rs232 (usb to serial) cable not detected, why?

any suggestion about my problem, a few day ago i have checked my application and make rs232 cable converter to communicated it. And not detected, why?

FYI,
this is my lsusb command,

thanks

So, I have one of these inexpensive devices, perhaps the very same one, but it does show up for me.

lsusb (for only serial/USB adapter)
Bus 002 Device 003: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
dmesg | grep tty (for only serial/USB adapter)
[12591.384983] usb 2-1.7: pl2303 converter now attached to ttyUSB0

Perhaps it is an adapter gone bad? Or, perhaps it is a kernel version issue? I have updated to kernel 2.6.38-rc4, though I doubt you need one like that to use the adapter. On this computer I am still using openSUSE 11.2 as well. Tell us about your openSUSE setup.

Thank You,
