Black Screened when Using USB4 Cable

#1 · 20/10/2025, 12:58

Hi,

My devices:

MSI Laptop (Windows 11)
Xiaomi Pad 6S Pro (HyperOS 2) (Supports USB3.1)
Both are installed with the latest spacedesk application.

When I was trying to connect my pad with USB4 cable, it went black-screened (as seen in the screenshot on Google Drive), and my laptop showed a prompt “1 connection pending…”

However, when I switched to USB2.0 cable, everything was fine.

I tried using the same USB4 cable with my USB2.0 mobile phone, everything was fine as well.

Maybe this problem is similar to https://www.spacedesk.net/support-forum/topic/does-it-not-support-usb-3-0/

Hi @qwer,

Thank you for the logs you sent. A few questions for our further investigation:
1. What model is the USB 4.0 you are using and is it a Thunderbolt cable?
2. Which port are you using in your PC to plug your USB 4.0 cable?

Hi,

Yes, it is a Thunderbolt cable 5 cable (type c to c).
I used Thunderbolt 5 port of my laptop.
