USB 3.0 is the latest technology providing more speed than USB 2.0. Windows 10 often slows down the performance of USB 3.0. It is often because of the un-supported USB 3.0 device or un-supported 3.0 connecting cable. You need to check for a few things when troubleshooting the USB 3.0 ports.
Troubleshooting the speed of USB 3.0 speed
All you need is to check for getting USB 3.0 speed, you need to get USB Device Tree Viewer application. Now you need to check the USB transfer Speed by connecting a USB 3.0 device.
Configuring USB 3.0 Device
Run USB Device Tree Viewer and choose the device from the first column. Scroll down to Connection Information V2 section on the right. Now find DevIsOpAtSsOrHigher and DevIsSsCapOrHigher. Make sure that all the values are 1 for true. One of the ports is always 2.0 for backward compatibility
Checking USB 3.0
Another way to check the device using USB Device Tree Viewer is to check the properties value. All it requires is to connect the device and choose it under USB port section in the USB Device Tree Viewer. In the properties, the value must be 0x03 for USB 3.0 Port. Follow the same steps for all the other USB 3.0 Devices.
The application also provides a visual representation of the device i.e. for a USB 3.0 the color should be blue. If it provides lower speed, there might be a problem with the USB port itself, or might be the port is loose when you experience the problems.
Checking the USB 3.0 Device
For a USB 3.0 Device, make sure that the device is actually USB 3.0, if it is not, then the speed is also slow. The USB Device Tree Viewer can help in checking the device i.e. whether it is 2.0 or 3.0.
Checking the Connectivity Cable
A broken or faulty cable may cause the speed to slow down, if the cable does not support 3.0 ports, then the speed might drop down while transferring the data. The best way is to connect the device directly to the 2.0 port.
Fixing the Problems with the USB Speed
Best way to figure out these problems is to check for the USB 3.0 driver software from the Device Manager. In case the Data Transfer Device is 3.0, make sure that the file system is the same as of the flash drive and the hard disk.
If the device or the port is not 3.0, there is nothing you can do to get the speed equivalent to 3.0.
