How to Update Device Drivers Quickly & Easily. Tech Tip: Updating drivers manually requires some computer skills and patience. A faster and easier option is to use the Driver Update Utility for Prolific to scan your system for free. The utility tells you which specific drivers are out-of-date for all of your devices.
I am trying to connect minicom to a serial device that is connected via a USB-to-serial adapter. This is a PL2303 and from everything I've read no additional drivers are required. The device is recognised as a PL2303.
I'm a beginner at minicom. Is this the correct command to execute? Or do I need to configure something?

First check with
dmesg | grep tty
if system recognize your adapter.Then try to run minicom with sudo minicom -s
, go to 'Serial port setup' and change the first line to /dev/ttyUSB0
. Don't forget to save config as default with 'Save setup as dfl'. It works for me on Ubuntu 11.04 on VirtualBox.

You will need to set the permissions every time you plug the converter in.I use PuTTY to connect. In order to do so, I have created a little Bash script to sort out the permissions and launch PuTTY:
P.S. I would never recommend that permissions are set to 777.

The serial port communication programs
moserial
or gtkterm
provide an easy way to check connectivity and modify /dev/ttyUSB0
(or /dev/ttyUSB1
!) settings. Even though there maybe only a single USB to RS232 adapter, the n
designation /dev/ttyUSBn
can and does change periodically! Both moserial
and gtkterm
will show what port designation is relevant in their respective pull down menus when selecting an appropriate port
to use.Check out help.ubuntu.com/community/Minicom for details on

I had fix this with
adduser *username* dialout
. I never had this error again, even though previously the only way to get it to work was to reboot the PC or unplug and replug the usb to serial adapter.RomanRoman

I'm going through the same
hellish
experience here with a Prolific USB <> Serial adapter and so far Linux is the easiest to get it to work.On CentOS, I didn't need to install any drivers etc. That said,
dmesg | grep -i tty
ordmesg | grep -i usb
showed me /dev/ttyUSB0.screen ttyUSB0 9600
didn't do the trick for me like it did in OSX- minicom is new to me but it was complaining about lack of /dev/modem
However, this helped: https://www.centos.org/forums/viewtopic.php?t=21271
So install minicom (
yum install minicom
) then enter its settings (minicom -s
). Then select
Serial Port Setup
and change the Serial Device (Option A) to /dev/ttyUSB0, or whatever your device file is as it slightly differs per distro. Then change the Bps (Option E) to 9600 and the rest should be default (8N1 Y N)
Save as default, then simply
minicom
and Bob's your uncle.HTH.

I get get the same minicom error, 'cannot open /dev/ttyUSB0: No such file or directory'
Three notes:
- I get the error when the device attached to the serial port end of my Prolific Technology PL2303 USB/Serial adapter is turned off. After turning on the device (an embedded controller running Linux) minicom connected fine.
- I have to run as super user (i.e.
sudo minicom
) - Sometimes I have to unplug and plug back in the USB-to-serial adapter to get minicom to connect to it.
I am running Ubuntu 10.04 LTS (Lucid Lynx) under VMware (running on Windows 7). In this situation, make sure the device is attached to VM operating system by right clicking on the USB/Serial USB icon in the lower right of the VMware window and select Connect (Disconnect from Host).
Remember to press Ctrl + A to get minicom's prompt, and type X to exit the program. Just exiting the terminal session running minicom will leave the process running.

I had the exact same problem, and it was fixed by doing a
Peter Mortensenchmod 777 /dev/ttyUSB0
. I never had this error again, even though previously the only way to get it to work was to reboot the VM or unplug and replug the USB-to-serial adapter. I am running Ubuntu 10.04 (Lucid Lynx) VM on OS X.14.5k1919 gold badges8989 silver badges118118 bronze badges

I suggest that newbies connect a PL2303 to Ubuntu, chmod 777 /dev/ttyUSB0 (file-permissions) and connect to a CuteCom serial terminal. The CuteCom UI is simple intuitive. If the PL2303 is continuously broadcasting data, then Cutecom will display data in hex format

I just got my GUC232A cable with a molded-in PL2302 converter chip.
In addition to adding myself and br to group
dialout
, I found this helpful tip in the README.Debian file in /usr/share/doc/bottlerocket
:This package uses debconf to configure the /dev/firecracker symlink, should you need to change the symlink in the future run this command:
dpkg-reconfigure -pmedium bottlerocket
That will then prompt you for your new serial port and modify the symlink. This is required for proper use of bottlerocket.
I did that and voila! bottlerocket is able to communicate with my X-10devices.
