[Q] HTC One X USB OTG. How???

So, I preordered the HTC One X, bought an OTG adapter, an MHL cable and an Xbox 360 wired controller.
Why? So I could hook them all up and play games on my TV.
I think you can see where this is going...
There are many people here asking how to enable USB OTG, but as far as I can see, no clear solution.
Please help, I was so gutted to find it wouldn't work.
Info: Stock 1.28, Unlocked Downloader, CWM, root.

There is no USB OTG as standard though there are some kernels being developed.

The best bet will be get the source for your kernel and compile the necissary modules... At least, I think...

I saw a Kernel called Eternity mod which claimed to enable USB host mode, but after flashing it did not make any difference to whether or not it detects anything..

Hi,
I wonder is there a way to have USB OTG (like Galaxy S3) on One X ?
If so, please guide me the process.

Oh and regardless you can't use MHL and USB OTG at the same time.

How can it be????

samsung s3 works with android 4.0
one x works with android 4.0
why does one of them support OTG, one not. HOW?
same question about video calling over 3G (not via internet)

there is no usb otg as of now for htc one x, but we might get one in future.
afaik the htc one x hardware allow usb otg, but somehow htc has blocked it due to some silly reasons.
but i think so it will be enabled in kernel 3.1..

it depends on the kernel, not on android version.

[Q] Micro USB to Ethernet Port Adapter for Galaxy note 2

Just wondering if there anything out there that would work? Is there drivers within Jelly bean that would allow me to do this? Any help would be appreciated.

Could you use a otg cable and a normal usb to ethernet adapter? Don't know if something like this is supported though.

But why u want something like that while u have wifi and kies air? What thinga u canot do through wifi?

I don't want to use WiFi because i don't. Simple as that.
Have anyone found something to solve this problem?

Yeah,
That would be a welcome feature if possible. Can't get wifi everywhere.
Cheers

Yea, I just tried it right now as I just received my usb-on-the-go and did not work. Its the same usb to ethernet dongle that I've used on my Transformer. (http://www.amazon.com/gp/product/B003VSTDFG)
I am hopefully getting the dock for this thing and wanted to use this as a full blown computer with ethernet. Hopefully someone can get it to work.

It might work but might have to be built right in the kernel...hmmm...looks interesting though.

My Note 2 will actually light up the USB Ethernet adapter and show a link to the network switch, but there doesn't seem to be any 'Ethernet' connection usage option with the Note 2 as of yet. I was under the impression by default Ethernet functionality was part of ice cream sandwich and jelly bean, but it appears Samsung has removed it.

My experience has been exactly the opposite. Most Android kernels (and almost all stock ones) do not come with drivers that support most Ethernet chipsets, even kernels that support OTG. While these drivers are usually easy to find in Linux source code, very few flashable kernels compile them in (It's not hard if the kernel builder chooses to include them in the build tree).
I have two inexpensive USB Ethernet dongles and have had a very hard time making either work. While waiting, I have resorted to getting a small traveller's portable Ethernet hotspot/router such as the TP-Link WR3020. That works fine and has the benefit of supporting multiple devices off one Ethernet drop without needing a switch.

There are still many hotels and offices that use wired Ethernet and don't have wifi. So if you want to replace a laptop with an N2, sometimes you need to be places where there is an Ethernet drop, but no wifi (and either your SIM card doesn't work where you are, or roaming is horrendously expensive).
If you travel frequently, it can happen often enough that you need either an Ethernet network adaptor, or a small wifi router.
Also: even if not travelling, you can't break into a wired connection quite as easily as a wireless one. Wired is often faster and certainly more secure.

I need this Ethernet-over-USB functionality. I believe it is called CDC-ECM. When I have built a Linux kernel in the past it was included with option "Multi-purpose USB Networking Framework"
Does anyone know of a kernel for Note2 (N7100) that supports this?

I asked the same question. http://forum.xda-developers.com/showthread.php?t=2115186&highlight=ethernet
And no one answered. I need this functionality too. It seems nobody can help.
It`s only way to ask ROM builder to add these features to their products, i think.

up for this thread.. i need this functionality also

To confirm the above:
Yearsterday I received USB to RJ45 LAN Ethernet HUB internet Adapter (ebay.com/itm/USB-to-RJ45-LAN-Ethernet-HUB-internet-Adapter-for-google-Android-Tablet-pad-Tab-/250894821624)
It does not work with my Note 2 (GT-N7100, Omega v12 - XXDMB2), although it works great with ASUS PadFone2 and with desktop (windows7 64).

Micro USB to Ethernet Port Adapter for Galaxy note 2
Hi folks
usb to ethernet seems to work on Android for some, I guess hardware and operating system (embedded drivers?) have to match this device
For my Asus Transformer I can use their ethernet adapter by simply plug it in.
On my Samsung Note 2 JB 4.1 nothing happens...
Would rooting help?
Anyone managed to have it work?
I know that wifi is a much easier method but it's good to know it doesn't work on this device :laugh:
Sorry for my bad english, I'll try to improve
these items works on the Transformer with JB 4.1

I don't understand people, who think: if i don't need it, nobody need it.
I bought note to use it on work. Ideally it should be used instead of a laptop.
The problem is that I am not allowed, for safety reasons, to use wireless link.
And actually it interesting to make it work.
But thanks for the tip, in other way it can be useful.

As discussed above it did not work with N2.
I think Renthal (message #8) and el56 (message #9) are right.
We need kernel for Note2 (N7100) that supports this feature.
But still nobody has found the ROM or Kernel for GT-N7100, which correctly work with USB Ethernet adapter.
Only root will not help.

I have a second device, a Nexus 7, which (unlike my N2) is rooted. The stock kernel in the Nexus 7 does not support Ethernet-over-USB, and many third-party kernels also do not. However, I did find one kernel -- "Bricked" -- that did. Since installing that kernel, that device now works very well over wired using a $2 OTG cable and a $4 USB Ethernet adaptor (both bought on eBay)
(That setup actually worked in a real-world situation - a hotel in Beijing, that has only wired Internet - in which a Wifi Ethernet router didn't work because of post-connection login requirements.)
This experiences confirms the contention that the drivers for Ethernet-over USB are *available* for Android kernels, but that stock kernels (and most auxilliary ones) have chosen not to implement them. The answer for Note 2 users is to convince Samsung (or, more likely, custom kernel builders) to enable Ethernet drivers that already exist.

I remember seeing patches for Honeycomb stock kernels for numerous devices that add alot of drivers. It maybe feasible to compile the kernel modules and insmod them, if we have kernel sources. Do we have them? Hellllllooooo?!
And I'd like to have this functionality. To all people wondering why one would need to use such *cough* ancient *cough* technology as wires:
At my workplace there is no 3G coverage (hell, it struggles to connect to EDGE, falling back to GPRS, voice calls also suck), and we're not allowed to use any kind of WiFi or Bluetooth or any other radio, including wireless mouse/keyboards (corporate industrial network sucks all the channels, anyway), but we're supplied with wired, unfiltered network going straight to internet, just for sake of having internet on our devices (my work consists of cycles 1-2 hours of intense coding, and 1-2 hours of empty waiting for tests), so we won't get bored to death. So.... I want my ethernet dongle working! http://freeware.info.pl/software.html

Yeah, I really need that feature too.
I have 2 young daugthers and my wife doesn't want to hear about wifi or 3G at home, cause of health concerns.
And in addition, I work in a company where wireless connections are not allowed for security reasons.
So Ethernet connection through USB adaptateur is almost the only option for me.
But isn't it possible to install drivers on an androids smartphone, as we usually do on PC ?
(Sorry for the newb question)

[Q] Is there is a ROM or kernel (or ROM/kernel combo) with FULL USB Audio Support?

I'm a relatively new owner of a T-Mobile Note 2. Love the Jedi Master ROM. But I'm still facing my ridiculously frustrating scenario where I have this phone (and a tablet, the Nexus 10), that I want to use my USB DACs with (Fiio E07k and Hifimediy Sabre), but can't unless I use the awful USB Audio Recorder Pro App. I just want to plug in these DACs (via OTG) into either of these devices and enjoy music without having to use that aforementioned app.
Anyone know (for certain, i.e. through personal experience) of a current kernel and/or rom (or rom/kernel combo) that provides FULL USB Audio support for the T-Mobile Note 2? If not "for certain,," how about just from rumors?
Thanks!!

+1

I'd like this option also, but in the meantime, have you tried viper, with the correct IRS file for your headphones of choice.
It's a pretty good alternative to an outboard dac

The issue is not using a USB drive, it's USB Audio, i.e. T-Mobile Note 2 >> USB OTG >> Fiio E07k USB DAC >> Audiophile quality headphones, and not using the USB Audio Recorder Pro App to get that setup to work but rather using that setup and listening to music or whatever through any app. Android phones since 4.0 are capable of this, but I think something in the kernel has to be enabled.
Timur on Rootzwiki did just that for the original Nexus 7, but nobody has stepped up to the plate to do it for many other devices, such as T-Mobile Note 2 (unless I'm mistaken) and Nexus 10. For either of these devices, I'd pay for someone to customize a kernel to allow this.

After more testing, it turns out the problem was the cable. My SGH-T889 works awesomely with my Fiio E07K, in Tweaked ROM with Saber kernel. Not intermediary apps, ask the sound is redirected to the DAC no matter the so you are using. Hope this helps.
And when you don't have the Fiio, Voodoo sound plus DPS manager does the trick as well. I love this phone.

Ashade's suggestion of Tweaked + Sabrekernel did not work (I tried it today. Even tried tweaked by itself and with some other kernels). Thanks for the suggestion though.

A few weeks ago I got my Nexus 10 to have full USB audio support using a modified CM 10.2 rom. I think the CM guys did something to fix the USB audio issue and I think that's why the rom I am linking here works (so I would suspect CM 10.2 alone would work too, but I don't know that for sure), but man oh man it's awesome to have full USB audio support from my T-Mobile Note 2!

That's weird... I'm still running that. What DAC are you using? It works perfectly with both my Fiio E07K and O2+ODAC combo.

So I didn't update Saber in a while and I noticed they drop voodoo sound by boeffla and some other changes. Maybe that's why it didn't work for you. I'm gonna recheck it with the current version and report back.

Tried it right now with the latest versions of everything and it works flawlessly. No problem whatsoever. It's pretty weird that we are getting different results...

Fiio E07k, but I saw a few of your posts on Head Fi where others said it didn't work for them. What's really funny is that while I ran tweaked + saber for a minutes, one time I put on Google Music and got audio out of my Fiio E07k. I was ecstatic and then tried it again, nothing. Very weird but the rom I linked works perfectly, and is CM 10.2 based, just like the ROM I put on my Nexus 10 Tablet, which also works perfectly now.

Good to know you got it work with something else at least.

4.4.2 enables USB audio out!

Well I am extremely happy right now.
It turns out that with an OTG cable, my 4.4.2 RAZR M can suddenly output audio via USB to my Fiio E17 amplifier. I can finally ditch the 2G iPod touch I have been clinging to for years.

I am just starting to explore the possibilities of using my M for high quality audio. Does the above work without root, custom rom, etc.? I am not rooted and am bootloader locked and need to remain that way.
Are there any decent guides available on the net on this topic? I have been doing a lot of googling and trying to piece things together but haven't found a good consolidated source for information.
Thanks much.

It's called 'class compliant' USB audio device.
If it works on Windows, Macintosh etc. without the need to install a device specific driver, it's probably class compliant.
Btw., the support for OTG connected class compliant USB DACs has been present in CM builds for Razr M/HD family since September 2013.

:good: Was able to pick up for a whopping $1.04 shipped, a USB audio dongle from eBay which works great, but needs external power.
Now if only I could get PodMode to work, I'd have a perfect 1-plug replacement for an old iPod.

I think Timur has been the only one to work on that. And you won't find much more info about it on xda because he charges money for his kernel.

How about a hardware mod?
Can I maybe add a dedicated charging port that doesn't rely on the microusb connector?
I don't like how timur's kernel has to be used with stock, I'd rather use CM11/CM12
Maybe it is possible to fake the Qi receiving pins to take a hardwired charge.
