[Q] What would happen if you connected a computer via USB OTG? - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

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.

usb power tether

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.

You need a USB Host to go cable - they are pretty cheap off of ebay.
USB hard drives don't always work - at minimum you will need a powered hub.

i know wht USB on the means but how do i enable it. i have tried connecting with a pendrive with the help of the USb on the cable but it does not show .
Once you plug your on the cable in the phone will inform you that usb connecter s connected. Whatever you plug in at the other end of otg cable work run unless it is not supported.

Just plug it in and look in My files. It will show as usbstorage.
I have an official samsung OTG cable, it works fine on the SGS2, but doesn't appear on the Galaxy Note under usbstorage.
Anyone else out there having similar problems?
i had grab some ebay OtG but after unmount and remove the OTG it causes wakelock which drain alot of juice.
I am also facing problems with OTG . when i plug in the cable thr is not msg nor anything happens in phone. please could any one tell me how to enable it may be with kernel or custom rom or may be anything else.
I also want to know this as well,I have spent considerable time yesterday trying to make this work but no luck at all,I would appreciate if someone could help,as I have seen a video in this forum where the guy was able to.connect a mouse to it stating that it is supported out of the box.
I was able to get it to work with a pendrive and a mouse with no problems, but I couldn't get a keyboard or my 2.5" external drive to mount.
Details:
My OTG cable was from DealExtreme for $2.30 or something.
My pendrive was FAT32 formatted.
My mouse was a basic $10 optical one.
My 2.5" external was NTFS, which probably goes some way to explaining why it didn't work even when I gave it some extra power from my desktop PC too.
My keyboard was a standard USB. I also tried a Logitech keyboard with a wireless USB dongle but that didn't work either.
I watched a whole film off my pendrive with no issues. I messed around with the mouse a bit, but the cursor moved too slowly for my taste and the scroll wheel didn't scroll webpages, which is half the reason I'd plug a mouse in anyway.

If you get no message when the cable is plugged in on it's own, chances are it is a problem with the cable. I bought a cable of Ebay which didn't work, so I bought a different one and that did.

[Q] USB Tethering between TAB (P7300) and Smartphone (I9003)??

I have a Galaxy GT-I9003 phone and a GT-P7300 tablet.
Both devices support tethering to a PC via USB but, according to customer care at Samsung NZ, it is not possible to tether the phone to the tablet (or vice versa) with USB, only via wireless or Bluetooth.
I find this a bit strange.
Any thoughts??
I looked around for a cable to connect the two devices so that I could test this, but it looks like Samsung does not supply such a cable.
It may be possible to rig a cable using the cables supplied with the devices and a USB adapter??
doesn't it strike you that your phone has to be in USB host mode while your tablet as USB client?
That alone may be a feat to achieve, cabling comes later.

Always thought USB was a 2-way street.
Never considered the host/client scenario.
for example, your PC USB ports are host ports. You can connect devices to it and the OS will see the device and use it.
The port in your phone/tablet is usually a client. You only plug it so that the PC can see it.
Having said that, Galaxy Tab 10" has a USB host port function, and you can plug a mass storage to it, a mouse, or a keyboard, I think.
Some of the cheap tablets even allow you to plug a USB 3G dongle modem to it.
Now, whether your GT-I9003 has host port function, I don't know.

OTG w/ charging

like most MHL cables that include the charging port (where you just plug in from wall), is there anything like this for OTG??
tried finding and searching but nothing.....
If you're looking for power going to the USB device, then you can use this.
If you want to charge your Note while using the OTG feature, then I've not yet come across anything like that.
Just wondering if it is possible to charge the Note 2 while using the OTG yet? I'm in my car all the time and use an external SD card. My 64gig internal card is already full.

How about a scenario where I have External Battery charger and OTG adapter with usb stick. I want to watch the movie on usb stick while also have External battery connected charging the phone. I guess it's the same problem as not being able to charge up phone from any external source while using another device connected to OTG?

You could make your own micro USB OTG cable. I still haven't seen one for sale anywhere.

Oh, I don't have issues with OTG cables. I have adapter and cables, and modified cables before: http://forum.xda-developers.com/showthread.php?t=2107985
I just want to figure out how I can watch movie from usb-stick while charging my phone at the same time. There seems to be no solution for that yet? Or are you suggesting there is a way to make a custom cable to do that? I think once you attach OTG cable to connect a peripheral device, you turn Note 2 into host and it will not accept charging from micro-usb port. No way around it

Oh, I understand what you mean now. In that case, you are correct. You cannot charge your phone and use an external thumb drive at the same time through the usb port. When you plug in an external drive, your phone switches the USB power cables to send the juice instead of receive it.
The only ways I know around that are to use a wireless charge stand or the desk dock.

Yep. Not possible with just a cable. It needs a microprocessor to regulate the current in and out. Devices plugged into the dock are powered by the dock's power, not the phone's.

I hear what your saying, but looking at threads in the S3 section like this one: http://forum.xda-developers.com/showthread.php?t=1953061 got me thinking... I'm just trying to make an audio cable for my car that charges and has 3.5mm out to my radio. And I need it to work with every 4.1.X kernel and above, especially stock.

If you get a pinout for the s3, might be able to modify a cable to do both.

USB Port

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.

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...
