hi yes i have had this problem here is how i solved it for me
1. go to control panel
2. open system management
3. open devices
4, on the top of the window left hand open "show hidden devices"
5, is there a red cross next to anything? if so go to properties and uninstall driver
6. go to the tree where it shows all the usb devices and uninstall there drivers
7. now reboot windows (windows will reinstall the drivers automatic on boot up make sure you are connected to the internet in case windows searches for drivers online for you)
good luck
