wondering if there is an adapter somewhere to allow me to plug in my Evo4g(or any mini USB phone) to an RJ45 connector...for example a console port on a switch/router and use a terminal app to configure it.
is this even possible?
thanks for any info
Wow...
Wow lol, while that's a pretty cool idea I doubt it could work... I use a USB to Serial adapter on my laptop to connect to switch gear with a Cisco cable, this one specifically,
http://www.amazon.com/Keyspan-USA-1...1?s=electronics&ie=UTF8&qid=1318030317&sr=1-1
but the phone itself would have to have a driver for it, or you'd have to custom code one yourself... Either way I'm not sure a phone would even support serial emulation over its USB connection. Cool thought though!
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.

The answer to the question is ye, you can charge and use otg. Btw, http://pogocable.com/ 20$ isn't a bad price...

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.

Ok, I'll try to explain the situation I have here:
I own a Moto Z Force with Moto Snap Projector and it's a great device to do stuff. Since I don't use it as a phone anymore, I can use it as a media player (Kodi, Netflix, Amazon...), videogames (Snapdragon 820 is awesome for emulators) and streaming console (PS4, PS3, Xbox One, Geforce Now and Steam).
What I want is use USB Ethernet and charge it at the same time. I bought an USB-C Hub, with a port for charging, but it didn't work. Since the projector is plugged on it, it has 2 USB-C ports, so I plug the charger on the projector port and it starts to charge. When I plug, for example, a thumb drive on the other USB-C, the original port for charging, the charger stops charging and it'll read the thumb drive.
The point is: I can't read the thumb drive and charge the cellphone battery at the same time. Any ideas why?! Any ideas what I must do in order to charge it and use USB LAN Ethernet at the same time on it?
Thanks a lot!
