He it is a portion of log

What coult be wrong? Any idea what to check?

I could open /dev/ttyUSB0 and seems to be recognised without problems

dmesg output:

According to the log the stick does not repy to init commands.

Make sure the port is not used by some other program.
Also try the stick on another port.
Are you sure the stck works on another Linux machine?

Also try to unload pl2303 module and load it back - sometimes it helps:
modprobe -r pl2303
modprobe pl2303

I have tried same device on Windows and get same trouble. So as you mention it seems a problem connecting to stick? Is there any way to check if its working properly sending som commands?

Did it worked once? May be it is boken/damaged? Exchange it in your shop.

It never worked. No under windows no under linux

It seems to be damaged.
