When I connect my HTC Desire HD to my computer (XP service pack 2) through USB cable, i can use the following features - 1- Charge Only 2- HTC Sync (HTC Sync version 3.0.5606, it syncs well) 3- Disk Drive (shows a disk drive in "My Computer", n also in "Device Manager", n i can browse my memory card 4- USB Tethering (I can share my phone's 3g connection to my computer) All the above features work perfectly with ease BUT, when i select, the last option, 5- Internet pass-through My computer simply "Cannot detect my Phone anymore"(it doesnt shows my phone anywhere in Device Manager), n i can hear that "disconnecting sound (tada) from XP". And after about 5 minutes, my Phone says "make sure you have latest HTC Sync n all..." (I do have a sufficiently latest HTC sync). More information - When i select Internet Pass-through, my computer is supposed to show something called as "HTC Remote NDIS based device", in my "Network Adapters".... BUT IT DOES NOT...! If someone can help me how to make my computer detect that "HTC Remote NDIS based device", i can simply install the correct drivers for it. Please help, i have wasted more than 10 hours on this thing..!
