I have been researching into this. The M10 tablets have paired Pogo pins which are for charging only so they charge through a dock or the speaker doc. There looks like no signal transfer for a keyboard and/or mouse. It will also switch off that port if you plug in a USB cable to the device, likewise OTG hasn't worked for me when on the dock!.
I now have a laptop style USB bluetooth keyboard and trackpad to test out with this.
