112 module_parm_desc (delay_use, "seconds todelay before using a new device ");
Set delay_use to 5, while module_param is a macro provided by Linux kernel 2.6, so that delay_use can be set when the module is loaded. (If this parameter is not set, the value 5 indicates that a new device is waiting for a delay of 5 seconds .) Why latency? When the inserted USB
