Glad to read you fixed your cable issue.
Anyway, for people experiencing the same issue, they are known as FPC cables and can be found over internet. You can also ask Arturia support for sending a cable.
now the problem is....my Mac and MMC does't recognize the BSP
Are you sure the USB data +/- cables are well welded?
Have you tried with a software recognizing MIDI (except MCC)? You can try "MIDI Monitor".
Have you tried on a PC using Windows? (or Android or IOS using an USB OTG cable)
