[Q] Desire HD USB OTG Host cable

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 ?

you will not be able to plug in a USB peripheral (mouse, keyboard) directly into the phone. it will not work.
you can, however, purchase a +5V powered USB hub (that plugs into the wall), and use that to plug into the phone and plug your KB/mouse into the hub, and it should work. you can find such hubs at www.dealextreme.com
to further answer your question, USB-___USB converters will work as long as the converters have all four lines hooked up. many converters are 'power-only' where only the power/ground lines are connected and the other two lines (data) are not.

So if i buy an ordinary pc hub that connects to power and the plug usb-to-microusb, it will work?

Well let it alone, ill buy a Bluetooth keyboard, will spare time and cables and converters ahahha

The Micro USB plug must be OTG (USB ON THE GO) or your phone won't recognize the peripheral. Also the advice given was correct, the phone USB port can't provide power to a peripheral device and so you must use a powered hub in between the phone and the peripheral device.
A USB OTG has pin 5 and pin 4 tied together in the Micro USB connector end to tell the phone to invoke OTG mode.

Lordareon: yea... if you'd go the wired route, you'd need a powered USB hub, since the Atrix's micro-USB port doesn't work as a host port. It doesn't provide power to external devices.

Samsung galaxy S3 OTG for USB 3. hard drives

Hi there,
I have a samsung galaxy S3 (rooted) and have recently purchased OTG cable. The problem is that when I connect s3 with Hitachi Touro (mobile USB 3.0) through OTG cable hard drive does appear in files. I have installed paragon NTFS and stickmount apps but it doesn't seem to connect even though a message keeps appearing "usb connector is connected". Hard drive gives a clicking sound when it is connected with S3 but works perfectly with the computer.
Does anyone know solution to this?
Thanks and regards

I've heard of some people having problems when connected to a usb 3.0 port on their computer and have to connect to a 2.0 port instead. Maybe related?

USB 3.0 I don't think is supported. What I've seen people do is use a 2.0 cable extension with their 3.0 device. As this downgrades it to 2.0 because they should be compatible with 2.0 just won't have the insane speeds as 3.0. Or you can get a USB hub and plug it in that way.

Sounds like the Hard Drive is not getting enough power (The clicking), do you have it plugged into an external power supply?

Thanks for all the replies. Hard drive is not connected to power supply as it is portable.

Splatdotsplat is correct. That clicking sound are the heads resetting to the park position. This usually happens when drives are not getting enough power. When the drive spins up it peaks its power consumption and cuts out because there is not enough so the heads reset. Portable or not that is the issue. I have seen this happen with some portable drives on computers (especially larger capacity). A lot of times the solution can be as simple as using a shorter cable. Sometimes it doesn't work.

as stated above, the only way to run external hdd's of any kind is to be sure they're powered, even some thumbdrives will draw more power than the phone can provide and you'll notice your batt life take a steep dive (as did my Galaxy Nexus w/otg on an HP 16gb thumbdrive)
power the drive through a powered hub and you're good to go!

This is why i recommended using a USB powered HUB as the HUB will give enough power to the external hard drive.

Having the same issue myself, otg cable with Samsung portable 500GB external HDD and stickmount pro works fine with my Nexus 7,but won't work with my Galaxy even though it recognises the HDD, so do you think a USB hub would be the solution, and can anyone recommend one
Thanks

Anyone?

Just to throw in some info. I do agree about the hdd not getting enough power as the cause for the clicking. I have a 500gb hitachi drive that does that if a long usb cable is used. The drive didn't come with a power adapter but instead came with a short usb cable that had two heads. allowing it to draw power from two ports. It also had a port for an adaptor though.
When testing with my Samsung Galaxy sIII It doesn't work unless I have the hd running via external power or have the second usb connector on the cable connected to a charging usb cable. Both options charge the phone while the hd is connected to the phone.
The usb cable with the double ports actually works well for me. I have the first port connected to the otg cable that I made and the second connection connected to a usb extender that is connected to my 2A tablet charger. That way I can charge at the same time.

Hi the problem i basically power as in the amount of current your device requires, i know that the standard specifications of the original 2.0 interface is about max 500mA and 5Vdc per port, in some cases the maximum output current is even smaller due to hardware restrictions, this can lead to difficulties when trying to power something like an external hard drive. Therefore a long cable will also give a problem due to the resistance of the material, because the required voltage level is not high enough.
I do not know if there is a spec sheet containing information about the output capabilities of the usb port, if there is one i recommend using that to match an external hard drives, if you do not want to use an external power supply.
Edit: you could also use an external power bank/battery pack but i seems a bit bulky

Sure go out and buy me one and i'll test all day..
USB OTG works out of the box for low power devices. I havent seen/read anything stating USB 3.0 works on the S3. I have a 1TB hard drive my brother gave me, its not the newer ones that are ssd so it has a power adapter with it and it works perfectly with my S3. Going to be using it in a few minutes to back up my internal SD.

So guys I have the GT-I9300 ( Galaxy S3 ) and I have 1 TB WD My Passport
I'm plannig to buy the OTG piece ! so as of now is possible to connect the hardrive to the phone or not yet !?

Is there even a driver and an app to do such a thing? As I see it the USB port is configured as an external storage device to connect to a computer not the other way around. What you are doing is connecting two storage devices together. There's no way I would ever connect anything to my phones USB port that requires power. If I were to, it would be through a powered hub.

I have read that you connected your S3 with external powered HDD. I bought yesterday the genuine samsung OTG cable and it is working only with memory stick and joystick controller. Don't know why it is not working with my external powered HDD - 500 GB WD. Any ideea ? My S3 is not rooted.
Thanks,
M.

No, nobody is going to have a recommendation for a powered USB hub.
It's a trivial, generic, piece of kit you buy nearly anywhere for under US$10 (unless you're a complete sucker.) Just make sure whatever you get *includes* a power supply.
Get one in the shape of a person, or a kitty cat, or a Tardis, whatever thrills you.

that's not quite accurate. when you plug your phone into your PC, the drivers that you installed will see your phone as a usb device (or media device) and allow you to use your phone as such
an OTG (on-the-go) cable allows you to connect a storage device to your phone, such as a thumb drive or external hard drive (powered or not) and then your phone acts like your PC and uses that device as storage

I can confirm that in my case forcing my ADATA HV610 1 TB disk to USB 2.0 mode worked. The trick is to use a standard micro-USB cable (e.g. the one that comes with your charger) instead of the standard cable that comes with the HDD.
More detail:
The common USB 3 cable which comes with most new HDDs uses USB 3.0 Micro-B plug which, in practice, is a micro-USB with a "half-micro-USB" next to it. The part most people don't know is that you can use a common micro-USB cable (as the one from your charger) to connect your HDD to your PC (or other device) with the cost of loss of USB 3.0 compatibility. Which, in our case, is what we need, as this switch makes the HDD less power-hungry.
Post a comment if it works for other hard drives too (I think WD also use Micro-B connectors for their USB 3.0 Passports)

[Q] Need some help with connectivity issues

Hi I recently bought the Samsung Galaxy S3 MHL/HDMI Adapter so that I can mirror my Galaxy Note II to TV.
HTML:
http://www.clove.co.uk/samsung-galaxy-s3-mhlhdmi-adaptor
Basically what I'm trying to do is to be able to connect simultaneously this adapter with my external HDD 500Gb.
HTML:
http://www.amazon.co.uk/Intenso-6021530-500GB-External-Drive/dp/B0056ZOLXQ/ref=sr_1_1?ie=UTF8&qid=1358358015&sr=8-1
That way I will be able to carry all my movies in the HDD and being able to play it through my mobile at TV.
Now when I connect the drive alone(non externally powered) to the mobile through USB OTG cable everything works fine.
That's the case when I connect the MHL adapter alone in the mobile. It works great.
My problem is when I try to connect BOTH the HDD and the adapter together. That way I can open my mobile navigate to my HDD and open the video file and play it at any given HDTV. But I can't find the right configuration to make it work. Now the first thing that comes into mind is a USB hub. I try to use this one I own with 3 slots I have but with no luck.
Code:
http://www.tomatoflash.com/products/product_detail.php?Cate=products&label=15&dSN=16&tSN=85&mSN=45#03
What I do is the following. I connect the HDD directly to the hub through usb. I use a usb to usb cable to power the hub. And on the third usb slot of the hub I power the MHL adapter. To the mobile goes the micro usb male cable of the MHL adapter.
Now what happens is that the MHL adapter as expected works fine, but the HDD, while it seems to power (green light on the HDD) cannot be recognized from the mobile.
I believe this happens for either 2 reasons.
First : There's no way the mobile can see the HDD through the hub this way (could an externally powered usb hub help I wonder??)
Second : I need to have a dual micro usb female to micro usb male cable (which doesn't exist??), so that I can directly connect both the HDD and the MHL adapter on the phone.
Below is a photo of the connectivity if it helps
HTML:
http://i50.tinypic.com/2myw2rl.jpg
So what do you think I'm doing wrong or what do you suggest in terms of connectivity?
Thanks in advance for your help and ask anything to clarify if I made things complicated
I'm sorry but I cannot post links because of my limited number of posts thus the "html"

[Q] looking for a OTG cable for my S3

Hello -
I have been looking all over for a cable that will work for what I am trying to do but I just can't find exactly what I need. Maybe I am looking for the wrong cable type?
I am trying to plug my Seagate Portable 4TB SS HDD. into my Rooted Galaxy Tab S3 SM-T820. I dont really understand what cable type
I need when I look at my Tab. I guess it is a Mini USB Type 3.0 - C ?? The only cable that I have that fits it is the one that came with the tab.
Am I looking for a Mini USB C 3.0 ( adapter to a ) Solid State USB 3.0 ? ? ? - Please look at the picture to see what type of connection my HDD has.
It is 2 connections in 1 . I assume part of the cable is for power and the other side of the cable is the transfer side. ?
So I guess my main question is: What cable do I need ?? ALSO ... If I cant hook up to the Portable SS HDD, then how about just hooking up my Tab to my 3.0 USB slot
on my desktop?
Thank you !!

You have three concerns here.
1. Power.
2. Cable.
3. Compatibility.
*If* the tablet can power the external drive, and the external drive is compatible, a usb c to micro usb 3.0 cable will be all you need.
If the tablet and the drive are compatible and the tablet can't provide enough power to he drive, you will need a powered hub...tablet connects to the hub, the hub connects to power and the external drive.
as far as compatibility, you are *probably* fine, as long as the drive is formatted FAT or FAT32. If it's NTFS or something besides EXT, you are most likely hosed.
Good Luck!

Buy Type C adapters that are designed for Mac books. they work great with Tab S3. Just make sure it is USB 3.0 or above.
