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 uamsrrt@yahoo.com

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.

I'm trying to sync an apple ipod shuffle 4th generation to my windows xp pc. The famous USB device not recognized thing pops up. What do i need to do so i can use and sync my ipod.


Shutdown Windows.
Turn the computer off.
Unplug the AC power cord.
Reconnect the AC power cord.
Restart the PC.
This will eliminate many "intermittent" problems.

Now, connect some other USB device (mouse? keyboard? memory-stick?) into the USB port, to confirm that the USB port is working, at least for some USB device.

Now, connect the iPod to one of the USB ports.
If it is not recognized, connect the iPod to a different USB port.

This should work.

I have a mfc 465-cn and I have another computer and tried to install my printer. once I get to the part of installation where I insert the usb cord into the port and turn on the machine it doesn't...


hello

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.
if you need the manual to your Brother printer, go to this link and download or save onto your computer

Not responding, batteries good per the tester, dongle plugged in to USB port, was working fine for weeks months


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.

Have you tried a different cable? Many players happen to come with dodgy USB cords.

MY COMPUTER SAID IT DOES NOT RECOGNIZE MY USB CORD


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.

USB Ports on AL27 only work with printer and external hard drive.


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.

USB port problems with hp printer


There are few things to remember using USB.
  • If your System is in hybernation mode, don't remove any attached USB device, because it will damage your USB driver. This is one of the known problem from microsoft.
  • If you have to remove any USB device use 'Safely Remove Hardware'.

To remove currepted USB drivers its not enough to remove your printer drivers.
  1. You should un-install the 'Universal Serial Bus Controllers' from Device Manager.
  2. Then re-boot to clean registry.
  3. Install the 'Universal Serial Bus Controllers' using XP Setup CD.
  4. Then check the Mass storage, PDA etc, it should recognized by XP.
  5. Then install printer driver (don't attach printer to system untill setup finish or setup says to connect).

I think it will fix.
Please let me know your feed-back.

Thanks
Iqbal

Mouse not recognized/ mouse port not working


I kept hold about 30 seconds the blue light button on the USB controller device and it worked!. I guess that's the way to sinchronize both the mouse and the USB controller of the mouse. Ramón.
