Hello. When you plug in a USB device you must also download and run a disk called a driver. If you do not have a disk, you can download one. Just go to the company web site for the product and find the free downloadable driver. For example if you have a lexpro product, just google lexpro.com/drivers. Joe

please rate my answer as very helpful. thank you.

How to fix ?USB device not recognized? error in windows


Are you getting a “USB device not recognized” error whenever you plug in a USB mouse, keyboard, or other USB device? I love USB and have 5 ports on my computer so that I can connect my mouse, keyboard, camera, phone, and printer to it all at once!
However, last weekend, my computer stopped recognizing my USB devices! The strange thing about it was that the USB ports were not bad because all of my devices were still getting power to them. I could still charge my cell phone without a problem!

So I started with the normal fixing methods, including uninstalling the drivers for my devices and reinstalling them. That didn’t work! Next I tried System Restore thinking that maybe I had installed something and it caused a conflict with the USB system drivers. That didn’t work!
I read online that in order to fix this problem I should go to Device Manager and uninstall all of the devices under USB Controllers. Restarted the computer, reinstalled the USB drivers, but the problem STILL did not go away!
You may also see in Device Manager that the device shows up as an “Unknown Device”. 42b721d.png
So how did I finally fix the problem? Well, apparently it’s a super simple solution! No need to edit the registry, uninstall drivers, or anything of that sort.
Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Yes that’s it! Note that this does not mean just turning off your computer because modern computers don’t really turn off when you press the power button as the motherboard still gets power.
First to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be “rebooted” also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!
So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in.
Hope this helps someone fix that pesky “USB device not recognized” Windows error!

You need to find out what's wrong before you can fix it, so:

These instructions are for WinXP (WinVista or Win7 will vary).

Login to the system as an "administrator"
START > Control Panel > System > Hardware (tab) > Device Manager (button) >
1. click VIEW (drop down menu)
2. select "Show Hidden Devices"
3. select each USB device one by one, checking each for any entries under "Conflicting Devices,"
under the "Resources" (tab). If a device has no resources tab, then just check "Device Status"
to see that Windows thinks that "This device is working properly."

What you're checking for here is resource conflicts (DMA I/O addresses). In the case of a conflict,
you'd get "device not available or being used by another application."

when your keyboard and touchpad are not working, try to connect an usb mouse and keyboard to the laptop, just to be sure the system is responding.
if the usb devices work, you can be pretty sure there is an hardware problem. if the usb devices don't work too, maybe the system got stuck, and the best thing to do is a system reset

Usb ports


Go into your Device Manager (you didn`t say which OS).
Under USB you should have something like Enhanced Host controller.
That is USB2.
If you haven`t got it, your on USB1.
Normally if you only have USB1, and you plug a USB2 capable
device in, you will be told `this device could perform faster`.
