USB Problems?

[vegettoxp]

Hey Guys, I have been using Vista Ultimate for a while now and I haven't had any major problems with the OS. So far I only have one problem with Vista and that is where I need your guys help. The problem is USB Ports on my system under Vista. Whenever I Plug-In my USB Thumb/Flash Drive, My PSP or my External HD into any of my USB Ports, they lose connectivety while I am copying stuff. It could be anything as of copying files.

Now whenever I Plug-In my USB Thumb/Flash Drive, My PSP or my External HD into any of my USB Ports under XP, there is no problem.

So if anyone can help me with this problem, it would really make my life more fun under Vista. This is the only problme I have so far with Vista, USB Ports. So Please help me out.

Thank You.

P.S. Fusion

That is bizzare, honestly. Have you tried it on Vista without any antivirus installed, or disabling the Windows Defender and/or Windows Search services?
