Re: Ubuntu USB-Serial port install procedure
Over internet (IP network) is different from over a serial port. What are you trying to achieve (connect) with that pl2303 converter ?
↧
Re: Ubuntu USB-Serial port install procedure
Have managed to get it connected and working now... Although it does not show "DE IONOSPHERE : CONNECTED as it does on the Windows platform....
I tested it with another laptop... and also made a couple of contacts across the world, so happy chappy now...
Thank you for the guidance on this forum... Much appreciated.

Re: Ubuntu USB-Serial port install procedure
Hi!
I tried all that and finally see:

[ 7550.063931] usb 6-2: pl2303 converter now attached to ttyUSB0
But in my application (which is running under WINE) it always says s.th. like "couldn't find serial device COM1". The application is then looking for other COM-ports, but ends up with USB-Serial-Adapter out of function.
The adapter is definitely working, because I also use it in a Windows XP environment.
Does anybody have an idea?

Re: Ubuntu USB-Serial port install procedure
I hope this forum is still alive. I just found this and have followed the procedure for installing Prolific USB to Serial Adapter very carefully several times with mixed results. Usually when I do this the serial port does't work. The messages I get at end of dmesg are:

The difference seems to be that in the later case that works, the specific pl2303 is detected where as in the case above it's just a generic version of usbserial? Anyway I can't figure out why sometimes I get the later but most of the time I get the former.
Also, I have the statement usbserial vendor=0x067b product=0x2303 in /etc/modules but even when I have the port working (case 2 above) the change is not persistent across reboots and I have to start all over again.
I would really appreciate someone pointing out what must be obvious but that I can't seem to overcome despite many hours of work.
Thanks in advance.

does anyone know how to permanently change permissions for /dev/ttyUSB0. Mine keep reverting back.
Don't do that. Just add your user to the dialout group so you have appropriate permissions on the device. Try something like:
sudo usermod -a -G dialout $USER(in Ubuntu or Debian, this may need minor changes in other distributions).

Does anyone know how to set the speed for a usb -to serial port?
stty -F /dev/ttyUSB0 9600should set /dev/ttyUSB0 to 9600bps.
In other words, this works exactly like any other serial port, you can set its speed using stty. Once the device is visible to the system, applications (including stty) do not know or care whether the serial port is a virtual one over USB, or any other low level hardware details about the way the device is implemented -- the driver and the kernel hide all that from applications. That's how Unix/Linux is supposed to work.
To see if setting the speed worked, use
stty -F /dev/ttyUSB0 -aand you should get all the details of exactly how that serial port is currently configured, including its speed.

What are you trying to do and which applications do you use? I'm using Ubuntu as well and there were no installations for the serial port necessary.

I bought a new phone having the modem ct800p . I wanted to connect that modem to linux debian or ubuntu. I had tried my level best for configuring the modem as per the above method, because my modem was not recognised as a ttyUSB device in the /dev/ file. All my efforts went in vain

I bought a new phone having the modem ct800p . I wanted to connect that modem to linux debian or ubuntu. I had tried my level best for configuring the modem as per the above method, because my modem was not recognised as a ttyUSB device in the /dev/ file. All my efforts went in vain

Re: Ubuntu USB-Serial port install procedure
Your log quote looks good. Is the new device appearing in /dev/ ? It's name should be tty.usb.something.

Re: Ubuntu USB-Serial port install procedure
Thx for the tips. For Ubuntu 10, I just plugged the device and everything was there. Just needed to use dmesg to make sure it's there.
