Dell e6440 usb 3.0 port not working

Does the usb3 socket recognize usb1 or 2 equipment?
I have usb3 but is will not run at 3 speed without the usb3 cable and usb3 device. The cable has a, what looks like, a squashed HDMI plug.
There should be usb3 hub loaded in your device manager.
Download the drivers from dell and see if that fixes it. All drivers are free of charge.

Computer won't recognize external usb hard drive

try it on another computer if that dosent work you should
reformat your computer but first backup all your data by putting your another internal hardrive on your computer and move all your files you need to the empty hardrive and after that take the hardrive with all your stuff in it off the computer and then reformat the hardrive which the external hardrive does not work on and install a new operating system then put the other hardrive with all your stuff back on your computer and transfer your stuff into the hardrive with a operating system then try the external hardrive

you can burn all your stuff into a CD or a DVD
you can put all your stuff into FlashDrives and then after you reformat the hardrive with an operating system put your stuff back into the computer and after that the external hardrive should work

Connect the external disk-drive to another computer.
If it still is not recognized, then you have a problem:
* the USB-to-disk-drive interface inside the case is faulty,
* the disk-drive inside the case is faulty.

If the former, disassemble the casing, and extract the disk-drive,
and temporarily connect it as an "internal" and "slave" disk-drive to your desktop, and see if you can read the files.
