Laptop slowing down when gamepad is connected

[Greyfalcon]

Hello,
I am running Win 8 on my Lenovo E50 laptop. My laptop slows down whenever I connect my usb gamepad/controller. This only happens when my laptop is connected to the internet. I have wired broadband connection. So whenever i have my Ethernet cable connected to my laptop and then connect the USB controller, my laptops becomes slower than a snail.

Note that this does not happen when only the controller is plugged in. It happens only when both the things are connected. So is I have to use the controller i have to disconnect the ethernet cable

Now i know that this laptop is pretty low-end, but still i don't think a usb controller should slow it down so much.
Can anyone please tell me how and why this is happening?

Thank You

I've found a post from about 20 days back; http://www.tomshardware.com/forum/40897-63-whywould-device-windows-slow-down

I'll only list one answer because the posts on there are massive, hope the link and another guy's answer below helped you.

Might be a poorly coded driver for your chipset or for the device. Try updating both the USB controller and USB device drivers and see if that helps.
