Laptop's MINIPCI-E standard contains USB2.0 signal and 3.3V power supply. This product is to lead the USB signal out on the USBHUB chip and boost the 3.3V to 5V/1A to supply the USB device.
Because the USB signal is output from the computer, some computer screen shield this signal or no signal output at all, which will cause this card can not be used, not a card problem. If the inner bridge USB is damaged, you can't use this card either.
MSATA and Mini PC1-E slots look the same, before ordering, please confirm your motherboard is MINI PCI-E slot (generally inserted wireless network card). This product only supports Mini PCIE interface, other interfaces can not be used!
