The driver \Driver\umbus failed to load for the device Root\UMBUS\0000.
Have this and many others that are sparatic. This happened yesterday at 3am and today the same time. The only difference is that today my keyboard stopped responding after i logged in. I tried to reinstall drivers. The synaptics driver fixed the mouse until today. Also i did a install over XP, and i think that this may have caused it. The problem is that if i reinstall my keycode will not work. it is MSDNA grouo keycode from the college. Any ideas? Currently in safe mode on the computer being affected. It is a Asus G50Vt -X1
EDIT: I had Win 7 64bit, and that is what i installed when this acted up, installed before and did a complete format and never had any issues so i believe this is what is causing it. So i guess i will suck it up and reinstall 7 and just go through the reactivation process.
