I have a OTG cable and it works with like a keyboard and mouse but I haven't had luck with flash drives. I've got root browser but still no luck.
 
It will mount your usb stick to /sdcard/usbstorage/sda1
It is kind of stupid that usb sticks wont work on a stock unrooted zmax when the hardware clearly has that capability.
Whats even dumber is that ZTE REMOVED this feature from the stock rom. There is actually a /storage/usbdrive directory but it does not do anything. SMH :eek:...
 
Yeah... Before root (just an hour ago), I tried everything I could. Even once got a directory listing... Once. Never did again.

Wondering if it was a fluke due to overflow or something...
 
Well, root with stick mount pro works great.
You don't keep getting annoying notifications? When I use the pro version it mounts /sdcard/DCIM to /sdcard/usbstorage/DCIM and gives me persistent ongoing notifications that I can't get rid of as well as annoying toast notifications on every boot. I ended up uninstalling the stick mount pro extension, then deleting /sdcard/usbstorage/DCIM(had to use TWRP file manager because Root Explorer could not delete it). Since I went back to using the free version, I have had zero problems.
 
To get a otg to work on stock unrooted rom, u can't have an sdcard in. It won't mount both at once, if rooted, stick mount works

I am able to get OTG working with a mouse+OTG cable on my Zmax (even without root), but I haven't had any success with flash drives. I obtained temp root with Kingroot, and root access was verified with Root Checker. Using USB OTG Helper, it reports that "Root access is OK!".

However, when I try to mount a flash drive, it tells me "No drives mounted (code 9)". I do see the red LED light on the flash drive light up while it's plugged into the Zmax via the OTG cable.

I don't know what I'm doing wrong or what I need to do to get OTG support for flash drives. I would appreciate any help. Thanks.
