I have developed two apps which communicates between android phone and google glass over USB cable. So that I have written two apps, one is USB Host app and another is USB accessory app. These two apps work fine for mobile to mobile communication and i have written an application for google glass as an accessory. But Mobile and Google glass could not connect. It shows me

04-26 12:18:55.041 529-742/? E/UsbDeviceManagerJNI: could not open /dev/usb_accessory
If anyone can tell me, why do arise this error? it will worth for me.
