    Abstract

    The CoolSand RDA (RDA Microelectronics) USB driver is essential for establishing communication between Windows-based development tools and RDA chipsets (commonly found in feature phones, IoT modules, and legacy mobile devices). However, the original drivers were designed for 32-bit Windows XP/Vista/7 and lack native support for 64-bit Windows 10, particularly due to driver signature enforcement (DSE) and deprecated legacy APIs. This paper documents a method to successfully install and operate the CoolSand RDA USB driver on 64-bit Windows 10, including disabling driver signature enforcement, manually installing legacy hardware, and verifying COM port enumeration. 🚀 Guide: Installing Coolsand RDA USB Drivers on
