Long story short, USB OTG does work on the D4 stock rom, updated and bone stock
Thanks. i actually was fooling around with my touchpad last night and found out it needs external power as well. so with a y-cable from a seagate portable harddrive, i was able to test that the OTG cable i have is indeed working. however, i could not get my D4 to work using extra power from my PC, but I picked up a kodak power brick today and its charging, so here's hoping that works.
actually nevermind, after playing around with a hub and a usb stick, it decided to work with my PC supplying extra power. after that, DSLR controller worked as long as there was extra power supplied. i imagine the battery pack i picked up should work quite nicely. now to go take HDR photos of the entire world! bwhahaha
