Hi! I'm trying to figure how to make this weird usb dmx controller work... I cant find drivers for it anywhere and the device manager shows this

The hardware ids of the controller is this

the USB DMX512 is listed in freestyler but it gives an error
"DHC_OPEN - DHC_ERROR_NOTOPEN"

Im not sure what driver do I need to install. chips inside are sn75176bp and PIC16C745. not sure if that helps.

MAriance, were you able to solve the driver problem? All the links for this driver are down.
In Device Manager, it says "USB DMX512".
Mine uses the same chip and memory sn75176bp and PIC16C745.
