I have an HTC One. As you might already know, the stock (with Sense) ROM doesn't work because HTC have a USB Host whitelist that prevents the camera from being seen. There are custom kernels that remove this whitelist and DSLR Controller works fine with those. But to address your actual question, yes I've fully converted my phone over to the Google Edition 4.3 ROM and that also works without a hitch so I'm not sure why yours doesn't. Are you certain you have good cables? Do other USB devices work? Have you tried the USB Host Diagnostics app?
