USB to serial convertor + minicom

I have RHEL4 with kernel-2.6. I have a USB to serial convertor FT232R cable.this cable is used to send data to a device used as temperature is working well in windows.i have to make it working in linux with kernel-2.6.
RHEL4 already have pl2303.c and pl2303.h files in /usr/src..../drivers/usb/serial/pl2303.c so i did the step
1...modprobe pl2303
2...lsmod shows the loaded module and dmesg also confirms it.
when i use command
...dmesg | grep usb
it shows /dev/ttyS0.....not ttyUSB0.
can someone tells me that these both are same?

also minicom doesnot do any work when i open it....pls help me

I have a problem understanding what you say.
To me it seems impossible that the command
dmesg | grep usb
will return anything other than lines containing the string "usb"
That command could not return /dev/ttyS0 as an output.
