I am unable to help you, but I can report a thread on XDA where some ways to use OTG inoperative on Z5c then worked ... They are new attempts to do although it seems to me that your problem is not dependent on the SW, but not I know what else to suggest [USB OTG] USB Drive Doesn't Mount Sorry for my bad english (by G translate..)
