Steinberg UR12 electronics schematic

Hi

I have the same problem as from topics listed below

UR12 worked perfectly until I unplugged it.

I am so frustrated. I’m trying to set up a (Windows 10) laptop so I can work on Cubase away from home. So I picked up an inexpensive UR12 and yesterday, successfully installed it on the lap top and got it working in Cubase with no problems at all. And the installation was fast - I just downloaded the driver from Steinberg, installed it, plugged the device into the USB 3.0 port on the lap top and that was it. It worked immediately. I didn’t have to sign on with admin privileges, didn’t have to …

Computer does not recognize UR12

On yesterday and the days before that, my UR12 was working perfectly. However, on this morning, my computer did not recognise my UR12, the USB signal light on the machine was continually blinking, I couldn’t find the device in Control Panel. I also tried to uninstall and re-install the software and to upgrade them through the download on steinberg.net, but the problem is still the same. I tried on other computers and received same results, what else could be wrong?

In fact these topics have no (useful) answers, moreover technical support no answering me so I repeating the problem.

After unplugging USB, my UR12 device doesn’t recognize at all. Changing computer, cable, USB port, drivers didn’t help at all. It just blinking. And give no connection to host

So I gone further and disassembled the device to the electric circuit. I tested the USB 2.0 connection and it works. 4 pins of USB 2.0 gives satisfied values (5.0V, -0.01V, -0.01V, 0.V)

To understand and debug where problem further I need an electric scheme. While measuring Voltage in some critical points it is possible to debug and fix the issue. But I need principal scheme to know what to debug

So, that’s query for you, Steinberg Devs. If you don’t care about technical support ( and you don’t since you still keep silence on coming techinical questions and problems) - just share electric scheme and I will do your job by myself.

Of course, if you not from Steinberg but know how to solve problem - you are very welcome.

And thank you anyway
