Hi everyone, I'm looking into getting the Mate 2 to use as a car tablet (I know its kind of small, but its what will fit in my car). What I am trying to figure out is if the Mate 2 will charge with an OTG cable, as I want to use a USB flash drive for media, and possibly a USB DAC. I've been reading that it requires an OTG cable modified with a 36kohm resistor somewhere in the cable (which I haven't figured out where) and a modified kernel, but nothing specifically for Huawei phones/tablets. Does anyone have any insight for this phone?
Thanks!

Hi together,
ive asked me if it is possible to use an adapter for 1x micro usb (plug) -> 2x micro usb (jack).
Could the phone handle 2 USB devices at the same time?
Maybe then it is possible to use the HDMI output and the USB host parallel?
For example to use an TV as screen and an HDD as the source for a movie.
This would be nice.
Thanks in advance.

When the connector is used for HDMI I doubt it can be used as USB at the same time, I'n sorry.
Maybe in a few months cyanogenmod provides a hack, if there will be an dual adapter soon.
We will see. Thank you.

The hardware needs to allow this if it'd become possible. You need a really smart USB dongle that knows how to split the HDMI output from the USB output.
Sounds a little too difficult to ever happen.
Hmm thats right. I think i still dream xD
But thank you.

it is not possible. because as stated on this forum many times before, the type of usb connection is determined by the resistor between pin 4 and 5 of the micro usb connector. the strength can tell the phone, that there is either a charger, a pc connection, car kit, jig, usb otg or mhl connection present.
and i believe, this is an important thing to keep in mind for so many things:
for instance, why the original car kit triggers car mode and generic car charging cables don't or why not just any micro usb male to usb a female will work as a otg cable or why flashing should be done with the original usb cable...
so if you were to buy or build a micro usb hub, since it has no resistor in the very plug that connects to the phone, it cannot be used for anything but charging and quite frankly, i wouldn't connect more than one charger to the phone.
however, if you want to use your phone for presentations or watching movies and still be able to use it, get a bluetooth keyboard and mouse or a bluetooth presenter or do it the other way around and use a usb input device and transfer your media using allshare. everything else is physically impossible, so neither CM nor XDA can do anything about it. the only device that can do what you want is the new motorola. it has a separate micro usb and micro hdmi port and a docking station, so you can use it as a full notebook.
Thats obvious. Thank you.

However, is there any way possible to charge your phone WHILE using the OTG adapter? They both use the 1 micro port on my phone, but I need to find a way to charge the phone while using the OTG adapter.....perhaps a micro USB splitter-type adapter?????
I was actually wondering about this myself, though I don't think a splitter-type cable would work. I'm wondering if the power connection is on separate pins than the data, though...if they don't share space then I'd think it would be possible in some fashion.

A similar problem is showing up regarding using the mhl port to output to hdmi. Though the original information indicated that the power cable was supposed to charge the phone it seems it does not on the first version (super DUMB).
I have read though that the newer version of the mhl port is 10 (I think) pins rather than the 5 of the original. The newer port DOES allow charging while output is in operation.
I suspect this will also allow an OTG cable that charges while in use.
I am not so sure about the mhl idea anymore. Only one port for everything is ok if it has enough pins/bandwidth to have a breakout box that would allow an external usb drive to be read while hdmi is being output to a screen and power is supplied to the phone. As it is now with only one-at-a-time it isn't very inspiring as the phones get closer to the power of laptops.
What would be really neat would be a box with wi-fi, and the output to hdmi and usb ports as well. A wireless breakout box. Then the charger could be over by the phone which is near the user.

I think this thread could solve your problem.
Oh... I found a useful diagram here.
Hi!
It looks like it's possible to use some USB Ethernet adapters with some Android tablets, but is it possible to have it running on AC power at the same time?
I suppose that this can be achieved with some special OTG cable, if it is possible at all. Have anyone been successful with this?
Please share what's your setup, i.e what tablet do you have, what Ethernet adapter works with it, and what kind of OTG cable are you using.
Direct links (Amazon, eBay, etc...) are very welcome for Ethernet adapters and OTG cables.
Thanks in advance!
PS: Hopefully this is the right forum to post these type of questions.
Hi, I tried with a otg cable which had an additional port for power but it's just for when u use hdds who needs more power then 450 mA to run. Android is not allowing to charge the phone during USB otg usage.
Hi all,
I have been trying to set up my S5 as my car dock/nav. like a mini headunit., but not to replace my stock H/U.
I have the otg/power Y splitter and have the usb DAC plugged in, and the audio works as expected, however i know that apparently there are certain otg cables that can allow charging the phone instead of just helping to power the otg device(s). There is also a whole setup with the nexus 7 that has been done due to a custom kernel.
I havent been following the devs as of late, but would someone know any method of making a kernel such as this? https://timur.mobi/timurs-kernel-n7-2013/
Hi guys, looking for some help here. My goal is to use a tablet with a seek thermal USB camera plugged into the charging port. It's going to be mounted in a semi-permanent location and running non stop, so I'll need to keep power to the tablet at all times. Is there a solution for this? Is there a way to plug power into the charging port while also allowing the OTG item (Seek Thermal) to work simultaneously? I've looked at some connectors on Amazon but it's very unclear if they will only Power the OTG item but not charged the tablet or both. I thought about using inductive charging for the tablet, but I'm failing to find any tablet that has an inductive coil built-in.
I'm going to purchase a new tablet for this so I'm open to whatever model works. Right now the Seek Thermal is a micro USB connection but I have a micro USB to USB-C connector just in case the new tablet uses a USB-C connection.
Thanks so much in advance!

Thanks @jwoegerbauer, do you know if there's anything pre-made available? Some of the items linked in that post are no longer available. Thx
