I have the HTC One and I am trying to get it to read several sd cards/thumb drives at the same time. I have the HTC One connected via USB OTG to a powered hub. The powered hub has a thumb drive and sd card reader plugged into it. Both the thumb drive and sd card reader light up... but I can only see one device on my phone. Is there any way I can set it up so I can see all devices connected to the hub? I want to be able to transfer photos from an sd card to the thumb drive, on the go without a computer. All drives/cards are formatted to FAT32, I am not rooted and prefer not to be.
