I recently bought a 32 GB capacity USB 3.0 OTG SanDisk pen drive model number SDDD2-032G-G46.
When connected I was able to view the files in the pen drive and even copy some files, however when I copy relatively bigger files the drive gets ejected.
I tested the same pen drive with Lenovo K3 Note and the original Moto X, in both the devices it worked perfectly fine and fast.
Does this mean my mobile has a problem with handling USB 3.0 devices? Because when connecting the same drive through OTG cable this didn't happen.
