Will this work to power a usb hub for my nexus?
Ok, i have a OTG-Y cable to power my nexus 7 and a harddrive, but It seems that the hard drive gets so little power that it does not work if I have a usb extension cable or hub between it and the y-cable
So i need a powered USB hub, after much searching on ebay I can not find a 12v powered hub (car), so I should probably fix this myself.
So, what if i modify a normal usb cable like this on the picture so I can use another USB-power adapter to power the hub (and then harddrive, and other devices)
Will this work?
