Unable to upgrade firmware on UR44

I have been trying to upgrade my UR44 firmware but am constantly getting the message “Error: UR is not detected.
Please check the connection and reboot this software”. The interface seems to be working as the output and input signals are getting routed fine ( I use Cubase, but used Garageband and CubaseAI to verify this). One strange thing is I am not able to access the console for UR44 using either the Steinberg USB control interface or through Cubase. Anyone knows whats going on?

same problem here.
You must deactivate the CC mode and restart the UR44
that works for me.


Waht is the CC mode?

It is a little switch on the backside turning the CC mode on and off.

CC mode is for using the Interface with an iPad

Thansk a lot … my UR44C has no such a switch :grinning:

we have the same issue with the UR 24c tried it with power supply through USB and through power adapter. same result both times. Any other ideas ?

Thanks for the responses. A quick historical update since that last post 4 years go. Turns out that the UR44 at the time could not be upgraded using my macbook. I invariably had to connect it to a windows machine (which i borrowed) and upgraded the firmware using that. A little strange that OSX wasnt on the list of OSs that supported this upgrade procedure. Havent faced an issue since then (happy owner of the UR44 for 4 straight years now) .
