Re: USB ports not working
I am hoping that your USb FLASH Drive is a plug and play like a pen drive
so what you can do is
right click on my computer->properties->hardware->device manager
the device manager window will open and then you should go to the bottom of the page here you will find a list of USB controllers
what i would recommend is to uninstall all the usb root hubs
and any other device you see listed there like usb mass storage etc
also uninstall the controllers if you wish
then reboot your computer.
this would solve your problem .
if it does not then there might be a problem with your windows
i myself had the same problem with windows sp2
so i upgraded my system to sp3
and reformatted my comp
but try the previous one first
if that solves the problem then you are all ready to go.

If USB devices such as jump drives, digital cameras, or printers are no longer functioning properly when connected to your laptop, the USB ports may have malfunctioned. There are plenty of troubleshooting steps you can complete on your own to get the port up and running properly again.
1.Connect the USB device into a different USB port on the laptop or another computer to make sure the problem isn't with the device instead of the port. Check to see if the device has a "Write-Only" tab. Push that tab into the unlocked position if it still isn't working in a different port. 2.Click "Start" and then "My Computer" if the device works in another computer but not on your laptop. Plug a device into the port and wait to see if the USB port shows up in the list of drives. Click on "Map Network Drive" if the drive does not appear. Choose a drive letter from the drop down menu and then double click the location of the USB device. Click "OK" and try to use the port again. 3.Navigate back to the Start menu and then click "Control Panel." Double click on "Device Manager." Scroll down the list of options and click the "+" located to the left of the entry labeled "Universal Serial Bus Controllers." Double click the name of the USB port that appears in the new menu. Click the "Drivers" tab and then click "Update Drivers." Wait for the driver to finish downloading and attempt to use the port again. 4.Close the drivers tab and right click the name of the USB port. Click on "Properties." Click the "Power Management" tab and then un-check the check box labeled as "Allow the computer to turn off this device to save power." Choose the "Communications Port" tab and then scroll down to the box labeled "Resources." Click the "Enable Device" button and then click "OK." Attempt to use the USB port again. 5.Close the Properties tab and right click the name of the USB port. Click on "Uninstall." Restart the laptop and then plug a device into the USB port. Wait for a new window to pop up and follow the on-screen instructions to re-install the USB port software. 6.Restart the computer and press the "F1" button on the laptop's keyboard once the manufacturer's name appears on the screen. Scroll down through the list of options that appear and highlight the option labeled as "Advanced." Press "Enter" and then scroll down and press "Enter" on the "USB Support" option. Press "F10" to save the settings and finish loading the operating system. 7.Open your web browser if your laptop is running the Windows XP operating system. Navigate to the Microsoft website and download the Windows XP USB 2.0 driver (see link in Resources). Restart the computer and try to use the USB port again.
Try this fix, turn off your computer properly then unplug the computer from the wall socket, then press the power button and hold for about 3-5 seconds. Then plug your computer back in, restart the computer then wait for the boot to settle into Windows.
After doing those things plug in a USB device into the same port as you have been doing. It should work now, if it does not plug it into another port if it does not go to all of the ports and try them all if none of them work then you cable may have come loose on your board or it is a bad USB HUB on your computer it is obvious it is not the unit if it worked on another computer.
You will have to replace it or if it works on one of them then change out the bad one. Replace it! Or go and get a 4 port USB extension using just one of the USB ports. So that you will have more ports without the fix. Replace any worn parts or devices that do not work anymore. John
This happens when anything draws over 500mA, of current, if it was working OK, before, and is working now but displays that message, or not working, well in any case it seems to have gone faulty, and somehow, is now drawing more current drain, the USB port can supply. It may have been spiked too.from all the plug/unplug especially if the safely remove hardware is not used.
1st prob. - I appears there is a loose connection problem somewhere - try reseating your RAN and hard disk.
Try to determine which part of the laptop is causing the problem, not moving the laptop around the room but by flexing different parts of the laptop and power cable etc. while it is on your table.
2nd prob -
Some USB devices draw more power than the USB port can provide and you get the error message - "exceeded power limit".
In these cases you will need to purchase a powered USB hub, connect this hub to the laptops USB port and connect the offending USB device into the powered USB hub.
hi there , hey have you went to the bios setup and checked the setting for the usb port and made sure that they were inabled and checked device manager and looked for view and than selected devices by connection and seen if there were any problems and you can also use the system restore if all fails and see what that gets you ok please let me know there still is a lot of things that can be tried but see if any of these will help
best regards mike
does your usb mem stick have any light indicators? if yes , whenever you put you usb stick, does it light? if it lights are USB ports is still ok, You just have to reformat or partition you USB stick.
(you can also try other devices like usb mouse or any usb devices that lights up when you connect it)
if there are no lights if you plug, or no indication that a power goes to your stick, its possible that your usb your are busted. if this is the case, if your laptop has a PCMIA slot, you can find a pcmia USB card, if you dont have. your only option is replace the motherboard.
Your computer is functioning correctly.
The USB ports on your laptop are USB1 ports its pard of the hardware.
Your PCMCIA USB 2 card runs at USB 2 speed and therefore when you connect a USB 2 device to this port you will not get this USB message.
You can get a PCMCIA adapter with 4 USB v.2.0 slots on eBay. It requires power from the USB port on the laptop, but the pigtail connector is included. Works like a charm! Comes from China just like everything else in this country.
I think you might have a loose cononection for the data ports. Try putting a little bit of force on the usb device. Up, down left right. NOT ALOT. If it starts working when force is used, i tihnk you should try to take it apart and resolder the connections. If it dosen't work, uninstalling the driver and installing.
