Hi, I would like to add an context menu handler for a Bluetooth Low Energy devices in win7. I started from the sdk sample "DeviceFolderExtensibility". Which Device Interface Class should be used in HKEY_CLASS_ROOT\DeviceDisplayObject for Bluetooth devices? Or should I use any HardwareId instead? I tried BTHENUN, BTHPORT GUIDs, but don't work (my context menu does not show up). Same handler works well for HID class guid. -Gary
