USB3 enough to power 2,5 external HDD?

Could you give mainline a go?
Sure, where can I get it?
New tests I've made:
I added a generic powered USB hub to the equation, no luck. It outputs up to 1000mA. The possibility that the drive is asking more than that is plausible. Hard Disk Sentinel says the drive goes as far as 500mA though.
I tried with a WD Easystore 4TB, which has it's own 12V Power Supply. Works like a charm with the Rock64's USB 3.0 port. Transfers are very fast and very stable.
I also tried the small WD Passport in the Raspberry Pi just to see the behaviour. Something similar occurs, the drive tries to spin but disarms when RPM increases. Same thing as in the Rock64, but happens even before real action occurs in the drive.
