USB host

I've been searching but I haven't been able to find an answer...does the hd2 support USB host while running android? I'd like to b able to connect a web cam to it...I've have also found Bluetooth webcams, also wondering if using one of those with the hd2 would b possible....I'd just like to b able to video chat with the hd2 and I wouldn't mind carrying an attachment....

Hello,
Is there a chance to have USB host on HD2 under android builds ?
If not can we know what is the main problem ?
Android is based on a linux kernel isn't it ?
So, if USB host is supported under linux builds, why is it impossible on android ?
Thanks to teatch me !

I don't think android in general allows USB host on any device... that's the problem. The linux kernel supports it, but android doesn't. If you use ubuntu you can have usb host on the HD2.

Actually, the Notion Ink Adam runs Android and has USB host mode. With a bit of kernel hackery, this could well be possible on the HD2.
Using a USB Y-cable and providing external power, it should be possible to connect all sorts of things. I'm patiently waiting for this capability as I have a USB SSD HDD that I connect to my car's head unit that I'd like to connect to my phone when I'm at work

You're right, I have seen other android tablets with usb host, too. I remember seeing the devs explain somewhere why android on the hd2 doesn't have usb host... I thought I remember it sounding like it wouldn't be able to happen until a later version of android... but I could be wrong or misunderstood. I'll try to find where I read this.

Hi.
http://forum.xda-developers.com/showthread.php?p=10797562
It's an easy way to use the USB connector in host mode, works under ubuntu.
with some adaptors you can build it also by using an y- cable.
But I think android for HD2 doesn't support anny usb features until now, perhaps someone will activate it in the kernel.

Yes, most of us are aware that host mode is usable whilst running Ubuntu. The problem is that Ubuntu is not really convenient as a main phone OS; Android is and some devices seem to have host mode while running Android.
Hopefully one of the devs will see this thread and give some insight.

Because tv has hdmi input and laptop has hdmi output. You are trying to output hdmi from your phone which should go into the input. Since your laptop is not an input you cannot and will not see anything.

Is there any adapters that are made to lets say Hdmi to usb? I've seen one for hdmi to svideo. But most laptops don't have that either.

Are you just trying to use the laptop screen as a TV for the phone?

Yeah. Pointless I know I mean its a laptop. But my computer has hdmi inputs. Well the monitor does.

If your monitor has hdmi input then just plug in the hdmi cable into it.

so what you are saying is it shows nothing either on my phone or my laptop after connecting the HDMI cable ?
actually what I need to do is to run webtop on my computer.so i need to root the phone.before rooting i need to know all the things are working perfectly .
After rooting would it show those options in my phone and the laptop ?

@zeealot, you cant connect your phone to any laptop via hdmi... the hdmi port on your phone is for output so as the hdmi port on most laptops so therefore you cant connect output-to-output
if you want to display/output your phone on a bigger screen, you can only connect to a tv or an external monitor that has hdmi input port... also, rooting your phone doesnt have anything to do with it... I hope I explained that clearly to you

You could try using a HDMI capture device like this one:

but it is probably expensive.

$200 its professional grade used for way more then what your wanting it for. You can actually hook up your xbox or ps3 to your laptop with this and record the game play as your playing it.

Why don't you just buy the laptop and be done with it? You obviously have no clue about how HDMI works, and I wouldn't trust you trying to perform mods to your phone because I know you'll end up here whinging you bricked your phone.
Sigh.

you CAN NOT connect it to a laptop BUT if you're referring to an external display with hdmi input (monitor/tv) you can still use webtop without a dock... just search the forum for hdmi mirroring

Is there any way to make the HDMI output of the laptop to HDMI input ?like by using a converter ?

No. It's not possible. Period.
Use your TV, or get the lap dock, there is physically no way to make your laptop show the webtop off of your phone without an extra tuner card (hdmi are expensive, and not worth it).
Btw, google is your friend.

I think yhe2x had made it very clear already! Buy a new LapTop with HDMI "IN" port.

Even though I think dingdong a laptop with any form of input would be nearly impossible. Laptops just aren't something people expect, or use, as a secondary display.
Plain and simple... There is no way to connect your phone to the laptop and use webtop mode. TV, yes. HDMI computer monitor, yes. Laptop, no.

Hello all
Just bought one of these off the net for the missus so ill be active around these threads as well. Personally i have a xoom this will be like my second to flash the heck out of lol but as I've been reading about these i have a couple small questions
1. Is the sd card working on stock rom so i can flash customs or will an update to 3.1 be required like the xoom?
2. Does the usb port work as host out of the box?
3. Whats the general stable oc you guys are achieving?
I have tried to search these but some are hazy on the specs or they are outdated

Fastest claimed speed is 1.64ghz, stable closer to 1.5.
SD card does work on stock, actually is required for flashing. As yet you can't flash from on board only external.
USB seems to work for some devices not others depending on whether you use the full size USB or the mini. Look on the market for USB mount all, you do need fat32 not ntfs though
Anyone want to contradict any of this?

Cheers mate thats good to hear except for the host feature thats the whole point hoppwfulky i get a good one

Yes USB host [the fullsize USB not the mini] works out of the box. If your USB device requires power though - like some external HDD's - it may not work as there might not be enough power draw.
The mini USB is for the connection to your computer and SDK/ADB/general File transfer use - along side the Acer USB driver install [so make sure you've got the Acer USB driver installed on the computer(s) you plan on using to push files to the tab though mini-USB].

Yeh as i said im well advised due my xoom on rooting and android adb, drivers (not being a know it all smart azz) just those couple q got me thinking.. Thanks for a second opinion seems very similar to xoom. Shame how host cant produce 5v at 500ma it wouldnt be to hard for them to up the lousy 3.7v it seems they are running now

[GUIDE] USB Gaming on Nexus S

Greetings,
The purpose of this post/thread is to describe how to use a USB gaming controller on the Nexus S, which is now possible thanks to the work of fellow XDA member sztupy. Before proceeding, I highly recommend that you read his Galaxy S thread, especially the first few posts (http://forum.xda-developers.com/showthread.php?t=1450298).
First, some demonstrations:
Using USB Host Controller app and Super Mario 64
Batman: Arkham City
Metro 2033
Dirt 3
DISCLAIMER: I take no responsibility for any damage you do to your phone.
1.) FLASH KERNEL AND DOWNLOAD APP
First things first, you will need ICS and to flash a kernel that has USB OTG support in it. At the time of this posting, some kernels with USB OTG are:
-steve.garon’s kernel (http://forum.xda-developers.com/showthread.php?t=1427352)
-mathkid95’s Matr1x kernel (http://forum.xda-developers.com/showthread.php?t=1361477)
-Ezekeel's GLaDoS kernel (http://forum.xda-developers.com/showthread.php?t=1336529)
If you do not know how to flash a kernel, please Google it. You will also need to download sztupy’s app “USB Host Controller” (https://market.android.com/details?id=hu.sztupy.android.usbhostcontroller).
2.) ACQUIRE USB CONTROLLER
Next, you will need a supported USB controller. The following should work:
-wired Xbox 360 controller
-Logitech DualAction controller
-Logitech WingMan RumblePad
-wireless Xbox 360 controller WITH wireless receiver
-wired Sony Playstation 3 controller (not yet tested)
...probably many others
3.) OTG SET UP
Thirdly, you’ll need a working USB OTG set up. Sztupy’s thread shows you a few ways of accomplishing this. Below is a (crappy) diagram of MY current working set up.
http://dl.dropbox.com/u/15806590/diagram2.png
I think this is the best set up because you don't have to buy any fancy OTG cables or USB hubs. But that's just my opinion.
In terms of the order for connecting things, I find it works best if you connect the phone LAST.
4.) FINAL STEPS
Once everything is connected, open up the “USB Host Controller” app, select the “Settings” pane, and set the Operation Mode to “Auto-host” (if you are using a set up that involves an OTG connector/cable, then you'll likely need to select OTG mode instead). If everything went right, the app will close automatically and you should be able to navigate your phone with the controller. You are now ready to game!
Just a note with the 360 controller. The middle button will always flash on and off, and will not stay lit on one quarter of the circle as on an actual Xbox. AFAIK there's no way to fix this (unless you use tape heh).

Games/Apps TESTED & WORKING: (This list is not meant to be comprehensive, and will be occasionally updated)
Note: Pretty much any app/game that supports button remapping (such as emulators) should work
Emulators
-nes.emu
-SNES 9X EX
-N64oid (the right analog stick is not functional)
-Mame4droid
-FrodoC64USB
-Mupen64Plus AE
-FPse
Native/Regular Android Games
-Shadowgun
-Grand Theft Auto 3
-Samurai II: Vengeance
-Riptide GP
-Meganoid
-Reckless Getaway
-Cordy
-EVAC HD
-Radiant HD
-Muffin Knight
Some (not all) of the Xperia Play compatible games will work too. See here for a comprehensive list of Xperia Play titles: http://forum.xda-developers.com/showthread.php?t=1217060
Other
-OnLive (!!! This means you can play the majority of onlive games that are game pad compatible)

thanks man i was thinking of a way to do this.

This is amazing !

I tested the Logitech Dual Action controller yesterday, it works also fine.

Hi! May I use your first diagram in my post too?

Sure! Be my guest.

Cool! 10 chars

3 new gameplay videos added.

nice. any idea if this works with the controllers for the original Xbox? I have a modded Duke I use on the computer, just replaced the Xbox!usb male with a regular usb male, and would love to be able to use it on my Cappy. I know it works perfectly on the mainline Linux kernel, but I'm having no luck finding how the drivers were implemented in ICS. I can't test myself just yet, still waiting for the otg cable and download mode jig to come in.

I can't say for certain, but I think it should work. I found another thread here: http://www.acertabletforum.com/forum/acer-iconia-tab-accessories/1014-what-game-controllers-work.html for the Acer Iconia tablet, and one user claims their original xbox controller works.
I suppose the only way to know for sure is to try it out yourself. Once you get your OTG set up and running, let us know how that works out for you.

Nice thread, very useful for me, I sold my wired 360 controller, and i thought i will buy a new one when i asked at sztupy's thread if the 360 controller would work with this method, he mentioned me about this thread, and i saw on the 1st page that a wireless controller would work with the receiver...luckily i have one of those but on the op says only it was not tested...so could anyone give me some info about that?

Well the reason I suspect that it will work is because I saw this video www.youtube.com/watch?v=TrTmsZIb0a8&feature=related. Since we now have OTG it is reasonable to assume this would work for us as well.
I tried looking around for a wireless receiver to test but unfortunately all stores near my area only seem to sell it with the controller.

hm...i'm gonna try it, so, i didn't understand the diagram show in the OP (from the dropbox link, i'm not too good in this), but would it work, if i use a USB Hub, connect the hub to the phone, a usb charger to the hub, and also the receiver?

Read sztupy's post here for some ways you can connect a hub: http://forum.xda-developers.com/showpost.php?p=21503413&postcount=2. As you can see, it is indeed possible to power the controller/receiver from the hub if you have things connected properly.
When you're setting up USB OTG/host for the first time, use a simple device like a USB flash/thumb drive to verify that your connections and everything else are working properly. Then you can try hooking up other peripherals like the 360 wireless receiver.
To be honest, I haven't had much luck getting USB OTG/host to work with a hub, which is why I went and created my own 'Y' cable. It really isn't that difficult to make, and it's cheaper than using a hub, provided that you have soldering equipment already.

Word of caution, the 360 controller wireless adapter draws a lot of power, i recall there being high incidences of it dropping out when plugged into PCs, so be sure to power it adequately.

woah...i really don't know anything about this electronic thing how should i do?

Just look at your charger and check the output rating. It should say something like: 5.0 V, 0.75 A. Ideally you'll want the second number to be higher (like 1 A for example).
As a point of reference, my wired 360 controller works fine on 0.7 A. But as tiuk pointed out, the wireless receiver may be more demanding.
But really I think you should be okay if you stick with the standard Samsung Nexus S charger. If you need more current for your peripheral, you can simply disable the current draw of your phone with the USB Host Controller app. This way, all of the current from the charger will be directed to the device instead of being split between the device and your phone.

[Q] Ethernet to USB

Hey there,
I am pretty much a noob to all of this so please stay with me
I run a rooted Nexus10 with CM11 (20140603 currently) and need to use an ethernet to USB adapter via OTG. My OTG cable works fine using stick drives etc., but my tablet does not seem to recognize my adapter.
I tried using "ifconfig eth0" after first plugging everything into the OTG cable and then the cable into the Nexus - but to no avail.
I'd be very glad if any1 could help me out with this. I spent the last couple of hours reading through various threads throughout the internet, but was not able to find any solution :/
Best,
dersami
P.S.: Adapter: Königs CMP-NWUSB20

Does anyone have another idea? Im kind of in a bad spot right now, further research didn't quite help

Android only supports specific Ethernet chipsets out of the box (included drivers). So your adapter must be one of the supported ones or have drivers you can install which means you also need to be rooted. Search in the Nexus 10 accessories section to find numerous threads on Ethernet adapters. I have such a thread on my success with a gigabit Ethernet adapter with copious details.
