Specifically printer and mouse. I can get the mouse to work if I take all the cords out of the computer and test each port until it moves, but the printer is not recognized at all now on the computer. It's an HP photosmart printer and will print from the camera memory card when I put it in the printer, but I can't print from the computer. I need it to work asap!! I feel that this is a USB problem and not a cord or printer problem.

Re: Computer won't recognize USB ports
If you are plugging a USB device into a different port it takes some time to recognize and install it - it re-installs for every port. There could be cable and/or port issues as well. Plug the printer into a USB port that the mouse does work on and allow several minutes for it to detect install it.

2 of youre USBs are USB 3. so you need to install the right drivers for USB 3.
Also you should check youre BIOS settings, if there is an option to enable "XHCI" support so enable it. (USB 3 needs this to work ).
have you tested all USB ports and with other applications (ie: digital camera, cell phone, USB drive stick, etc..) ?
if one USB does work, buy a USB hub and salvage this working USB port (if that is the case here, that only one USB port on your computer functions) . This will allow you to use other USB ports on the hub . But beware you will have limited useage as to what you can or cannot plug in. USB hubs generate 500mA typically for a 4 port hub, so any peripheral requiring more than 100mA-120mA current downstream may not work on this hub.

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.
It will never say it doesn't recognize a USB cord. A USB cord is just that--a piece of wire. It might tell you that it can't find the printer. Has the printer worked before? If you are installing it for the first time, did you install the software before plugging in the printer? If you have done all these things, then either the USB port is bad or the printer is. But--try uninstalling the printer first--and any software that came with it. Then reinstall the software and plug in the printer. While I did mention that the cord is just a piece of wire, it is possible that the cord has become damaged in some way. Try using a different cord. Also, try using a different USB port.
I fixed the problem by going to "Device Manager," then to the "Universal Bus". Under "Universal Bus" are a list of the individual USB ports. You have to delete each one individually. When you delete each one, a window opens up which gives you various headers; select "drivers" and hit "uninstall". When you hit "uninstall", windows will ask if you want to proceed. Select "Yes". You'll then get a "warning" that the computer may not work correctly if do this procedure. You want to proceed with the deletion of each Universal Bus port. Once you've removed the Universal Bus ports, then reboot windows. Windows will detect the individual Bus ports and find new drivers for them. Once the drivers are installed (automatically by Windows), the USB ports will be operational.
