This report provides a detailed technical analysis of the , a critical software component enabling host communication with the FS-SM100 data acquisition module. The driver facilitates high-speed serial communication over USB, implementing a proprietary command-response protocol. Key findings indicate that while the driver is stable for basic data logging tasks, limitations exist in multi-threaded environments and legacy operating systems. Recommendations include developing a cross-platform abstraction layer and updating firmware handshaking routines. Fs-sm100 usb driver
