I tried connecting my mobile MOTO G to my PC running Windows XP SP3. I hear a sound notifying it is connected but in the DEVICE MANAGER all i get is a Unknown Device and under that there is XT 1033 with a question mark next to it. The computer detects it when i connect it as PTP but not when connected as MTP. I don't know what the problem is. And the drivers don't get installed too.
