Vista will not recognize iphone

Vista will not recognize iphone, shows as a unknown device. I've tried everything under the sun that I know of to get it to work. When I first syncd my computer to my iphone 4 days ago it worked just fine. Went to put some music on it and now it doesn't.

I had both my pc and phone off. Plugged in the phone turned both the phone and pc on. It comes up that needs to install drivers for uknown device. It then comes up no drivers found, but gives me the option to click for a solution. It then brings up that I need to download the Toshiba Firmware Linkage driver. I downloaded it and began to install it, but then an error comes up saying invalid serial number. I have a TOSHIBA Satellite L305D-S5904 with vista ultimate installed.

Anyone have a solution? Any help is appreciated.

I've uninstalled itunes and reinstalled, i've made sure the driver was installed properly, i've stopped and restarted apple device manager, i've gone to the device manager and tried to install the driver to the "unknown device" manually but when i do it tells me that i have the most up to date driver but yet shows there is no driver installed. I'm lost on what to do

Have you tried doing a system restore to 4 days ago when it was
working?

Yeah, I tried that and it did the same thing.

I figured it out. The usb cord was bad.

I have a Toshiba Satellite running a Windows Vista and I noticed that if I use the USB port on the right hand side usually Windows do not recognise the plug-ins or any external device. I changed USB ports and it recognised my iPhone 4.

Thanks for bringing back a conversation from January 2009 to let us know
about your hardware issue. ;-)

I suggest getting your hardware (likely motherboard) fixed. If you think it
is software - download/install the latest motherboard chipset drivers.
