Hi all
Is there any mechanism that you can use to allow the XDA 2 to connect to an external USB hard drive?
I know some of the new PDA devices will have USB Host controller interfaces built into them, but isn't there ANY WAY that we can achieve this with the XDA 2?
Thanks in advance
Akhtar
There is a Compact Flash to USB adapter available.
So if you had the XDA II BackPack accessory you could use that CF - USB adapter to connect to a USB Hard disk.
This isn't the one I have seen but is similar. Unfortunately though this one is only available on pre order http://www.expansys.com/product.asp?code=113389
The one I saw had a short cable with single male USB socket and was working in a HP iPAQ.

Looking to find an adapter that will allow me to browse a jump/usb flash drive on my Kaiser. Have seen several 3 in 1's online, but none seemed to have a standard usb port and have also seen adapters that go from standard usb to mini but not the otherway.
Please let me know if what I am looking for just won't work (ie the Kaiser can't use an attached jump drive).
Thanks,
Zack
There is no way you can browse a flash drive with your kaiser (maybe using a redfly device) but the kaiser is not able to work as a usb host device.
I was afraid of that, but wasn't sure since it can use SD cards. Guess I need to do some reading to learn the difference between a USB drive and an SD card.
Thanks again for the informative reply!
Cheers.
Hi,
I made my own usb otg adapter from a plain usb a to micro b adapter. You have to connect pin 4 /which is not connected/ to ground to fire up host mode.
Edit: It is not easy to dismantle a usb connector or adapter and it requires soldering. So I guess anybody with the necessary skills will find the pin on his own. I will not post photos because my solution is far from being pretty.
For everybody else: the nokia USB OTG cable is wired the same way so it is very likely that it will work. (on Hungarian forums I saw references that it works, but I can not guaratee it.)
Tommorow I will go buy one and report.
USB Host mode will allow to connect USB pendrive, mouse, keyboard etc. to the SGS II.

this is very useful for people like me who knows how to solder things, but for the people who have absolutly no Idea what you are talking about, you should add more details/pictures to the OP so the people who doesen't know much about electronics know what you are talking about, and what benefits it brings for them.
I myself will probably make one or more, so I don't have to always take my USB OTG with me all the time.

Why be sorry. This forum is to help each other out.
OTG Cable USB (B) to Micro USB (A) Powered with AAA batteries
As one knows, Samsung has promised a HMI 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 !
Instead of shorting pin 4 and 5 from within the cable head, would it also be viable to short them from within the device itself? Say if I disassembled the phone to access the back of the female usb micro connector and soldered the pins. Would there be any damage caused if the permanently shorted pins 4 and 5 (within the device) is connected to a charging adapter/PC?
Hi,
I have a few questions regarding the extra functionality available through the USB adapter that I would be grateful if someone could answer. I really like the look of this device but am unsure about a few things.
1) Does the USB adapter (30pin to USB) allow charging at the same time?
2) Does anybody know if there is a docking station that will provide USB & HDMI out. It would be nice to use this device, attach a harddrive and output to a TV.
Thank you for your time!

i suppose it might be possible if you were to use a multi usb port adapter with the usb adapter. I am not really sure if that will work though.
I talked with Samsung support today asking if the USB dongle could be attached to a regular USB cable for charging and they said yes.
Hi All,
I have instlaled my nexus 7 in my car and would like to clarify a few bits.
OK been looking at two things - Firstly - using an external drive with the Nexus 7.
From what I have read and understand I need an OTG cable.
As I would like multiple usb devices connected such as mouse, keyboard webcam usb drive etc do I then connect the OTG cable to an external USB hub in order to connect the various devices? I guess my general question is - are you able to connect multiple USB devices to the Nexus 7 via the external HUB?
I'm presuming you need atleast a 2 amp charger and does plug directly into the External hub or into the Nexus itself?
I'm sure the answers exist somewhere on this site but there is a mountain of info and some of it contradictory.
Im unable to post links to cables I would need could anyone please do that so I know exactly what to purchase - I am in the uk.
Thanks for any help.
