Question about Computers & Internet
Since my iphone does not appear in iTunes when connecting it, I need to find out which one of the three USB ports in my computer is a USB 2.0 output. Please help?
On your desktop, search for an icon Computer.
1) Right Click Computer & select manage
2) Select device manager
3) On right side, you will see an Option -- Universal Serial Bus Controller
4) now connect you iphone to different USB ports & you will be able to see the one in the device manager also
5) Right click on that USB which gets selected & select Properties.
You will be able to detect it

Two solutions would be to either restore your pc to before the problem started,using system restore on accesories menu, or use the recovery cd or the recovery folder Acer laptops usually have on the 'D' drive and re-install usb controllers and drivers.

Be safe rather than sorry, get yourself a Powered USB Hub.
One of the problems with USB is that a device is only allowed to draw up to 500mA of power (100mA on first connection). So, if you buy a non-powered hub, it will only support one high-power (500mA) peripheral, and the other ports on that hub may be useless. Plug a mixture of devices into a non-powered hub and some might work while others might not. Since people expect to be able to plug any USB device into any USB port, I think this is really bad. Using a powered USB hub generally eliminates the problem.

You will have to take the machine apart somewhat, or at least to the point of being able to disconnect and remove the usb port. Here's a link to the D600 service manual download. It will guide you through the breakdown process.
