Generally speaking, hot-plugging devices/sensors onto the GPIO pins of a running Pi is a potentially device/Pi damaging bad practice. But does that hold true for a PL2303TA chipset-based USB to TTL Serial Cable? Like this. Since one side is USB, is there some sort of power sequence inherent within USB that might make this a safe practice?
Like maybe plug the GPIO pins first then plug in the USB to my PC.
The reason that I want this is that, sometimes when my Pi's lose Wi-Fi connectivity, my network detection/restart scripts on the Pi are unsuccessful in restarting the Wi-Fi connection. This leaves me without a way to log into the Pi.
