No USB Devices

Hi together,

i have a problem using VirtualBox 4.3.12.
I can´t add USB devices in my VirtualBox settings. Any devices i tried to use are working on my computer(I am using Win7 prof. 64).
A few weeks ago it worked fine, i don´t know what happened wrong. So i updatet to 4.3.20, but when trying to use this version i can´t start one of my guest systems, there appears an error that something crashed. After searching on Google i was told to use the older version.
What is the problem for this? May be a windows update?
I hope somebody can help me to get my USB devices work again in my guest systems?

Thanks in advance and a merry Christmas,
Oliver

Make sure the right extension pack is installed. The extpack version must match the VirtualBox version.
