I recently reinstalled Win XP professional on an hp laptop(nx9110) and i've been having issues with the USB ports. all the three ports are not working and the drivers are installed when you check it in device manager.
i'm trying to download sp2 for XP to see if that would fix it but meanwhile could anyone suggest what to do?

I probably think that, this is a hardware problem. The HP Compaq nx9110 Business Notebook have 1x3 USB port and comes compactable with Window XP/Professional. I would recommend to de-install the driver reboot and try to scan for new hardware and use the HP recommended driver to install the hardware back on. If that fails, like you said try window sp2 and see if that has any effect.

If all fails login to HP website and leave their technical team with your problems and hope they answer you with solutions, best of luck.

Why dont you try WINDOWS UPDATE. Did the laptop come with system drivers?

i just installed sp2 and it dint help matters at all. infact, i had to reinstall the o/s all over again cos the system dint come up at all, not even in safe mode, after installing sp2. i'm reinstalling all the drivers again now and yes, i'm using the cd's that came with the laptop.

@gentleone, tell us the outcome after your installation

ok

It would be helpful if u could tell us the name of the USB hardware.  Check your Notebook manual.  Do u also know if the USB is 2.0 or 1.1 not that it make any difference because 2.0 is back-compactable with 1.0 but very slow in read/write.

Anyway,  I will now discuss how to address an unknown device problem which is caused by a driver problem.

Try to update the unknown device driver from within Device Manager. First try letting Windows search for one. If that fails, go back and choose "Select from a list" and then "Have disk". Browse to the device CD and look for the appropriate Windows folder there. Try browsing to the Windows CD (Win9x folder or i386 folder). Lastly, try updated drivers from the manufacturer's web site.

Try uninstalling the unknown device, unplugging the device and rebooting. Replug when back in Windows.

Be certain that u have the correct drivers You may have gotten the wrong CD or a CD with drivers for more than one device on it.

Cleaning up in Safe Mode may be necessary. Unplug all USB devices. Reboot the PC. To enter Safe Mode, press the F8 key repeatedly while restarting the PC. Timing is important. Try to press quickly before the Windows logo screen appears. Pressing and holding the CTRL key may work too. Choose Safe Mode and open Device Manager. In Windows 2000 and XP, click View > Show hidden devices. Now locate all USB devices, HID (Human Interface Devices), USB drives and controllers/hubs. Remove all and save the USB Host Controllers for last. When done, restart and replug USB devices one at a time.

Just remember that you are entitled to support from the device maker. If you can't get help, do not hesitate to return the device. Some manufacturers only seem to respond to lost business. It's a shame, but it's true. Send them a message  that you won't accept shoddy goods or lackluster support.

Let me know the outcome.  Good luck

@sbucareer, thanks. the device i'm trying to use is actually an LG flash drive and yes, i'm very sure i'm using the correct driver CD because its the CD that came with the laptop. i think its usb 2.0 cos it has never complained that i'm using a low speed drive for a high speed one but i'm not sure even if its 1.1 or 2.0, the system is not detecting it.
i've tried all the things you suggested, all the devices in device manager are working properly.
the drivers for the usb root huband controller are actually installed automatically from the o/s itself(xp) because when i uninstalled the usb controllers and usb root hub in device manager and restarted the system, it came up with found new hardware and installed everything back itself.
i just finished reinstalling xp again as i said earlier and i'm still installing the drivers. i'm also trying to check if the system is still under warranty so we can just take it to xp.
i'll keep you informed.

hi guys, the usb port is still not working o after reinstalling the drivers,i finally took it to hp service centre here in lagos, i'll get the diagnosis result tomorrow. will keep you guys informed.

@sbucareer, hp says its the board o, can u imagine! everything was working well xcept usb devices! anyway thats about it sha,cheers.

@gentleone, sorry to hear that.  Anyway shaa, return it if you can and ask for refund/replacement if possible.  If you don't want to go through that just buy external USB that connects through serial port or parallel port.

You can visit xdrive they have fantastic offer on free web space.

umm.... thats true, we can actually get a parallel to usb cable instead of a new board.
i'll try it to see if it works n let u know.thanks.

Hi,

I would like someone to provide me with info regarding a my usb port. I have a H&P laptop 900, it has a USB 1.1 port. The port is recoqnised by Win 98, but when u install XP there in no icon for USB in the device manger and does not detect when i plug in USB decives into the port. Have installed XP many times and there is no improvements. Can this be that I am first copying XP on my hard disk and and then running the XP for installation from my harddisk. I have uploaded WIN service pack 1 and there was no change.

if u can any suggestions plases can you email me on davesmithclarke@yahoo.co.uk

thanx

dave

but when u install XP there in no icon for USB in the device manger and does not detect when i plug in USB decives into the port.

@david, have you installed the drivers for usb? try using the driver cd that came with the laptop and see if it works.

If the problem is on the logic board , if you have a PCMIA slot not in use, then get a PCMIA card with usb ports on it. Cheaper way of getting USB rather than buying a new motherboard.

@jogego,my boss liked HP's option better so we have a new board now and its working well.

may be you have got the wrong driver installed for the usb port if not ,may be you skipped a file while loading the windows so try reloading
