    Thanks, the light bulb went off last week to use that solutuion. Hopefully, this one and only port left on my laptop survives forever. I really don't want to do the motherboard option.

    Is the surge on an add-in card, or is it right on the mainboard?

You can disable this (in the device manager) but this will likely disable the USB ports on the whole machine. To add USB functionality you could install a peripheral add in card, which usually add about 4 ports for $15. This is the way I would go if it were my computer and replacement of the mainboard were not an option.

I have sahara n1356 laptop which freezes mouse and keyboard when i start it. what could be a problem


Try following tips:
Try to connect your keyboard and mouse directly to your laptop's USB ports (instead of using the USB hub) and see if they still freeze.
OR
It sounds like you're using an unpowered hub, which in my experience tends to cause most common errors with USB peripherals. It's definitely not recommended to connect any USB devices which aren't supplied with a power adapter (for instance some 2.5" external HDs and those small photo printers). These sort of devices should be connected directly to your laptop at all times.
You could also consider buying a powered hub, i.e. an USB hub which draws its power from a separate power adapter (and not your single laptop USB port).

if it doesn't work you can try this..

Click Start, and type device manager in the Start Search box.
Click Device Manager in the Programs list.
If you are prompted for an administrator password or confirmation, type your password or click Continue.
In the Device Manager dialog box, expand Universal Serial Bus controllers.
Right-click USB Root Hub and then click Properties.
In the USB Root Hub Properties dialog box, click the Power Management tab.
Remove the check from the Allow the computer to turn off this device to save power check box. Repeat steps 1 through 4 for each USB Root Hub listed in the Device Manager.

Under Power settings, check the 'USB settings' -> 'USB selective suspend settings' and make sure it is disabled.
Check Thumbnail, highlighted: Open Device manager, Double click on Universal Serial Bus controller at the bottom, Double Click USB Root Hub, Click Power Management on top right, Uncheck Allow Power...
Hope it works for you.

USB PORT FIX WIN 7


Method 1
*For Microsoft Windows Vista (and windows 7) Click Start, and type device manager in the Start Search box. Click Device Manager in the Programs list. If you are prompted for an administrator password or confirmation, type your password or click Continue. In the Device Manager dialog box, expand Universal Serial Bus controllers. Right-click USB Root Hub and then click Properties. In the USB Root Hub Properties dialog box, click the Power Management tab. Remove the check from the Allow the computer to turn off this device to save power check box. Repeat steps 1 through 4 for each USB Root Hub listed in the Device Manager.

Under Power settings, check the 'USB settings' -> 'USB selective suspend settings' and make sure it is disabled.
Check Thumbnail, highlighted: Open Device manager, Double click on Universal Serial Bus controller at the bottom, Double Click USB Root Hub, Click Power Management on top right, Uncheck Allow Power...
Method 2
*You can disable the USB Selective Suspend feature as a workaround by editing the registry. The USB device may become unresponsive because of a race condition in the Selective Suspend feature. The Selective Suspend feature suspends the USB device to efficiently maintain battery power by enabling the computer to turn off the USB device. However, sometimes this feature may not correctly wake up the USB device. Therefore, the USB device is unresponsive when you try to use it. You might want to disable this feature for server products where power management is not important or required. *To disable the Selective Suspend feature, follow these steps: Click Start and then click Run. Note If you are running Windows Vista, click Start, and then use the Start Search box. Type reedit, and then click OK. Registry Editor opens. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\USB If the DisableSelectiveSuspend registry entry is present, double-click it. If it is not present, create the entry. To create the entry, follow these steps: On the Edit menu, point to New, and then click DWORD. Type DisableSelectiveSuspend, and then press ENTER. On the Edit menu, click Modify. In the Value data field, type 1 to disable the Selective Suspend feature, and then click OK.

I have an asus m3a motherboard. all my usb ports say there enabled and working but the bottom 2 rear will not pickup any usb equipment all others do. i had a power surge warning on the bottom 2 but did not...


It actually sounds like perhaps they have gone bad. You can add USB PCI cards fairly cheap, or there is always the option of an external USB hub.

Anytime I plug something in to the USB port it give a error message that states, Power Surge on the USB port. What can I do to fix this?


The USB device could be drawing more current than the USB port can supply or the USB port may be faulty.
Get a powered USB hub and plug it into your computer's USB port and then plug the USB devices into the powered USB hub.

Nothing hooked up to usb ports but computer tells me power surge


umm, usually you can't. your board is probably feeding too much current/voltage to the usb ports or someone shoved a paperclip into the port and shorted it out (frying the power supply to the usb ports) in any case, you will probably need a new motherboard or power supply.

Power surge on hub port on my computer


Try unplugging everything from the hub and if that doesn't work then disable the hub.
You can either buy a new hub or buy a USB card. Both get the same results.

you have a serious problem. probably the board as a result of lightning or electrical surge.
unplug and open box. look carefully for small burn spots any where on board and cards.
dis connect power supply from board.
diconnect your hard drive from power supply and board.
reconnect everything and plug in and try again.
sometimes it will reset itself and start up again if nothing serious.
