Since there is a native linux application you could use strace to check what it does.
Good idea
When you said that only the first command works you were testing in wine?
Yes
By "works" you mean it sends and gets a response?
Yes, i used sharkwire to see if something go in usb port and for the 1st command 'get_baud_rate', there is a message to and from the port. After that nothing until the 'write' command (which freeze the device).
