Hey Mike, did you also connect monitor’s power supply to the wall outlet? The Onefinity Controller is not able to supply enough power to drive the monitor. > [@How to connect the Touch Display (7, 8, 10.8")](https://forum.onefinitycnc.com/t/how-to-connect-the-touch-display-7-8-10-8/5081/1): > > When connecting a touchscreen to the Onefinity controller there are a few key items to make it work correctly: Step 1: POWER: Every screen must be connected to external (wall) power to operate correctly. Skipping this step is the most common mistake users make. On the 7 and 8" screens, the 12v wall power adapter must be connected to the 12v in (red arrow) port. On the 10", there is no 12v power input, instead, a USB C port labeled with a lightning bolt is used (red arrow). This cable must be … ---

Yes it is connected to power. The screen shows the Onefinity booting up and goes to the screen where it asks if you want to home it. The pointer and the touch screen just don’t do anything. ---

Hey Mike, then it is likely that the USB device is not found by the system. Are you sure that you connected the USB cable to the right USB port on the Monitor? ---

The only port on the monitor that goes to a usb is a usb type b to a regular usb that I plugged into the controller. The forum says this monitor is compatible. ---

Hey Mike, according to [Confirmed Aftermarket Screens/Monitors that work with the Onefinity](https://forum.onefinitycnc.com/t/confirmed-aftermarket-screens-monitors-that-work-with-the-onefinity/4484), Asus VT229H works. You could open a terminal window with Ctrl-T Ctrl-C and type: `sudo grep -i touch /var/log/Xorg.0.log ` If a touch device was found, it would be shown. Otherwise this command would output nothing. Next, what happens if you type: `sudo tail -F /var/log/syslog` and then you plug the USB cable in? ---

Thank you for your help. You steered me in the right direction. The cable that came with the monitor was bad. Found a nice longer cable and it works just fine. ---

This article was helpful. I suffered the same and replaced ASUS Type-B USB cable with a longer spare out of my junk cable box. Voila’ I have a working Onefinity and touchscreen monitor!. I wonder how many bad cables ASUS has shipped with their monitors….?
