A high-end Thunderbolt 4 or USB4 docking station (e.g., CalDigit, Dell WD19) uses DisplayPort Alt Mode over USB-C, not USB 3 compression. These cost $200+, but they are plug-and-play.
Before troubleshooting drivers, it is vital to understand the hardware. A standard HDMI port on your laptop is connected directly to your GPU (Graphics Processing Unit). It uses native protocols. A USB 3 to HDMI adapter is different. It is essentially an external graphics card.
The adapter contains a small chipset (usually manufactured by DisplayLink, Silicon Motion, or Fresco Logic) that converts data from USB protocol to HDMI video protocol.
Why the driver is mandatory:
If you plug the adapter in and see a "Device descriptor request failed" or nothing happens at all, you are missing the driver.
If you want, tell me your OS and adapter brand/model and I’ll provide a step-by-step, specific driver download and install sequence.
