Re: usb ports

Go into your Device Manager (you didn`t say which OS).
Under USB you should have something like Enhanced Host controller.
That is USB2.
If you haven`t got it, your on USB1.
Normally if you only have USB1, and you plug a USB2 capable
device in, you will be told `this device could perform faster`.

I cannot get a SanDisk flashdrive to go into either of the USB ports on my new desktop computer. I am using the USB ports located on top of the computer

To test the functionality of the usb ports in front of the computer
1. Insert another flash drive or another usb device like a usb mouse on front the computer 2. If it detect the usb device that means 2 things flash drive might be bad and the front usb port is working 3. If it does not, It means that the flash drive might be bad or the usb port is not connected to the front panel of the computer 4. Try also inserting the flash drive at the back of the computer see if the usb drive is detected in all ports 5. Check the BIOS for any usb port associativity

Windows 7 64bit with support for USB 2: when I plug my pendrive in a USB port, there's an advice saying that if I plug it into a USB 2 port, it will perform faster. But how do I know which port is USB 1...

I hate this message.
You can use a program like PC Wizard from CPUID that will tell you what all of you pc specs are.

From your specs you may not have usb 2 ports.
Device manager should also say what usb ports you have.

The best ports to use are the ports on the rear of the computer, front usb ports sometimes dont have as much power to drive external hard drives or high drain devices

Damaged USB Port

Ok I think the best method to "Fix" this would be to get your self a 4 - 5 port USB card, they are, real cheap, insert it into a spare slot, inside your PC, and install the drivers, if any, and use that one. And simply ignore the other one all together.

The emachine model KAWE0 is with operating system windows xp sp1 doesnot recognise any usb device.

Good day sir, hi, usually its one or two ports that does not recorgnise a usb device, but if all ports does not recognise the usb device, check the CMOS setup. check this out;
  • one or two ports does not recognise the usb device, this is a local fault, try to check the CMOS setup, this could also be the port itself is the faulty one having loose connection.
  • all ports does not recognise the usb device, this is a system fault, check again the CMOS setup if the USB port is enabled, check the USB device itself also. to make sure use another pc to test the usb device.
A computer virus can also cause the usb port to malfunction, run an anti virus software, if possible you can reinstall the XP and test the USB port afterward.

If all else fails, you can buy a USB card and plug it on the expansion slot on your PC.

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.

Which usb port do i plug my 3 in 1 printer in on my e machine?

It means you have a port that has 2.0 USB and your device is being placed on a 1.0 port, you would need to buy a 2.0 pci card with 2.0 USB port hookup to the motherboard and hook u the 2.0. you have an older computer that had the 2.0 USB installed on the board but not hooked up to any USB ports.

Keyboard, mouse, front USBs,DVD recorder not working

It sound like your USB Ports is the problem. Go to the Hardware manager delete the USB Ports and then shutdown and power back up.
The system then should reinstall the USB Ports and associated drivers. If not the USB Ports were probably fried by the power outage.

Location of USB Root Hub

Hi dottyo,

Generally the front USB ports on a computer are USB version 1.1, good for USB keyboard and mouse or printer.

But, almost always the USB ports on the back of the pc are USB version 2.0 which is what you are looking for. Try any ports on the back of the pc case.

Hope that helps!

My usb mouse has suddenly stopped working

Your USB ports may have become dissabled by accident
got to your system bios and see if your USB ports are enabled

If your USB ports are enabled check to see that they have an IRQ assigned to them.

if your USB ports are enabled and have an IRQ assigned to them check to see that

"Legacy USB support" is enabled.


if the mouse still does not work , you may have dammaged USB ports , or simply a defective mouse.
