I recently got an MHL HDMI adapter and realize there's a bad contact in my usb port, when I move the wire, the HDMI keeps getting connected/disconnected. As I understand, there's more pins than a normal usb plug in a S3 to support HDMI. I wonder if replacing the USB port would fix my HDMI problem or if it would most likely get it worst ?
Thank,
Kris

Is it a third party one? (Non Samsung mhl cable) I have this problem with a 3rd party one but just pull out wire out phone then plug it back in

I just found a MHL cable for the SGS2 on Amazon with Micro-USB to HDMI.
I have a Samsung HDTV bought about a year ago. Now i know that MHL means you can charge as well as view the phone stuff on the screen but MHL TVs have not released yet (i think, and even if they have i wont be getting one anytime soon).
So my question is can i still see the TV out if i use the MHL cable on my older TV? I know it definitely wont charge.
Anyone?? :S
yes you can.
all you need is the adapter from MHL (micro-USB) to HDMI, connect the HDMI to the TV and you are good to go.
the advantage of the original samsung adapter is the ability to connect a power cable to the adaptor and charge the phone while it transmits the picture to the TV.
hope i helped
Thanks mate
For anyone confused, an MHL cable is a Micro USB to HDMI cable - no ifs, no buts, this will transmit HDMI from a compatible MHL port. Nothing else needed (except I believe it must also be connected to power)
Your micro USB port on the bottom of your SGS2 is an MHL/USB port, and will therefore work.
Important to note is that not all micro USB ports are also MHL ports, therefore will not necessarily work on some other micro USB port on a different phone.
Hi together,
ive asked me if it is possible to use an adapter for 1x micro usb (plug) -> 2x micro usb (jack).
Could the phone handle 2 USB devices at the same time?
Maybe then it is possible to use the HDMI output and the USB host parallel?
For example to use an TV as screen and an HDD as the source for a movie.
This would be nice.
Thanks in advance.

When the connector is used for HDMI I doubt it can be used as USB at the same time, I'n sorry.
Maybe in a few months cyanogenmod provides a hack, if there will be an dual adapter soon.
We will see. Thank you.

The hardware needs to allow this if it'd become possible. You need a really smart USB dongle that knows how to split the HDMI output from the USB output.
Sounds a little too difficult to ever happen.
Hmm thats right. I think i still dream xD
But thank you.

it is not possible. because as stated on this forum many times before, the type of usb connection is determined by the resistor between pin 4 and 5 of the micro usb connector. the strength can tell the phone, that there is either a charger, a pc connection, car kit, jig, usb otg or mhl connection present.
and i believe, this is an important thing to keep in mind for so many things:
for instance, why the original car kit triggers car mode and generic car charging cables don't or why not just any micro usb male to usb a female will work as a otg cable or why flashing should be done with the original usb cable...
so if you were to buy or build a micro usb hub, since it has no resistor in the very plug that connects to the phone, it cannot be used for anything but charging and quite frankly, i wouldn't connect more than one charger to the phone.
however, if you want to use your phone for presentations or watching movies and still be able to use it, get a bluetooth keyboard and mouse or a bluetooth presenter or do it the other way around and use a usb input device and transfer your media using allshare. everything else is physically impossible, so neither CM nor XDA can do anything about it. the only device that can do what you want is the new motorola. it has a separate micro usb and micro hdmi port and a docking station, so you can use it as a full notebook.
Thats obvious. Thank you.

has anyone tried using an mhl adapter for hdmi out from the jetstream? what about usb on-the-go?

I have a MHL for my samsung infuse, maybe i will give it a shot later... I am assuming there is some sort of support as the jetstream has a modified microusb connector. It can support a regular microusb cable but it also takes a cable with an extra 5th pin for something... must be some sort of other dock or cables coming out for it.
MHL does work. I used the "universal" MHL adapter that T-Mobile US stores sell and it worked once I plugged in a 1 amp phone charger. MHL adapters require micro USB power in, and I found that less than an amp didn't work. But the HTC Sensation and LG Thrill chargers did the trick. I have a video of it in action in our Jetstream review:
http://www.mobiletechreview.com/tablets/HTC-Jetstream.htm
The device lists USB external storage under the storage applet. But I had no luck using a USB OTG cable (the Motorola Xoom optional cable). It didn't see flash drives, mice or keyboards. I've asked HTC PR about USB host, but it's taking a long time for them to get me an answer.
btw... the MHL adapter that came with my Samsung Infuse also worked with the Jetstream as long as i had the charger plugged into the MHL adapter, couldn't power itself on its own.

I want to have S2 with usb keyboard, mouse, (probably a pendrive/hdd also), and a hdmi screen connected while charging the battery. My question is, what cables/adapter and usb hubs would I need to achieve the desired configuration?
As far as I know, what you want isn't possible. The MHL/HDMI and USB are mutually exclusive -- they share a connector, and when the MHL/HDMI adapter is plugged in, the connector switches into MHL mode, and the USB data pins are re-purposed.
you can't, maybe a bluetooth mouse/keyboard will solve part of the problem. And maybe you can use a powered hub to use them together, but not with HDMI
The phone differentiate MHL, USB,USB jig, and charging mode (AC vs dc) via resistance between two of the connector pins on the cable. So one mode at a time.

Has anyone made an OTG cable for the TFP? I don't like the chunky USB OTG connector and thought an OTG cable would be much better.
Not quite sure what you mean.
The only proper usb connector is a standard type A connector located on the keyboard, it has insufficient pins to implement OTG. The only other usb connectors are the propriety asus ones, one on the tablet and one on the keyboard, the other small connector on the tablet is HDMI output
I have the "chunky" USB OTG connector as well.. I don't think there's a cable though... I looked everywhere on the net
I don't have a dock therefore the only way I can plug a USB flash drive, Keyboard/mouse into the TFT is via the ASUS USB OTG Host adapter View attachment 1384503
I was after something a little slimmer and believe a OTG cable would be ideal - Refer to picture for an example of what I'm referring to View attachment 1384504
Micro USB OTG cables can be used with many phones and tablets sporting a micro USB connector. The TFP obviously doesn't have a micro USB connector therefore I was hoping someone knew how to make an ASUS 40 pin to female Type-A plug which replicates the ASUS USB OTG Host adapter.
Has anyone pulled apart the ASUS USB OTG host apapter? What's inside it?
Hey guys. There are several articles and videos around on how to make your own OTG cable. It essentially involves shorting a single pin. I have no idea if it'll work with a TFP, but I'm going to give it a shot today or tomorrow if I get some time. My plan is to use the normal TFP USB cable, but plug it into a female/female USB gender changer that has been modified to short the pin. I'm almost positive that it'll work on my SGS3, and I don't see why it wouldn't also work for my TFP. I'll report back.
Nevermind. I now see that the TFP USB end has five pins, so they won't match up with the 4-pin female USB port. Oh well...
TFP and OTG
Does anyone know if the OTG will support a USB hub?

The TFP doesn't have OTG, it's a regular USB host.
So yea, it will support a hub because it's a standard USB device class, with its driver already part of the kernel.
