Greetings! I tether my celly for use as a modem but it uses battery power. I want it to use the PC power thus not draining the battery thus happy celly thus happy me Any thoughts??
You talking about Wifi tether? Because what I do is I USB tether and no power issues.
If I understand you correctly and Ive not tried it but can you not connect the phone via USB and and then wifi "tether" simultaneously?
Remember the thread about IntShrUI ? Just run this file located on the windows folder while synced and done!
"I think" I now understand the issue...
I got curious and tether my Phone over USB for a few hours while downloading a big file, the phone eventually died, apparently it uses more power during tether than the PC USB can charge "500ma". The only thing that comes to mind is that you could use a double USB cable that would provide 1000ma or wait for USB 3.0 cable and hardware which provide such already by default. Or a AC to 5v powered USB cable? That's all that comes to mind, unless you can hardware hack a PC's USB port to provide more power lol

Makes sense to me since a recharge via the wall plug or my car (vs. a USB port on my PC) is much faster.
tethering
I use the assasins lament WiFi router while using the AC usb adapter. I understand exactly what your are referring to. I have tried to use the dual usb cable that comes with the Imagio, one side for connection and the other for power, didn't work to well.
One major concern is while using the USB tether mode the active sync needs to be disabled, thats a bugger when you want to download and then perform an install.

I don't know why anybody would want to do that. Experimentation for experimentation's sake, I guess. What would happen if you connected a computer/laptop via USB OTG to your Note? Would the power from the machine fry the Note? Is there even any application of this type of connection? I think not.
I have this urge to try it out, but I want to know if anybody has been brave enough to do it before
and how would you do this? where is the usb to plug into the ota device?

I thought I'd mention it. I have a USB male-to-male cable lying around. For what, you ask? I use it to connect two usb hubs together, though I can't think of any other use for it . No, it is not a USB link cable(usb male-to-male, but with some electronics in between to sort out the signals, mostly used for connecting two PCs together, AFAIK).
Nothing would happen, note won't detect the device, PC won't detect the note, nothing will get fried. Line voltage on USB is never above 5V (within tolerance) and the note expects that much while being charged as well.
I want your experience in psu schematics.This is my plan, I will buy a cheap usb hub,,I will power it with dvd player smps 5V at the same time it will supply parallel to pi micro usb socket.My question is ,Do you cut the upstream power from usb hub when you are connecting the hub? do you left it as it is,,may be a diode is present.

While I can't answer specifics on what wires to connect I would recommend taking a look at this great guide to building your own PSU for the RPi http://elinux.org/RPi_5V_PSU_construction. This includes circuit diagram layouts.

I have my Pi powered from one of the normal USB ports. The power comes from the 'power' cable of the USB hard disk that is attached to the Pi. The hard disk's main USB cable is plugged into a powered USB hub.

Do we need push more mA into her. mines running off my Tab2`s charger at the moment which is 2 Amps..??

That should be enough amps as most phone and tablet chargers will provide the 5-5.6V of power needed for the RPi to function properly.

2A will be sufficient to power a couple of peripherils including pi itself.
powered USB hub...
Hey guys, it seems ive got power issues with my pi, everything works fine if i just use the two usb ports, but as soon as i plug in my powered usb hub i get keyboard errors, bluetooth dropping, and wifi connection issues, all symptoms of low power. anyone having this issue with thier Raspi & powered usb hub?

Exactly how do you have everything plugged in?
Assuming power to pi from one source, hub to the USB port and your accessories all to the hub: See if you can get your pi to boot with the hub plugged in to the accessory port but nothing to the power micro USB.
I suspect the hub may be causing issues by backfeeding power through the accessory port. This test will tell.

You guessed correctly to how i had it all set up. I did exactly what you said, tried booting, but got nothing. i dont think its backfeeding, any other suggestions? this one leaves me scratching my head.

Are you using seperate power for usb hub ?If it is so you should cut the power terminal from usb hub to pi.See that you are supplying good current to the hub.
Does the USB port have any other function other than power?
Don't think so, only power AFAIK.
I plugged it into my computer and even tried pressing and pressing/holding the button on the Chromecast but my computer didn't indicate any hardware plugged in.
I wonder if the data pins are even wired to anything internally.
UPDATE: The USB cable that comes with it may not work for data transfer, tried it with my phone and it didn't work. So I tried a normal microUSB cable but still nothing.

It has bluetooth... so in theory that could be a simple alternative... we just need to figure out how to access hidden menus.

I tried this with a self powered USB OTG cable, just to see if the Chromecast would blink, bing, or do anything to show recognition, no dice. Also tried booting with a USB drive in, no difference.

Examining board
Based on examining the photos of the motherboard on ifixit.com...
Component EM1 appears to be a USB Common Mode Choke. That goes on the D+/D- pair which you can see routed from the USB port, so it wouldn't be present if there wasn't some use for data communication over the USB port. (Cost sensitive equipment.) The flip side of the PCBA shows TP1-TP20 (Where TP19 and TP20 appear to be GND). My guess is in that mix you have a JTAG port for programming/testing the unit initially with a pogo pin rig (evidenced by the dimples observed in each of those locations), and there might be more high/low GPIO pins where one might allow the unit to enter its USB data mode.

Looks like its already been rooted. With what looks like a dual usb otg. They don't go deep into what specific cable but, I would guess it is a generic dual usb one off ebay, or amazon, heres a quick one i pulled from amazon http://www.amazon.com/Micro-Cable-P...8&qid=1375052489&sr=8-3&keywords=Dual+Usb+otg
But if you read into it, they say you can root, but unless your a developer you probably wont get any benefit of rooting....yet, if at all.

Please correct me if Im wrong, but the cable you linked only charges the thumbdrive/keyboard/mice/etc NOT the Chromecast so how would one root it since it does need power from usb plug? I've been searching for correct cable and cant find it; link to correct cable would be greatly appreciated!!!
This cable wouldnt work, right? http://www.ebay.com/itm/Usb-type-A-..._USB_Cables_Hubs_Adapters&hash=item4857e3608e

I own that cable from Amazon and it should work. It brings in +5v from a charger connected to the female microUSB port and then splits it to the female full size USB port and the the male microUSB port so both the USB host device and the USB peripheral device are getting power.

I also bought that powered OTG cable off Amazon and it will power the Chromecast as well as provide the means to flash the Chromecast via a USB thumbdrive. When you apply power to the Chromecast, it automatically flashed the bin from the USB drive. There was no interaction required (or even possible). Of course this was on the original firmware - if your Chromecast updated itself, you have lost the ability to root the device at this time.
Clearly the Chromecast does sense the USB drive and pulls data from it during the initial boot sequence. However I'm not sure if it would ever work for other devices such as keyboards or storage devices, etc.
I'm not sure why anyone would want to hook those types of devices up to the Chromecast however. Once you have root, you can telnet into the device, so adding a keyboard doesn't seem that important. The whole idea of the device is that you send it media from other devices and control it via that other device. Adding storage for example doesn't seem important since it can pull media off the network already (ie a NAS or another computer).
Anyway. That has been my experience with it so far. It's a long winded answer to more than just your question about the OTG plug.
I would personally love the ability to send audio out without having an hdmi TV be on through the usb somehow...

USB Tethering not working - SGH-i997
Hi all,
i have install Avatar 7.0 to my Samsung SGH-i997 from "http://forum.xda-developers.com/showthread.php?t=2174227". it's look cool.
But when i am trying to USB Tethering, the massage shows as "Unfortunately,Setting has Stopped".
how to Fix this issue.
Anyone ever check the power cord to see if it's a standard USB cord with all pins enabled or just a power cord? It does have the RF choke which many don't too.
EDIT
It must be a standard USB cord because there is a caution in the setup instructions about making sure to use a standard USB port for power and not a USB Service Port.

Im pretty sure its power only, I cannot connect a phone to a computer or even charge my phone because it requires data pins to charge.
Whenever I connect my Phone to my Laptop(Matebook X Pro), it quick charges my phone. (connection via usb c to usb c)
Is there a way I can stop that from happening and my phone leeching the battery from laptop so fast? OR stop charging it all together
Because usually I only connect my phone to laptop for roms and rooting and today for Android Q. I would charge my phone before doing these things hence I don't need my phone to suck out from laptop during this. I wonder if there is a way to reduce how much power the laptop is outputting. or turn it off all together
Besides, I have a powerbank for both my laptop and phone so if I am out and about, I'd charge the phone from the battery, it's less efficient to send it from battery to laptop to phone.
You'll probably need a custom kernel with special settings for that, as they usually try to speedup the charging instead, but I recall some bugged kernel/ROM versions (for another device that was; the Nexus 6P) which prevented fast-charging when not using an official QC adapter (like connecting it to the charge USB-port of your laptop; and that kinda sounds like what you're after). Many modern laptops have special charger-ports, sometimes even with QC support, so did you try another USB-port to see if perhaps charges slower ?

You see, when I'm out and about I only carry usb c to USB c cable so I can't check other ports. Both of the USB C ports are USB PD :/

Use a cheap legacy micro usb cable plus type c adapter. Since its hard to find bad quality usb c cable. It wont pass high current to your phone. Bad quality cable usually have very thin wire..
