Hi,
I've been wanting to hook up my desire hd to usb hosting and have not been able to find a cable for it.
I was wondering would it be ok if i connected a micro usb (male) to usb b (printer version) (female) adapter
to a,
standard printer cable with usb female at the end?
This would result in one end being a micro usb male and the other end a female usb
I look forward to your answers
Thanks alot for reading
That probably wont work.
I in fact saw an article yesterday, but can't recall the link. (Will look now).
IIRC, you need to modify the USB cable somewhat to get the DHD's USB port to detect an OTG connection.
Edit:
Here we go: http://gigaom.com/mobile/how-to-add-a-usb-keyboard-to-an-android-phone/
I think if the software supports usb host mode, with a 'micro usb type a' to 'usb type b' cable you can connect to a usb device. That is if the DHD is equiped with 'micro usb type ab' receptacle.
oh wow, ok thanks ever so much!!,
however, i just need to confirm what three cables you need so i can go out and buy them, i need:
Car charging cable (which one is this?)
Micro-usb cable (is this with the microusb male on one end and a standard usb male on the other end?)
USB extender cable (is this with one usb male and usb female on the other end?)
thanks

I have no idea really, but if you are successful, let us know
I'm just having trouble understanding what cables are needed.
On the website you gave me, it says i need:
a car charging cable, a micro USB cable and a USB extender cable.
Is this effectively two micro usb cables and a USB extender cable?
or does one HAVE to come from a car charging kit?
please help!!
thanks

Nice find! I did see the mini one only
Gonna order and try it out. No great financial loss if it does not work.
Obviously we will need a USB Host module for the kernel if not already present. Will check tonite.
i've finally made my host cable!!!
i now need micro-usb dongle host module. Is this where you have to get hold of a car charger and get the end of it and unsolder bits?
The USB Host module is software. It is loaded by the Linux kernel.
ok well i need to get that too.
Also, whats the bit with the car charging cable? what that for?
I'd be really interested in this as well. Would be awesome if i could just connect a usb drive or my camera to my phone to copy data.
So does anyone know if a host driver is available for the desire hd.
I really have no idea how it would work, but it should, as loads of tablets are able to use 3G-Sticks to connect.
Today I recieve my USB Host adapter cable for the DHD.
When I plug it into the DHD and connect a USB Hub the car panle ("Auto Bedienfeld") starts.
Connecting a USB Keyboard to the USB Hub doesn't show any impact. But this is what I have expected. Next I try to integrate the patch from sonic74 to a kernel for the DHD.
http://sven.killig.de/android/N1/2.2/usb_host/
At the moment I use Android Revolution HD 2.0.9
Any progress?
I really like the USB host future on my Desire HD,
I want to connect my USB Drive to my DHD if this is possible? So i have 16GB More storage if needed ;D
I've ordered the converter thing from dealextreme, someone that could make a flashable zip to enable usb host functions?
Was also quite interested on this.
My wish is to connect my dSLR to the phone, and move all jpgs/nefs from there to a internal card. Or copy, and use the device for better visualisation.
As the camera has its internal battery, power shouldn't be a issue. It would be awesome
I am still working on this.
At the moment it is working for a short time, but then there a same errores.
This meens it should be possible, but same more research must be done.
My Kernel is based on the BUZZ 1.3.7 Kernel, and following patches:

Quick Q: What did you connect? Or you didn't connect anything ?
The most Micro USB to USB converters are not work if you want to use it for OTG converter, because the 4. pin of the micro usb plug is not connected!
The most ebay and computer shop's converters like this!
If you want to use it for working OTG adapter you have to connect the micro usb connector 4. pin to GND (5. pin).
Like this:
I made this mod on my adapter and it works!
First you have to open up the outter cover and carve the plastic around the micro usb pins. You can use multimeter to check the pinout.
After that solder the 4. pin to 5. pin with a piece of wire.
And finally glue back the outter cover.
Video:
So if you have not working adapter you can mod it, if you have suffice experience with electronic and proper tools.
Only do with your own risk!
I have this Usb converter!
With your mod works perfectly!!
just tried it it works perf, thank you!
Weird I got one off eBay from Hong Kong and it works without Modding. Can open files off a USB stick. Got it for £1

I buy a pair in Dealextreme.com
SKU 50774 o search OTG
It may have a resistor between pin 4 and 5, kind of like a jig,
I remember there was a fun with resistors thread for the sgs1.
I may attack tge free dock I,got from optus.

OTG Cable USB (B) to Micro USB (A) Powered with AAA batteries ?
As one knows, Samsung has promised a MHL Cable
You noticed it is not only a cable but a box out of which you may plug in an extra power supply.
The obvious reason is if the passive monitor does not furnish 5V, the phone will rapidly be out of power.
Now you know that to obtain video rather than anything less, Pin 4 (sense) and 5 (Ground) of micro USB (male A) must be connected with a 365K resistance.
I suppose the dock Samsung is selling for I9100 (yes, I have it) is grounded at 1000K as it provides audio with remote, and yes, the dock provides power supply via extra micro USB as well.
I come to my point: If I want to access any USB data On the Go, I need a cable OTG with 2 ports: USB 2.0/3.0 (female, B sided) to a micro USB (male, A sided, grounded but with no resistance = 0K). Many of them exist on the market out there.
But it is quite impossible to use because of lack of power supply in the passive device (let’s say a handy 1T HDD usually powered via Host connexion !
Would it be possible to insert some sort of receptacle for AAA battery in the middle of such a cable to provide for power while you are for a long time out of access to an electric plug ? Does such a cable exist somewhere to buy ? What would be the sheme to mount this ? HELP !
Is it possible to add USB charging cable to USB-host cable? I want to use mouse\keyboard\flash and charge device in the same time.
I also interested how to add power to USB-host cable for devices "High-power device connected".
OTG and Power
thats excactly my question:
is it possible to use otg cable with a trackball or mouse and at same time charge the S2?
give power to usb mouse and charge S2 over a charger!?
Is it possible to use a game controller over usb otg? Would be pretty nice.
Wanna have a S2Play ;-)

i do have same problem..is there any suggestions to make sgs2 can read the high-power USB flashdisk via otg??
An USB hub with external power maybe ? I didn't tried this kind of setup, but it should work. I have a hub, but I don't have a OTG cable yet.

I've been try this, but still doesn't work for me..I'm also used electrical multi-tester, and the usb flash already has 5V voltage but in my sgs2 still nothing happen (my usb flashdisk doesn't mounted to sgs2)..
Is there any driver/apps do I need to install first before using OTG?? or, is there two kind of sgs2, the one which support OTG and the other one not??
please someone help me...One point I choose this SGS2 is the OTG feature..
PS: sorry for my english
Sorry fr startng a new thread, wen so many threads r available showing video proofs of working OTG cable.......bt i reliazed, tht making a own OTG cable s much simpler n can be done without ne cutting or soldering
First d basics -
1. Generic USB cable (For data transfer or charging) is different from OTG cable - IN OTG cable, Pin 4 is shorted wth Pin 5........in essence, Galaxy S 2 is able to differentiate between USB OTG cable thru this pin.....
2. For converting any generic cable to OTG cable, u just need to short Pin 4 with Pin 5 and it will work like a charm.....
3. I have done this using Motorola Micro male to Mini female adaptor - theoretically, u can do this by using any cable which has 5 wires/pins coming from micro plug - cable supplied with samsung shud also be able to do this
4. U can simply test self made OTG wire - on connecting it wth phone, it should show "USB host connected" in status bar even without connecting any flash/pen drive
Now details -
Pin usage - normal Micro B plug (used in galaxy S 2) - uses Pin 1,2,3 and 5 for data/charging. U need to cut open the wire just where micro plug is connected and short pin4 to pin5. Alternatively, u can use an adaptor (like Micro to Mini) and try shorting the wires at outlet. I have done using stapler pin. Its easy and saves u trouble of opening/cutting or soldering any wire. Hope the pics r clear
Male Plug -

\ _ _ _ /
I have then attached Micro male-mini female (shorted) adaptor to Mini USB-USB 2.0 and then to female USB-female USB adaptor and finally to Pen drive
I will try to attach a video proof, in case sumone needs it. For indian users, u can get hold of Motorola Micro male to mini female adaptor @ Heera panna in mumbai or Gaffar market in delhi for Rs 150
P.S. - Shorting Pin 4 to Pin 5 to enable OTG mode is not my discovery and i understood it going thru multiple searches and posts on XDA and other sites. Sorry for not linking to those posts
Thats just a nice idea because you don't need to cut or damage one of the adapters.
And a good solution till the original USB OTG cable is in stock.
Thanks.

Excellent works perfect !!! Thank you very much!
Sorry for being noobish, but could anyone explain the difference between OTG and generic? Thanks!
Do ALL SG2's come OTG host enabled??? cause I tried this and doesn't work for some reason.... I've opened up a micro-usb connecter all the way to the plug and soldered 4 and 5 together...still nothing (tried the staple method first ofcourse but I saw that black and the xtra cable were actually internally already connected)

Basic difference between Generic n OTG cable s pin lay out....
Generic helps u connect s2 as slave to PC/laptop n OTG cable helps u connect other USB drives to S2, thus making it a master....Hope it clarifies ur doubt

Tried stock AND custom.....nada...
I'll try making another one.
update: still no luck, bought 4 different ones on ebay AND build one myself but no success. Even flashed back stock 2.3.4 rom...
Any other suggestions??
although some weeks have passed since you posted your question, here's the answer: amazon.com/gp/product/B004ULZD7U/ref=oh_o00_s00_i00_details
works perfectly for my galaxy s2 as well as the huawei media pad. it's even possible to load the slave device by the master. (both ways)
USB OTG Cable even cheap
Hi,
I bought this USB OTG (On The Go) cable online at eBay.in for Rs.115.
I tested this cable with Nokia N8 works fine which is even cheaper instead of making from another cable.
i got a usb otg cable at faizul communications, jagdish market hyderabad,
price - 100 rs.
works with sgs2, and all accessories including pen drives and mouse/keyboard and even game pads
Regarding usb otg

First decide which functionalities u want in the hub...
1. MHL - For HDMI connector ??
2. USB OTG ??
3. Normal USB - Charging and Data ??
I understand that new MHL adaptors (S3,S4) are 11 PIN and thus only 2 of the above 3 can be used simultaneously (MHL-HDMI with Normal USB OR MHL-HDMI with USB OTG)...
U will have to search for the Pin lay out of your phone and whether it supports MHL-HDMI output or not and then can work towards it :good:
sorry wrong thread...
Hello,
i would by a USB OTG cable to test this function! Is there something spezial to note about the cable! I have searched a cable where have Micro B to USB A female and found it here! But don´t know if a OTG cable need spezial power supply!
Thx for Help!

Can someone upload photo for his usb cable from inside, because I think there is problem with my usb cable
Blimey, get a new one, they are not expensive. Any micro usb cable will do.
This mean any micro usb will work well not special one ! Right
Yep , I use whatever I have to hand. HTC, Samsung, official. It's just a standard micro usb to usb cable.
