My case doesn't support a USB 3.0 front panel so I decided to buy a USB 3.0 extension cable, one 2' & one 3' extension cables. I figure I'd run them off the motherboard back I/O panel to the front of my case for doing large file transfers via a USB 3.0 to SATA (SSD) adapter. The adapter works running straight from the motherboard: it's a 9" cable. When I use the extension cable, and plug in the adapter the drive doesn't turn on. I'm assuming it's not getting the power delivery it needs, possibly due to the length of the cable, but I'm not sure. Or possibly the cables are both bad, because the adapter to the extension to the motherboard doesn't work with both.
