FTDI USB port

怎么解决寻求帮助ERROR - Failed to Open FTDI USB port. Make sure to select the right cable type.
If you have not installed the FTDI Windows USB Driver, follow the instructions in the Programmer Help topic:
"Installing/Uninstalling Parallel Port Driver and USB Driver".
If you have installed the driver, if you recently plugged in the cable, please wait a few seconds and try again.
This will give the operating system time to recognize the cable.

根据问题，你是没有安装ftdi的usb转串口的驱动！
