KVM issues 3421W
I seem to be having issues with my KVM - laptop connected via USB - C to USB C on monitor. Using the Dell wireless keyboard dongle the keyboard works but mouse wont. Other periperals connected to monitor vis USB such as camera not working.
If I put dongle into laptop all works ok. if I plug camera into PC works.
If I plug USB C into a phone all peripherals work.
All dell software and drivers loaded.
On boot up keyboard and mouse work for moment but then mouse stops working.
How can I leave wireless dongle plugged into monitor so laptop can access USB accesories and Mouse?

Dell Support must verify the ownership and warranty status. Click the blue "Get Help Now" on the right to start a private live chat session. Share the private Monitor Service Tag with them.
Is this monitor still under warranty?
* Go here
* Enter your private Service Tag in the blank
* That will show you the specific model, warranty status, etc.
Do you mean the P3421W or U3421WE?
What Laptop model and operating system?
* Enter the Monitor Menu OSD
* Go to Others
* Choose Factory Reset
* When done exit the Menu OSD
Assuming the dongle is USB-A? Test it on all of the Monitor USB-A downstream ports.
