When I first started my comp, the keyboard didn't work but the mouse did. I tried to reconnect but failed. So, I restarted and now both the Mouse and the Keyboard don't work. I have unplugged several times switching ports. Still failing.

First try changing the batteries, reconnect the dongle or the connection device of your wireless keyboard and mouse, then restart your computer. If the step wont work reinstall the Bluetooth/Infrared software driver the wireless keyboard and mouse then restart the computer. If this fails still look under Ad/Remove programs if you have a Setpoint installed then remove it and restart computer, both or at least one of the devices should work. If one or both wont work then you need to contact the manufacturer and have the defective device/s be replaced. Just a heads up, they may ask you to reinstall your operating system / do a reformat of your computer so you need to back up your data ahead of time using a wired keyboard and mouse. Have a nice day ahead!
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”.
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!
Try testing the mouse in another computer if available to make sure the problem is not the mouse. Also try removing the usb dongle, re-boot the computer, and then re-install the usb dongle in a different usb port then the one you removed it from. This might bring the computer back recognizing the usb mouse. You could also go into the control panel(if you are using windows) and then into the device manager. Then try removing the mouse in the device manager and then re-boot the computer and see if that works.
the only thing i can think of is your usb support in the bios settings which can be accessed by pressing del button while the comp is starting that option should be enabled if that doesnt work i think your keyboard and mouse might need replacing i can't see all usb ports being faulty it's very unlikely jim
