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?

this is my lsusb command,

but in my dmesg, was not found.
check this out, (usualy there is another rows, just like “…converted to ttyUSB0…”)

regards :wink:

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,
