Since 1 week I am bearing with a nagging issue: " Unknown device under Universal serial bus controller in device manager" with a yellow triangle. I performed these steps:-
1. Tried Updation via on line search but showing "the best driver is already installed".
2. Tried Updation via " Browse My Computer for driver software but showing Code:43 error"
3. Tried uninstalling but with every restart it automatically came back with a notification" Device Driver Software is not successfully installed"
4. At last I went for formatting my laptop hp "dv4-2106tx" but the problem is still there.
5. I also tweaked battery power option advanced settings but no result.
6. Windows updation could not resolve this issue.
I need to get rid of this nagging issue. If any body want to have a remote access then i am also ready.
