I decided to order the OTG adapter for the HyperDrive Color Space UDMA2. I couldn't get it to work with direct USB connection to my D800e or D4. I also could not get it work with a CF card in my SanDisk USB 2.0 or USB 3.0 readers or with a XQD card in the Sony USB 3.0 reader that came with my D4. The only thing I had that I could read through the OTG was an old USB 16GB thumb drive. Sanho send me a second copy of the OTG. It had the same results. During my correspondence with them they sent the statement that "Our engineers have tested and verified the issue that you are having."
I have returned the OTG and Sanho has refunded my purchase price, but not the original shipping charges. I am now trying to get the shipping refunded too.
