I tried looking for details about USB OTG but unfortunately i didn't find much. If anyone would tell me is USB OTG a hardware+software feature or is it just a software feature?
Because what i am thinking is maybe if it is a software only feature someone could somehow develop such a software to enable USB OTG in our lovely OB!
Thank you for time and efforts.
It is definetly both: hard and software.
Normal usb hardware for mobiles only allow usb as a device. If the mobile has only such a port, no software can turn this port into usb host mode!
Hardware must enable the usb otg specification, wich allows usb in both mode: host and device.
But even if a mobile has the hardware usb otg port, maybe the software will only allow usb in device mode. Motorola atrix for example has the hardware feature but allow the otg mode only with tricks.
If lg p970 optimus black has the hardware possibilites for usb otg, i´m not sure. I personaly think that this is misssing, because you nearly find nothing about this in the internet.

I know it is in the wrong place but there is already a thread about it
http://forum.xda-developers.com/showthread.php?t=1445336
Actually there have been few threads but no developer had taken interest.
I stand corrected
Aprold said he will have a look if it is possible to be enabled.
Can a MOD unite the two threads and move them to appropriate section please?

hi i was wondering if anyone out there new if there was an SDIO USB HOST card, similar to the shown on the link below (but obviously SD not CF)
http://www.ratocsystems.com/english/products/subpages/cfu1u.html
if not, does anyone know/have tried the above CF to USB Host with a standard usb webcam and got it to work? if so can you explain how i go about setting it up.
thanks

i'd suspect that the fact that usb to host have to supply 5volt with 0.5mA
it could be an issue for something as thin as an sdcard
also not sure if the sdio interface even operate at 5v
usb host
I haven't seen an sdio to usb card, but I use my "htc universal" with it's mini usb as a usb 1.1 host. It works ok but you have to supply external power.
if you have that working you are the first and only person i know of who gotten any htc device act as usb host
sure there were rumors that it would do host
but later on ppl retracted those claims
After wiring up a cable for that, how do you set the phone to 'host mode'?
Thanks
usb host is not a mode
your pc is in host mode always
as are the 2 htc devices which do support
usb host out of the box
is a device is connected and the driver
is present the device works
Nope, USB host is a mode. It's the whole Master / Slave affair. Granted, it's automatic for most devices when another is connected... ah... that ought to answer my question I guess.
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
h t t p : / / sven.killig.de/android/Galaxy/
Hm what can we do with these files?
However, any news about this?
Maybe, we could ask some Galaxy S kernel developers about this.
I've seen this done with other Android devices (ie. Droid), but I haven't seen any mention of USB-OTG or USB Host Mode around here... so, just a quick question for the actual gurus around here:
Is it possible to unlock/open/use the microUSB port to connect USB peripherals to a NC? (keyboards, microphones, etc)
Thanks ahead of time!

Does anyone have info on this possibly being in say... CM7?
http://www.slatedroid.com/topic/15979-hack-enable-usb-host-mode-ie-thumb-drives-on-the-xoom/
this looks like the source for the sites claiming to have usb host mode guides on the xoom, but it doesnt look like more than just usb drive support
It's in the works.

Dear Folks,
Is it possible to make X8 compatible with USB host stuff?
I want to plug in pendrive and use DSLR Controller app https://market.android.com/details?id=eu.chainfire.dslrcontroller
Who knows?
Thank you!
our kernel inst compitable.
but if he is we can connect usb keyboards, sticks and mouses
(if you have the right software
Plz tell me: No. Thats have support of otg fabric.
I have no idea what it is you're asking, but if you're asking if the Xperia T has support for USB-on-the-go the answer is YES. Xperia T supports USB OTG by default. I used it on mine today to restore a backup from a stick.
i can confirm too... otg works..

So then it is weird that usb host diagnostics says it does not work on the LT30p?
Or maybe there is a problem with the test procedure for the diagnostic app?
I am looking for a phone with OTG (maybe cheaper than the T), and my two sources are XDA-dev and http://usbhost.chainfire.eu/, and sometimes they do not agree...
Maybe someone with a T should try a test with the app and report it to the host diagnostics dev, as I thought chainfire's site was a great source for info.
I also have the same problem as OP, i made my OTG lead by cutting a usb extention and splicing into another usb extention in effect creating a Y usb with females on both ends, the reason its a Y is so i can add power to the cable from the male end and not have to chop up my usb micro-b cable, this worked perfectly on my htc hd2 with usb host mode files enabled but doesn't seem to function on the Xperia T, i'm running the NXT r2 rom which is based on stock so usb otg should work right?
