No but if for instance you install usb wifi on one usb and then plug ur usb wifi into another usb port sys will detect new device and install software for it.

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.
  1. Click the Start button. ClickControl Panel.
  2. ClickSystem and Maintenance.
  3. ClickDevice Manager.
  4. 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.
  5. 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An out-of-date BIOS driver can create issues with your system recognizing the USB port.
  • Watch a Video on Steps to Update Bios on Your Computer.
    1. When the update process is complete, your computer will restart again to load the operating system with the new driver version installed.

To Run a Diagnostic Test on your USB Port

Dell has an online diagnostic tool to help identify and fix issues with your system.
  1. Go to theDell PC Diagnosticpage
  2. UnderChoose a Diagnostic Type, selectHardware.
  3. Using the scroll bar on the right-hand side of the window below, locate the listing for USB.
  4. SelectUSB.
  5. ClickRun Diagnostics.
  6. Agreeto Terms and Conditions in Legal Statement.
  7. Follow the instructions to test each USB port.

My dell latitude d600 usb ports stopped working how can i get it fixed. thans


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

I have a toshiba laptop and broke my usb port by removing my printer usb. The computer worked fine until I restarted it,now I can only get a blck screen. It turns on buit it seems different. what can I do?


The USB interface is rugged and is designed to only allow a connector insertion one way. However, if a connector is upside-down and forcefully jammed into the port at an angle, it is possible shove it in and in doing so breaking the port's hardware. If you examine the port closely, you may see the part with four contacts bent such that the contacts are shorting to the metal shell of the port. Inserting a small piece of cardboard between the contacts and the shell may be sufficient to remove the short and so allow start up to proceed past the power up check of the USB ports. If this doesn't work, you can try pressing F8 repeatedly on power up to get into Windows safe mode menu where you can select different modes of start up including one without any drivers which may allow you to bypass the USB hardware problem. But this is a makeshift solution which only gives you very limited functionality. If the laptop is still under warranty, take it in for repair by a qualified technician. If the cardboard trick works and you don't care if one USB port is no longer functionable, then you can as an alternative just leave things as they are.

The USB Ports on my ACER TravelMate 2350 Series Laptop, I have deleted the USB Port files from Device Manager and the machine reinstalled them when I re-started but it didn't change anything. I downloaded...


Hello,

I'm guessing your USB ports don't work or does it always ask you to install them. If you have your Windows XP license key at hand, please try downloading and installing the following...

Acer TravelMate 2350 XP Chipset Driver

Reboot. It might ask you to do a reactivation, or not.
Please recheck if your USB ports still work. If not, restart your machine, hit F8 continously until you get many options - choose the option "Safe mode" and press Enter. Check if it picks up USB in this Safe mode.

What you can also try, is that you have 3 different USB 2.0 ports on your machine. Try each one separately and see if one of them works. I would also recommend to see if the USB device you are trying to use is actually functional.

Did you install any Anti virus . Check the USB port for any physical damage. Try connecting a mouse with USB port to check if its working. After all this then the issue remain the same then the USB port needs an replacement.

USB ports work at 1.1; s/b 2.0


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.

Thinkpad T20 won't recognize usb port


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.
