ADB unauthorised


Just installed a fresh install of the Debian Buster image, and i’m trying to connect via adb to continue setup.

However ADB doesn’t seem to want to connect - i can see a “meson” adb device in device manager, but ADB wont connect.

it it try chrome://inspect/#devices
it sees the device, but gives the following message
Pending authentication: please accept debugging session on the device

Not sure how i can accept debugging on the device, without being able to connect to the device ?

Any suggestions would be appreciated
