I use Cubase 6 on a laptop and I use a Roland UA-25EX audio interface as the soundcard. I have been using both together for some time now without any problems, but all of a sudden, when I try to switch to the UA-25EX in the device manager, the message “Can not find a device. Please connect the device” appears. The UA-25EX is plugged in, but I’ve tried unplugging it and plugging it in again. I’ve tried uninstalling and reinstalling the drivers for the audio interface, but this has not helped. Occassionally, Cubase does allow me to switch to the UA-25EX, but Cubase performs poorly and soon crashes. The audio interface works fine just playing sound from my computer, such as an MP3 or when using the internet, so I guess the problem isn’t with the UA-25EX, but with the Cubase settings. I don’t know what else to do. Any help would be much appreciated.
