Why USB 3.0 doesn't work?

I have using the USB 3/0 HDD and pendrive everyday and works well.

What type of USB 3.0 drive that you plan to attached? Please make sure that your device doesn't draw more than 900mA current.



----------------------------
The problem appears when i switch  usb2.0 (bluetooth keyboard) and usb3.0 hdd.

When i connect both in usb2.0 everything works fine.

thanks

I have this issue as well. Earlier I had posted that I was having issues with my Rock64 4Gb board being very sluggish in Lakka and Android. It is my USB 3 port causing it, but mainly in conjunction with USB 2. If I only use USB 3 with my 4-port hub and plug everything into that, it all works perfectly. Things run very smoothly. But as soon as I plug in a USB 2 device (controller, flash drive, etc...) my Rock64 board gets extremely slow and laggy. 

Likewise, if I plug in my USB 2 4-port hub and plug everything into that (including anything USB 3) my Rock64 runs very smooth. As soon as I plug in a USB 3 device in the USB 3 port, it gets very laggy. 

So, like this:

USB2 in correct port: works
USB3 in correct port: works
USB2 in USB3 port: works
USB3 in USB2 port: works
USB2 in correct port + USB3 in correct port: lags system badly
USB3 in USB2 port + USB2 in USB3 port: works (Because all ports act as USB2 now)

I genuinely don't know what's going on here. It happens only in Android and in Lakka, but these are the only operating systems I've tried. I don't remember having this issue on previous builds (non-rooted) of Android, but I also haven't gotten around to trying an older build yet. 

Build info:
Rock64 4GB board w/heatsinks and fan
Rock64 PSU from Pine64
Android on 32Gb eMMC
Lakka on SD
Physical switch for dual-boot purposes (saves having to remove the jumper!)
Modified Raspberry Pi 3 case w/fan

Things I've tried to troubleshoot:
Single booting each OS
Removing the USB hubs from the picture
Several different USB2/3 cables and devices
Removing the fan from the GPIO power pins

Things I intend to try and will update later:
An older build of Android
A different Linux based OS from Lakka
