Get jtagtest, install it. Run JTAGTest.exe. Window icon is "generic" (not defined in application) Choose Help > About. Close the newly opened dialog box. Now you can see different icon (a chip) on the main window
It seems that everything was working fine on Wine ver 1.0.1 (version installed on fresh Ubuntu).
