The USB 2.0 (HS) ADFU Device is a type of USB device that likely uses the USB Device Firmware Upgrade (DFU) protocol. The "HS" stands for High-Speed, meaning it operates at USB 2.0 speeds (up to 480 Mbps). The ADFU part refers to the Application Device Firmware Upgrade protocol, which is used to allow USB devices to update their firmware directly over a USB connection.
In many cases, ADFU is used by devices such as microcontrollers, embedded systems, or peripheral devices that require firmware updates or configuration changes via USB. This protocol is typically used in scenarios where the device's firmware can be upgraded without needing specialized hardware programmers.
