Latitude E6520 Docking station USB problem

Hello there,

I dont really belive that anyone is abble to help me fix this problem but ill give it a shot coz this is reallt weaird and annoying.

So i am using an docking station to my dell, it has 5 USB ports (3 on the left and 2 on the back).

Now i am using a logitech wireless mouse. Whenever i plug the usb mouse receiver to any of the left ports, it works just fine. If I use any of the 2 on the back, it lags as hell and it seem to get stuck in every procces action, like moving files over explorer etc.

But thats not the most anyoing thing im expiriencing...

I wanted to make my life esier, so i bought a mini-pcie usb adapter, this one: 

And i plugged my mouse receiver to it- it works great! BUT WAIT, only if laptop is not connected to the docking station! If it is, im getting the exact same problem as i would connect the mouse receiver to the back of the docking station...

I tried reinstalling the root usb hubs but it havent changed anything. This is weird as hell.

I would really aprichiate if someone could help me with this problem. rly.
