But they were all labelled as 'Unknown USB Device (Port reset failed)' And funny enough, there were three yellowed devices under USB controllers, probably representing the three things i had still plugged in three of the USB ports. So with all those USB things still plugged in, i uninstalled the USB controllers again and reinstalled them again using scan hardware changes option. I plugged in my mouse, keyboard, pendrive etc but nothing happened. And after scanning for hardware changes, the drivers installed themselves back. In device manager, I uninstalled everything under Universal Serial Bus Controllers. The tutorial said to uninstall all USB controllers and install them again. I read somewhere that the reason USB bluetooth isn't working is because of my USB controller problem. I even tried disabling the PC one and reinstalling the USB one but problem stayed the same. And no bluetooth setting ever opens from control panel. Both bluetooth drivers (the one in laptop and the one in USB) get installed again, but with same yellow mark on them. So i uninstall all bluetooth drivers and check for hardware changes. except, they too show this yellow mark and same error code. I plug in the dongle and all its drivers are installed automatically. I think, okay maybe my bluetooth hardware is doomed so i purchased a new bluetooth USB dongle. I go its properties and it shows me 'Code 10' - Couldn't start the device' The bluetooth is detected again and automatically installed, and few moments later the yellow mark appears on it again. I uninstall it and check for hardware changes. So I open device manager, and there it is. I could keep clicking it all day and nothing happened. There was the 'Change Bluetooth Settings' but clicking it does nothing. So I went to Control Panel and searched for 'Bluetooth'. And my phone doesn't discover my PC bluetooth either. It shows that it's searching and dots running but no new device is searched. No icon in the taskbar, and although if go to charms bar and open ' Change PC Settings', there is a ' Bluetooth' entry under ' PC and Devices' but all it shows is the devices i once used to use from two years ago. And I realised my BT doesn't work in laptop. It kind of stopped working a year back and since I never used it anyway, i never looked into it much.Įxcept few days ago i purchased bluetooth headphones. Hey Dell, been a long time since I posted here because I had no issues for over three years with my Inspiron 7720.
