Interesting. I actually tried this with S4 and Galaxy S w/ CM11 and S4 told me that I can transfer photos, Galaxy S /w CM11 automatically mounted itself in MSC mode. Just like you would connect it to the PC.
That's actually interesting. Which tablet is it with what rom/kernel? I could try to modify OTG interface on the Z1 or disable data transfer on the device that's meant to be charged, so you could switch between charging/data transfer. I thought that's not possible to charge a phone with another.
