Right-click and select "Uninstall device,"
Consequently, you might see this device labeled under various brand names, including "Super Top", "Generic", or even other consumer brands that have rebranded the base hardware. However, the fundamental chip design remains the same.
This solves the infamous Code 39/Code 41 errors. Warning: Editing the registry is safe if you follow steps exactly. Back up first. USB Flash Drive Speed Tests - VID =
Devices utilizing the 14CD:1212 profile are built around mature, low-cost engineering standards: microSD card reader (SY-T18) — USB 14CD:1212 - DeviceHunt
If you see VID_14CD PID_1212 , you almost certainly have an external optical drive (CD/DVD burner) connected to your computer, or a USB adapter that connects an old internal hard drive or laptop DVD drive to a USB port.
Every peripheral utilizing the Universal Serial Bus standard requires a unique identifier string so the operating system can parse what it is and how to talk to it. Perform a full shutdown (not a restart)
If you are seeing this ID in Windows Device Manager, but you cannot access your files, you are likely experiencing a driver compatibility issue or a logical disk error.
