In Win Vista / Win 7

Go to Start, in Search - type in "command.exe" (without the quotes) - once it comes to manifestation - right click and run as Administrator and a pop-up will appear.

Type exactly like this without the quotes "sfc/scannow" - if this is the first time you have run this feature, it will take some time; this will repair everything in the Windows from registry to whatever and yet, you can be online or offline and do whatever you need to do while it's running in the background. (Doesn't take much resources, but I do strongly recommend that you first clear cache files, temp files, run the disc/disck clean up, etc first.)

Once it has been completed it will provide you notifications if you had any errors and the specs on this, for example - integrity errors were found and were repaired. (Just for an illustrative purpose)

I do recommend people to reboot as soon as you complete this, and above all things - keep your OS up to date always!

=========================================

If all else fails - while I am only a Windows Certified here and I cannot speak on Mac or other OS Systems - I can advise you the other option is for XP (Microsoft is disconitnuing support here), Vista, and 7 is:

Going to Control Panel to Device Manager and delete ALL USB port related hardware found on the list after you have backed up and created a System Restore first. Windows automativally will detect and reinstall - this usually resolves the issue 98% of the time.

At the last resort - is going to Microsoft "Fix-It" (clicking on Windows - select your OS - and then select hardware - install the program and allow Fix It to resolve this issue.


===================================================

< b> TO THE ORIGINA POST APPLIED ABOVE: I do want to make an admendment for I realized I forgot a sentence: It is generally a good idea to contact your OS Manufacturer, either via their website of if you have the info handy that came with your OS; then give them a call first. </ B>

<i> I hope all this helps! And good luck and do keep us posted!</ i>

USB devices pull a good bit of power. You need to check all the combination of devices in another computer. If it works on the other computer, you may wish to try installing a powered USB hub or replacing the power supply to the laptop.

You need to reboot your system for the changes to take affect.

You could do a repair.
Load the disk in the drive and reboot your machine.
Press any key to make it start with the dvd disk.
Press the install button.
Then look down to the bottom left you will see "Repair", click on this and then select the repair option.

OR:
Right-click "My-Computer", select Properties.
Click Hardware. Open device manager. Find your USB network device. Double-click it. Select the Power tab and clear the "turn this device off to conserve power" checkbox.

Hope this does the job for you.

I have a Toshiba A205 running Vista HP with four USB 2.0 ports, and this USB assignment problem happens to me on one of my ports when I reboot the laptop. However, the USB port doesn't disappear. It is assigned a different drive letter. It was originally assigned drive letter F, but after each reboot Vista reassigns it to E. This phenomenon happens when an item in one of used ports is unplugged and the laptop is rebooted while the item is unplugged.

Sometimes, its weird to see that certain Flash drives or External HDDs comes with an installation CD/DVD whatever. I wonder why this is required when those are USB devices or USB enabled. Sometimes, certain flash drives uses USB services, may be, for security purposes on the contents of ur flash drive. So,check if any and try install those. Again, not sure this would help but lets try out that.

BTW, a general question here... if the question is answered, will that be marked as answered so that the question need not to be answered by anyone else?

I know these folks and like myself; we are certified Experts to Masters - and if one looks, they are posting a negative on every single Certified Expert / Master's recommendation and suggestion?

I find this absolutely an insinuating insult; unless we have a "TROLL" in here?

TWO MORE THINGS - One you can do and another if you are not comfortable in doing the first; then try the second:

First - create a restore point before proceeding - it is easier to go to Control Panel - System - then System Protection and create a restore point faster this way than anything else, just click, click, click and go - name it whatever you want, then I suggestthat you copy and paste if all possible print it out or write it down because it isn't complex or complicated.

Go to Start - Control Panel, to your Hardware Devices; scrolling down - look for ALL of your USB PORTS - right click, a pop up box will appear:

(Do this one at a time)

On the tab panel (usually the last one in most cases but sometimes it's the first one in "advanced" - but take your time to locate it), look for the Driver Info with the options (because some are in the Normal Mode and others run in the Classic Mode is the reason why I am posting in this method). Click on Driver Update, if it asks for a disk, ignore, select Windows Update or let Windows Automatically locate it for you which would include Windows Update. If it says that the driver you have is the best driver or is the updated driver.

Go to the next one and repeat it until you have completed the list of the USB Ports.

Remain online - making sure you are connected via Direct Connect (e.g. like cable connection rather than Wi-Fi / Wireless) running on the adapter (power source) and not battery.

Now in that hardware list - delete them, and reboot; when you return back online - Windows 7 will automatically will install new hardware, you will see this icon on the lower right (standard mode unless you have tweaked it); then go to Windows Update and run a Manual Mode of Windows Update which will automatically search for updates.

Much of the time, this resolves the issue.

Sometimees Windows Diagnostics aka "Windows Trouble Shooting" will automatically appear if there were issues or problems. There is another alternate mode if you do not feel comfortable in doing this:

Go to Microsoft's website and type in FIX IT - click on Windows - Select OS Version of 7 - Option Hardware and Devices, install the program and let it run and repair the issues for you.

While it will always create a restore point; in case it didn't "fix It" - but it is handy because 99.9% of the time, it does work!
