[Voyage-linux] usb serial port adapter not found

[Chad Phillips]

I am trying to add a USB serial port adapter to my soekries net4511 .  I 
have a pcmcia usb card.  It works fine, other USB devices run on it 
fine.  I plugged in a USB serial port adapter.  When I plug it in, 
nothing shows up in var/log/messages and the usbserial driver does not 
load.  If I do modprobe usbserial, I get this in var/log/messages

Dec  4 01:01:38 voyage kernel: drivers/usb/serial/usb-serial.c: USB 
Serial support registered for Generic
Dec  4 01:01:38 voyage kernel: usbcore: registered new driver

Dec  4 01:01:38 voyage kernel: drivers/usb/serial/usb-serial.c: USB 
Serial Driver core v2.0
root at voyage:/var/log#


If I try to use /dev/ttyUSB0 I get:
ar-2: /dev/ttyUSB0: No such device

Any ideas on how to get the adapter recognized?  I have done a lot of 
updates to my version of voyage, so it is very possible I broke 
something, but any ideas on where to look?  This adapter works fine on 
my laptop under Fedora Core 3.

thanks
