Hello and welcome to Apple Support Communities, erzhuo.

If we understand your post correctly, not all of your accessories are working with your MacBook Pro. We’d like to help.

Hello erzhuo.


Let's do some testing to narrow down the issue. Safe mode will tell us if the issue is related to a startup item or plugins, and sometimes corrects the issue. This article will tell you how: How to use safe mode on your Mac

Thank you for your reply. 

I tried the steps you mentioned however still it didn’t work.

Whenever I connect the accessories, the led blinks/on indicating there is power. And when I write with the digital pen, it is blinking indicating the activity/input but I cannot see anything on the screen.

I tried reinstalling the driver, I reset the SMC and NVRAM but still, nothing happens. 

Thank you

I am using veikk s640 for the digital pen. I tried using my printer but it is no longer working as well. The only device that works until now when connected to the ADAM element USB-c 5 ports is my external Hard Drive. So disappointed, I can't use it when I teach and having difficulty solving problems without the pen.

I tried connecting these devices to another laptop and it is working.


Thank you
