Here is a companion device for those already using the the Webtop hack.
http://forum.xda-developers.com/showthread.php?t=1199443
It's the same OTG USB hub hack used with the Atrix, just wanted to share my setup and testing. So far it works excellent.
Right now, I have a USB keyboard and mouse, a FAT32 flashdrive, and a FAT32 external HDD all hooked up the the hub, and I'm watching a movie
off the HDD.
The basic theory of operation is that in micro usb connectors there is a fifth pin, actually the 4th over in a schematic. That pin is actually the ID pin, when its state changes it indicates to the phone that it USB mode is changing. In our case, we ground it, telling the phone to go into host mode. Now because the phone cant supply power to the USB device, we have the red jumper wire on the hub itself. This is effectively bridging the +5 from the power supply to the phone.
It should be noted that as of this post, i have only tested FAT32 formatted drives with this setup.
I'm working with a friend at the moment on an NTFS module, so the Photon can utilize NTFS drives.
Now, my setup looks a bit off because my connectors are on order and the one in the pictures, is one I cut out of a motorola cable. So it doesn't look pretty, but works great.

Great job!
What type of usb hub can I use? does it have to have usb 2.0 or 3.1? Does it have to have ac adapter? Can I use a usb host cable otg instead of a micro usb and does it make a difference?
Thanks in advanced!

It can be any powered hub, if you plan to use an external HDD with it you should make sure the power supply for the hub is at least 2 amps. For now its only USB 2.0, USB 3 isnt compatible. I modified a stock USB micro cable, but you can but a OTG cable that will work with this setup. Like the link below, that is a OTG adapter. Also, the hub would need a few modifications, like i was talking about at the top.

Connected a phat32 hdd and mouse and keyboard non seem to work. My set up is usb to otg micro and judging from my soldering skills you can clearly see I added a white cable to jump from power to usb.

You may want to check your OTG cable. If its not set up properly it will not function. The un-used pin in the micro connector must be grounded. Ive noticed not all the cables you can buy are quite right. Thats why i build my own. I hope to get up rev 2 tomorrow...a bit more in depth. Maybe i can shed some more light on the issue...

Thanks for looking into this.
So, once you've mod a USB hub, are you using a cable that is <male micro USB to female USB A>?
I've not seen that before. Usually, USB cables that have a micro USB on one end will have a male USB A on the other, not a female. I did a quick search and couldn't really find any <male micro USB to female USB A> cables. I also didn't see any female A to female A cables that would allow for the same thing.
Please elaborate, thanks.
Edit: oh, maybe you use a USB 2.0 A to Micro B Female / Male Adaptor?
You need to buy some from amazon search micro usb to usb female. Or ever female usb to female usb they sell for $2 plus shipping. I bought otg cable didn't make a difference had to take it apart as well.

Just a heads up you need to connect your usb power adapter to the red usb from the hub then your otg and phone to the black and keyboard/mouse infra-red or 2.4 ghz stuff to the female usb adapters. Remember red goes to power!
I went back and forth trying to figure it out when all i had to do was push power to red. Duh!!

Ok, I was confused by what jguevara wrote. jguevara, could you tell me if I got this right?
1) Buy this OTG "cable" - it's really just a adapter:
http://www.dealextreme.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774
2) You might also want a hub for powering USB devices
http://www.dealextreme.com/p/cable-style-dual-power-1000ma-usb-2-0-4-port-hub-13526#open full view
The OTG adapter already does the "4th pin to ground" thing described by the OP, so using the adapter on the Photon makes the phone go into USB Host mode.
The phone, acting as host, won't have enough power via the USB port to power many USB devices, like portable hard drives. So that's why you need a powered USB hub. The hub in the link has an extra red USB connector. You can use the Motorola USB power adapter(the one that came with your phone) as a power source for the hub.
Also, I don't think this setup will charge your phone. It will charge devices connected to the other end of the USB HUB, but not your phone, correct? So, if you're using this setup to transfer files from one portable hard drive to another portable hard drive, with the phone acting as the USB host for the transfer, you'll be using up battery power the whole time it's transferring.
Do I have that right? jguevara?

Just wondering if a typical cell charger can provide enough power to power these three things. (or if it will even work properly)
1 The Phone
2 A USB flash drive
3 HML adapter
What I want to do is connect power to the USB splitter male (I already have a wall plug to USB female adapter) then with the USB female ends I will connect a USB flash drive and then use a male USB to male micro-USB cable to power the MHL adapter. The phone goes to the other micro-USB end of the MHL adapter.

I want this for two reasons. 1 So I can play media from a flash drive to a TV or monitor and 2 (if this will even work) use it to connect a USB to XLR cable so that I can record with a better quality microphone to my phone.
I realize that the phone being able to recognize and use the flash drive or microphone may be an issue but I can take a chance on that if nobody can confirm if it will or will not work.
BTW: if you have not already noticed, we are finally starting to get some reasonably priced MHL adapters on fleabay now. They are ranging from around 20-26 CAD (one in picture is 26)
I would like to know as well, as that sounds like a great alternative to carrying around DVD's and stuff, maybe even an externally powered harddrive, would need extfat or ntfs support though for large files.

Linux reads NTFS hard drives and flash drives fine, so I am hoping that Android should also.
I was planning on getting the MHL adapter regardless anyway, and the other cables that I would need would only be like 10 bucks. So I am wanting to try it out since, like you say, opens up more options for portability that may replace other devices or at least take up less space.
I was mainly looking to see if I would hear a show stopper of why not to do this, like if this set up could damage something that is connected.

You will need a proper usb to go cable to connect the flash drive or hdd, i have connected a flash drive to my phone without any problems..
I would think you would need a custom kernels or ntfs-3G modules for the kernel you are using.
The big thing is if the phone can deal with being charged, output hdmi and connect to a HDD over the same usb port at the same time?
Maybe a powered hub?
Also wondering if there would be enough bandwidth on the bus to support that all.
The big thing that would be good for me is that I could buy a cheap self powered hdd, load it up with movies and stuff and watch it while at work where there's a lot of down time, and being able to charge and use tv out at the same time would mean I could watch the iplayer or something on the tv without having to worry about battery life!
Hey, connect a mouse and keyboard as well and your phone is basically a normal computer!

Good idea. This powered hub is almost as cheap as the splitter cable and should take care of any power requirements.
As for the on-the-go cable, I have different angled micro male to usb female cables already so that I can help take stress off the jack when using it while charging. My USB flash drive does not power up with this cable. I just assumed it needed external power. What is different about the OTG cable, did they twist some wires or are mine just meant for charging if they are not working ? All the pins are present and the cable is thick, so no reason why they would not just connect everything internally.
Thanks for the replies so far.

In order for usb to go to work you need a special cable, its got a special pin that's grounded or floating or has a few different values depending, the cables are very cheap on eBay or there's guides on how to make them.
OTG won't work with generic cables im afraid.
I just want this idea to work myself :d

Im sitting here with a SGS2 with a USB kb, mouse, and a flash drive connected to it.
SGS2> (usb to go cable) > Powered hub > Mouse + keyboard + flash drive.
To get random devices to work (not hubs, input devices) you will need to add the device ids, see this thread for more info, more info and some device/vendor ids and a huge list of almost every device/vendor id
Attached is a rules file with logitech and some other vendors, add and expand as needed!
Now I need to buy a micro USB > many micro USB's and a mhl cable!
The powered hub is a must or stuff just wont work due to the power draw.
Im looking at picture of the MHL adaptor, and they all have a USB port for passthough, so we can defo at the very least charge while outputting via it.
The big question now is if you can daisy chain and do MHL and OTG at the same time!
Well, unless on a lucky chance the USB port will work with a splitter, you cant do MHL and OTG at the same time. A real shame
Thanks for the updates and links veyka. It also looks like the OTG cables do not charge the phone with the jumpered pins, so I will have to make sure and mark the OTG cables when they get here.
I should have the rest of my cables arrive in about 2-3 weeks and will post an update of what will or will not work. Sounds like the OTG cable alone should work with the USB to XLR cable for a microphone, as long as I can find a way to get the phone to recognize it. Though it would be nice to charge at the same time as well which the OTG does not support.
Do you know off hand what the headphone jack will accept for inputs ? Will it take TRRS or TRS audio in as well ? I am just looking at more options for XLR to the phone for connectivity without needing a mixer. Then I will use a mixer as well to see how much of a difference the balanced XLR out will make.

In the end android should support anything linux does, you might need to build a kernel module (driver) or find someone that will for you.
You can get pretty much any input device going with the links above, but other stuff, I dont know im afraid
Hope lives eternal.
No clue im afraid
No problem bud. You have been more than helpful already. I already have a plethora of cables and devices for recording on laptop and PC with Windows and Linux. My Android uses for recording are so far purely just for practicing so that I have it down in case something of interest is created. So ease of use and portability is the main factor.
It also interested me just to be able to find different ways of recording since so much of it is done through software these says. The more knowledgeable I am with cables, signals and processing, the more options that I will have available to me. Though I still like to mic an amp then process afterwards.
I'm assuming Razr support usb host functionality as the motorola multimedia dock has USB ports.
I connected a samsung micro usb male to usb A female cable to it with a USB key (checked with a pair of models), but couldn't reach its files.
The Razr couldn't see it.
Maybe I'm missing something as I'm new to android world, but USB host functionality right from the phone without too many adapters would be the first thing I would show to any Apple's slave to show what modern phone is expected to do.
Hope I wasn't wrong as USB host capability + Bluetooth 4.0 together with its fast response and good audio were the quite unique specs (at least on the same device) which lead me to invest on it!
Anyone found a solution to use a standard adaptor or are we tied to the motorola multimedia dock (or hopefully at least a smaller proprietary adaptor?)
Maybe something like the Xoom 'desktop hack' could be a solution or is there any simpler one? I don't know exactly if this hack gave also OTG functionality together with unblocking the desktop mode (couldn't understand from what I googled around).

I bought it in a real life store, actually 'Mondadori informatica' which had in stock Razr since the 10th of November.
If it helps it is Model: ET-R205UBEGSTD by Samsung.
I checked it with two FAT32 memory sticks and didn't worked
It's useless.
You need a powered USBHost cable, so you need to connect the 5V to an external battery or an external power supply, and TX/RX to the USB end of the device you are connecting to the phone.
Or, alternatvely, you need a powered USB Hub.
It won't just work. Motos don't give any output power from the USB.
so did anyone find working otg usb host so far?
i have the proper nokia cable which works on the Xoom but it wil not work on the RAZR (i assume) until like the Xoom a custom kernel can be installed to access this feature.
dont see that coming anytime soon (least not Verizon RAZR)

If OTG functionality were just a matter of powering a device with an external source that would not be a big issue considering the avaiability of power reserve devices.
I think a step forward in understanding Razr's OTG capabilities will be given dismantling a multimedia docking station and playing with it as soon as it will be available.

Oh, in BOTH, for enabling the Host Mode, pins 4 and 5 are shortcircuited, exactly as the USB OTG specifications.
Dismounted a micro usb male to USB female cable, to my surprise found it with connection 4 free.
Hence made the 4-5 bridge and checked again.
Yet no usb host connectivity with an external powered 2.5 HD.
The HD happened to charge the Razr.
Hence modified the cable disconnecting the +5V.
Now I should have an OTG cable with an external powered devices.
As soon as I'll find back my USB Y cable I'll check with it and some external devices to see if any of them is recognized right out of the box.
Yet I suspect that, like the Razr Upon USB connection let you choose between some differents kind of connections, maybe some settings has to trigger host mode.
Any idea?

What an incredible news!
There are quite a bunch of posts around about Razr USB host capability, but up to now (to my google capabilities) no one succeeded in connecting any external I/O!
I'm pretty sure about the wirings (at least according to pure guessing from your schematics) as I checked all of them with a tester.
The wiring I made is quite simple
on the micro USB side:
contacts 4 and 5 bridged
Data wires connected to its corresponding ones on the female USB.
Power and ground on the female USB taken from an male USB connected to a charger.
Anything wrong?
Now it comes the detail requests:
1) What does it happen when you connect your cable to the Razr. Does it recognize it in some way giving any notice?
2) Rooted is needed? (Mine is not yet rooted).
3) Any special setup/tweaking to have OTG working?
4) Where do you access the external I/O contenct? From a directory in \SDcard otherways where else? Can you name it?
5) What I/O have you succesfully connected? Any kind of memory stick works? Any kind of HD? Mouse? Keyboards?
Thanks in advance in the name of all of the Razr's users interested in usb host functionality!
You would have to connect ground from the charger to the phone also.

To bad it didn't work
No I have not tested. I proposed it because it have to be so electrically. If you don't connect ground the phone have no possibility to read the signal.
IE. if you power to things from different sources you should always connect the ground.
I don't have a cable so I can't test myself

The first try was with the Motorola LapDock, the second one with a custom USBOTG cable.
When you connect the RAZR to the USBOTG cable or to a LapDock, it says that a dock has been connected to the device (HD Multimedia Station or LapDock, both are recognized as docks, obviously).
So you have to connect something to your RAZR and it will be instantly recognized but the USB Device Connected notification is shown only in WebTop, not in Android.
The USBOTG cable HAS TO give power to the RAZR and to the devices you're connecting to it, otherwise the RAZR won't recognize the Dock Connected status.
Be sure your AC power is 5V with at least 1A, otherwise there won't be enough amperage for RAZR and the connected device and since the RAZR has got the priority, you'll only charge the device's battery and your connected USB device won't have the necessary power for working correctly.
ROOT is not needed for OTG USBHost operation as the device has been configured by Moto to work in USBHost Mode.
When you connect an external pendrive, the device will automatically create a device node and will automatically mount the connected pendrive/USBHDD in a directory created in /mnt.
I've successfully connected all the device I was able to use on ATRIX, including keyboards, mouses, an 8GB PenDrive and a 500GB external HDD.
I'm also about to see if I can do a modification to the ATRIX LapDock for including into it another USB HUB and a switchable (ON/OFF) 2.5 250GB SATA->USB HDD. If I'll success in this, I'll also post on xda-developers a thread with the instructions on how to do that.

MHL is not compatible with HDMI. Unless you have one of the 3 TVs on the market with built-in MHL, you need the box. blame Apple.

Works ok. Has standard sized micro usb connector, but fits View just fine.

mhl adapter seems like too much cabling
better to just get a cord that goes directly from the tablet to the hdmi slot

There is no such thing AFAIK.
All microUSB ports require MHL adapter for HDMI.
I'd be happy to learn that I am wrong on this issue.
I just got my MHL adapter from monoprice.com in the mail today and I have to say this setup is pretty nice. They have the adapter for $10 and you can also get the external battery that I have pictured here for another $13. It goes nicely with the adapter since it does need to be powered and of course is a nice extra micro usb charger to have when away from home.

The external battery is nice. I did plug it into my View to make sure it would work and it does, but I have yet to actually try to transfer all of the battery life over to the View. Given it is 2800 mAh it should charge the View to about 70% power. The main reason I got it was just so when you hook up the MHL adapter I wouldn't have to have another wire running out of it for a charger and I can also use it with my battery sucking 4g Droid Charge. I will say I watched 3movies yesterday before it died so it will power the MHL for around 5-6 hours.
I've got this one when it was selling for $13.75. Now he raised the price to$19.

It works, but WARNING:
it is listed as compatible for View. However, View power adapter doesn't fit. I had to buy a car adapter for View (well, I wanted it anyway), then use AC/DC converter and standard microUSB to USB cord.
I purchased the HTC M500 MHL HDMI ADAPTER today and it comes with 3 plugs. One for power and the second for the HDMI cable. The third is round like an ear phone plug but not marked. Anyone know what it is
Does anyone know of a compatible Micro USB AC power adapter to use with an MHL/HDMI adapter? I don't have any Micro USB power adapters around and need to order one. Does the voltage/current output matter for this?
hi,
i need a cable that outputs rca (red, white, yellow) to connect to the screen in my car.
is there such thing? is the cable for the incredible compatible?

Any USB power adapter will work . 5V @ 500ma minimum which is most.
You can power it from your PC with a micro USB cable also.

It has both HDMI out and analog audio, that is the small round jack, for headphones or devices that do not have an HDMI audio channel
I got this one from Amazon:
http://www.amazon.com/gp/product/B005NTHXYY
I figured I would just plug the USB power source into the TV for a source.
It is lame that this thing needs separate power....

not possible (without a lot of equiomnt)
RCA = analog
HDMI = digital
so you would have to use a converter

MHL was designed as a alternative to HDMI and USB. There are actually two TVs on the market that can take a direct MHL cable. LOL
The one I got works fine. Here is an HDMI to RCA converter:

is there a trick to make hdmi work. I have bought 2 adapters and both don't work. 1 was listed in this thread as working. Plug in to tv and nothing. Even when playing a video, nothing.
Hey, I was wondering if anyone knows how the Nexus Tablet 7 charges? Not through the USB port, right?
I have a Transformer right now w/ the dock & 2 full sized usb ports on it. But I have been waiting for the Nexus Tab for months, because of the screen, processor, and price. however since it does not have a microSD, I would definitely need to be able to plug in my 500GB usb hdd into it. I would need a OTG cable, right? And it does not use the MicroUSB port to charge, right? Otherwise how could you use the usb and charge it at the same time? Hoping someone can clear this up for me, thanks!

great, yeah, I would think you can do it but I just wanted to be sure before buying it. Perhaps when someone gets their Nexus Tab they can try it and tell us.
I'm not sure what the thoughts are around it, but I know Seagate has a portable Wifi Harddrive with an 8 hour battery.

I'm hoping that will deal with my additional storage capacity. I would love to know if it uses MicroUSB to charge just to avoid carrying several thousand adapters though.

after some digging i found out that the OTG cable or USB functionality does not work for external drives & only works for keyboard & mice by default.
im sure somthing has to be written to do this, or somthing has to be added to include the mass storage driver ?>

Spare charger puts out 5V 2000ma so yes it can charge via USB but much slower. The battery is so large most usb puts out 500ma so it would take 8 hours to charge battery from empty to full.

Hmm, well what I was asking if there was a way to charge AND use the usb port at the same time. Maybe with a powered hub, and a OTG cable? Anyway, would charging it via 5v 500 mAh be able to keep the battery level full? while using it, starting from fully charged?

okay, ugh.. I really hoped Google would just support usb host mode off the bat. I guess all that's needed would be a kernel with host mode supported. but you'd need CWM, and root for that.. are there any forums that have the Nexus Tablet 7 category yet?? I would like to stay tuned for updates.

You can always use USB hubs (not 100% sure). But, I'd recommend you to access your HDD over Wi-Fi. Many Wi-Fi routers support HDD connectivity. And, you can find HDDs with in-built Wi-Fi, too.

The tablet does support host mode.
However it can only be used for keyboard and mice, there is no drivers for external, or is sticks. Someone w ok und have to implement that with a Asop Rom

Here's the thing, I already got a Seagate 500gb 7200rpm drive, so I ain't interested in wifi drives. I was looking for confirmation that the kennel I linked world make it work.

Would that kind of cable work? The OTG cable I have for my tablet is just a mini USB (not micro!) to USB female, and it works fine. Would that kind of OTG cable work? So I can connect stuff like drives and keyboards.
Thanks!
From the picture it suggest to be a USB 3.0 connector to a USB 2 Connector, since USB 3.0 normally are all blue inside. It schould at least support USB 2 OTG if the USB A connector is missing the additional pins for USB 3 support as the color suggests.
FYI: To my knowledge OTG has the 5 th pin, not found in USB A and B and only are present in mini- and mircro- USB 2.0 connectors connected to ground to identify it as OTG. Thats all the difference to a normal USB mini./micro-cable. When I modified the connector from a mini-USB by connecting the 5th pin to ground and connected it to my Nexus 7 vie a mini- to micro-USB adpapter it didn't work because the adapter connect only the 4 standard pins, also found in USB A and B, through.

That's a USB 3.0 one. It looks like it has 5 pins on the USB part, but yeah.. I really don't know.
So what was the conclusion? That it only works with 5-pin OTG cables? And do you possible know if any of those I linked are 5-pins?
A mini USB 2.0 or 3.0 OTG will work. I have both and they both work fine.

Since it is advertised as USB 2.0 OTG it will most likely only support USB 2.0 transfer speed, despite that it uses what looks like a USB 3.0 micro connector. All USB 3.0 A connector that I own have blue isolation inside the metal frame, independent the color used on the cable or connector, which is either blue or black on my USB 3.0 cable. USB 3.0 A connector have an additional row of connectors removed in the back, that can't be seen unless you look directly in one.

I could not find how to activate it in the manual.
Some pages show/say you have to activate the USB 3.0 first,
it works only with windows pc and then
it works only for 10' before switching back to USB 2.0 speed.
However I could not find this option in the menu when I connect the Note 3 to my HP Elitebook win 7 USB 3.0 port. Can anyone point out where in the menu this should appear or if additional software is needed?
It does not detect USB 3.0 devices, e.g. like USB 128 GB PNY USB-stick.
This is stupid since it defeats the purpose of providing fast data transfer when you have The only benefit I have from USB 3.0 is that it is less likely that I try to force the USB 3.0 OTG 180° reversed, sind the noth helps.
PS.: My µUSB 3.0 OTG has 4 pins for USB 2.0 and 5 for USB 3.0 in the A female connector and 5 each in the two parts of the µUSB 3.0 male connector
