Usb otg support for Android 5.1.1

[Sulleykassam1]

Im experiencing problems connecting usb drive to the xperia z3. The phone charges ok via usb. It also connects to pc via usb.
So i don't know what the problem is with usb mass storage connection!

Kindly assist

NB:
I did usb host diagnosis and found api support with question marks and also kernel had question marks.
Does this mean it has software related isssues then? Probably a bug and will go with the next update

I think they changed the USB detection in 5.0 to accommodate the Z3+/Z4 etc etc.

Because these models have waterproof USB ports, they put the USB otg setting in

/settings/device connection/USB connection/ detect USB device.

Try that, although the Z3 has a different port, they may have just put the setting there to keep things continuous between models.

Check otg cable, I have no problem on Z3 Dual D6633 and android 5.1.1 f.w. 23.4.A.1.232.

Android 5.1. 1 does not have option for detect usb connection.
Just has media transfer or mass storage ( i have tried both) and install software to pc
I tried 2 otg cables and also the same cables work on another phone ( xperia z).

That's strange I have android 5.1.1 and it detect's usb mouse, keyboard or pendrive when I connect it.

Wow...now thats strange if you have 5 1 1 and can connect and i cant.

I used android usb host diagnostic app.. And found that my android api has question marks instead of yes. Even for kernel support mine shows question mark, while its supposed to yes for support.

I dont know if its and issue with my update and that its a bug on my phone.

Which app do U use for testing? It's probably issue when updating to newer version of android, try to reflash current f.w. once againg. If this dosen't help try factory data reset.

[Sulleykassam1]

The app is usb host diagnostics

I've run this app and it says Kernel - Claims Support Yes, Device detected NO, Verdict - OS support NO, 3rd party apps NO, but my pendrive show's up as normal and I can use it. Which f.w. do You use?
