FOR THE NEW HTC ONE :
Tested the HTC One using this USB-OTG adapter, and it does work
with USB mass storage devices, keyboards, mice, and even hubs.
I had no issues playing back media or browsing a simple USB flash
drive attached to the device. In addition an SDXC card reader I
attached over USB-OTG works, you can tweet JPEGs from your DSLR on
the HTC One via this cable! It’s nice to see decent USB-OTG support
included on the HTC One.
