I there I found issue with the verison of fedora. The USB very poor soltuion if I use the USB to wireless stick I get in Troubel after uodate from the internet it works. Better is to enable the USB Hub in the bios.
The VGA driver fail after return from sleep(standbymode)
You can ceover it change the resolution manul bag to normal one.
To be honest on opensuse 16.1 that no problem. As well on MX 25.2
