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.

[Q] HP Touchpad CM7/9 USB Audio Support

So I've been trying I find a solution for this, but it's been proving difficult. I have seen that on the nook forums, with a quick kernel mod and a tweak that allows USB audio control (i.e turn on switch for USB audio output), the guys over there have working digital USB audio output to an outboard DAC. Could anyone find out how to do this with cm7/cm9? Cm9 preferably. I assume we have basic USB host capability, since keyboards, etc. work, so its something specific to USB audio. This is definitely one of the only issues I need resolved on my TP.

This is very possible with USB host and OTG Y-cable adapters. When my cables and my computer come in the mail I will try tinkering with it. It'd be nice to see Jack audio running on here. Once July rolls around and HP releases most of their driver and kernel sources, development in all areas will skyrocket for our Touchpads.

Does the upstream port require power even if the device I'm using has its own power? My E17 has its own battery, but for some reason it isn't even recognized through the USB OTG cable. I can't even get USB audio to work on the WebOS side, which supposedly has full USB audio support via pulse audio now...

Hmm, I'm not sure. If it has it's own power supply, maybe you can try to mount it with a standard male microUSB to female USB. I'm about to see if I can get my external HDD with it's own power supply to mount to my phone and tablet. Will report back with results.

Yeah, no go on mount :/

Has there been anymore dev on this topic, including the current CM mods? This would make an interesting project for a carputer if the USB audio works.

[Q] Sony Xperia T haven't OTG official?

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?

OTG with USB DAC

Hey All,
I'm trying to get my N6 >> OTG >> DAC setup working.
Previously, I was using a Note 4 and this worked just fine. Exact same setup.
On the N6, I'm not getting anything; no output. I'm using USB Audio Player Pro and it does not detect the USB audio device that is my DAC. If I use Neutron or Google Music, it just out rights output to the N6 speakers.
I had a split second of success when using a USB hub that was externally powered, but it stops after a second of audio. If I go straight from the N6 to DAC, I get nothing.
Everything is pointing me to the lack of power output from the N6. I suspect the Note 4 provides more amps?
I found a reddit thread that said they disabled USB charging somehow and had success, but they didn't elaborate on how it was done.
Any help and feedback us much appreciated!

Maybe the fact that the Nexus 6 is not host (OTG) - compatible can help you ?
I don't know how you can make it OTG-compatible, but if you have a way to do this, I would like to know it

USB Audio Player pro works just fine playing 192kHz Flac files through my AudioQuest FireFly, not sure why youre having issues....

I've tested with and Audioengine D1 and a JDS Labs ODAC. Both failing. OTG works, because I can connect USB mouse and USB storage just fine.

Samsung's give out much more power than Nexus devices. Samsung can power a mechanical hdd via OTG where as the nexus generally can't.

Is this something specific to Samsung hardware? Surely, there must be a way on the Nexus. It's essentially a battery and a USB port.

It was originally specific to Samsung. The S3 was the first device able to power a USB HDD.. Whether more devices can now or not, I cannot say.
That's not to say every device that needs power won't work, just those that need more power. I'm sure other usb dac devices work.. Whether yours needs more power than those, I dont know.

like I said, its working for me...so it could be the DACs you have require more power than the NX6 puts out, or maybe it just doesnt like the OTG cable you are using. try another that you know works

With that theory, I should be able to power any DAC using a powered USB (dedicated source) as a buffer. This worked momentarily for the Audioengine D1, but then it is cut-off. I've read somewhere that some DACs will try and detect if the power is from a "self-powered" source. Not sure where I'm going with this as I don't expect a work around. Just wanted to mention that note.

Try with a powered otg cable. Like this; http://www.amazon.com/Micro-Cable-Player-Samsung-Galaxy/dp/B00CXAC1ZW
One plug to charger, one plug to phone, device in the last.

Just where did you come up with that absurd idea?
While the factory firmware is not configured to mount a usb disk, the device and kernel are both most definitely otg ready.

I've ordered a view different cables to test. Hopefully they will come soon.

Sabre DAC USB Not Detected

Hi all,
Is anyone here using the Sabre DAC on the HTC Memul?
my Sabre DAC Works on my HTC M8 but not on my memul!
its even not show using "lsusb"
i just got the USB-C Version of the Sabre DAC and replaced the
cable with a USB-OTG one, tested on my M8, works but not on the Mini 2.
In one Thread i read that the memul supports USB Audio and someone had success with a different device
but in another thread i also read that the memul wont support it.
so, whats true now? what can i do to get it work?
i'am capable of smd/smt reworking , so if there is a mod on the device itself, let me know.
I also read that there are issues with android 7.1
thx for your help!
