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.

Using NC to upload pictures from camera during travel...

Hi all,
I am taking off for a month long vacation to Asia and India soon and am having a tough time imagining my life without a functional computer... so, what better alternative (along with my 3G phone) than then Nook Color...
but...
One of the most appealing concepts to me would be to use the NC as an "uploader" of pictures I will be taking with my SLR.
So, can this be done:?
1. take out MicroSD card from Camera and somehow, with some adapter, connect via the USB port on the NC.
2. Use an app to mount/view the MicroSD storage unit and copy to the NC storage, some/all of the pictures i want.
3. Use the SmugMug Andoird App and WiFi via NC to upload pictures while I travel.
>> I guess i could do this via the the mobile phone I'm bringing, probably by swapping the memory card on the phone and using the same app, but i believe the larger screen size and easier text input would make the NC perfect for this.
Thoughts?
Thanks ahead of time.

Check in the development section for the thread on usb host support. It tells you how to hook your camera to the nook with a usb cable, I've never tried it but a lot of people swear by it.
Sent from my ADR6300 using XDA App

I have NC with CM 7.1 stable on EMMC. I am able to use an unpowered USB card reader to transfer pictures off both full sized and micro SD's. Other than being on CM7 the trick is getting the correct cable. Here is the one I use:
Micro USB Host Cable (OTG Cable) - Xoom, Galaxy S2, Nokia N810 / N900, Toshiba TG01, Archos G9. New Version with more accommodating "L" shaped connect
Off Amazon.

You'd probably be better connecting directly to your camera, if your camera can do it. For many things connected using USB host you need a powered hub, but since the camera has its own power it probably doesn't need the hub.

There's also at least one raw format decoder called RawDroid.

I haven't tried this, but I imagine you could use a microSD to SD adapter and just use microSD cards in your camera. Take the microSD out of the adapter, put it into the Nook and copy the photos over with a file manager. This would obviously cost you more money, as microSD (I believe) is more expensive than SD, but it would save you some hassle on the Nook side.

There are few ways to get this done but b4 trying one, make sure you meet all requirement.
1. Some members suggest you swapping the uSD. It's a fastest way BUT make sure you are running CM7 off eMMC if you're booting it off the uSD itself, then forget about this method.
2. If you Tx pix directly from camera to NC, make sure you do have the microUSB-to-whatever your camera USB connector type: miniUSB or USB, cable.

Awesome tips guys, thank you.

Can't imagine what that would be useful for unless all the shooting is done in RAW and you want to preview or something...

This is what I do. Micro-sdcard w/ adapter in my Canon. Pop the card out, and put into the NC (after first uninstalling the card I normally have in there).
view pictures, copy them to internal memory, etc.
As stated above, you must not be running CM7 off the sdcard for this method to work.
I think it would also be possible to plug a flash drive in using an OTG cable (w/ power) and backup to that as well - I haven't tried that yet.
If you wanted to run cm7, you should be able to do the opposite - sdcard into a reader plugged into NC using OTG cable (w/ power?) and then copy to the sdcard that you are running cm7 from.

wow im interested in this, but do we really need a otg cable? since cm7 comes with usb-host support?
btw can the nc supply enough power to the card reader? or a 1-to-2 splitter so that the nc can be charged at the same time?
and what apps are suitable for this kind of usage?
wow the ipad got something like this already: http://terrywhite.com/techblog/archives/7657
but ipad are much larger... needs a backpack, nc can fit in a large pants pocket.

That's the cable that works for me. Plenty of power for the card reader.

i also use a microSD to SD adapter in my camera, and pop the microSD to copy the files in the internal memory of the nook (then, as i am a freak about not loosing my pics, copy them from internal memory to 2 backup microSD's)
i dont know if it impacts in anyway in the performance of the camera, i shoot with a 12 megapixels canon powershot in jpgs and 720p videos. i'm not very exigent with the transfer rate of the card

it seems that quickpic (https://market.android.com/details?id=com.alensw.PicFolder) is a good (and faster?) alternative to the built-in gallery.
what is needed... (for people who need to use a card reader) since the nook can only supply 100ma power...
1. a y-splitter cable (where can I find one? are there ready made ones?)
2. a usb charger
3. a microusb male to usb type-a famale
4. a card reader, of course

The cable I mentioned and a card reader work fine for me, no need for additional power.

[Q] Nexus 7 Question - How to add more memory

Hi Everyone,
Sorry, to post this here but I couldn't find a Nexus 7 (new Google Tablet) dedicated forum.
I have pre-ordered an 8GB model for a friend of mine over-seas in a place where there is no internet (not so easily available). However, they do use USB keys to transfer data, videos, pdfs, and music back and forth. Since the tablet doesn't have an SD Card slot, how can the USB port be used to transfer files say from a USB key? Would that even be possible? is there a converter for USB port to mini-USB port?
Thanks

Here is the Nexus 7 discussion group:
http://forum.xda-developers.com/forumdisplay.php?f=1673

Yes, there is. Look up "Stickmount," by Chainfire. Apps cannot be run off it, but it is free and only requires a cheap OTG cable.

Is it possible to plug a USB memory reader directly into N7?

I would love to be able to plug a USB reader into my N7 so I can pull photos off my cameras memory card while travelling. Is this possible? More than happy to root if need be.

With an OTG cable, yes. Without No.
Lookup OTG in the nexus forums for more info. Requires Root to use the utility that enables the use of the cable.

After rooting and installing stickmount you can use the reader,flashdrives or just plug the camera in with a usb cable and view or download your pictures from the camera card.
I rooted just so I could use the N7 to check my gamecams without carrying a laptop in the woods.It is a little slower than the laptop when your are looking at 2 or 300 photos but works well to view and pull out the ones you want to save.I pick out a few good ones to keep and clean the camera card for the next week.

OTA ICS: USB Disk mount?

when looking at the storage control panel, it lists internal, sdcard-ext, and then "/mnt/usbdisk_1.1.1" and says "insert an [sic] USB disk for mounting".
so if i were to come up with some sort of adapter, could i plug a thumb drive into my phone's micro usb port to move files between the phone and the thumb drive? i can think of plenty of times that would be useful!

Tried. OTG cable works with Samsung galaxy S2 devices (Skyrocket using either SKY ICS or rooted OTA) but haven't got it to work on our Droids...(Bionic ICS leak, RAZR ICS OTA, Droid 4 ICS OTA...all rooted).
But if someone can prove me wrong I'd be happy to "eat my words" ...

OTG works, BUT only in a very cumbersome way, since external power is needed.
A powered USB hub does not suffice, since it only powers the slave devices, not the host (= phone). The phone must be in charge-mode, which requires a Y-cable.
You need:
- an OTG adapter
- a USB hub with mini-USB in
- a USB Y cable with 2 normal USB plugs and one mini-USB out
Then
1. Connect the OTG adapter to your phone's micro-USB input
2. Connect the 'middle' USB plug of the USB Y cable into the OTG adapter
3. Connect the 'outer' USB plug of the USB Y cable to a charger (can be a portable battery as well)
4. Connect the mini-USB plug of the USB Y cable to the hub output
5. Connect any device you want to use to the USB hub
It looks like this (found this picture for Razr):
http://www.flickr.com/photos/teppan_hakushaku/6817735705/
Edit: I verified it for Droid 4 last week, but didn't take my own picture yet. Works with ICS .215 leak, no 3rd party apps (like 'StickMount') seem to be needed.
Edit2: According to some other posts in this forums (search for 'OTG') it will only work for FAT32 formatted drives. Didn't check this in detail but my drive was already FAT32. Also I found it did not work for my cheap wireless keyboard's USB dongle, but connecting a wired keyboard worked fine.

...reminded again why I love this community...
...no possible links to a purchase of this "y" cable?

Glad I could help!
They come with some portable harddisks, so that's where I got mine. Not sure about the linking policy on XDA, please remove if not allowed. Here's an example:
