XU4 CLOUDSHELL2 HDD USB2

Post by zlotyx » Tue Mar 13, 2018 9:31 am

Hello

I just start my odroid XU4, and I saw that when Im using samba I got max 38 MB transfer. I use WD RED 4TB, and router with gigabits ports.

As I understood it's connected to USB2.0 port (below show 480M), but I connect it to two port socket.
I suppose that somehow this port works as USB2. How I can change it to USB3.

It seems to be a USB 3.0 physical connection issue.

Please clean the USB 3.0 ports on the XU4.

If it doesn't help, the USB cable might have a problem.

This should not still be happening, I think the circuit board manufacturer needs to step up their game or give Hardkernel a discount for poor quality control.

Actually, we put the cleaning process on the manufacturing line from over one year ago.
We've also tested the USB 3.0 functionality with USB 3.0 storage devices in another testing process.
But I think still 0.5~1% of cables or connectors could bypass our screening process due to electrical/physical tolerance.
