stlink-v2-1 not working

I received my discovery 746 board The demo works fine , but now I want to download programs , but it doesn't work at all With the demonstrator GUI I always have this error : Unrecognized device ...Reboot board and try again I have upgraded stlink v2-1 to latest software (and this works fine ...)

Does anybody know what could be wrong here ?

Thanks Ronny
