So my problem is (which I'm sure none of you have figured out yet) it doesn't work....yet.
This device has three connection cords for the motherboard: SATA, Jusb1~3 En-17 (?), and firewire. My particular motherboard does not support firewire so that cable is just chilling alone like most of us in our early years. (totally jk, please take no offense) So I have the other two plugged in the correct places (97% sure, lol)
and the green power indicator is on and my device manage recognizes and says it is functioning properly but when I go to deflower the slot with my huge 4g SD card (joke) nothing happens. I've tried restarting my computer with the card inserted and still nothing. The reader itself did not come with any software for the install so I figured it must be incredibly easy, and nope I was wrong.
Please for the love of (insert proper term here) help me!
I looked at the picture of your device. It is a very fine one, and I have a similar card reader in my home built computer.
The two USB cables should be plugged into the USB pin headers on your motherboard. The third cable (firewire) is for firewire capability in your card reader. Since your mobo doesn't have firewire, leave this alone (just as you did).
If you have Windows 7, it will download the necessary drivers and get the card reader operational.
