FRDM-KL43Z usb connection problem
Hello guys!
I have trouble with my mbed board. First I make my own board based on FRDM-KL43Z. Only different thing is including something more (like RS323).
BTW, here is my problem. 1. FRDM-KL43Z board has two USB connector. And my board also has two. PC is acktive when connect to MCU usb but sda usb isn't. 2. I try to install serial driver. But it can not install with "No mbed Microcontrollers were found" message. I connected it properly.
Guys! please give me some advice!!

The DAPLink chip on the board is responsible for mounting the device as USB mass storage and providing serial. Do you have a DAPLink chip populated and running the right firmware for KL43Z? See https://github.com/armmbed/daplink
