Hi, I recently bought a Yamakasi monitor and in order to use/power it, I purchased Apple's Mini DisplayPort to DL-DVI adapter (http://store.apple.com/us/product/MB571Z/A). Currently, I have the MiniDisplay and USB ends plugged into my MBP. It works fine, but I prefer it not suck up one USB port. On the adapter itself, the block has a USB female end. I hear people say that's for connecting to the iMac or Cinema screen's USB port. But because my monitor doesn't have an USB port, I'm not sure how to use the female end on the Apple adapter I tried using the iPad's 22v USB-wall plug with a male-male USB cable for that adapter's female end. That didn't work. Anyone have any other ideas on how to use the female usb end on the apple dl-dvi adapter?
