Call:

It is simple. After it is disabled, the closed adapter cannot be found in the system. It is very clean! However, the premise is that the WiFi interface driver (My hsmmc0) must be able to work normally, my hsmmc0 is because ch0 does not detect the foot, which leads to the insertion and removal of the Wi-Fi module.
