Hi All
i am new here but came on for the same reason, iphone 5 not tethering via USB to my PC.
After speaking to Apple tech support and being told by one of their "senior techs" that the iphone 5 is not designed to tether via USB only wifi or bluetooth I thought it best to look around on here to see if there are any suggestions.
The problem I had was as follows (in case anyone else has the same);
a. iphone connected to pcvia usb and pc recognised phone (itunes synced and network connections says connected).
b. personal hotspot on and identifies "1 connection"
c. IE and Chrome both unable to open pages as saying no internet connection.
Seems like there are many on here with the same issue but not fix.
I HAVE SOLVED THIS after hours and hours!
1. Go to ..... Control Panel > Network Connections
2. Right Click on Apple Mobile Local Area Connection (should say it is connected)
3. Click on Properties
4. New window comes up. Click on Advanced tab
5. Under Internet Connection Sharing header, tick the box that says "Allow other network users to connect through this computer's Internet connection.
6. Click the OK box at bottom of window.
Since doing this i have been connected to the internet and finally able to open emails etc.
I hope this helps other PC users. I should probably point out that I am by no means a computer specialist and so cannot confirm how secure this connection is so if anyone out there can advise on this and maybe of a safer way to activate the connection then please feel free to let me know.
Thanks and good luck.

PS. sorry if this is not relevant to Mac users, I'm not one but if it offers a start point to solution then great.
