    Hello,

    Two of my 3 usb ports quit working suddenly. I have 2 on the left side & 1 on the right side of my Toshiba laptop. I have searched to see if I can get this resolved.

    I found these 2 posts that seemed successful. 2 questions - as suggested in the 1st post I created a "restore" point. Opened up Notepad. I don't understand the part about "You should have 3 boxes on the bottom in NOTEPAD." Am I creating the boxes?

    I am very cautious at proceeding because I just had my hd replaced again. I was on here when I had problems trying to resolve that when I followed some instructions given to me. That is when I completely lost my h/d which it could have been something I didn't follow correctly due to misunderstanding on my part. I've been told to be very careful when doing anything with the registry which I know nothing about. And now this issue has come up.

    My 2nd ? is - do I need to do one or the other of these 2 posts? I noticed the dates these were originally posted but since these were reposted recently I will assume it's still a good solution.

    Thank you for any help. I really need my other 2 usb ports working again. :confused:

    the three boxes are when you save notepad
    a popup window appears and at the bottom of that window are the thre boxes

    1 labelled - file name
    2nd labelled - save as type
    3rd labelled - encoding

    i'll post a screen shot and edit this message

    Ok, I did exactly as this instructions I found as posted below:

    First step, Start, Programs, Accessories, System Tools, System Restore. Create a restore point and name it something like "Before USB Fix". This is to bail you out if something goes wrong during the following process and makes things worse.

    Create a file with NOTEPAD containing the following lines and save it as FIX.REG

    You should have 3 boxes on the bottom in NOTEPAD.
    1)Filename : fix.reg
    2)Save as type: all files
    3)Encoding: ANSI

    If you do not change it from txt type to All files type, then the file will actually be fixcd.reg.txt, this won't accomplish the desired result.

    -------------------------- Use text after this line --------------------------------
    REGEDIT4
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"

    -------------------------- Use text before this line --------------------------------

    Double click on FIX.REG and say yes to the Merge Into Registry question.

    Unplug ALL USB devices.
    Open Device Manager.
    View, Show Hidden Devices.
    Uninstall all devices under USB Controllers.
    Uninstall all devices under Disk Drives that you know are not present.
    Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.

    If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

    When this is done, reboot TWICE.

    Reconnect the USB devices and see if they're recognized properly.

    NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

    ***NOW, my only thing I want to clarify is this part to confirm I did it correctly.

    -------------------------- Use text after this line --------------------------------
    REGEDIT4
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"

    -------------------------- Use text before this line --------------------------------

    I saved ONLY the text between the lines in a file named fix.reg under All files & Ansi encoding.

    Double click on FIX.REG and say yes to the Merge Into Registry question. **I did not get anything that allowed me to say Yes to the Merge....

    Uninstall all devices under Disk Drives that you know are not present. **I did have under Disk Drives - Toshiba MK2565GSX ATA Device - I didn't delete it and I don't understand "you know are not present"

    With doing all that......the usb ports still don't work. Not with a mouse, flashdrive, etc. They are dead.
