I have a moto x and I am plugging it into my computers, each one fails to recognize it as a media device, the settings in the storage section of the settings application are set to MTP. I've did it on a Linux machine with mtpfs install and looked at the syslog. The machine isn't even trying to recognize the device. The usb cable is working since I am getting a charge from it but it doesn't seem to be registering itself to the machine as a media device. Is there a setting that I need to set here, is something broken, It can't be my computer since I tried it on many computers and none of them worked. I have been having similar problems with my Nexus 7 tablet. Did google introduce something, or is this a bug.
