[] USB not set to correct speed

This is a part of the output of the lsusb -d <vendor:product> command:

 
...
SuperSpeed USB Device Capability:
    bLength                10
    bDescriptorType        16
    bDevCapabilityType      3
    bmAttributes         0x00
    wSpeedsSupported   0x000e
      Device can operate at Full Speed (12Mbps)
      Device can operate at High Speed (480Mbps)
      **Device can operate at SuperSpeed (5Gbps)**
    bFunctionalitySupport   1
     Lowest fully-functional device speed is Full Speed (12Mbps)
...

I’m fed up with transfert rates less than 20 MiB/s… (5Gbps → must have something around 600 Mib/s)… question is (as the seagate must be superspeed 3.0 compatible as seen in the specs) HOW TO set USB to superspeed mode ?

Hi
Does the system have USB 3.0 ports?

Here I see;


lsusb -t

You are right, those chipsets doesn’t deal with usb 3.0, I was thinking blue connectors were 3.0 but that means nothing if the motherboard doesn’t handle it.

In a short term I will replace the motherboard.

The chipsets I have are

  • Northbridge: AMD 760G
  • Southbridge: AMD SB710

…the southbridge is only 2.0, that’s all.

I got a PCIe USB 3.0 card for my PC, easier and cheaper than replacing the motherboard. Prices range $20 - $30 for many of them.
