Bluetooth has stopped showing in Wireless Radio on my T430 running Windows 7 Professional SP1, and Bluetooth can't be turned on. All Bluetooth Windows services are started. In Event Viewer, there are numerous Event ID 5 - BTHUSB errors: The Bluetooth driver expected an HCI event with a certain size but did not receive it.

Bluetooth was working fine yesterday (Nov. 3). I haven't installed any new software or done a Windows update since Oct. 30.

Have a look at Network Adapters in Device Manager. Any errors flagged?

No there wasn't, but there was an error either in System Devices or USB Controllers. I did a complete shutdown last night, not just a reboot, and Bluetooth was back this morning, so all's good. For now. And whatever error was there last night is now gone too. Yes, indeed it is odd. Thanks.

Always a good idea to do a complete shut down. Good to know it is working again.
