1. The Hardware Is Not Faulty (Yet)

• Test on another PC: Plug it into a Linux laptop or a friend's Windows 11 PC. If it works there, your OS is the problem. If it fails everywhere, the device is dead.
• Check the cable: Many USB cameras and endoscopes use thin, breakable cables. A damaged data line will show the VID/PID (enumeration succeeds) but fail to stream video.

• Go to Huion official website → Support → Drivers → Search for your tablet model (by PID 7250: e.g., H640P, H420X, etc.).
• Download the full setup package. It will contain signed .inf, .sys, .cat.
