Here's another method to tether using the USB cable:

Use Data Connection from your phone to tether:
1) Put the USB Connection in Activesyn mode; tick the Enable Advance Network Functionality.
a-1) Set USB connection to activesyn with advance network enabled
a-2) Disable your auto disconnection in your data connection setting.
a) Connect the device to the PC using the USB cable.
b) Connect first to the activesyn/Windows Mobile Device Center (automatic)
c) Start ICS on the phone
d) Press connect
2) You might gett disconnected intermittenly from ICS due to the Data Connection settings. If you've set that the data connection will be automatically disconnected after X mins, basically, as long as there are no packets, it will be disconnected.
3) If you are connected via GPRS any call/sms/mms coming in will disconnect the connection
Use 3G connection and it will stay connected.
