After reading 27 pages of posts in this thread, I can't believe I am the only sad soul who received an OTG adapter from EPO that seems to be DOA. I have tried a variety of thumb drives, SD card adapters, hubs, and other USB devices, and no joy. I thought that my solder job might have been faulty, but that means I should still be able to use usb-otg-plugin to activate host mode, right? I tried that, and nothing.

Any suggestions (other than sending it back)?
