IPhone "Usb Not Recognised"

Question

Hi, I know there have been loads of similar questions since the iOS 5 and Itunes 10.6 update. I recently got a new laptop and have tried to plug my iPhone in for the first time yet a "Usb Device is not Recognised" keeps showing up. My iPhone does not show up in iTunes or on My Computer. I have tried and followed almost every trouble shooter including:
http://support.apple.com/kb/TS1538 ( Please so not give me this link, I have tried every step on it about 500 times =.=)
http://http://support.apple.com/kb/HT2292
iTune's Diagnostics (which have lead me back to the links above)
Selective Startup only having iTunes start up.
Restarting my laptop.
Making a new "Inbound Rule" through Windows Firewall for iTunes.
Checked my USB cable etc.
Getting recognised as a Camera
Uninstalled and reinstalled iTunes + everything published by Apple Inc.
Deleted everything under the Universal Serial Bus Controllers, restarted my laptop so that it reinstalled them then plugged in my iPhone.
I've stopped the Apple Mobile Device service, plugged my iPhone in, then restarted the service.  The same message pops up.
I'm pretty confident it is a problem to do with my iPhone 3G as I have tried it on multiple different computers with different Apple USB cords and it has always come up with the same message.

Answer 1

I have also found in my iTunes diagnostics log above ^^ it says that iTunes is not enabled by Windows Firewall, even though I have it enabled and followed http://support.apple.com/kb/HT2553 to enable it and the iTunes box was already checked. However, I do have 3rd party Antivirus software running (Norton Internet Security) Could this be conflicting with windows firewall? If so, how do I turn off the firewall in the Norton program so that it stops conflicting with it.
And if this is relevant, I also found that
Connection attempt to firmware update server was unsuccessful.
The network connection timed out.
Is is this important?
Thanks in advance.
