Pcmcia Usb 2.0 Cardbus Install Problem

I have purchased a 02 Micro 0z6912 cardbus controller with 4 -2.0 USB ports. When installing inserting this card into my HP P-4 laptop, Win XP SP2 immediately recognizes the card and installs it. The problem is there is no reaction to any ext. devices that are plugged into any of the 4 ports. I have tried to use the Installation disk but Hardware Wizard says the device as installed and it finds no better drivers on the install disk. I have tried to install USB 2.0 drivers from the install disk general menu but the device still does not respond to ext. hardware being plugged into it. The install procedure in the manual suggests that the Hardware Wizard will ask for drivers after the hardware is installed but that is not the case. HELP!!

 

Hi,
First thing I would do is go to the laptop manufacturer's website and find the driver downloads. There could possibly be one for the PCMCIA controller or it may be part of the chipset drivers (Intel calls them INF Updates).

You can safely uninstall the PCMCIA controller in Device Manager, it will be automatically reinstalled when you reboot. This may automatically reinstall the drivers for the card (voila ) but you may need to uninstall the card's drivers and try again (look for different avenues in the New Hardware wizard and check there are not similar models available and the wrong one was installed).

[Check for any listing that may have been put into Add or Remove Programs (Control Panel) for the card.]

Driver problems are usually a matter of uninstalling and reinstalling, otherwise look at drivers higher up, like the PCMCIA controller and Universal Serial Bus controllers. Check in Device Manager for any problems listed. It may not have installed the "Enhanced" controller for the card that runs the "high speed ".

Let us know how those go, we could try finding the manufacturer's website and looking for troubleshooting information.

PCMCIA card clean up- how do you rid of it OR make it work??

Thanks for your suggestions but this thing is a nightmare- you can not even get rid of the device or drivers in Device Manager! If you uninstall, it comes back on the next boot up. System Restore doesn't work either. I image it has left it's install info in other files as well. In Device Manager, there may be leftovers in 'System Devices' as well as 'USB Controllers'. I don't know which items to delete or uninstall. They may just pop back up on boot up as well. There has to be a way to 'clean up' the system. Do you know if installation problems are typical of any PCMCIA card that comes with USB 2.0 ports? Thanks for any additional help!

 

Let's check that we are talking about the same items in Device Manager.

I expect the USB card will appear under the heading Universal Serial Bus Controllers, but controller/s and ports (Root Hubs) that are built into the motherboard should be there as well. You should see a difference when the card is in the PCMCIA slot compared to when it is not in the slot. For the USB card to work correctly as USB 2.0, there will need to be a heading "..... USB...Enhanced host controller ".

Just a thought, most USB 2.0 will not install unless you have Windows XP SP2. You are running SP2?

If you see/find the listing PCMCIA Controller, it can be safely uninstalled, but as I said, you should check for updated drivers.

Windows Plug and Play can install the wrong drivers and that may be why it keeps coming back, but they may still be the wrong ones. When you do Update Drivers and the New Hardware wizard runs, try going to "I will select the drivers from a list ". Sometimes there will be a few "Compatible" drivers to select from, or you can look through manufacturer's model listings. Also use the "Have Disk..." button and direct it to the drivers on the CD. Does the instructions say the name/model of the USB Controller, those will be the drivers you are looking for.

Can you try the card on another laptop? I might be thinking the worst and you don't say why you need the card (the laptop only has USB 1.1?). USB devices all draw different amount of power, but still they add up. You could be putting a strain on the (USB) power system which is not exceptionally powerful in a laptop. The power system is also running the card itself and any other devices connected to the system. Consider getting a self-powered USB hub if this may be happening.

USB 2.0 cardbus upgrade problem

I have injected my response in red next to your questions and replies- thanks so much for taking the time to followup!!

 

02Micro 0z6912 USB 2.0 Buscard problem

Perhaps this unit, made in China, comes with inadequate user driver CD/ instructions for accessing the correct drivers- may be outmoded model as well- wonder if there is any access to tech support for this product? I believe the correct USB 2.0 drivers are embedded on the driver disc but there is no SETUP exe files to support the installation properly. Hardware Wizard doesn't bring up any choices when searching different folders on the Driver CD that comes with this device. Has anybody tried to upgrade a P-4 laptop from USB 1.1 to USB 2.0 by purchasing a PCMCIA Buscard that contains 4 USB 2.0 ports?? Has installation been sucessful? My system says this device is installed properly but nothing I plug into it shows up in Explorer- seems to be dead- no response! The CD manual shows pics of 'NEC PCI to USB Open Host Controller' being installed into the USB Controllers section of the device manager but none of this happens. FRUSTRATING after many hours of trying to bridge the problem!!

 

What I think you should try is to go into the BIOS/Startup configuration settings. There should be a menu like "Integrated Peripherals ". Find the onboard USB and set it to disabled. You can always go back and re-enable it, but it would probably be best to take it out of the equation until the 2.0 card is installed correctly It will free up resources that can be allocated to new card.
ALSO, if I find problems with drivers, I rarely hestitate to boot into Safe Mode and uninstall the drivers in Device Manager there, because the drivers in question are not running at the time.

Windows keeps installing what it thinks are the correct drivers and obviously, they aren't. It has wrongly identified the hardware.
Options I would take:
[Disable the onboard USB]
If you can find what appears to be the correct set of drivers on the CD (and you may need to find both the drivers for the "cardbus" and the USB Controllers), look through the files and find those files with the .inf extension. Right-click on them and select Install.

Have you tried "Allow Windows to search for updated drivers online ". I usually only use this as a last resort.

Low priced hardware has not gone through Windows/MS driver testing. If Windows refuses to identify the hardware correctly, you may need to look at getting hardware that is MS certified

A little more information.

Looking at the "list" of drivers on my computer when I go to "update driver" (Hardware Update Wizard) for the USB controllers, in the list of compatible drivers [EDIT: unchecking the box "Show Compatible Hardware" will show all possible hardware], there are standard drivers to choose from. Setting standard drivers may allow Windows to identify the hardware correctly.

Any search for NEC USB drivers just goes back to Windows Updates. If the drivers are not listed by going to Windows Update, you may be sunk. rolleyes: Not very helpful if you are trying to use USB to connect to the internet).
