hedmo,
Look at dmesg after your cable is plugged in or look in dev for your new /dev/ltty entry.
You should get the /dev entry anyway but you will need to add kernel support for your USB to serial device before it will work.
Thats the ftdi_sio module.

hedmo,
Serial ports need to be configured. Your /dev/ttyUSB0 is no different.
You neet to use the same settings at both ends of the serial link.
Its actually RS485, whic is similar to RS232. RS232 is point to point only. RS485 does away with that limitation.
This document says you need te set up /dev/ttyUSB0 to use 1 start bit, 8 Data bits, 1 stop bit, no parity and a baud rate af 19,200.
There is really no standard settings but USB serial ports are rarely set as slow as 19,200 baud.
The software that sets up the serial port needs to run as root. Hopefully, WINE is not running as root, so it won't be able to make the setup to the serial port.
Thats inconvient.
What does show?

hedmo,
| Code: | | crw-rw---- 1 root uucp 188, 0 Jan 20 20:29 /dev/ttyUSB0 |
Add your normal user to the uucp group, then you and WINE, running as you can configure the serial port.
You need to log out and log in again to pick up your new permissions.
With those permissions and not being in the uucp group, you cannot use the device at all.
You will still need the symlink as the ubuntu forum shows.
