SOURCE: Compaq Presario v2000 w/ dead USB ports

I have the same problem with my Compaq Presario V2000. Lost both USB ports and HP tells me that the motherboard has to be replaced at $300 +..I searched and found a PCMCIA card with two USB ports for $10. No problems with the USB ports on this card..great and cheap solution.
My belief is that the compaq usb ports do not have power limiting circuitry therefore allowing you to overload the output power on the ports. My ports failed after I downloaded into a burglar alarm system I was programming.

Usb ports not recognizing pen drive, external drive, ipods or iphones but 2 out of 3 usb ports will charge the ipod and iphone. please help!! I've tried unplugging, removing battery, device manager says...


Generally USB ports are part of the motherboard so you will not be able to replace just the USB ports. you can try to uninstall the USB controllers in device manager then reboot your computer. they should automatically get reinstalled. also try booting to safemode and check if it will recognize your USB devices.

*if you get a pop up for found new hardware when you plug in any of your USB devices then it would usually indicate that the hardware is working fine and the problem is with your OS

I have no idea what is wrong with my scanner. My computer won't even acknowledge it's existence anymore. But the printer function on my HP 2355 works fine.


1. Verify electricity
2. Verify connected to computer still. (USB assumed)
Unplug it and plug it back in at both ends of the wire. Make sure USB is not in a network port.
3. Pull electric from printer 3 min. Restart computer.
4. Test; if no joy reinstall printer, but do not plug in USB until asked for it.

Ctrl keys dont work, bought new key board and have same problem, have windows XP


First rule out drivers
- remove the keyboard driver and instruct windows to reinstall the driver

Next check for hardware issues
1. Plug this keyboard into another PC to see if the same problem persists
2. If the problem does occur it is the keyboard (get a new one if that is the case)
3. If the problem does occur then it is not the keyboard it is the port that u are plugging it into.

IS IT USB?
4. If it is a USB Keyboard, plug it into another USB port
5. If the problem persists on all USB ports on the system board, then the problem is the USB ports only IFF the keyboard works fine on another system in other USB ports

Is it PS/2?
If it is not a USB keyboard and it is a PS/2 board, again, and it works fine on another PC, then you have a defective PS/2 port on the system board.

Solution
Get a PCI card with USB ports and install it. Plug ur keyboard into that.

Icon won't appear on desktop.


It is possible that your USB flash drive is dead.
The other solution is to try it on some other USB port of your PC (if you used front panel USB ports now try it on the back panel).
If it also wont work, try to connect it to some other PC
If it works with an other PC, your USB ports are dead
You can try going to device manager, and to unintall USBs and reinstalling them

I have 3 usb ports( two at the back and one on the


Check to see if something else will work on the side port. It may not necessarily be a dead port. Just something you should know too; I used to work for Wal-Mart in the electronics department and they had to recall all their firefly flash drives because they had a tendancy to malfunction. Try using it on a different computer, it might just be a dead flash drive. I hope this helps your problem and I hope your flash drive didn't have anything too important on it :x

Usb ports not recongized


Hello,

Do use in the front ports, sometime this port is unplug to the motherboard so it need to connect before you can use that port. In the back port you can always use that ports in there it is safe to connect any plug and play device such as flash disk or usb port printer. if this both not recognize your any device you inserted then probably your device is dead. try insert your device to other pc to see if still working if not then maybe the driver of your pc are not installed. try reinstall all the driver of your system.

may this help.
