I am using the blue one (PL2303-Prolific) as well and from what I found from the net, there is issue with driver. I am not able to make it work on windows. However it works well on Ubuntu 16.04, here are the instructions:
- connect the serial adaptor to usb port of the Ubuntu machine.
- install minicom in linux machine:
sudo apt-get install minicom
- find the usb port that serial connect to:
dmesg | grep pl2303
- the output of step3 would indicate which usb port
[ 6.804403] usb 1-1.3: pl2303 converter now attached to ttyUSB0
- change file permission to allow minicom to save config using ttyUSB0 as an example
sudo chmod 755 /dev/ttyUSB0
6.run minicom
mnicom -s
- from the config menu, select “Serial port setup”.
- press “A”; update A-Serial Device: to what you see in step4. It would look like
A-Serial Device: /dev/ttyUSB0 - hit “enter” and then press “E” to select “E-bps/par/Bits: 115200 8N1”
- hit “enter” and select “save setup as dfl” and select “Exit”
If everything goes well, you will see
“Welcome to minicom 2.7
Port /dev/ttyUSB1”
