I own an Asus UX31A laptop, equipped with 2 USB 3.0 ports. I would like to connect several USB devices to one of these ports, using a USB 3.0 hub.
1) Am I correct in assuming the Asus "USB Charger+" commercial blurb corresponds to the USB 3.0 standard "Battery Charging Specification 1.2", and furthermore inferring that the laptop can deliver 1.5A through a USB port?
2) Does a powered external USB 3.0 hard drive draw on the USB power lines?
3) I would like to connect the aforementionned drive, an android phone, and a 200mA rated optical mouse to an unpowered USB 3.0 hub, itself plugged into the laptop. Should my above assumptions be false, would this setup be able to power all three devices?
Thanks to the usb guru who'll settle my fears to rest. Best regards, Sébastien
