I just updated to 4.0.2 but USB devices (mouse) are not powering up when I plug them in and do nothing. I'm using a female to make USB cable I bought from Expansys.
Where they working for you before the update?
Hadn't tried it before the update since USB host was not officially supported.
Can anyone help with this?
I tested an optical Mouse und supprise it works. But a USB Memory Stick is still not accessible. Does somebody know how to get the stick running?

Are you sure you bought an OTG cable? A simple male to female adapter wont work because it is missing the grounded ID pin on the phones (=host) side. Without that pin the phone won't know it has to act as host and power the attached device.
I the USB Host cable from a SGS2. This seems to work, because the optical mouse works fine.
I'm just waiting for the drivers to connect Memory sticks or HDDs.

I bought this cable when I ordered my Nexus form expansys, it doesn't mention if it's OTG or not but it was cheap so I figured why not..
So if my Nexus cannot provide power to connected peripherals does this mean my cable us not OTG?
I have an OEM OTG from Motorola I use for my Xoom and Nikon D7K and it does not work on the Galaxy Nexus, I am on 4.01 on the Nexus

If I didn't remember properly, CA-157 has a Micro usb A connector. S2 is using USB B
iirc the CA-157 USB OTG cable has a microUSB A connector while the GSII has a microUSB B port. Won't work unless you trim the corners.
Just get the $2 for 2 USB OTG adaptors w/ free shipping from dealextreme.
i see... thanks all for replying!
I have on that works perfect on sgs2, reads sd cards/thumb drives/ and can use wireless mouse, and someone said they used a keyboard.

I have the Nokia cable that comes with Nokia E7 and i can assure it DOES NOT work!
the shape of the port itself is different and it won't fit into the galaxy s2 port.
Different Types...
There are two different types of nokia cable. One for the N900 or N810 and the other for others (known as CA-157) the only way to get a working cable for the SGS2 that is supposedly for Nokia is an unofficial (ebay...) micro-usb b so basically the N900 and N810 and a few others. Unfortunately Nokia have modified the ports slightly on their phones so they support the official Nokia cables (that only work on Nokia phones) and the unofficial MicroUsb Gender-X (depending on what the phone is.
This rules out all official Nokia cables and all Cables designed for Micro USB A Phones.
I got some MicroUSB OTG adapters from dealextreme and they work fine. Tested them with my 16GB thumbdrive and my Logitech unified mouse & keyboard dongle. Funny having a mouse cursor on my SGSII.

Can you please share what kernel / ROM you guys are using? I got an adapter which works great with USB memory and wired USB mice, however, my wireless mouse does not show up and hooking up a wired keyboard hangs the phone hard and I have to pull the battery.
I tried Sensation by Crysis 1.9 (kernel is SpeedMod) and WanamLite 5.7 (kernel is Siyah 2.1) same results on both. Planning to try MadMack 2.2 tonight as its closest to stock. If the adapter was bad, it should not have worked with memory or wired mouse either.
Will appreciate any pointers in this regard.
EDIT:
I also tried CF-Root kernel as it is nearly stock, checked lsusb and dmesg outputs, lsusb is always correct but dmesg show kernel logs which are problematic. My wireless mouse is detected as keyboard (wrong), another wireless keyboard / mouse combo is detected as composite device (correct) but get error -104 while activating, wired keyboard gets detected but crashes something in the kernel, I also used 51-android.rules but not sure if it helps because /etc/udev did not even existed and I had to create it.
<4>[ 68.820948] generic-usb: probe of 0003:09DA:054F.0002 failed with error -104
Now as all of these devices work perfectly on my Iconia on Honeycomb I guess an ICS upgrade for S2 should bring similar results, so can only use mass storage till then

Hey there, i have tried gathering information about this subject and it seems all threads always lead to this announcement:
http://www.gottabemobile.com/2012/06/29/galaxy-s-iii-new-mhl-connector-also-enables-usb-on-go/
Short: Samsung have changed to an 11 Pin-out to enable USB OTG and MHL Hdmi out at the same time. I purchased an original HDTV Adapter (EPL-3FHUBEGSTD) which as far as i can reliably count indeed has about 11 connectors inside the USB connector that goes into the phone.
Now, i can get HDMI out just fine, but ONLY when i also connect the MHL adapter to a power source (a PC USB Port will do fine), however i have also read, that the phone is able to power the MHL adapter itself but obviously would not be charged then (no surprises there). This does not work however.
Further, connecting a USB OTG cable to the micro usb port on the MHL adapter does nothing. No notification and no devices connecting. No power either, since the LED on my USB Hub does not light up as it should. Connecting any devices to the hub does nothing to change that situation. If i leave out the MHL adapter and connect the USB OTG cable directly to the phone, everything works perfectly. I have tried this with 2 different OTG cables so they are not the problem.
This is an original genuine HDTV Adapter for our phones, which according to that post should be working fine with USB OTG.
AFAIK, this topic --does-- come up more frequently now as i can find a few more discussions about it, albeit none really helpful:

That wiki entry is the most interesting link as it definitely states that using MHL and USB OTG simultaneously is possible and is also the reason why the 5 pin layout was changed to an 11 Pin layout.
Looking forward to reading your replies!

I don't see why you would feel the need to ridicule me for bringing up this thread. it's not wishful thinking, seeing as even the wikipedia entry on MHL clearly states it should be possible. There is also a blog entry on the exact same topic and even the movement to boycott samsung accessories have stopped because of this: http://www.galaxymhl.com/
I don't really understand why people aren't looking into this more.
I'm not ridiculing you. I want the same thing. What I said was my legitimate wish list. I haven't bought the mhl adapter because I'm holding out for an all in one solution. I'm still waiting on Samsung to give us a product that does mhl and otg simultaneously.

I'm sorry, i must have gotten that wrong. I find it very confusing Samsung do no release enough information on this in order to make it work. Neither the phone documentation, nor the official 11-Pin HDTV Adapter manual mention this in any way.
I'm waiting also for a dock with MHL+USB OTG at the same time by Samsung, I dont understand why the official MHL adapter does not support this already but I've been searching and I have not found yet any example of both working together. It clearly seems that the MHL 11 pins cable we can buy right now does not support this since nobody has tested it succesfully but what I don't know is if that is related to Hardware or it also has something to do with software. I read a couple of weeks ago that Google was thinking about using the phone as a PC via docking, I think the idea comes from Motorola? So maybe the availability of both connections at the same time is also related with android, who knows, maybe in JB it will be possible...Has somebody tested MHL+USB OTG in JB with the official adapter?

As soon as i get home, i will try flashing this rom: http://forum.xda-developers.com/showthread.php?t=1695562
It comes with the latest stock kernel and appearently won't boot with anything else so Samsung must have made some changes to it. In a few hours time I'll be back with information on how that worked out.
I can confirm it NOT working on Jelly Bean. The MHL adapter does provide video HDMI output, but only as long as it is plugged into an external power source. When connecting an OTG usb cable, there is no reaction at all. There has to be some way of getting the phone to power the HDMI adapter. Do any of you folks have a good link to a kernel dev who can have a look into this? There has to be a MHL modul for the USB driver. Ghokanmoral probably has more insight into this...
Summary: USB OTG and MHL work fine separately, but not simultanously on JB using a standard genuine Samsung EPL-3FHUBEGSTD adaptor.

The final result of this is that USB OTG work with the Samsung dock, but not otherwise...and that is why they changed the pins to 11. For the dock to allow for OTG at the same time as HDMI out. Does everyone agree?

I don't really know how this is accomplished with the dock, but if it works with the dock, I have to think that the same technique could be used to make it work with other adapters, too. If it's a matter of putting a voltage or a resistance across two pins, that would not be a big deal to do.
It was figured out in the thread that this was split off of.
we already found the resistor value to do it, the wiring.. everything.
Anyone try...
Anyone try a usb Y cable which will inject power over a USB and still allow for a separate device to be attached? I would post a link but i'm noob here. You can find it as "UTStarcom USB Adapter Y Cable"
The HDMI part of the split HAS to be powered...but the USB OTG does not. So...if there was such thing as an 11 pin micro usb Y splitter, then the OTG side would work while the powered MHL adapter was on. Essentially this is what the dock does.
Is it possible to create an 11 pin Y splitter? Someone needs to get one of those docks and tear it apart to see how the leads are split...lol

You won't be able to charge the nexus that way - you'd need a custom kernel for that (there's one for original nexus 7).
I'm planning on doing something similar, I'm wonder if a powered USB hub would at least power your USB accessories (I'm going to plug in a DAC and Hard drive).

I understand I'd lose ability to charge the nexus 7 using USB OTG (OTG limitation) but I can live with that.
Thanks for any results

AFAIK the Slimport cable needs to be directly plugged into the USB port so it can switch the Nexus 4 from standard microUSB to Slimport broadcast mode on negotiating with the hardware. If you attempted to run the Slimport adaptor through a hub or Y-cable it wouldn't work.
Thanks,

Yeah, the microUSB port on the Slimport is for power only, the data pins aren't even wired up.
Suppose I connect Nexus 7 to a monitor through SlimPort. This monitor has USB ports built in. If I connect a keyboard or mouse to this USB port, will it work with the tablet?

No - this wont work.
As stated above the data pins on the slimport are not connected so the USB can't be used for anything other than power.
ie. Tablet can't do anything else over usb when the slimport is in use.
Bluetooth keyboard + mouse could work for you though

Thanks. My intention was to use the tablet as a PC alternative for my parents. I have dropped the idea. Now I am thinking about getting one of those Android mini PCs instead (thread here).
The issue is the limited number of pins on the Micro USB port are multi-purpose.
A Micro USB port has 5 pins, one is power and another is ground, that leaves 3 for data. These 3 "flip" (for want of a better word) between USB mode and Slimport mode, So it can only do one or the other at any time.
So the lack of data pins on the slimport pass-through port (as stated above) is not the issue. They didn't bother wiring them up because they share a couple of pins in common and so wouldn't work anyway.
[Edit]
Just to clarify a slimport Micro USB connector has 5 pins. Samsung on the other hand are now using MHL 3.0 and they are pushing on with an 11 pin connectors that open up all sorts of options such as simultaneous data connections and even multiple displays! nice!
