hey guys im running a hp probook 470 g1 on windows 8.1 64bit, when i plug in my device it shows as an unknown device, tried using a usb 3.0 powered hub aswell still no luck.
my usb controller is the intel 3.0 usb extensible host controller - 0100 microsoft
intel 8 serries / c220 usb ehci 8c26 & 8c2d
i tried forcing the win7 drivers on this guide http://www.herculesdjmixroom.com/nl/forum/en-hardware/018795/ which leads to this link http://plugable.com/2012/12/01/windows-8-and-intel-usb-3-0-host-controllers
but when i reach the step where i have to look for an unknown device under other devices, it doesnt show up, it just shows an exclamation mark on my usb extensible host controller
please any suggestions
