Solved Windows 7 usb ports not working all the time

[dragnslayr]

I have been having a problem lately where non of my usb ports will work except for the mouse and keyboard sometime. Non of my external hard drives are recognized. Went into device manager and the computer don't show hard drives. After either restarting several times or clicking scan for hard drive changes it will finally work. I have tried several different fixes people have posted to permanently fix with no success. Any help would be appreciated, thanks.

I'm not sure what the issue is with W7. But I know my Seagate FreeAgent USB 2.0 external could be left plugged in between boots on Vista x64 SP1. Not so on Windows Seven Ultimate. I don't know if it's even been fixed via update or whatever. I only have W8 on a Laptop to play with now.
