Serial/Usb Connectivity

I really wanted to convert the wifi to USB conductivity on my EZB4 to connect directly to my pc, but after reading the tutorial the USB converter uses the camera port. Did I miss were you can still use the ARC camera with the USB conversion. Thanks, merne

Bing Speech Recognition Control Moves To Desktop 2 And Cant Be Moved

My Bing speech recognition control sometimes moves to the second desktop and I can not move it from there.

I believe it happened with the last update but not sure.
