Review: At first, I just connected everything at once. This didn't work at all for me. I plugged things into the front of the PC & nothing happened. I submitted a return request before I saw another reviewer saying you need to connect things one at a time. So, I mounted the board & connected it to the USB header on the motherboard first. Then, I connected the front panel connector. Finally, I connected the card reader module
Other buyer review: My machine is
Windows7: Boot with this plugged into the motherboard header. After boot is complete plug in the device to the USB header with nothing else attached. It will then load the driver for the extension. Afterwards plug in first additional usb device and allow it to load the driver then plug in the second usb device. This worked fine for me.
