I have a USB dongle from a wireless headset and when I plug it in, ubuntu starts malfunctioning: for example the icons minimize maximize and close from the program windows don't work, I cannot open things from the desktop, I also cannot right click it, the default left side bar does not work neither...
Sometimes it is possible to close some windows or to open something from the side bar but it seems to happen randomly.
I also managed to resize a firefox tab when it was supposed to be minimized. I could not see it but I think it was open anyway.
The problem disappears if I suspend and wake the computer up again. Then everything stats working like a charm.
What is going on and why it starts working again after suspension? Is some kind of process messed up when I plug in the USB dongle?
