In my case 'lsusb' told me the device is 0930 0225, so Thank you ccerrillo this solution is working fine on my laptop. I spent over a pair of days (and nights) with no success trying to make working the integrated Bluetooth on my Toshiba Saltellite L50d-B-12W when I found this post.

It is still issue for dell user as disabling and doing further steps like this does not give us flawless experience.

I have just tested before posting or commenting this. if you uninstall without disabling it at least didn't work me for me. Step 2 must be done and that is disable it. Your bluetooth icon should reappear and the failed device should be gone. use your trackpad to go to action menu at the top and click 'scan for hardware changes' Right click and click DISABLE.Ĥ.Then right click the ' intel usb 3.0/3.1 extensible host controller' and uninstall it.ĥ. This solution is might not be permament because the problem might come back but it is pretty much a driver issue i think But at least you dont have to restart which take time (if no ssd user)Ģ.Click the double Usb Serial Bus controllers at the bottom (or just one click the arrow at left)ģ.Now you should see the device descriptor failed device with caution mark. My bluetooth adpater brand QCA9377 which most are having this USB descriptor issue and bluetooth icon missing.

I have gotten a strong solution that requires no restart provided you have the correct driver installed It could be driver or windows problem.įor those who is having this annoying issue specially dell laptop users like me.

I did everyhting in the net solution since it is not a dell laptop issue. I bought the new laptop inspiron 3593 but already have this annoying bluetooth disappear from device manager and no switch button for arching the net i found majority have this issue specially those who have qca9377 in particular
