Angry "HL-340" usb to serial converter

Asked by caccolillo

Hi , I've a laptop pc (Joybook r23e BENQ) with no serial port , so I'd like to use an USB to serial converter .
I've bought one named "HL-340" but my UBUNTU 7.04 Feisty Fawn doesn't recognize it.Please does anyone knows how to fix this problem?
I need it to connect via "minicom" to an ARM board running LINUX.
I've tried the command lsusb which has produced the following output:

Bus 001 Device 016: ID 4348:5523

Can I fix this problem If I install a newer distro ?
Thank you very much.

Which port are you using in minicom? For USB to serial converters usually is ttyUSB0 or higher. If that one does not work try upgrading to Hardy.

As Theodotos mentioned previously, they are all typically added automatically to the first available ttyUSBX device. The kernel driver that runs them all is "usbserial", and typically they are all detected easily.

Run the following command to verify whether it was mapped to a tty device:

grep ttyUSB /var/log/messages

You should have output similar to the following:
"usb 6-1: pl2303 converter now attached to ttyUSB0"

If you do, then you're all set. If not, then you can load the "usbserial" kernel module manually using the information you specified in your post.

sudo modprobe usbserial vendor=0x4348 product=0x5523

If those values were in fact representative of your usb device, then check your /var/log/messages again to see if it yielded the appropriate results. If it all works and you want this module loaded every time at bootup, add the following line to /etc/modules:

usbserial vendor=0x4348 product=0x5523

Cheers.

Thank you to all , I've fixed the problem switching to UBUNTU 8.04.
It now support both the usb to serial cable and the video card (a Via Unichrome pro vga).
