You need to authorize your computer on the device. Do you have a confirmation dialog?

Check:

adb devices

(it's related to adb, independant of gnirehtet)

This is a problem different from "unauthorized device" on adb.

IIUC, you don't get this popup:

Unfortunately, this is a recurrent problem. Some devices require to "authorize" the app manually, but each in different ways. See for example: #161 (comment) and #150 (comment).

I need to do something to avoid this problem…

Should be fixed by f868180.
