I'm wondering if anyone knows if it's possible to have simultaneous OTG & charging with the use of a pogo pin charger?
For instance, plug in a usb OTG into the main microUSB charging port, and use a pogo pin charger [either make one or buy when they are available], and have a flash drive, or hard drive plugged in, and charge at the same time with the pogo pin connector?
I used to have a Nexus 7, and via a custom kernel, and a OTG charging cable [basically a regular OTG with additional power wires & connector for charger]. But I think it would be simpler to use the pogo pin approach. The only thing I'm worried of however, the kernel might disable OTG while it charges via pogo, or perhaps disable charging while OTG is enabled. I guess in this case, we would need a modified kernel to achieve simultaneous OTG and charging.
Here is a link to one of the first Nexus 10 pogo charger cables and it makes this claim:
"You still can power Nexus 10 while the USB port is otherwise occupied for data uses. It is fun & convenient to have MagNector to free up the USB port and charge faster."
http://www.ebay.com/itm/MagNector-N...ader_Chargers_Sync_Cables&hash=item20ce4990a6
So if that statement is true than the answer to your question is Yes.
eBay item is no longer available..
However, I know how sellers often make unfounded claims like that. So while it's probably a good sign, I am not convinced it's true. If anyone is fortunate enough to have a pogo charger, could you test it out with a otg cable and let us know the results?
Or if you're a kernel hacker, maybe take a look at the kernel source code and tell me what you think?
Also if anyone has a link where I could read about pogo pins for the N10, I'd like to read it. I'm interested in trying to make one, if they don't make any low-cost ones in the near future.

Just wondering, have you actually tried it yet? I remember on the n7 it would disable pogo charging when you plugged in otg. I hope n10 is different.
Swiped from my Nexus 10 using xda-developers app
I got the pogo cable in today. I plugged the usb-otg cable into the Nexus 10 with a thumbdrive connected to it. Stickmount recognized the thumbdrive and I can read/write to it. I noticed that the battery runs down while the otg is plugged in though. Running Paranoidandroid 2.99 with whatever kernel comes with that.

Does it say "Charging (USB)" or "Charging (AC)" in Settings > Battery?

I know it's not the original question, but it looks like that would be possible with a modified OTG USB cable. Sounds like you already have something similar.
I was thinking about this for using my n10 for larger video recording when away from wifi. Just need to hook a battery up to the OTG while its plugged into the thumb drive. It takes a charge off my laptop when connected via the otg usb, so it should work as well with the correct setup voltage/wiring .
I would also like to know the pin designation for the pogo plug. If you can do the same setup as the one above, with the pogo... There would be less chance of damage to the tablet on the go......

I know a nonstandard OTG cable [a OTG charging cable, basically the same as a regular one, except it has female USB only connected to the charging pins] and a modded kernel allowed for simultaneous OTG + charge on the Nexus 7, but I'd rather not have to deal with that, as getting a separate pogo charger seems like a better option.

It has to be a moded kernel to access the data in read/write mode? Nothing to do with charging, and correct?
What I was considering is a battery/usb hub combo. One that plugs into the micro usb port and the battery actually has a female usb port for the thumb drive (need root to write to the drive, but not to stream from it). Amazon carries lots of external batteries with micro usb connection and the female usb port.
I agree, the pogo would be much simpler and still allow data through the micro usb.
The pogo would be much better for portability for this type of use especially if it allows for faster charging. If no one has the pin layout, guess I'll wait to get mine and test them myself. 6 pins on the n10 itself so it's not a standard usb pin setup?

No, on the Nexus 7, if you plug in a OTG cable [which basically grounds a certain pin, the only difference between micro OTG and micro to full size USB adapter], it disables charging through power pins, because it needs to send power to OTG device, for example, a flash drive. It needs +5V power.
So the kernel mod was to disable the output of power, so that it could instead receive power and charge, from the charger. [The charger also 100% powering the OTG device]
Even if you have an externally powered hard drive, it needs power to turn on, even if it uses a wall adapter for the actual power to run the device.
Here is the kernel I was talking about: http://mehrvarz.github.com/usb-host-mode-power-management-nexus7/
it was made by a rootzwiki user. some discussion here: http://forum.xda-developers.com/showthread.php?t=1934722
Check the images of the USB hub on the 1st link.
Just for the heck of it I plugged a USB cable connected to my PC into the Nexus 10 while the pogo was also connected. The Nexus 10 showed up on the PC as it normally does in the file explorer and I can transfer files back and forth as usual. I went to Settings -> Battery on the Nexus 10 and it showed "Charging AC". I then unplugged the pogo cable and the status changed to "Charging USB". Plugged the pogo back in and the status switched back to "Charging AC". Then to make sure the pogo was actually doing the charging, I watched 2 hours of Netflix with the screen set to full brightness. The battery went down only 2%, so I'm pretty sure the pogo was doing the charging.

Thanks for your test. However with Nexus 10 connected to pc it is not in otg/host mode. You need to connect for example an usb memory with a otg cable to test if charging work with host mode enabled. There seems to be some discussions going on claiming pogo charging is disabled in host mode on Nexus 10 as well. It would be really really stupid if that's the case and I can't for the world figure out how they could put this limitation in the kernel.

Yes I tried that and the pogo would not charge.
EDIT: I bought a couple of OTG Y-cables on ebay (1 male micro usb end, 1 female micro usb end and a female usb end) to play around with when I saw they had a fix for the Nexus 7. I tried one on my Nexus 7 (PA rom and Timur kernel), connecting the female usb to a powered usb hub that has 16gb sdhc card plugged into it. Then connected the female micro usb end to a spare micro usb charging cable and the other end of the charging cable to the usb hub. The male micro usb end gets connected to the Nexus 7. I fired up the Nexus 7 while in the Asus pogo dock I bought for it and it charges the Nexus 7 while also allowing the OTG connection. I tried the same setup with my Nexus 10 (PA Rom, Ktoonez kernel) and pogo cable and it worked. The Nexus 10 charges through the pogo cable while the OTG works also. With the usb hub I'm using with the Nexus 10, I had to plug the charging cable into a charger wall wart. I don't think the old hub was putting out enough power to power the usb device. I let them both run over a day like this. Ran some RomToolBox app backups on both them and they both are charging on the pogo pins while doing so. If you go to system settings -> battery it shows "Charging AC" on both.
The galaxy nexus already has a custom kernel that supports OTG + charging (via a y-cable):
http://forum.xda-developers.com/showthread.php?t=1835720
In that thread (and the link in the OP there) there are discussions about porting that kernel to the nexus 7. Also, this modified kernel is (currently) for 4.1.2. Unfortunately I am not smart enough to do this myself (especially we are now dealing with the pogo cable and the USB); I do hope to let everyone -- especially the developers! -- knows about the possibility in view of the gnex kernel.
Is this an issue only with Disk Media over OTG, or is it with anything (controllers, etc.) over OTG?
If anyone is interested read my edit a couple of posts up.

It says AC charging even though it's not actually charging. Confirm this with for example battery monitor widget.

Hi all,
I've just ordered this gorgeous phone and am waiting for it to be delivered. In the meantime I've been wondering given that it's capable of HDMI output and serve as USB host whether it is possible of it doing both at the same time, if say I hooked up the HDMI output along with other usb devices, like a USB drive and a keyboard via a usb HUB. I would be practically creating a bespoke docking station of sorts..
I know it's pushing the technology a little... and there are other alternatives to USB devices (NAS drives, wireless mouse/keyboards...), but my question is more about what the device is capable of.
Thanks.
Update:
So far I've successfully managed to plug in an old USB hub via a cheap micro-usb to USB adapter bought off e-bay. From there I hooked up a USB keyboard, Mouse, pen drive and also USB speakers.
I'm amazed it actually managed to power all of these devices without any problems (imagine battery drain is massive given that the usb hub is unpowered).
I would like to know if anyone has tried hooking up HDMI output while the USB is hosting other devices. Has anyone tried this already? I've searched everywhere and can't seem to find a definitive answer to my question.
As a side note, does anyone know of a docking station for the G2, similar to what you get with laptops?
Did you figure out the answer to this?

No, I have not yet tried this out. I had bought an HDMI cable/device thing but never got it to work on my TV.. apparently it had something to do with the technology that the phone uses for HDMI not being compatible with older Samsung TVs.
Would be great if anyone else has tried this out could post here, whatever the outcome
I have a cable that works fine with my Shield tablet for this, connect a flash drive and power the tablet at the same time for instance, but not on this Lenovo.
Has this ability been disabled? and if is has, Is there a method to enable that in the software or is that hardware feature? I thought I recalled on previous stock roms on the Shield it could not do both but now it can.
Any insight is great, thanks.
It only works depending the charger... Doesn't with the included but with a 5V/3A Quick-Charge one...
your Shield has only 5200 mA compared to the 8500 mA the Yoga Book has...

I've tried a couple chargers now with no luck. The OTG cable will power the lenovo or let the USB device work, but it will not do both. I assume the one included with my Samsung S5 was a quick charge 2.0 as it was a main selling point of the phone at the time. Also I was pretty sure the Nvidia one was too? However neither of those will simultaneously charge and use a USB connected device. Again this same cable, OTG plus power, works just fine on the Nvidia tablet.
As with my Nvidia tablet I would plug in the charger, then cable from charger to OTG plus power cable, then plug into tablet. Tablet would show charging. Then connect whatever USB device I need. Tablet will show charging plus use or mount USB device.
Any ideas of what I am doing wrong? This isn't going to be something weird like the Yoga Book is wired different than every other device out there is it?

Well I am using it with a cheap 3A/5V Amazon branded charger and it works just fine...
I can only guess, but it seams your external drives consumes more than the Lenovo Book needs to be able to charge... If I am not wrong the Yoga Book needs at least 2.4A
I have a MopowerTK36W-4USB charger. It has two 1.2A 5V and two 2.4A 5V. This charger works fine with my Shield tablet to charge it while still allowing me to plug in flash drives, a 2.5 SSD, or gamepad controller. On the Yoga Book however it simply will not charge it. The idea the charger is the sore point here is driving me nuts. Shield tablet will use it's charger, the Mopower, and the Yoga's charger without issue and allow for USB devices at the same time. The Yoga Book just will not work like it.
I guess I will eliminate this OTG plus power cable as the possible culprit next and order a couple different of those cables. I can't quite grasp this generic cable working on the Shield but not on the Yoga Book either. Anyway just isn't making sense to me unless the Yoga Book, again the YB1-X90F, simply cannot charge and use USB devices at the same time? But you have stated you are able to do this so I am scratching my head here.
I've tried a couple of devices that claim to connect V20 to tv by wired usb c to HDMI connector. They work for a while then the picture is lost or the phone itself freezes up. About the longest play I've gotten successfully is an hour but usually something goes wrong within 15 minutes.*
The phone has been out over 6 months now so I thought someone may have found a really dependable HDMI connector? I don't mind the lack of power in because I can always change batteries but phone should be able to play through HDMI long enough to watch one movie. That's all I really need hut I don't want to have to screw around with it 10 times to watch one movie.
Thanks so much for your help!
I've been wanting to make use of this feature, but haven't extensively yet. I have though gotten to make fair use of a micro-USB to HDMI adapter. A few trouble spots come to mind here.
Sounds like you're powering the adapter/phone from an external power source? How good is that power source? My micro-USB to HDMI was distinctly less reliable when plugged in since I was merely powering it from a normal USB port. Try running it entirely from the phone's battery. If this works better then it could be you really need a higher power source when using the adapter.
How good is your HDMI cable? Depending on how strongly the phone/adapter drives the HDMI signal, a lower quality cable could break the camel's back.
I've been running into a different bit of trouble with USB-C to HDMI adapters. I've found several of these, but whenever they've got a USB-C pass-through, the pass-through is strictly for power and does not carry the USB signals. The MyDP specification allows for USB3 to be passed through if 1 or 2 pairs are used for the HDMI signal, but allows for USB2 to be passed through no matter how many pairs are used for the HDMI signal. There are adapters which also include USB-A port(s), yet none which include an external USB-C with the USB signals. Grr!
I use C to HDMI not micro usb. V20 doesn't use micro usb. It uses slimport. I have one adapter which allows simultaneous charging and one strictly slimport C to HDMI. Both behave the same way. I have a high quality 2.5 foot HDMI wire.
Power source was Samsung tv usb powered output 1 amp. Point is I have the same issue with pure slimport and no charging.
The one that allows simultaneous charging does in fact charge and work but always craps out but so does the slimport C to HDMI.
Hmm, entertaining what you find when you do research. I suspect the V20 is using the "MyDP" specification, which is the official specification name behind "Slimport". Seems there are at least two other video out methods for USB-C.
I haven't done enough with the video-out feature of my V20 to have much experience yet. With a V10 whenever an adapter was plugged in without external power there were no problems, but when an adapter with external power was plugged in video wasn't reliable.
I'm interested in reading if you find out anything.

Sorry I haven't tried, but its seems to connect smoother the a wifi dongle.
does anyone know if there's a compatible dongle for the V20 with not only hdmi but also power input and usb host?
Happening to me too - Any suggestions
Your situation's description fits my problem exactly. I have a USB C to HDMI that was vouched as working by several V20 owners. I plug it into my Dell monitor to play games on a bigger screen. It works well for a while, then disconnects and popup on my screen says something like, "LG Bridge has stopped working do you want to exit?". Once this happens, it's almost impossible to get the V20 to share the screen again. It's not a hub, just a USB C (male) to HDMI (female).
TLDR: I am only able to achieve a stable data connection using the Samsung usb-c cable that came with the phone. I've had my S8+ since the first day it was available in the US, Apr 21. And I've had this problem since that day.
Details:
When I plug my phone into a computer (transfer files, etc) or my car (Android Auto), it always works fine with the Samsung cable. It almost never works with any other usb-c cable I've tried, seeming to succeed only if the cable sits just right in the port. If it happens to work, and I move the phone/cable at all, it stops. On a computer, the "you plugged in a device" dialog pops up over and over again really fast (1 hertz).
I've tried it with both usb 2.0 and 3.0 ports on a couple towers and 3+ laptops
I've tried at least 3 different kinds of cables and at least 10 total cables. The cables don't sit loosely in the port or anything. They fit snug and hold fast, as I've come to appreciate about usb-c.
The other cables all work fine with other usb-c devices I have -- Pixel phone, Nexus 6p, Nexus 5x, Chromebooks, Nintendo Switch controllers
Charging works fine 90-95% of the time with other cables. When it fails, it slow charges, saying "Ensure the cable is plugged in properly" or something like that
I see articles online encouraging purchase of all kinds of non-Samsung usb-c cables to use with the S8
I would conclude the port is loose, but the cables all fit snugly, and the Samsung cable *always* works. I don't have to wiggle it in the port or anything--no effort at all.
This hasn't been a big deal for me until this week. I have usb-c cables all over the place I can charge with, and I carry the Samsung cable in my backpack for when I need a data connection. But now I have a car with Android Auto, and want to keep a valid cable in there.
Has anyone else experienced this? I searched around some, but couldn't find anything.
I'm using three different brands of type-C usb cables, micro usb cable+included adapter (micro usb to C). All are working fine.

It's a big I aqh3 I'm 99.9% positive. My MacBook pro power cable is as good as they come but it flaps like 3x then just says fail on my phone screen despite it working fine lol. It does not do this on for example the eng rom for root
I bought 3 type c cables from 3 different manufucturers. Only one of them doesnt work as advertised. Whenever i plug the phone with the cable the humidity sensor is switched on and it tells me the phone port is wet and i can not charge. Cant fidn any logical explanation but thats what i get

I experience the same problem. I haven’t tried the original cable. I just gave up on PC cable cause I never really needed it. I just wanted to use my usb c desktop connector to feel cool since usb c isn’t popular on a desktop yet. But yea constant disconnects unless you plug it without moving it, a slight wind can blow and cause it to disconnect. If the OEM cable works no problem, I’ll just buy one from a4c android store or amazon.
