modem - usb to serial configuration

I have a serial modem connected to a usb port using an adapter cable. The system is a HP DL360. RedHat ES3.0

I am using the device /dev/ttyUSB0

When I issue the command "mgetty ttyUSB0" I get the following output in the log file.

How do I get the system to see the modem.

Hello jshoovie
1)The answer to your question is:
you can get the list from wwww.linux-usb.org .

2)Can you help me in configuring my USB->serial converter.

a) I am working on Fedora core 4(2.6.11).When I giv the insmod command, I get the following answer:
cannot find usb-serial.o

b)I downloaded cp2101 drivers CP2101x.RedHat8v1.1.tar.gz .It has 4 filesone of which is usbserial.o .Where to copy the file.

c) It is said the kernel 2.6.12 supports usb. How to configure or compile it with my kernel.(for hotplug support)

d) After plugging my cable and typing dmesg.The o/p is:
new full speed usb device using ohci_hcd and address 3.

e)But to configure under minicom , I did not find /dev/usb/ttyUSB0 port.
Do we need to make the usb0 node ourselves using
mknod /dev/usb/ttyUSB0 c 188 o
or is it existing already.

f)Anyone,Please help me.Please tell me step by step configuration with commands used.I am a newbie.
