The driver is the software that lets Windows 10 recognize external equipment and connect to it. You plug it in by connecting the camera with the USB lead.

What happens when you tried to plug-in SD card to the computer?

Have you made any recent changes to the computer prior to the issue?

To make the SDHC be recognized by the computer, we need to ensure that the card reader works in Windows 7 first. Please check if the card reader is recognized properly by the computer and you have installed the driver for it.

Meanwhile, you can plug some other storage cards to the card reader and see how it works.

I would suggest you to refer the link below

HOW did you re-install everything ?

Make sure you UNPLUG the usb cable first, then UNINSTALL the drivers and all software - reboot your computer - make sure at all times your usb cable is unplugged from the device - once cleaned and unisntalled - re-install drivers and software - BUT still, do not plug the cable - ONCE and only once the drivers are installed, then plug the USB cable, inspect the USB cable to make sure it's secured. Have you tried unplugging your printer for a few minutes and plugging it in again ?

IN windows device manager do you see the device listing with a yellow exclamation mark ?

If all else fails you may have a faulty circuit board on the printer.

Check for the location where those pictures are being downloaded. Your system/computer might be set at a default location to download all objects.

It would also work using windows explorer, go to your Camera's drive and click-drag or copy those pictures and paste it in your local drive.

You mentioned that you uninstalled the unknown device from the Device manager. If you uninstall it then connected your usb flash drive you will see an error again on your device manager. This means that the driver for your usb port is not properly installed.

To install it, visit dell website, look for the model of your machine and locate the driver, download it then install from your machine.

reinstall the USB drive with USB 2.0 drivers and will work

uninstall driver then turn off the PC then unplug the power cord from power socket, short its legs then leave it unconnected for 5min, then reconnect it to power socket and turn on PC and install driver it should work :) sounds funny but it works :)
