Windows 10 USBWe have earlier reported about how Windows 10 for Phones will bring much better USB support via WinHec PPT. Time to go into details and see what all is supported or not supported with Windows 10 for Phones, when it comes to USB. There seems to be a good enough range of USB drivers that are supported. For example: USB mass storage, Serial devices, Bluetooth, Audio in / out and as we already know USB Mice / Keyboard is supported too.

But there are some desired features that are not supported, like USB printing and USB video (WebCam). Check the below table. Though all these are supported in Windows 10 for Desktop. May be Microsoft can bring these two to Phones.
