Well, currently I configured it as part of kernel instead of module..... :-(
But anyway, if on an embedded device, there are only limited device nodes, how to tell the kernel to release the device node when a usb storage device is disconnected? Obviously in kernel, usb driver knows when a specific device is unplugged and scsi driver knows a sd unit is detached, so is there any way we can release the specific device node and reuse it next time?
