I tried my experiment using the ColorSpace USB port. I connected 2 USB cables together with a USB female A - female A adapter. The ColorSpace would not recognize either the D4 or the XQD card reader.
I did an online chat with Hyperdrive support. A Hyperdrive USB OTG adapter is needed to make the connection. It will allow connecting either to the XQD reader or the D4. Unfortunately the USB OTG adapter is $50 + $10 UPS in addition the the ColorSpace UDMA2.
