I have read all of this thread with great interest. I have rooted the inkbook with kingroot and I have ADB enabled and working with the device.

Did you check it with a powered USB OTG cable or via powered USB HUB? All those devices need a powersource to have working USB OTG.

Before I do any firmware update I'd like to be able to save the current build on the device. if someone could tell me the adb commands to do that or an alternative method I'd be much obliged. Secondly, to update the device, do you believe it is possible to just use the update.zip file for the T62D firmware from feb 2016 that andyisb used above to get his usb keyboard via power otg working? I read in this thread there is a sequence to use to get the update to apply, namely hold power and refresh buttons, then after 5s let go of the power button. On the inkbook obsidian I don't believe I have a refresh button so not sure what that may be on this device.

For this, you should read more about it. I firmly recommend reading all of this thread
