FAQ:Resuming from Hibernation; A beginners guide to Devcon
Windows not resuming from hibernation properly? Well this might be an answer for you. There is a utility from Micro$oft called Devcon that can disable and enable devises for you that should help sort the mess. Trouble is it isn't very user friendly and seeing lots of people struggling with it over on another thread I decided to do this tutorial. So grab your copy here and see if it helps you out. It is written for the complete beginner so goes through the absolute basics.
It isn't a guaranteed fix but if windows wont come out of hibernation or some USB devices don't work properly when it does then this is well worth a go.
Usual applies have a read through it first before you start messing about and if you still don't understand it then leave it alone as I am not going to be responsible if you break your machine, although it's unlikely.
Any questions, ask away and I will see if I can help you out.
Problem with Bluetooth USB stick
I have tried your solution but it doesn't seem to work.
After resume, the blue light of the stick is off ; I run the code with the right PID for my Bluetooth USB stick but I get a response that tell me that the device doesn't exist. Like it wasn't pluged.
I am obliged to unplug and plug the stick back to make it work.
