If I pull the eLicenser USB dongle out and put it back in (same port or different, it doesn’t matter), then the error goes away, and Cubase Pro 11 starts as normal. This happens about 30% of the time after I boot up my machine and start Cubase. When it does, I have to pull out the dongle, put it back in, and then I can go.

But this is kind of tedious. I shouldn’t have to pull my dongle out and put it back in every time I want to run Cubase…

Could this be a USB hub issue, wherein I have too many devices fighting for priority over the bus?

Thanks all!


Yes, it could. Is it a powered USB hub?

Hi Martin, yes, it is. My PC’s USB options are limited and so I opted for a powered USB hub to provide more connections and it has worked just fine this way for a couple years now. I have not changed anything physically, so I am not sure why all of the sudden I am having this issue.


The USB-eLicenser might be broken.
