Your USB ports on your Dell computer are plug and play. If you have issues with your USB port, it is port related, driver related or device related. The following solutions will help you identify the problem to resolve your USB port issues.
To Identify a Working USB Port
Begin troubleshooting your USB ports by checking Device Manager to see if your USB ports or hubs are working properly.
Click the Start button. ClickControl Panel.
ClickSystem and Maintenance.
Double-clickUniversal Serial Bus controllersand check to see if all your USB ports, hubs and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.
If Device Manager shows any USB ports, hubs or controllers are not functioning, check for updated drivers.
To Update the USB Port Driver
An out-of-date BIOS driver can create issues with your system recognizing the USB port.
If ALL the usb ports have stopped working, this is a problem with the USB controller. The short answer is that you cannot easily repair this. In all probability, the controller, or a circuit trace to it has blown or shorted. You would need to get another motherboard.
If one is still working, then you can get a PCIMCIA card to usb port that will give you 2-4 extra ports, but this will only work if at east one of your existing usb ports is still functioning
You need to update the BIOS of the computer. Log on to support.dell.com and look for the BIOS updates for your computer.
Once downloaded and saved on the computer run the update and leave the computer to complete the updated. It might restart a couple of times.
This should fix your issue.
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.
Since you just got the motherboard replaced you can try to update drivers, update the BIOS and the CHIPSET driver of your computer, these should fix that problem, If not then there is something wrong with your motherboard. You can download the latest BIOS and Chipset in support.dell.com
For the most part yes. Sounds like there is a short in the USB ports, causing the notebook to shut down. You can get around this by setting up a 'wireless print server' for your printer, which is about 120 bucks. if the laptop is already wireless compatable, which it should be. If Dell parts are running like they used to, they're probably quoting you about 700 for the part, and another 250+ for the labor. The print server will solve the printer issue, but other usb devices will not be usable on that machine without a new motherboard.
On the flip side, you can probably find a motherboard/cpu combo for that laptop on ebay for about 300 bucks cheaper then Dell wants for it, But unless you know how to change them out, you're still looking at about 200+ for labor depending on where you live. Don't accept a quote longer them 2.5 hours from a tech, it won't take longer then that if you don't have him reinstall your OS for ya.
Oh ya, new motherboard means windows won't boot properly, it's a piracy protection issue, and since SNs on the CPU will change, windows will have to reinstalled. most likely resulting in total loss of stored data with backup not being possibly unless you have another machine to network it to, since all external HDD and Flash Drives are USB.
you could try getting a USB to PS/2 adapter, if you have a PS/2 port on your computer. if it is a Dell made in that last 2-3 yrs ir probably doesnt have PS/2. its worth a shot tho.
PS/2 ports are usually Green and Purple. if you do have two, you might go to your local Radio Shack and see if they have any. Let me know if it works.
About the driver, there is no driver for the keyboard, except the generic USB keyboard driver in Windows.
If the keyboard is truly dead you might just go buy another one (or trie to get one from Dell, if its under warranty).
