Yes I have OTG support, the Tab is just picky about how much power it's willing to output. It'll power a sdcard reader or a flash drive, for instance, but won't power a Dell USB keyboard or an Arduino Uno. Sorry should have said, Samsung OEM Android 4.2.2 is the OS.
Found FTDI's official android terminal program app and talked to TELCOM with it, so once powered everything works fine. Also, a helpful app was "usb device list" it's tiny and just lists all the connected usb devices. Because Android thinks it's MacOS and won't tell you what its actually doing.
