hI everyone in regard to otg using Usb and charging tablet at same time, I have a fusion5 tablet and a usb hub the kind with 3 usb hubs and a power in with a micro usb male plug. and a switch for otg or charge. Ive tried using a potentiometer to find the magic resistor value between pin 4 (the id ) and pin 5 ground of the micro plug.
(thought i had it at one point but not sure) as could play a avi file while charging) However now most of the timee either accesses the usb or charges, I can get it to do both , but stops charging after 8 seconds.
Anybody happen to know if a specific resistance value works for both charging and otg.
I have seen another schematic but havent tried it.
It doesn't sound like the micro usb otg cable to me. I built one without a resistor and mine works just fine. Have a look at your usb settings. Some devices require you select your choice: usb otg or charging.

Thanks How do I look at my usb settings?. I think I may not have the proper resistor setting as will currently provide power to usb and charge at same time for a few seconds then stops charging.. I turn resistance up it will charge , turn it down and will allow access to usb.. i think have to find that magic number inbetween.

Depending on which phone and version of Android you have, the most recent versions of Android have the USB settings under Developers Options.
The USB OTG charging works differently from phone to phone. Sometimes you must plug your charger cable and the USB device you want to connect to into the OTG cable prior to plugging the OTG cable into your phone. This way the phone detects charging and device.

Yes that is what I have been doing . In developer options under Usb default , no charge option there, only file transfer, USB tEThering, MID, PTP ,and o data transfer
I thanks. However i believe the default USB option is charge as thats what it is when i plug in USB to a powered cable.
. As I said jt works for A short time using USB and charging at same time with resistor between 45K and 68k
then either stops charging and continues usb or keeps charging but gives usb errrors or cant access usb but continues charging.

Update this works fine with unmodified USB hub or charge power and USB on my LG k32 phone but not on the fusion ta blet.

Hello, we all know that there are USB OTG Cables with extra power plug (Y cable) but those are supposed to power external device like HDD, DVD, or anything what consumes more power than our android device can handle.
But my question is: is there any USB OTG cable with additional power plug but for simultaneous tablet / phone charging while USB stick is used?
I want to watch something long (i.e. TV Show series) from USB stick via OTG cable but I cannot simultaneously charge my tablet, so if it take too long my tablet will be out of power before I stop watching.

That means I have to add a resistor only to usb connector or just need a different kernel, or both?
On the native firmware say that this support function is disabled. Personally, I use this CivZ-FLEX-ЛУЧ-REV3.6.2 + SphereXtreme, where works flawlessly with OTG + charging resistor 64.9 K.
I call BS!!!!
I have a stock firmware, and have been using all kinds of USB cables. Found the best are made from Sony/Ericson and Blackberry. Once you have a quality cable your charging issues will go away.
Right now I am using a 7 foot cable that is from a Sony. No charging issues and works perfectly.
Lately I found another MHL cable 2hich is called HDMI to Micro HDMI, and that micro HDMI plug looks exactly like micro USB. Will such cable work with Note 8 properly without additional power?
The version of MHL our device supports requires a power source external to the tablet. That means the adapter itself needs to provide the power (battery or power adapter) or can pull enough off the HDMI cable, which is usually not enough juice to run the connection.
MicroHDMI and MicroUSB are also not physically compatible (won't fit the same port and different pin outs) even if they look so much a like. MHL typically uses MicroUSB at one end and full sized HDMI at the other.

This is correct u need to put a 63-65 k resistor between ground and Id pin(pin 4 &5) on USB connector. Doesn't work on civatos 4.4.2 as of now. USB host works fine with regular USB host cable but no charging when u use a y cable. I use civatos 4.2.2 kernel also. Works on yyks note 2 4.3 port also..
I have test multiple times. I use a USB dac in car and need charging and USB host.
what resistor should i use on my sghi257m samsung galaxy s4 mini otg usb cable?
on my dads galaxy s5 Active it shows message that says: Do you wanna enable power sharing
is that OTG? on my S4mini nothing pops up
I know this thread is really old but i want to use a USB DAC so need at cable with a resistor as mentioned above but What ROM should I use now?? also is there anywhere I can buy a cable with resistor in it or do i have to do it myself?
Does the Note 4 support ACA (Accessory Charging Adapter) to be able to charge the phone at the same time as using a usb OTG adapter?
I want to be able to use a USB DAC and charge the phone at the same time. Is this possible?
It's a very good question. I am curious about it as well.
I have 2 pieces OTG "Y" cable. 1 of them can to charge my phone but the phone can not recognize the usb flash drive. The other can not charge the phone but the phone can recognize the usb flash drive. I need a mixed cable from this 2 )
I need a quality OTG cable, any recommendations?
Considering to use a Huawei Mediapad X2 7.0 for my 2DIN car install, since the dimensions of the tablet are nearly identical to 2DIN,
Therefore I would like to know if the device supports USB OTG Host mode and charging the battery of the mediapad simultaneously using a certain Y cable?
Thanks, much appreciated if you can give it a try!

Not sure about OTG Host cum charging combination because my understanding if you use OTG Host mode very likely you plug in a USB OTG thumb drive meaning you cannot charge at the same time.
However connecting the X2 micro USB port via standard USB cable to my laptop, I noticed I could use it as an USB device and it charges at the same time albeit not as as fast as a dedicated charging.

Yes, but not OTG.
I can confirm that, on my side, using an OTG hub with a external power plug, no way to have the device charged by external power when in OTG mode.
It is OTG or Normal charge and functions via USB.
Seems Logical because the Phone is supposed to provide the power to its USB accessories in OTG. Just my HUB has a switch that provide power to those accessories instead of the phone Itself. May-I add that switching this power button on the HUB does not function until you had unplugged & replugged the Hub in the phone after switching between the two modes. I'm afraid of the survival of the Micro USB plug of my phone, on the long run, with all those plugin, unplugin actions !!!
It's possible but with anothere Device the Nexus 7 (2012/2013) with Timurs Kernel. What's the difference of this kernel to the normal kernel, so OTG with charging is working for this device,too.
I am trying to charge my Nexus 6P while simultaneously casting a streaming video from a USB drive to a Chromecast using a USB keyboard and mouse (Basically a computer replacement scenario). I have purchased the Cynergy 3 Port Ethernet Hub USB C with USB C connector and everything works independently but I can not seem to get it to simultaneously charge and read the USB port data. When the hub is inserted into the Nexus 6P the phone asks me to choose between 5 USB scenarios (see attached picture). When I pick “Charging” the USB ports stop working and when I unplug the power supply and then plug it back in the phone defaults to “Power supply” and the phone does not charge but the USB ports work along with the items connected to them. So I wonder if simultaneous charging and data is possible with the USB C connector on the Nexus 6P? I have read elsewhere in this forum that it may not be allowed in the USB standard but can’t find any confirmation of this. Has anyone found a cable/hub that can do this or is this not possible due to the USB C connector limitation?
You might want to try something like this.

Why tell him to waste money on something that isn't going to work? The 6P doesn't support USB PD so this isn't possible.
i think you need to do some mad hacks in the kernel to get otg and charging at once (i think they did it on the oneplus 1 and possibly on the 2nd gen n7 so maybe google those for what it needs to be done?) i tried various resistors to the sense pin on the micro usb z4 which ended up not working but i have no idea how the usb c is wired up. Good luck with it anyway
I've been having trouble connecting my A8 via OTG for some time. I have a Syntec USB-C to USB adaptor, which allows me to plug usb to the phone via OTG. However, this doesn't work any more (it did originally).
Sometimes when I plug in a device, the phone flashes device connected / device disconnected, sometimes it says usb charging, sometimes it doesn't do anything. I've tested the adaptors connecting them to the thunderbolt port on my desktop, and they work perfectly.
I've also tested the adaptor by using it with a USB-C to usb-a cable to connect the phone to my computer. When the adaptor is on the phone end, it doesn't do anything, when it is on the computer end it works perfectly.
Is there something I can reset or change on my phone to get this working?? It's driving me crazy.
Thanks,
Nick

plug your phone into your computer and change the connection type to MTP
