Unlike plug-and-play devices, connecting the BC-96AC board before installing the driver often results in Windows assigning a generic, non-functional driver.
Simply put, a is a software interface that allows an operating system (typically Windows, though some industrial Linux variants exist) to communicate with a hardware controller bearing the BC-96AC chipset or interface protocol. Without the correct driver, the system either fails to recognize the device altogether or operates with severe latency, jitter, or functional gaps.
