Just a followup on this...
I bought the correct resistor and some micro-usb connectors and made a rig per the spec but it doesn't work on my tablets. Admittedly I am using cheap no-name tablets. I suspect that this feature is simply not implemented on these tablets although I have no way of knowing if it is a deficiency in hardware or software. It's entirely possible that this would work on a name brand tablet and if I get hold of one I will test it to see.
In the meantime I have come up with a workaround that should get me by. I used a small, powered usb hub that has a micro-usb connector for charging at one end and replaced the ends to create a charger/hub/otg cable. Basically, I connect a power supply and my footswitch to this hub then I can use one end to charge and the other end acts as an OTG cable. I just have to remember to swap which end is plugged into my tablet depending on how I want it to function.
It's not what I had in mind but it'll do until something better comes along.
