Provided is a driver agent device for supporting a remote device driver development environment in an embedded system, in which a host system having a device driver development tool and a target system having a device driver are separated from each other and interconnected with a communication network. The driver agent device includes: communication processing means interconnected with the target system to receive and process various service requests from the device driver development tool of the host system, and to transmit the processed services to the host system through the communication network; core means for determining types of the services requested from the device driver development tool of the host system; and service processing means for performing corresponding services based on the types of the services determined by the core means. Thereby a device driver developer develop the device driver easily and quickly without expert knowledge on the embedded system and the device driver can be adapted to the target system and tested without complex procedures to effectively reduce time and manpower needed for the device driver development.
