Hi,
I'm experimenting with USB OTG through hub in P3100, with CM11. My active usb hub has a LED that shows whether it is powered from USB host, or from DC adapter. Now my tablet works in two different ways:
1. Tablet is Off -> I connect USB hub without external DC -> Tablet On -> Hub LED shows that it is powered by tablet, it can work without DC adapter
2. Tablet restart -> I connect USB hub without external DC -> Hub LED shows that it is not powered by tablet, I can power it by DC adapter to make it work
Can someone tell me is it normal behaviour, and if so, is there any way to switch between these modes?

I am trying to connect my NVidia Sheild to a powered usb hub with no luck at this point.
Heres what I'm using:
Powered Hub
USB to Ethernet
OTG to USB
Male to Male USB
So I am taking the OTG to USB and connecting it to the Sheild OTG port. From there I have a Male to Male USB connecting the OTG to USB to the Powered usb hub. When I do this I can see that the Sheild's power light is orange which indicates to me that it is getting power and not acting as the USB Host for the Hub?
I did notice when I tried to use an air mouse directly with the OTG to USB it works as it should but not when it's connected to the powered usb hub instead, then nothing works (just charging). Also my ethernet adapter doesnt work via the powered usb hub or the OTG to USB.
BTW this whole physical setup worked just fine (plug and play) with both android MK808 and MK908. I was surprised that the Sheild isnt picking this up as well.
Can anyone tell me if I have incompatable hardware and if so what is compatable? Also I do not have ROOT access to the Sheild...yet, could that be the issue?
Many thanks in advance.

hello, I have tested using mousepad, logitech unify wireless keyboard mouse, usb drives, they all work well with my asus zenfone
zenfone > $2 usb-otg cable > usb hub
usb powerbank > usb hub to give the devices power
so with the power from the usb powerbank, the devices get power and android recognises them.
good, but, is there a way to use the phone as usb host, but charge it at the same time ? maybe, a "usbotg" - Y dual cable ?
Theoretical question:
While in console mode, is it possible to have the following accessories attached at once?
1. Mini hdmi out
2. Usb hub
3. Ethernet
4. External hard drive
5. External power (obviously running through usb hub) or charger
6. Bluetooth controller
Thanks in advance
I have not tried it myself, but it should work, as long as the hard drive works with it at all.
I got:
HDMI
USB mouse
USB keyboard
USB pendrive
via OTG attached at once. Haven't tried USB power and Ethernet cable yet.

Hi,
I'm trying to use an android device with a USB C connector on a local wired network while still keeping it powered.
In the past I've achieved this just fine on an older device with a microUSB port and a microUSB Hub that had power + OTG USB to which I attached an USB to Ethernet Connector.
Currently I've tried using an Anker Premium USB-C Hub with Ethernet and Power Delivery.
A few months ago this hub would only power the device, but Ethernet/USB would not work.
With the latest updates (Android 7.1.1) either Ethernet works, but the device doesn't charge(if I connect the hub first, then power the hub)
or the device charges but Ethernet doesn't work (if I power the hub first, then connect Ethernet).
With the micro-USB Connector I've also spotted a pinout diagram that shows to provide power + OTG here:
http://electronics.stackexchange.com/questions/34741/can-an-android-tablet-serve-as-usb-host-and-be-charged-simultaneously-through-a
But I couldn't find an USB C equivalent pinout.
Any hints/tips on how I could both power and USB C connected Android device and keep it connected on an Ethernet Network ?
Thank you,
George
