Both of my USB ports quit working... I have a Dell Inspiron 5160 Windows XP... I got an power surge on my USB port message, and every time I hit reset, the message kept popping up. So, I went to system restore, and chose a day last week when it everything was working fine... Now, there is no message, but neither USB port is working. Is there a way to turn them on? Without them, I can't print anything... or transfer my needed files to my keydrive, etc.... Thanks for any info.
