Specs: Dont Know xD, Dont know xD
hey guys..

well my problem is the following:

-Everytime I put in a USB in the USB port(s)
it doesnt work. What i get is that the pc found a new hardware and it goes to wizard updates for hardware then i just continue with what it says to instal this hardware and it says the hardware has not been succesfully installed because the software needed has not been found. Im really desperate now, ive been to the microsoft support centre and followed some instructions about why the usb port might not be working and i tried few things like deleteting the usb ports and reinstalling it. So i tried it only for one cuz i dont trust anything, and unfortunatly the usb port I uniinstalled didnt reinstall as they said because i got the same wizard which never worked.

Anyone, if u know whats going on please help me solve this xD

Thanks

Seems to me the USB ports are working perfectly but it cannot find the software needed to make the device you are plugging work. Not all USB devices are that simple, some need software supplied by the device manufacturer.

What is the device you are trying to plugs in? It would make a difference if you let us know which Operating System you are using as it makes a huge difference where USB is concerned.

You may need to plug into a different USB port, or you may have an IRQ sharing problem.

E.g. the latter was the problem with a friend's multifunction printer/scanner etc.

See response 3 in this:
http://www.computing.net/answers/wi...

Also check the port and possibly the connector on the cord, to make sure the plastic blocking plug is there and is not loose.
Or try another USB cord.

Read the installation directions.

E.g.
- there are lots of device installations that require you to NOT plug in the USB device, or the USB cable to it until AFTER you have installed all, or at least some, of the drivers and software.
- some printers, scanners, etc. will not turn on automatically when you first install them and will only be detected if they are powered on by means of a button or switch .
- if it is an external drive, most external drive enclosures require either an external power adapted be connected to them, or TWO USB connections, because a single USB connection cannot provide enough current to support the needs of the hard drive plus the enclosure's circuits

It doesn't matter what operating system you are using - the same things apply.

when u said:

"Check the current voltages in your bios
Setup."

&

"Look in System Information on the left side - Hardware Resources - IRQs "

Where can i find that?
and what does mboard mean?

Also when u said:

"Open Device Manager.
Un-install the USB root hub(s) and host controller(s)".

Well I tried once un-installing the USB root hub, only one of them without un-instillaing one of the host controller
and the result of that is that, the root hub didnt re-install as I said in my first post in the end( look up gogogo xD )
which is how I think I lost one root hub maybe?

Well reply A.S.A.P. pls ty
I come back tommorow

"It doesn't matter what operating system you are using - the same things apply."

Obviously if you're not using a Windows version, where to look for what IRQs are being shared with what would be different, and how you would re-load the USB stack would be different, but the same things you must check for apply.

Try plupging into USB ports I say are more reliable first - you may not need to check for an IRQ sharing problem.
If that doesn't help, then you probably need to cure an IRQ sharing problem, and re-load the USB stack.

In Windows, one way of getting to System Information is Start - Run - type: msinfo32, click OK or press Enter.

If Windows is not what you're using, you need to go someplace where you can find the IRQ information, or whatever the operating system calls an IRQ. If the mboard is a PC mboard, it has IRQS.
....

All USB ports directly connected to your mboard can supply up to the standard 500ma (1/2 amp) of current each, whether they are built-into-the-mboard ports already there, or port connections on pins on headers on the mboard for extra USB ports that you connect the wiring to case ports or the wiring to other added on ports to.
If you use a port in a USB hub of the type I specified, that 500ma the one port supplies is shared with all devices that plug into the hub, and that can cause problems with devices that require more current if more than one device is plugged into the hub, and in many cases a device just simply cannot work properly plugged into such a hub, even if it is the only USB device plugged into the hub.
If a printer, or scanner, or multifunction printer/scanner/etc., or a monitor, or a keyboard, etc. has a USB port or ports on it, that port or ports is/are sharing the one USB connection's 500ma current that connects the device to the computer, and many devices will not work properly when plugged into such a port.

"Check the current voltages in your bios
Setup."

When you are booting your computer from it being off, there is usually something that shows up on the screen that says "press xxx key to enter Setup" or similar - if there isn't see your system manual. If you press that key while that line is still on your screen you go to the mboard bios's Setup pages. The current voltage readings, fan speeds, and temperatures for some of your system components are in the pages somewhere, e.g., under a heading Hardware monitor or similar.
The mboard has built in sensors that detect those things.

I do not see any IRQ sharing problem that would affect USB devices in that list.
Therefore, you should not need to re-load the Windows USB stack.

The USB drivers for the USB ports are built into Windows - you do not need any special drivers.
Which USB drivers are used depends partly on Windows having the proper information provided to it - that information is provided by installing the motherboard main chipset drivers. Since the USB2 Enhanced Host Controller (for USB 2.0) shows up in that list, that indicates your main chipset drivers have been installed.

What USB connected device are you trying to install?

If it is NOT a USB mouse, USB keyboard, or a USB flash drive, you often DO NOT plug in the USB device before installing the software for it. Windows will find a device has been connected while booting or when you first get to the desktop screen, but it may not have the drivers and software for it. If you DO have the software and drivers for it, on the hard drive, or on the CD for the device, usually you DO NOT point Windows to where the drivers are - that will probly result in the device not working properly.
- there are lots of device installations that require you to NOT plug in the USB device, or the USB cable to it, until AFTER you have installed all, or at least some, of the drivers and software.
- some printers, scanners, etc. will not turn on automatically when you first install them and will only be detected if they are powered on by means of a button or switch .
- if it is an external drive, most external drive enclosures require either an external power adapter be connected to them, or TWO USB connections, because a single USB connection cannot provide enough current to support the needs of the hard drive plus the enclosure's circuits

When you DO plug in the USB device...
- Try plugging into a USB port I say is more reliable at that link I pointed to.
- If the USB connected device was plugged before into a port that might not be reliable, you may need to un-install any drivers and software for the device found in Add/Remove Programs, then unplug the USB device or the cable to it, then try installing the software again.

USB stick to store info in is what I use, like uhm... my LG USB drive.

Ive tried what u said in the end, i deleted one of the USB Ports and tried to re install it. But the computer got the message again that i dont have the software to download ths hardware something like that

Check out Driver Detective pls, because IF
(I hope u find the solution xD ) you dont know the sollution for this, I might buy it, I just wanne know ur proffesional opinion about if its a fake company or if it really works

The drivers that support recognizing a USB flash drive are built into Windows.

Your LG USB flash drive should work automatically, unless you have it plugged into a USB port it does not work properly in, or unless the data on it has been damaged, or the flash drive has been damaged.

E.g. Windows will not recognize a USB flash drive if it is plugged into the USB ports on the front of the case on one computer case that I have, but it is recognized fine when plugged into a mboard USB port.

Try the LG USB flash drive in another computer if you can, in a USB port I said is more reliable - if it doesn't work properly on that computer either, the LG USB drive is damaged.
......

If you HAVE NOT used this LG flash drive on this computer before, allow Windows to search for drivers automatically when it detects the drive, and the support for it will be installed.

If you tried that and that was not successful, or if this LG USB flash drive was working for you before......
- Try plugging into a USB port I say is more reliable at that link I pointed to.
- Try the LG USB flash drive in another computer if you can, in a USB port I said is more reliable - if it doesn't work properly on that computer either, the LG USB drive is damaged.

.......

In this case, the drivers are already built into Windows, and you probably DO NOT have a driver problem.

You can buy a program that finds drivers for you if you like, but you can find free drivers for almost anything you need in any case. The advantage of buying such a program is it may find drivers you would have to search for all over the web other wise. It may not find everything you need in any case.
....

"the hardware has not been succesfully installed because the software needed has not been found"

That is a generic message you get whenever a device is not being detected correctly. In this case, it is likely you either you have it plugged into a USB port it does not work properly in, or the drive is damaged.


......

If your problem is you can see the drive but you can't access the drive's files in My Computer or Windows Explorer...

- You are supposed to click on the Safely Remove icon (green arrow) in your taskbar lower right whenever you remove the LG USB drive while Windows is running - did you do that every time?

"I tried putting it in my brother's laptop and it worked fine, so its not the LG USB's fault"

OK, so the LG USB flash drive is not damaged.

"Btw what is this mboard USB port ur talking about?
-Also this, i dont understand what you mean by that: Try plugging into a USB port I say is more reliable at that link I pointed to.

See the info at the link I pointed to in response 2

E.g. the USB ports at the BACK of your computer in the rectangular area where most of the ports are, are the most reliable ports to try - they are directly connected to the mboard.

Also - if you have NOT connected a USB connected device to this mboard before...

look in your mboard bios Setup settings and make sure the USB controllers are enabled - there are by default, but they may have been disabled.

I looked up which mboard your model has.

Hp pavilion f1723

Motherboard Manufacturer: Asus Motherboard Name: PTGD1-LA
HP motherboard name: PufferM-UL8E

There is no info about the Asus PTGD1-LA on the Asus web sites, so it is probably an "OEM only" mboard, probably supplied only to HP/Compaq.

HP has the mboard info however.
"HP and Compaq Desktop PCs - Motherboard Specifications, PTGD1-LA (PufferM)":
http://h10025.www1.hp.com/ewfrf/wc/...
.....

Asus mboards definately have identical USB header and firewire header pin arrangements.
Your mboard has both types of headers.

If wiring for USB ports is, or has been, mistakenly connected to the firewire header, or visa versa, when a device is plugged into a mis-wired port, you can damage the mboard circuits for USB or firewire in a very short time.

You press the specified key to get into the bios Setup while booting.
You should see a line that says "Press xxx key to enter Setup" or similar in the early part of the boot, but maybe only when you boot after the computer is Shut Down - you press that key while that line is still being displayed. For HP/Compaq bioses, that's usually F2, maybe F1. (If it had an Asus bios version it's Del, but it probably has an HP bios version.)
If you don't see that line, sometimes it's obscured by the HP or Asus logo screen - try pressing F2 (or F1) repeatedly in the early part of the boot, with no CD or DVD in your drives. Or see the User manual for your HP model if F2 or F1 don't work - the key you press to get into the bios Setup is specified in the manual.

What you need to do is make sure the USB controllers are enabled - if that's okay there's probably nothing else in the bios Setup that would affect USB devices being detected in Windows itself.

BTW- I always get a few errors everytime I start my pc, one of them has to do with pchnotify.exe and the other 2 I never try to remember their name but it is a long name something like c:/ etc etc etc Ill tell you this one next time i open my pc
