I just formatted my system,i have drive the all the component that needed attension but i couldnt get a driver for the mass storage controller which made it impossible for me to access USB.plz i need your...

Did you put the same version of Windows on that was on before? Usually this type of driver is installed automatically. You did not say what kind of system you have, so the best advice I can give is go tothe manufacturer website and look for the driver there. Also, if you installed XP, often installing the updates will make the system recognize things it did not before - possibly the USB you refer to. The service packs are rather large files, so if you have a slow connection it will take a while. They are called sp1, sp2, and sp3. You cannot go right to sp3 because the system needs at least sp2 to install sp3. So you can install the sp2 and skip sp1, and then install sp3. I would also go to the Microsoft update website, and choose custom. That way you can select the hardware updates and maybe it will show up there.

Pci card doesint work

What you want is a USB hub.  That will allow you to connect more than two USB devices to your computer.  There are two types, USB 2.0 and USB 1.1.  USB 1.1 will work for most slow speed devices, USB 2.0 is better for cameras and hard disks that have the support.  You should confirm which version of USB your computer has, but you should be OK getting a USB 4-port hub, plugging that into your computer, then plugging your keyboard and mouse into the hub and using the other port for the new peripheral that you wish to install.  Old PCI cards are problematic because you need the correct drivers.  You also need to make sure you plug them into the proper PCI port.  It sounds like the device you got from e-bay might be bad, so you shouldn't continue to use it.  If you post the make / model of your computer we might be able to suggest a new PCI card that will work if you still want to add more ports to your computer.

Usb write protect

If you've updated your software and checked the drivers but the issue still persists, try the following things:
  • Unplug the USB device and then plug it back in. Make sure that the connection is snug and installed in the proper direction. Note that USB plugs fit one way only—if you try to plug them in upside-down, it will not insert.
If this does not solve your issue-
  • Unplug all USB devices from the computer. Then start plugging in USB devices one at a time, testing each one to make sure they all work before adding the next. Sometimes two devices will conflict and will work together.
If this does not solve your issue-
  • Is this a new device that never worked, or is it a device that you've had for a while that suddenly stopped working? If it used to work, think about what changed just before the device stopped working. Did you recently add another new device? Install a new program? Try reverting the computer to the way it was before the device stopped working. If it works again, there is an incompatibility with the device and whatever you added.
If this does not solve your issue-
  • Unplug all but suspected USB devices. Open System Devices menu-
    • Windows: Right click “My Computer” > Properties > Hardware > Device Manager > USB Serial Bus Controllers
    Under the USB information, you should see the USB devices connected to your system. (Disregard any Host controllers) The name may not be identical to your device (it may say “USB Mass storage device”), but it should have the right number of devices listed.
If this does not solve your issue-
  • If you have the device plugged into a USB hub or into your keyboard, plug it directly into one of the USB ports on the computer. If it works there, the issue is with the device to which it had been previously connected. The device may need more power than the port provides
  • Try a different computer!

Your problem is a power overload on the USB 2.0 card. If you plug in a 5volt power supply to the USB 2.0 PCM/CIA card, it will solve your problem. You can also use any USB port on your computer to plug in an A-A USB cable to power the PCM/CIA card and it should resolve the lockup. Also, check and make sure you have enough RAM memory in your comptuer for Windows XP. Recommend 512, but runs much better on 1024 (1 gig) of RAM.

Machine locks up

install the vendor specifig driver for the PCMCIA. because windows XP sp2 is also able to detect the device and when you push the device online it is detecting and there is some other device which has got same IRQ and that is conflict with this and stop. see any error that is generated in event viwer * run>type "eventvwr" and enter * see the application/system try to detect your error log and see what microsoft says about it. otherwise post the error report Thanks Arun

I have the same problem when connecting my ipod and usb hard drive. I think the card is just a piece of crap. I've also tried a different card before but had no luck either. I guess its time to get a new laptop.
