Finding "USB to RS232" resources list

Hi,

I'm wondering how to get the "USB to RS232" device name, description and serial number, as NiMAX is able to do (please see the attached image NiMAX-USB-232.jpg).

Using the viFindRsrc function (as in FindRsrc_CVI.cws example) I get the resource name only: "ASRLxx::INSTR" (viFindRsrc.jpg attachment).

Thank you for any suggestion.
