Most JP108 adapters ship with a mini-CD. If you don't have one, search for "RD9700 Driver" on reputable driver databases like DriverScape. Manual Update:

5. Common Hardware Defects

Before downloading any driver, you need to understand that "JP108" is a product model number used by various generic manufacturers. Nearly all JP108 adapters are built around one of two core chipsets:

• No signed driver for Windows – The included CD driver is often unsigned or uses a leaked certificate. This is a security risk (potential for malware-laden “driver installers”).
• No firmware updates – Vulnerabilities (if any) remain forever.
• Traffic is not hardware-accelerated – All packet processing is done in software via USB bus, making it easier to sniff/intercept on the host side.

Realtek

typically uses (e.g., RTL8152B) or ASIX (e.g., AX88772) chipsets, which are widely supported across various operating systems: Plugable USB 2.0 10/100 Ethernet Adapter
