I was digging into the search an could find nothing about it.
I had my excalibur working properly and after a hard reset, I was unable to reactivate this function.
I'm telling about use USB cable to share PC internet connection to HTC. I mean, navigate over the internet (with HTC) using USB cable conection instead of WIFI or GPRS alike.
When I sync my mobile, it automatically disables the WIFI connection, but I can't navigate just through USB connection.
