All,
The last post I saw regarding this topic was back in May and I want to see if there have been any updates.
I want to get USB ethernet working with this device but it appears it is not supported. Is this true? Only on stock kernal? Are there modded kernals with USB ethernet support?
TIA,
AL
I think you have to go back to gingerbread if you want that feature.
No idea how difficult it would be to implement but I imagine it is too much work for little reward.

Hi all,
I did a few searches before this and it seems like no one else has asked about this yet. My goal is to get some type of external radio working on an Android phone in hopes to learn more about the system and possibly get a USB LTE radio talking to Android. I know most of the phones use usb Micro which supports a host protocol but I don't know if the Android system supports it.
My first goal would be to get a usb wifi dongle or 3g dongle working. My reasoning is because those have linux drivers so maybe I could try to get the driver on the android phone? Just my thoughts.
Does anyone think this is possible? Thanks for any help.
PS: I am aware that I would need an adapter to make the dongle fit to the micro usb port.
SO far I have been able to get host mode working on a nexus one. Now I need to get into adding different kernel modules compiled. Does anyone know a good guide to follow to ge me started? I did a quick google search but it didnt really turn up anything other than compile the actual Android Kernel.
Hello everyone,
I have nothing even close to development knowledge, so I have no idea if and how this can be done. Seeing what you guys cook together here though, I am quite sure that what I request should be possible.
As most of you will know, Samsung has removed the USB Host APIs from it's newer firmwares. No one kows why, but a lot of SGS2 owners, including me, dearly miss that feature. (I need it for chainfires DSLR controller)
I love to flash the newest firmwares, am eager to see whats new, and want the improvements they bring. So what I'm asking for, is for someone to "extract" that usb host-functionality from older firmwares and put it in a (cwm flashable ?) package that enables the funktionality for any firmware.
Since our hardware supports it natively it should only be question of software/kernel, right? Would love to see this happening... would hate to flash back to an old firmware.
Any help welcome! Would buy people bringing a solution a beer! cheers
works fine for me on KI3...? I use the usb host function often to transfer photos to a usb for work..

I don't really know how it works, but there seem to be different functioanlities. The new firmwares still are usb host enabled, which means you can still connect thumb drives, etc.. though as chainfire states here: http://www.chainfire.eu/articles/103/_SGS2_KI_Samsung_removes_USB_host_support_patches_bootloaders/ 3rd party aplications have been blocked from making use of this functionality.
no one?
...well I guess if it could be easily done chainfire would already be on it. please let me know if anything comes up!
there is a thread concerning this in the epic 4G forums. seems like they don't get usb otg at all, which is why that problem generates some more interest over there. chainfire himself contributes to their discussion. for everybody interested, let's follow what's going on over there. if they find a solution i'm sure we can apply it to the gs2.

Greetings! I've been lurking on XDA for quite some time, and first I would like to give a big thank you to all the developers. I would never have purchased a Kindle Fire if I didn't have faith in your ability to unlock the hardware's true potential. You guys/gals rock.
Here's my question: I develop and troubleshoot municipal and commercial wired/wireless networks and I would really like to be able to use the KF with backtrack. I understand that OTG support under ICS is very close to being a reality, would it be possible to support an external wifi adapter via OTG?
Drawing power is the first problem that comes to mind, so my thought is to mod a USB OTG adapter to draw from an external DC source instead of the KF.
This could have some awesome potential if it could work. I'm willing to do whatever I can to make this happen, so if one of you veteran developers could set me on the right track to backtrack it would be greatly appreciated.
I'm no wifi/kernel expert but as far as i have understood it:
It should be possible if you get the right wifi modules to work. Android uses a modified wpa_supplicant, so even if you have linux wifi drivers for usb you would need to patch them to get it running. The current kernel does not have mac80211/cfg80211 modules compiled it, but i think that you probably would need them (i think they are in the kernel source, they are just not set yet). The current module for the tiwlan is proprietary and is also uses some strange ibCustomWifi as wrapper around WEXT, not sure if they also did some changes there.
If the 3.0 kernel boots we should anyhow change to a mac80211 wifi driver and also use wpa_supplicant 0.8 instead of 0.6 so your chances should be a lot better with the 3.0 kernel.
So it strongly depends if your external wifi adapter is very well supported for linux (or better for Android ....) und if we get otg running. (There might be some hidden problems to discover).
Sengwall,
There are several threads in the xda forums for similar projects on different devices that might be useful as the steps are basically the same (assuming that somebody gets OTG working). Here's one of them:

Thanks for the input...ill look and see if there has been success on other devices with the same board.... great suggestion.
hey guys and girls;
for various reasons i want to be able to use cat5 with my tablet, i have found this:
www.amazon.com/gp/aw/d/B007RTACDM/ref=aw_d_detail?pd=1
but it says it wont work with samsung as they dont support wired internet, is that something that is in custom roms? i was planing on using a dock, maybe with a otg usb connector or something, is there a better way of getting cat5 on my tablet?
if not, has anyone had much luck with other tablets and what im trying to make happen?
Hi everyone, I bought the SM-T230NU while on holiday and just tried to use it with a USB to mirco-USB adapter, only to realize this tablet doesn't allow USB host !
I'miss a little pissed and after scanning through the XDA forum I'm still not certain whether the root will allow me to enable this function, could someone let me know if they've found a solution to this ?
I would just like to be able to read USB flash drives directly off of the the tablet, nothing complicated, I can'tell believe Samsung would forget this function on the 7" version but include it on the 8"!

I just became a xda user, so just trying to help out by replying...
You've probably seen this thread by now, but lists details of how to detect USB host support.

I don't think root will give access to USB OTG if it doesn't support this feature out-of-the-box.
It sounds like a kernel customization functionality which is not a simple solution that you are looking for.
In a round about way....
Persistent Root will allow custom recovery> will allow flash-able ROMS> Will allow custom kernals> Will allow OTG.
tab4 7 currently has the first two but no source for the second two. So currently, no OTG support.
I just purchased one (yesterday) due to size constraints, and its the cheapest(only) 7" tablet I could find that was less than 111mm wide. But my application that limits the size also requires OTG. So here's hoping that the most excellent and smart peoples of XDA can pull through for us.
Flashable ROMS for SM-T230NU ? are you talking of the flashable Stock Roms available on this Sub or some other custom Rom I'm not aware of yet?
No, it seems that the poor tab 4 7" has both a root and custom recovery, but alas, no flash-able roms or custom kernels. And I've all but given up hope that there will ever be any forward progress on this device. Seems that when knowledgeable (in this area) people find out the hardware in the 7" they just return it for the 8". I have a space limitation that very specifically necessitated the use of the tab 4 7" so I bought it and used it in the hopes that there will be development for it in the future. Doesn't look like there is hope that will ever happen. Mostly I just need OTG + Charging ability.
Maybe when prices get low enough for the 7" I will just buy one and send it to a well known developer to see if he can do anything with it. Still, even then, if there's no way to do anything with it...
