    Installing VCP Driver crashed my USB Ports??

    Hey everyone!

    I know quite a bit off topic, but I'm a bit stuck and I was hoping the community could help me out a bit so that I don't spend yet another hour trying to figure out what the h#ll is going on...

    I'll start from the beginning:

    I'm trying to get this USB to Serial Port converter working and detected by XP:

    http://www.trossenrobotics.com/store...er-MM232R.aspx

    I tried to plug in this converter and Windows didn't recognize a new devices as being plugged in, so I figured I needed a driver.


    I checked out this site:

    http://www.ftdichip.com/Drivers/VCP.htm

    and downloaded this (under Windows XP - Driver Version 2.04.06):

    http://www.ftdichip.com/Drivers/CDM/CDM%202.04.06%20WHQL%20Certified.zip

    After extracting it, I realized I had no idea what to do with it, so out of desperation, I downloaded the setup executable (under the comments section):

    http://www.ftdichip.com/Drivers/CDM/CDM%202.04.06.exe

    After I ran this, two command prompt boxes came up with some text (couldn't catch everything they said). After that, my USB Wireless mouse stopped working. After a little troubleshooting, I realized that none of my USB ports are working any more. I went to the add/remove programs and didn't see anything with FTDI in the name. I even did a System Restore and that didn't work

    For those that don't know, I'm not very experienced in the hardware side of things, so there may be something VERY basic that I'm missing here...


    EDIT: I probably should state the error that I keep getting: "USB Device Not Recognized"

    Under system properties is there something that is flagged as not working?

    Device Manager? Nope, the only thing that is showing a ?, is a PCI communications controller, which I've had for a few weeks now (just too busy to try and fix it )

    To start with, I would uninstall the drivers you just installed completely. Make sure you have a PS/2 keyboard/mouse plugged in and go through and start reinstalling drivers on your usb roots.

    that's just it, I cannot find how to uninstall the VCP driver that I just installed. I don't see anything in add/remove programs nor did I see anything with FTDI or VCP in any item in Device Manager Is there an area that I can unistall drivers that I am missing?

    I found this:

    and under:
    Your Problem:
    If you get "Usb device not recognized" in Windows and the above solution doesn't work for you, there might be other causes:
    A) USB device worked before but suddenly stopped working:
    It talks about deleting all oem*.inf files and removing entries from the registry. A bit over my head and messing around in the registry always freaks me out a bit. Could someone with some experience look at this page and tell me whether or not I should try this?

    Let's go least destructive/dangerous first.

    Click Start -> Run, then type cmd, and press [Enter]
    In the command prompt - type sfc /scannow and press [Enter].
    Make sure you have your XP disk handy in case it wants it.

    If that doesn't turn up the culprit:

    Go into the device manager and click on view menu, and then show hidden devices option
    Uninstall all the USB devices listed
    Shutdown and turn off the computer
    Unplug all your USB devices
    Power on
    Let windows boot, then start->shutdown Then power back on. Repeat this step twice
    Reconnect your USB devices one at a time with Windows running after the two additional cold boots we did above.


    If this doesn't work, we'll get more nitty gritty
