No USB Controller tree in XP Device Manager

In trying to get a new device recognised on a Serial port on my IBM NetVista 8318 running XP Home, I altered the serial port Bios entries from "Enabled" to "Automatic".  After re-booting I found that none of my USB ports were working (4 front, 2 rear).  All Bios entries for USB are good but USB does not now exist in the XP Deviice Manager. I have restored Bios Serial ports to "Enabled".
I have plugged and unplugged USB devices and done several reboots of the system with no effect.
How can I get XP to recognise my USB ports ?

Hi!
Windows operating systems include native support for devices and systems that comply with the Universal Serial Bus (USB) specification.
Click Start, click Run, and in the Run dialog box, type:
devmgmt.msc
Do you see the first one? You can try and get it to update its drivers. if not, all USB drivers are in the service pack 1.
let me know!

Thanks Mastersage for your response.
However, I have just found the answer to my problem posted by 'think.correctly' on Ozzu Webmaster Forum. Here is that thread text :

"no
, what i was saying, is that that entire tree, the one that shows all of the usb ports installed on the computer was not there."

"however, i solved the problem. i remembered i had a similar problem a little while ago when my dell wlan network adapter conked out. it was because something got changed in the bios. so all i had to do was "Load Optimized Deaults"
i dont know what it changed, all i know is that it worked."

"Press Del when you first turn on your computer. Find the "Load Defaults" or "Load optimized Defaults" and press Enter and it will ask you if you are sure. Press Y and then Save and Exit."

"Sometimes it isn't Del, some BIOS manufacturers use different ones. You could be able to find out as when the computer first starts up and is doing its memory test down the bottom of the screen it should say something like "Press X to enter Setup" or "Press X to enter the BIOS" "

I shall be forever grateful to 'think.correctly' for this so simple solution to a problem which has cost me a significant part of my life !

Where can I download the audio drivers? WinXP Pro SP3


Ouch XP!! It is possible, probable that the drivers cannot be obtained any more for that software. You could try and see if the computer can find any by clicking on check for updates on the relevant bit that comes up, control panel, then the Device manager, then open program and then go down to audio, click on that and then look for drivers. However I suspect that they are obsolete!

USB not recognised


Go into your device manager by clicking Start/Control Panel and from there it depends on your operating system as to where the device manager is. In Windows XP they are under System\Hardware. Once you are in the device manager look for Universal Serial Bus Controllers and if you have a + next to it, click it to expand it. See if any item has a ? on it. If so right click on it and select Update Driver.

If all are ok, then maybe you need to try a different USB Port. If all ports act that way you might be experiencing a motherboard issue with the usb controller.

Are you ever getting a message such as "Your device could work faster if you plug it into a 2.0 usb port"? If so, that might be contributing to the problem. Fortunately for you on a desktop you can put in a fast 2.0 usb port card into one of the pci slots on the back of the computer. So, all is not lost.

I dont have 2.0 usb how can i update my present usb controller


Dear Friend,
You can identify whether your PC has Hi-Speed USB or not relatively
easy. Open Device Manager and expand the Universal Serial Bus section. There should be an "Enhanced" USB host controller present.
d16424f.jpg
There are currently 7 manufacturers of the Hi-Speed USB host silicon themselves:ALi (Acer Labs), Intel, NEC, Sis, VIA, NVIDIA (shows as "Standard" controller),Philips.
Note:Older computers may have only the slower USB 1.1 interface. Adding USB 2.0 isn't difficult, but it does require a hardware addition.

There is no need to Update your USB in Latest PC.
You have to do one thing is that ensure you are perfectly Installed your Drivers(Included in CD which you Owned when Purchasing PC).



I hope You made it clear ...Thanks for Contacting FixYa...

USB ports not working


Method 1: Use Device Manager to scan for hardware changes loadTOCNode(2, 'resolution'); Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.

  1. Click Start, and then click Run.

    Note If you are running Windows Vista, click Start, and then use the Start Search box.
  2. Type devmgmt.msc, and then click OK. Device Manager opens.
  3. In Device Manager, click your computer so that it is highlighted.
  4. Click Action, and then click Scan for hardware changes.
  5. Check the USB device to see whether it is working.
If scanning for hardware changes fixed the problem, you are finished. If this method did not fix the problem, go to Method 2.
Method 2: Restart the computer loadTOCNode(2, 'resolution'); If scanning for new hardware did not fix the problem, try restarting the computer. After the computer has restarted, check the USB device to see whether it is working.

If restarting the computer fixed the problem, you are finished. If this method did not fix the problem, go to Method 3.
Method 3: Disable and re-enable the USB controller loadTOCNode(2, 'resolution'); Use Device Manager to disable and re-enable all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition. The USB controllers represent the USB ports in Device Manager.

    Note If you are running Windows Vista, click Start, and then use the Start Search box.
  2. Type devmgmt.msc, and then click OK. Device Manager opens.

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.
