Altair Technologies disclosed that Bitmain recently pushed new firmware to the Antminer series that will disable the microUSB interface of the control board after the update, affecting multiple Bitcoin ASIC miners including the S19k Pro, S21, S21 Pro (first discovered on the S21 XP). The interface was originally used for flashing third-party firmware and device system recovery. After being disabled, it will significantly increase maintenance difficulty and restrict miners' independent optimization of mining machine performance and power consumption. Altair recommends that if the device is running normally, one should be cautious about upgrading this firmware to avoid increasing operational risks and dependence on the manufacturer's official support.
