LPC55 USB

[Zhang_123]

I am based on the LPC5502 keyboard and mouse design, but currently in the process of working with the PC if I keep operating the keyboard, and at the same time unplug and plug in the USB, the LPC55 will not correspond, have we encountered similar problems? How to solve it?

There are examples of USB usage in the SDK https://mcuxpresso.nxp.com/en/welcome.

Could you be clearer, I don't understand very well the procedure you are doing, and it is not clear to me about the programming problem, are you using an example of the SDK? are you using a custom board?

Does our LPC55 series have hot-swap related routines for USB and re-plug them during operation?Thaks a lot！
