About this tag
The usb upstream tag on WindowsForum.com covers the often-missed cable connection that links a monitor's built-in USB hub to the PC. A single tagged thread explains why the USB ports on a monitor can appear dead even when video works perfectly over HDMI or DisplayPort: the display cable and the hub's upstream link are separate connections. The discussion points to Dell support guidance and an Engadget guide that identify this as a common cause of support tickets where keyboards, webcams, flash drives, or wireless receivers stay invisible to Windows. It is a practical troubleshooting reference for anyone diagnosing monitor USB ports.
