Unhappy My USB ports aren't working...PLEASE HELP!
Ok so here's the deal I have a Powerspec V305,



and its not the greatest computer ever, but it works pretty decently w/o too much error. Three days ago I installed Registry Mechanic and now my USB ports in front don't work, the ones in the rear, do work. but the ones in front where I very often attach my Iphone and camera no longer work at all it seems. I used the restore option on the registry mechanic...no luck...I did a complete system restore no luck. Any ideas?

Try the device manager. See if any errors are logged against any usb entries. If there are, then try reinstalling the usb drivers, there should be an option with the device propities somewhere.

Try this registry fix for missing usb ports by JohnWill

Johnwill's solution

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