摘要：
A method and system for transferring a firmware file between a host system and a device driver, wherein the host system includes an operating system segmented into a user space and a kernel space is disclosed. Aspects of the exemplary embodiment include using a first type of process file system command in the user space to initiate a transfer of the firmware file between the host system and the device driver, wherein the firmware file exists in the user space and the device driver exists in the kernel space; and using a second type of process file system command in the user space to transfer the firmware file between the user space and the device driver in kernel space.
