Arduino MKR WIFI 1010 unable to connect

I'm trying to connect my MKR WIFI to pc via usb. I'm in the Arduino set up page every time I try to connect i get an unable to connect message.
On the MKR there is a green led illuminated by the cable and an orange flashing light.
Can anyone help.

Can I presume you installed to cores in the IDE as they also include the driver ?

Also that the cable you are using is BOTH POWER AND DATA as most are power only.
