Just read my reply and it might cause misunderstandings, it was on use by the web program, a notification saying it's available and is on use. Only problem was I wasn't getting any permission request to grant access. Terribly sorry for my English!
It's stuck on connecting....
It says please authorise the connection on your device but I'm not getting any permission request. I've enabled usb debugging, I'm using Huawei y9 prime as well. I'm trying to grant dump permission but idk what's my issue. I'm kindly asking for assistance
