Joe,
What device does "dmesg" show (output) when you plug in the USB
cable? Also, are you root or sudo when you configure minicom because I
don't think it will write the config otherwise.
Once you know the dev name (i.e. ttyUSB0 or ttyUSB1) try this
from the console window to find the exact path to the device.
`find /dev -name "ttyUSB0" -print`
(NOTE: Do this command with the name given by dmesg in the quotes.)
Also, just an FYI, you can get puTTY for Linux.

Subject: [brlug-general] USB serial console woes
Hey guys.
I installed Jaunty Netbook Remix on my netbook this morning, and it's
great.
I want to configure Cisco switches with it. I "made" a USB console
cable that I've been using under Windows, and it works great. Windows
sees it as COM3, I point PuTTY at COM3 and I'm golden.
Under Ubuntu, it's not working. I can see that the cable is recognized
as ttyUSB0. I'm running minicom at 9600, 8N1, and pointing it at
/dev/ttyUSB0. But all the screen does is flash. I press Enter and get
nothing. well, on this site
[http://www.cromwell-intl.com/tcpip/switch-programming.html] I see
that it says to use /dev/usb/ttyUSB0. So I set it to that, and it
still flashes constantly, but when I press Enter, I can see the
hostname of the switch for half a second before it flashes and is
gone.
Interestingly, when I open minicom with the config file that points to
/dev/usb/ttyUSB0, it says there's no such device.
What am I doing wrong?
Thanks.
Joe
