HOST USB or USB HDMI Video Card ? Any way to use usb port to use usb devices ?

Usb port is it locked or there is possibility to use it like usb host ?
To manage copy pictures of a camera to phone without pc by usb adaptator.
Samsung talked about usb 2 hdmi cable and think if its real it use some usb video card supported by phone(because of physic material imcompatibily of hdmi nd usb)
May there is a way to dev a tool or hack to get it works...

Aah!! Finally somebody like minded!!
I had been scouring forums for something like this. USB OTG would be an excellent add on to this phone. If not OTG, at least host would be an excellent idea.
No idea whether the existing USB Host driver for Nexus one would work on this one.
The processor on SGS already supports USB Host (not sure about OTG though). This has been pointed out in their press release - w w w .samsung.com/global/business/semiconductor/newsView.do?news_id=1043
I am just wondering - should we request Samsung themselves via mass petition to open up this feature on SGS?

some USB devices might be compatible, like the 100/1000 Mbps USB to RJ45 plugs
those same ones works in Windows Mobile it should work as well for Android, however a driver will be required.
mouse and keyboard support should work out of the box
external USB keys for storage, or even USB mass storage devices should work out of the box as well.
usb audio... hmm... not sure what else at the moment

Hi AllGamer
Thanks for the reply. So how exactly do we get this going on SGS?
I am much more interested in having USB HDD support on SGS (hopefully without an ext power source - am I asking for too much? ).
Are you suggesting that the N1 fix should work here also? Can somebody help us with a "How To" to enable this on SGS?
Cheers!!

you can plug in any USB mass storage devices (USB hard drives) and it should work.
However, you might not get enough power from the usb port, you'll still need need power cord for your external usb hard drive.
I know on my HTC windows phones works like that, it should be the same for Android.
I'll try that when i get a chance.
you just a need a USB female to a mini USB male cable

yep!! you are right about power!!! I am trying to get a cable - hopefully in couple of weeks should have this.
but I am wondering if all this would work without proper drivers in it. Would SGS have USB HDD drivers in it already?

I can see one problem, You will only be able to use Fat32 drives unless someone compiles NTFS / HFS+ into the kernel. Ext3/4 is already done so I don't see many problems. What I recommend you do is get some sort of adaptor for Female USB > Micro USB and test it out with a flash stick or you can hack one .

Yeah - I understand the difficulties of having NTFS support outside the MS world.
I didnt know that ext3/4 were already a part of the kernel!! Is this by default available in all Android kernels?
For USB Host cable - I am guessing that this one can be used - http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250671106072 (same as what Sven used for N1 USB Host capabilities).
But I seriously doubt plug and play would work (that would be too much of an expectation! )
Does any body have that cable here, who can check out if SGS does actually work in USB Host/OTG mode?

Sven has try with a Galaxy another Host Driver

Hm what can we do with these files?
However, any news about this?
Maybe, we could ask some Galaxy S kernel developers about this.

How to Enable usb - on the go?

please tell me how to enable usb on the go . i want to attached my pen drive and my hard drive to my phone .

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.

Manual USB OTG working

Hi,
As you know, the Nexus 4 doesn't support USB OTG, meaning you can't use it with USB drives, gamepads, etc.. One reason is that the device doesn't seem to provide the neccessary 5V, the other reason is that it's not supported by the kernel.
So, I've been digging a bit, and now I can claim partial success! It's possible to supply the 5V yourself, and then activate USB host mode manually. It's a bit cumbersome, but for the beginning better than nothing. I tried a mouse and USB drives.
I should warn you that this is just a proof of concept and nothing that you'll want to use on a daily basis. Regular USB doesn't work properly while running this kernel, and I haven't checked battery consumption. Also this is based on Android 4.2.1, and if you have 4.2.2 you might not be able to make calls. That shouldn't be a problem as this is for testing only, though. Just let me say, I can't guarantee for anything, and I'm not responsible if you brick or blow up your phone.
You'll need:
- A USB OTG cable
- A USB Y cable to provide the 5V (It has two USB-A plugs and one USB-A socket.)
- My custom kernel
- Unlocked bootloader
- Android developer tools (adb, fastboot)
Load the boot image on your phone (this is not permantent):
Code:
$ fastboot boot myboot.img
Connect everything as follows (should be obvious):
- Y cable power plug (typically red) to the PC or adapter
- Other Y cable plug into the OTG cable
- OTG cable into the phone
- USB device into the Y cable socket
You need a remote shell on your device. Use adbWireless or similar to enable ADB over WiFi, then do:
Code:
$ adb connect 192.168.0.108:5555
(or whatever your phone's IP is)
$ adb shell
Now you should be on your phone. Do
Code:
[email protected]:/ $ ls /sys/kernel/debug/msm_otg/
and you should see 'mode' if the new kernel works. Now become superuser and enable USB host mode:
Code:
[email protected]:/ $ su
[email protected]:/ $ echo host > /sys/kernel/debug/msm_otg/mode
To disable USB host mode, use "none" or "peripheral". Note that at this point, I couldn't get it to go into regular USB mode. This means that MTP and adb over USB doesn't work yet.
Connect a device, and you should see more than two entries under "lsusb". Congratulations, your Nexus 4 has just recognized it's first USB device! If you install Stickmount (you have to sideload it since it's marked as not compatible), you can mount USB flash drives. Nexus Media Importer doesn't seem to work, though.
How does this work?
Basically, I just added the following line to the beginning of msm_otg_debugfs_init in msm_otg.c:
Code:
motg->pdata->otg_control = OTG_USER_CONTROL;
This enables the mode file in debugfs I use for mode switching. The next step would be to enable manual mode switching while keeping regular USB support, which shouldn't be too hard. Later down the line we can think about switching automatically on cable insertion, and maybe event getting 5V out of the device, but that would be a lot harder.
So, try it out, let me know if it works for you, and feel free to tinker around and improve what I've got!

Nice to see some progress going. Only thing that irks me is the Y cable though, kinda defeats the purpose of OTG to me...
Thanks a bunch for your work though!

You are a genius. :good:
Just connected a powered USB-HUB and a mouse to my OTG cable, flashed the kernel and typed the commands directly with a terminal app on the device.
It simply works !!!

Awesome development, one of my biggest gripes was the lack of USB OTG, I just assumed it was included as stock, that's why part of the reason I purchased this device.

This is awesome. Going to have to order some cables now. Since we have to supply power anyway, is it possible to support usb-otg + charging? Figure the phone is "too thin" anyway... I'll probably be making a 64gb microsdxc + battery case for the phone. Hello extended battery life.

Great work, I was just looking for this yesterday. Would it work with a USB dac (Assuming I had a powered usb hub)? Just asking because I think usb audio is often overlooked, and I would really like to have it.

Nice!

It would also be interesting to see if the slimport adapter allows otg pass through (their website says it does)... Then that's HDMI +charging +mouse/keyboard. Even miracast + mouse/keyboard would be awesome

I'd like to be sure I'm getting a good USB Y cable. I see a few on Amazon, some have the word 'Power' in them, some don't. Most don't have a red plug. Are there some specific characteristics I should look for in the description to know that it's suitable for this purpose?
Here's one example that does NOT say 'Power' in its description.
http://www.amazon.com/OEM-UTStarcom-USB-Adapter-Cable/dp/B002W8EDOM/ref=pd_sim_e_2
Thanks, CaptainMuon, for your terrific work!
EDIT: After reading Scorpio16v"s post (and watching his video...thank you!), I thought I would try with a powered hub, since I don't have the Y cable. Also, I used the terminal emulator instead of adb, as he suggested. YES! It worked with a USB micro sd card reader adapter (I had bought it from ebay specifically for this Nexus 4 since I knew there was no sd card slot). That required stickmount, as CaptainMuon mentioned. Then I tried a USB mouse, and that worked also. This is great!
I'd still like to know more about the Y cable, as I asked above, even though this other method worked well for me.

Wonderful!!

When I powered off my USB powered hub, neither the USB Micro SD or the USB mouse worked.

Greaaatt news and excellent development on this front sir.
I was eagerly waiting for someone to come up with a solution to this topic.
But coming back I've read in so many places that a kernel can be tweaked so as to supply 5V to the socket!!(I'm considering that is the problem here. With power supply its working).

Awesome, my one gripe with the phone is now (almost) gone!:good:
Any chance it it'll work with non-OTG cables/adapters (The plain USB host ones which don't have that extra pin)?

Just posting to thank you for all the time and effort you must of put in.

It seems to be charging in USB host mode. (In my Y cable, the +5V line connects all three plugs, so the phone gets juice too. Not sure if that's always the case.) We have to do some testing to see if it charges at normal speed, etc.

I guess, if it is supported on any other android device, it should be possible here. Would be great if someone with a DAC would try it!

Hmm, I don't know how you could make a Y cable that doesn't provide power from one end, and data from the other . It should work, but I know there are a lot of scam/poor quality cables out there, so I can't guarantee it. I've got this one:

Htc desire 626s usb otg capabilities?

Hi, i recently rooted my phone and used the Post in the forums to do so, here is a pic of the kernal and all that. My question is why can i still not use my otg? Downloaded host diag, checker, helper, nothing is working. Can someone please tell me where to go from here? There are spaces so i could post the url.
http ://i63. tinypic. com/24ys9z5. jpg

seems kernel doesn't have the driver for it also the phones board doesn't supply power to the cable so you would need a y cable to supply power. Im still waiting for HTC to post the kernel source so I can make the modifications I need to it. It's been almost a month since they said they elevated my request for the source to their dev team if its not posted in a week I'm going to write them again.

There is a app I saw the other day called "stick" something that enabled phones with no otg support to use one. It was in a YouTube video about must have root apps , sorry I couldn't help more than this. I did order an otg cable after watching it.

Ok, ill look to see if it works

Nope. Still won't work. Power must be supplied for it to be registered to the phone.

E]Well i bought a powered otg y cable plug in usb portto charger the other end to my phone and the other to my usb 128gb.. nothing
still diesnt detect but it does on my samsung . So it must be the phone not the cable

I had no luck with a powered Y-cable either. I got OTG to work with my XT894 only after connecting a powered USB hub to my OTG cable, then connecting a USB flash drive to the hub.

Can it be done ?

Everything is integrated. If you want to expand storage you can use an OTG Micro USB HUB an attached a USB 64GB flash drive, it will be bulky but works!

Of course it works, you can play movies directly from the USB flash drive. You will need to supply power to the USB drive, connected by wire or using a Power Bank.

Is a Micro USB Port, is the same as your charger. The one that you connect to your Tablet. Search and do some reading on how it works, is very simple but you have to understand how all comes together, there is information on this site also.
Once you have Android install on your tablet, it works the same as others Android or Tablet Devices.

I finally got a OTG Micro USB straight cable, usb on one end and micro on the other, try it out and nothing happens, is there a setting with the tablet that needs to be turn on or off ? thanks

You will noticed that the USB flash indication light starts flashing and a notification on the Left top side on Android tells you ( USB Storage in USE ). Then you go to the File Manager and you will see USB Storage, when you touch it you will see all the files on the USB flash drive and you can play your movies directly from there at the same speed as if were on the internal storage. When you are done, go to setting and storage and eject the USB Flash drive. Is very simple!

I don't see nothing since nothing happens once I connect it, though if I use the cable to connect to my computer I am able to see the tablet internal drive, but not to a flash drive from tablet to flash .

The HP touchpad or old devices do not offer power to the micro usb port, you need a Y adapter one to supply power to the USB flash drive and the other one for data.
That is why I said, do some research to understand the connection, which it clearly shows on the Amazon product.

That will work with devices that allow power out from the charging port. The work around for old devices is the Y connector, with the connector I posted you can use a USB Keyboard, a USB mouse and a USB flash drive all at once, turning a tablet into a regular desktop PC. Like I posted your ROM will work and you can play movies directly from the USB drive with no loss in performance, with only your basic ROM nothing else is need it.
You are very welcome and have fun!
