You can take a look at the openusb_get_device_data() API. This function 
will return strings of LANGID=0x0409(US English). If you want to get 
other langid strings, use the openusb_get_raw_desc(). In testopenusb.c, 
you can also get an example(convert_string function) of converting 
unicode strings.
