The drive works fine if it's attached to a laptop, so the problem is with rock pro 64. Does anyone know if it supposed to power it up - in other words, should it deliver enough power to power up external USB drive (2.5 inch SSD) like a laptop does?
Rock pro 64 does have on board sata power connector that is used to power sata drive connected through the PCIe x4, so I believe it should be capable of powering a USB SATA drive - but this is just a speculation.
Both USB 2.0 host port provide up to 650mA and USB 3.0 host port provide up to 900mA. Once over this current limit, the regulator will cut off the USB power to protect the board stability. If your USB SATA drive withdraw current more than the above limit, please provide power to your USB SATA drive.
