Unspecified USB Pen Drive

Hi,

This can be caused by a driver issue or virus-infected USB drive. For further isolation of the issue and for us to provide a solution suitable to your pen drive concern, we need additional information. Can you answer the questions below?

• When did this happen?
• Were there any recent changes made to your device prior to the issue?
• Does it appear in the disk management?
• Can you connect other USB drives and see if the same error will occur?

In the meantime, try updating the USB driver as an initial troubleshooting step and see if the error will occur again when you connect your USB drive. Follow the steps below:

• Open Device Manager.
• Look for Universal Serial Bus controllers and click it to expand.
• Select the driver then right-click on it and select Properties.
• Under Driver tab, click the Update Driver
  button to update the driver.

We're looking forward to your response.

 

related to pen drive

Hi,

A Pen Drive or USB is a data storage device that includes flash memory with an Integrated USB interface, and is a Plug and play device. That said, your computer should easily recognize your Pen Drive without any issues. A software might be blocking it, or
an update is needed for it to work properly. However, let us isolate your concern by providing the answers to these questions:

• Is your Pen Drive working in other devices?
• Were there any changes (Updates, software installation) made prior to the issues?
• Have you tried using another Pen Drive on your computer?

in the meantime, we suggest that you insert your Pen Drive, and check if there's any error(s) in Device Manager.

We're looking forward to your response.

 

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.
