My USB ports have all of a sudden stopped working properly. When i plug my ipod nano in, my laptop acknowledges that it is plugged in and my ipod begins charging, but itunes will not recognize it and it does not show up in "my computer." When looking in the "device manager" it says that everything is working properly. Also, when i plug my cruzer usb stick into my laptop, the same thing happens. My laptop acknowledges that a device is plugged in but it does not show up in "my computer." The strange thing is, when i print something from my laptop using the USB connection, it prints fine.

I know that it isn't a problem with my ipod or USB stick because they work fine on all of the other computers in my house. I have also gone through all of the apple support tutorials of reinstalling the usb drivers and trying all 4 usb ports but nothing has worked so far. If it helps, i have a 3 year old toshiba satellite A105

Everything was working fine up untill about 2 weeks ago. If someone can help me out, I would greatly appreciate it!!

Hi there:

try the following fix:

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.
