At this stage, I can't offer any suggestions except using a compact USB microSD reader like the Kingston Mobilelite Plus or Sandisk MobileMate (USB 3 version).
My system treated the microSD card a little differently between the internal card reader and a USB card reader: in the USB card reader the file manager offered the "eject" function and just had a single reference to the card, whereas in the internal reader it showed a reference to each of the top level directories and I could only right-clink on one of them and select "unmount" after which the multiple directory references seemed to hang around until the card was ejected. Apart from the fact that I find microSD cards and the 100s-11IBY internal reader very fiddly to use (I have largish hands), I found the more standard "eject" treatment of the external USB reader more intuitive.
