Windows 10: USB 3.0 Flash Drive not detected in USB 3.0 port

my USB 3.0 flash drive is detected when plugged into the 2.0 USB port, but not when its plugged into the 3.0 USB port. But my 2.0 USB devices are detected when plugged into the 3.0 USB port.

Is there any way to make it so 3.0 USB detects 3.0 USB?

:)

 

USB 3.0 transfer speed drops to 0 only on one port. USB port and external drive are NOT defective.

I have a Dell XPS 13 laptop with two USB 3.0 ports. I connect a Seagate expansion drive to the left USB port and transfer a 4GB test file. It transfers about 1GB at 150MB/s and then transfer speed drops to 0. Then it picks up again after 3-4minutes, then
drops again intermittently.

I connect the same Seagate drive to the right USB port. The same 4GB file transfers with a constant speed of approximately 150MB/s. Thus the Seagate drive is not defective. Perhaps the left USB port is defective.

I connect a Sandisk 128GB flash drive to the left USB port (that is now suspected defective). It transfers the same 4GB file with constant 130MB/s speed, no speed drops!

Each step is reproducible 10x.

I am out of my wits here.

 

USB device over current status detected.

Thanks for the reply and the information. All the USB ports look normal. I have plugged flash drives into each port and the plug in seems normal also. The case is a full tower case by Cooler Master HAF and this case has three USB 2.0 ports on the front
of the case and also two 3.0 USB ports. There are also 2.0 and 3.0 USB ports on the back of the case that are for the ASUS X99 mother board. When I disconnect everything from all USB ports on the case and the motherboard, the error from American Megatrends
says there are 0 USB for keyboard, 0 USB for the mouse, 0 USB for drives, but it says it detects USB- " 3 Hubs". I don't have anything connected to any of the USB ports so I don't know what it means when it says it detects "3 Hubs". I was using the three 2.0
USB ports yesterday to transfer video from this computer to a newer computer, and I used several flash drives to do the transfers. I completed the transfers without a problem. Could I have damaged the USB ports plugging in the flash drives? How can I tell
if one of the USB ports has damaged connections? Thanks.
