3. Copy the 5 GB file from the drive to the laptop to transfer data in the USB 3.1 Gen 2 (10 Gbps) mode. Note that the actual
data transfer rate observed on the laptop may vary based on the hardware/software configuration of the laptop and the SSD
used.
4. Connect more drives (USB 3.1 Gen 2, USB 3.1 Gen 1, or USB 2.0) to other DS ports to check multiple types of data transfers
for a sample set up.

Issue
Possible Cause
Troubleshooting Procedure
1
Data transfer is not happening at USB
3.1 Gen 2 (10 Gbps) speed
The USB 3.1 Gen 2 SSD may not have been
connected to a USB 3.1 Gen 2 port.
Ensure that the SSD is connected to one
of the DS ports (DS1 to DS5) which
support USB 3.1 Gen 2 data transfer.
The SSD may be non-compliant with USB
3.1 Gen 2 standard
Ensure that a USB 3.1 Gen 2 certified
SSD is used.
Multiple simultaneous data transfers may be
happening which will result in sharing of the
USB bus bandwidth.
Stop all data transfers on the USB bus
except the one to be used for
demonstrating USB 3.1 Gen 2 data
transfer speed.
2
Detaching a mass storage device (USB
3.1 Gen 2/ Gen 1 / USB 2.0) from a DS
port while data transfer is in progress
causes data transfers happening on
other DS ports to stop
The Operating System running on the host
PC may have issues with handling device
detach events on USB
Check for the latest OS updates and
install those updates on the host PC and
check
