Hello everyone

I am using UART to USB serial converter through using FTDI chip.

I am using FTDI232R chip to send AT command to a microcontroller. In one LattePanda the reply is instant as expected and in another one the reply came maybe one second later even with the same microcontroller.
When I installed the "Firmata Standard", the slow LattePanda became fast as I wanted it but when I rebooted the LP it went back to have slow serial USB communication.
I used the original WIndows10 home edition.
Any idea?
