The USB port can still charge a device per BC. The steps are as follows: Step : Primary detection to determine if the port should be in SDP, CDP, or DCP (Refer to Table and Figure ). PD (device to be charged) sends out a V pulse on D+ and waits for a similar pulse from the USB port on D- .

Prevent these as much as possible by protecting your electronic components and boards from ESD. It's also important to note that there are many diode parts and chips out there to help protect inputs and outputs on circuit cards against ESD. ESD Protection.
