Help with USB to Serial adapter please.

[GaryL]

Hi all

Just been messing about with a USB to Serial adapter that I had knocking about.
But my Bubba doesn’t seem to recognize it on boot. Do I need to enable something?

Bubba’s dmesg output:

Code: Select all

garyl@bubba:~$ dmesg | grep -i usb

Any ideas on if and how I can get my usb-serial adapter to work with my Bubba?

Looks like you have a plajn PL2303 based adapter. And that should work.

You must however install the extra kernel modules, instructions here http://excito.org/forum/viewtopic.php?t=452

After that remove and insert the cable again. The device should show up as /dev/ttyUSB0
