Dominic Germain developed USB FunctionFS gadget support for the DragonBluep/openwrt repository, enabling OpenWRT to provision custom USB devices without requiring device-specific kernel modules. He implemented this feature by introducing a kernel configuration option that activates FunctionFS gadget capabilities, streamlining hardware prototyping and deployment workflows. Working primarily with Linux kernel development and embedded systems, Dominic integrated the new functionality into the OpenWRT build and test processes, validating basic usage scenarios and documenting the feature for future expansion. His work focused on Makefile and kernel configuration, providing a foundation for broader testing and further enhancements to USB protocol support in OpenWRT.
