hi,
I could sync with BT devices on tpad airii until i installed (not sure which worked, sorry) http://techtablets.com/download/teclast/x98_air_3g/windows_drivers_and_utilities_/Air%203G%20Updated%20WLAN%20and%20BT%20drivers%20Nov%202014.zip

now my kaiser baas kb 10006 can connect but(and maybe this is meant) my logitech k400r works if i plug the logitech little receiver thing into a micro male to std usb female cable.
I am so glad the current slew of new tabs./2in1s/whatever they are are coming with more ports.
On that note, after readiing a suggestion from Chris I searched 802.11ac on ebay.
Dual band wifi (2.4mhz & 5mhz) std size usb receiver/sender nodules can be bought & delivered for $15au! – I am of course assuming they have decent range etc. They appear to do the full gamut of current and draft 802.11 wifi standards, which means a whole range of cheaper 2in1 are good to use in schools across australia (which predominently only have 5mhz wifi, so parents had to buy more expensive t100 etc).
cheers
Adrian
