Topic: DIR-825 Extra USB Port?
I opened my dir-825 and found out that there is extra usb port. even I never soldered in my life, I want to try. so I cut one usb line and soldered the line with extra port. but when I connect the line to external usb harddisk(with no power), the power turns into the hdd but system cannot catch the usb port differences. Maybe I made a mistake when I soldered so the hole was broken or is not connected. For those who want to try himself, I am putting few links that I looked.
First, the picture of the router(on right down, there is one unpluged usb port)
Second, Usb cable schematics.
If you success the plug-in, please post it here!
