Question about Dell Dimension E521 PC Desktop

Computer won't recognize USB ports

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.

    So lame... it ended up being a bent prong on the printer usb port :\ Fortunately, it's working now that I bent AND broke it! Ugh, but I'm happy :) It's printing!

    I am going to install the above listed computer, which my brother gave me. I am not an expert by any means, and want to avoid errors in the process. He has told me that if I have problems it will probably be caused by the fancy sound card. I have no idea what to expect. My plan is to just start putting the components together (correctly, I hope!) and then plug it in. I have a new HP printer/scanner/fax PhotoSmart 7520, and wireless service through ATT. Many thanks, Gail

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.

My mouse wont work on my home PC all of a sudden

Some Computers take longer than others to recognize that there is a
mouse plugged into the computer. If it is a USB mouse try plugging it into a different port or, if a disc came with the mouse, run the disc and install it manually. If all that fails consult a experienced HP consultant. Hope this helps and please don't forget to rate.

Damaged USB Port

Ok I think the best method to "Fix" this would be to get your self a 4 - 5 port USB card, they are, real cheap, insert it into a spare slot, inside your PC, and install the drivers, if any, and use that one. And simply ignore the other one all together.

I am having a problem with my computer (e-machines T5082). I does not recognize any devices plugged into the USB ports. Printer, cameras, Zune, ect. They have power because my speakers draw power from a...

This sometimes happens because it appears that the USBs develop some type of memory and it fills up the USB register. Uninstalling/deleting the USB ports and rescanning for them may resolve this.
Unplug all USB devices except for you Keyboard/Mouse. If you have a spare or your mouse is already a round PS2 instead of USB, this is better.
First thing I would go to my Device Manager. (XP - Right-click My Computer / Properties / Hardware tab at top / Device Manager *** Vista - just click your start button and start typing 'Device Manager' and it should show in your list.) Scroll to the bottom of the list where you see 'Universal Serial Bus Controllers'. Start right-clicking and deleting each individual one. If you have a USB mouse, when you lose control of it, plug it into a different port. You can also unplug your keyboard at this point. Continue until finished.
If your mouse was USB, you will have to push your power button for a moment to restart your computer and redetect all USB ports. If it is PS2, use your mouse and click on the 'Scan for hardware changes' icon at the top of the Device Manager screen. Hopefully this works.

Keyboard, mouse, front USBs,DVD recorder not working

It sound like your USB Ports is the problem. Go to the Hardware manager delete the USB Ports and then shutdown and power back up.
The system then should reinstall the USB Ports and associated drivers. If not the USB Ports were probably fried by the power outage.

How to set up and use targus wireless computer mouse model#amw26

Under the mouse there should be a usb stick attached to the mouse which most likely should slide out from the mouse. It also appears that the plastic cover behind the two buttons (this cover has targus written on it) Should come off. After you remove the usb stick there might be a button somewhere on the bottom of the mouse that you should be able to press to get the battery cover to pop up. Then you should be able to pull up on the battery cover and remove it from the mouse. This mouse takes two AA batteries. Once the batteries are installed then plug the usb stick into any of the usb ports on the computer. The computer should recognize the drivers for this mouse (if you are using Windows 2000, XP, Vista, or Mac OS X [or higher]). If the drivers are not immediately recognized then restart your computer and the computer should then recognize the mouse. If this still does not happen then let me know. Also there is software that can be downloaded from the Targus website for the tilt wheel as it has some added capabilities that can be set using this software. The link for that software is here ------>

I hope this helps, and enjoy that mouse, it looks pretty nice!

Gateway 610 k/b & mouse unrecognized..CMOS problem??

It's not the K/M, there probably was a surge that went through, and effected the motherboard in the computer. so you can take it to your local computer shop. But, before you bring it there, back up your important files because they might have to format your HD.
