Directly connect Smartphone with External USB Powered HD? - General Topics

Just wondering if this is possible, and if so, which phones and OS's will support this. More specifically, will the Samsung Nexus S be able to browse filles off of my WD USB3.0 My Passport Essential SE 1TB?

i have seen something done in this regard where that guy used a "fake" microSD to act as one end of a USB cable. the other end was a regular usb port where he hooked a usb thumb drive. you might try to find it and see if it applies on your case.

only o2 flame can do usb otg
but slow in transfer rate as usb 1.1

I have a similar question.Can i somehow send pictures from a USB device to my iPhone? I really need to get those pictures on my phone. Is there a way other than using my pc?

[Q] USB stick plug and play

Hi,
This may be quite a retarded question but here we go anyway:
The Nokia N8 is capable of hosting a USB stick via the medium of a micro USB adapter. i.e. You can plug a USB stick using a micro USB adapter into the N8 and it will mount it as an extra drive displayed in a file explorer.
Is this possible with the Nexus S/Android platform at all?
Presumably drivers would need to be sourced somewhere, and some form of Linux based hack...
Any ideas?
Cheers,
Andy
i'd love to see that happen in the SNS
but from what we know so far, it's not yet possible
however the guys over at SGS, are already cracking in on the code, to hack it and make it work.
as soon as they get that working it should be simple to port it over to SNS, as the phones are practically the same

[Q] Re: Nexus S usb host is not working

http://support.google.com/ics/nexus/bin/answer.py?hl=en&answer=2386439&topic=2375623&ctx=topic
According to the official Google Help Page, it should support USB Host. However searching online have returned a lot of out-dated threads about how the USB chip works when it was still running Gingerbread.
I have purchased a USB adapter, tried to connect any USB device to my Nexus S, and nothing happens. The USB port will not be powered. However quoting Google's official help text :
You may need an adapter to connect the keyboard or other device to your phone's USB port. To connect more than one USB device at a time, use a powered USB hub to reduce the drain on your phone’s battery.
This implies that connecting devices to your Nexus S will drain your battery?
I am very confused. I have no powered USB hubs so I cannot try to see if the USB host function is purely limited by the lack of power or the USB chip.
I am sure I am not the only person who would love this to work. Is there anyone who knows what does it take to get USB Host to work on Nexus S upgraded to ICS? (Despite Google's help site indicating that it should just works out of the box)
Thanks a lot.
So, I spent some money and bought a powered USB hub.
No it didn't work.
I think the reason is that the power is not being transferred UPSTREAM. For example, I have connected the USB hub to my Nexus S, and a Logitech wireless mouse receiver to the powered USB hub.
Although I am sure that the Logitech wireless mouse receiver has power (from the USB hub), the Nexus S does not recognize the existence of the USB hub, since the power is not transmitted from the USB hub back INTO the Nexus S.
Feeling disappointed, I repacked everything nicely and exchanged my purchase for a slightly more useful 16GB SD Card.
Does anyone has any information to how is this supposed to work?
Or should we assume Google has made a stupid typo in their help articles, and that the Nexus S will not actually work in USB Host Mode ??
anyone please?
I too am looking for answers. Anyone?

micro usb to usb adapter

Here's another cross post from General/General (don't worry, I'll clean up after myself).
Here's a cross post from the Mesmerize thread where I'm not having any luck:
I have a 2.2.1 (rooted) Mesmerize and I can't get it to recognize anything plugged into the Samsung Micro USB to USB Adapter I just bought.
The phone is set to "Mass Storage" for USB and I've tried both USB Debugging on and off.
I can't get it to recognize any of 5 thumb drives that I've tried connecting to it. So either it's a bad cable, or something else in the phone is preventing the connection. Help, please!
EDIT: I'm possibly naive in assuming that this (reading a USB thumb drive from the phone) will work at all, but since they (Samsung) sell the cable and tout it as being capable of it, I must just be missing something such as a setting or the necessary version of Android or a wonderful hack from this group.
You are looking for something called USB hosting. It is a nice feature that hasn't been implemented on many devices.
It would be nice, but you would need an intermediate usb adapter that supplies power to the thumbdrive, as I doubt that the phone is capable of supplying power for very long.

[Q] External USB Adapter

I've heard that the External USB Adapter from ASUS is a notoriously difficult beast to locate. It's marketed to plug into a bare tablet and provide a Host USB connector. But, would it also work in the charging port of the keyboard dock giving a second Host USB port? (Yes, I know a hub would do this. But If one wants this device to connect USB storage to a bare tablet, would it also do double duty and work with the dock?)
It certainly sounds possible. Mostly because I think the internals of the keyboard dock are a hub already basically.
One usb going to the card reader, one going to the usb port, one to the keyboard function, and another as a passthrough to the proprietary data port.
So by using the usb adapter you are just converting the otherwise unused data port into another usb port.
since there both 40 pin connecters i imagine that would work

That is also my assumption, but we all know what assuming does. All depends if all the signals are passed through, and if there are any lag or transmission line issues.
Has anyone tried this to verify if it does or does not work?

Usb cable or dock that can be used to transfer data but uses separate power source.

I would like to know if this exists, as if it doesn't I was thinking about making it. As the title may be confusing to understand, maybe describing what I'm trying to do will be easier to explain.
I going to create a dock in a family mini van for a tablet. This tablet will have limited storage space, but has usb otg capabilities. Thus hooking up a flash drive with movies on it would be the goal.
Now running a female to male cable would be fairly easy, however I want to be able to have the tablet charge and still use the usb port to access the usb cable. Thus I need a cable that may be spliced cable with three ends. Where two ends are for usb transfer and another to supply power to the devices. Or if there is another solution, I am up for it.

I have seen Y cables for such a purpose.
If you want to do charge/power and USB host at the same time
you will need the plug into the Android to be an OTG plug with a grounded ID pin.
The other end will go to the flash drive.
If you apply 5V to the Vbus/Gnd your device has the possibility to use this power.
Of course this is an odd situation and it may ignore the 5V and only use its own battery.
Experimenting will show you if this will work without a driver hack.
