Usb device not recognize


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.

USB Drive


Make sure you are matching the compatibility of USB 1.1 and USB 2.0 between the devices (computer and USB devices).

USB 1.1 device will work in USB 1.1 and USB 2.0, but USB 2.0 devices will not work in USB 1.1 plug in the computer.

How many USB ports do you have in the computer? Which ones have you tried other pen drives in? List the USB ratings for each device and port in the computer to further help.

Have the other USB devices been formatted with other computers? The formatting on other systems might not be compatible.
