Has anybody tried using USB otg with 2.5" self powered hard drive?
I tried my 1tb western digital passport and it doesn't even power.
Flash drives work fine. Using stock kernel BTW.

Havent tried mine..but I dun think It works since it need more power..

Could u check? I checked on n7 forum, some worked for them

I am not an expert on the subject but maybe its the lack of power. Try a powered usb hub or something if possible. Again I am no expert but usb 3.0 compatible devices usually make use of the extra power allotment to be "self powering" unlike in usb 2.0. So I am guessing it is a power issue.

I see. I just tried my friend's s4 and was working for him!!

keep in mind that must be partitioned as FAT in order to see the content of the drive via OTG. i don't think NTFS is supported. i hear there are custom modded kernels for samsung phones that support NTFS but that's not the case with regular kernels

I've got a 2.5" ToughDrive and the OTG cable I have won't supply enough juice to power that.
The cable works fine with USB pen drives but that's it.
I haven't found an OTG cable that had a power input to support more power-hungry drives.

Does Droid 4 have Host USB capability? In Lapdock it should but what about other methods.
Theoretically Droid 3 didn't have HostUSB functionality, but when you did connect it to Lapdock or HD Dock with USB the ports were supported and there were even app for supporting flash drives. The only with ancestor was that USB didn't have power so you couldn't use cables that have microUSB/USB to connect devices.
droid 4 will do usb host with a few caveats.
It will only do fat32 formated flash drives.
you need to power the drive off another device.
basically you need a usb otg (micro male on one end, usb female on the other) and a usb hub that uses an ac adaptor. The hub with power cord provides the power for the device, and the OTG cable is for the data. This can also be achieved using a powered y cable in place of the hub, but you would need to have the power-only usb port plugged in to a power source.

Has anybody tried Remote Release with the Droid 4? It does Canon DSLR and normally works with Galaxy S2 and 3 without rooting.
Using a USB OTG cable I've connected my Canon DSLR but I had now joy unfortunately...it doesn't recognise anything. Also I've tried keyboard and mouse but that doesn't seem to be working either. Am I missing something

Thanks, I've seen this already. I guess what I was looking for is to understand whether everything OTG needs power or just things like keyboard/mouse/pendrive - things that actually consume it. TBH the DSLR camera itself is not actually being charged or anything, it is just DATA, so I was sort of hoping that I can avoid.
Out of all the devices i have tried all have needed external power... prior to the purchase of an HD docking station I just used a powered USB hub with an otg cable....

I think I've made an assumption that it would behave similar to my android tablet, just plug in the pendrive and it's all good. I have defo came across devices that don't need external power, especially for a camera that doesn't take power.

I'M thinking about getting a nexus 7. Question about it's USB OTG capability: Can it connect to multiple things at once through a USB host? I am thinking the ultimate portable workplace would be a portable keyboard, mouse, a microSD reader, and a charging cable all coming from a single host. Is Android at the point where this sort of thing is possible yet?

No, currently you can connect to 1 slave usb device, maybe 2 with the use of an Y splitter cable, if at that. Am not sure if it's a software or hardware limitation.

With usb otg cable pluged in usb hub you can connect more devices.

You should know though that while using USB OTG (if i recall correctly) you are not able to charge the N7 at the same time. It is either one or the other.
While using OTG can charging if flash patched kernel.

Thats what I am gonna xo, as soon as my y- cable arrives.
I'm thinking of getting a Bluetooth keyboard

Awesome! Can't wait for more kernals incorporate it.
Anyone had any luck with these cables? Specifically using an external DAC while still powering the phone. It's possible on my Nexus 7 with a custom kernel.

I am using one of these cables, but in a different manner, ie I am accessing a WD Passport 1TB external drive. (does not have ac in) Both my drive is powered AND my phone is charged. (tried using both a 10kmAh external battery pack as well is direct AC adapter.
Know it's not exactly the setup you are using, but as far as cables go, the phone seems to work well with this setup. YMMV

If I may ask, where did you get the cable? The only one I found so far is on Amazon and review there say that it will not charge the phone, just the external device.

Got the same cable and its not working, do we need a special kernel to make it work?
Sent from my GT-N8000 using xda app-developers app
On my Nexus, I did have to flash the right kernel. I'm guessing that will have to happen here too.
Why not make a cable that will charge and otg

Just an update. I ordered one of these http://item.mobileweb.ebay.com/viewitem?itemId=261170130579&index=0&nav=SEARCH&nid=87388073446
Should have it next week to test but based on the seller's description and testing on similar devices, sounds promising. I'll report back.
I have just bought it.
Initially USB hosting works, but I have no chance to charge at this time.
-----update-----
The female micro USB jack does not charge the phone like the one for Galaxy Tab.
Do you think we still need to add a 40.2k ohm resistor just in the galaxy s3 and will a stock kernel work?

I would like to add I managed to get an OTG + charging cable working for the Note 2 (N7100) using a cable made with these instructions: http://forum.xda-developers.com/showthread.php?t=1953061
But... the 4.1.2 update stopped the USB from working on my Note 2, and someone else is reporting a similar problem: http://forum.xda-developers.com/showpost.php?p=38611244&postcount=42 . What happens is the Note 2 does detect it's using a dock, but the USB functionality doesn't work for some odd reason (even after a reboot).
I will reply again if it starts working in a future update.

Probably the same as the s3 - shorted pins = otg+no charging, resistor fools the phone into thinking it has an accessory/dock that can charge safely.

It sees that it's in a "dock" but nothing I plug in will work. It does charge though. If I short out the pins I get host mode, but no charging. This is with the Jedi rom, not stock.

The pen drive you are using requires more power than the phone can deliver.
You may need another pendrive for it to work. I have two pendrives, one works, and one does not
Use a USB hub in between, I know it doesn't make much sense, but this is how I get around the power consumption error.

Try it and see, but I don't think so....not enough power (Let alone not enough micro usb ports on the phone)
Do you know any adapters that would support it?

No, but some people have made some of their own. It may be possible to get the connections correct, I just think you will struggle for power. What are you planning in running un the OTG at the same time as a MHL connection
Something like Acer Extend... To use my phone as a terminal for Remote Desktop and ssh.

You could try a powered hub with a micro usb female port but Im not sure if it would work or not. I know via a powered hub you can have several devices connected at the same time but to include MHL I'm really not sure. Is there an MHL cable with a female USB / micro USB slot in it? So you could connect the MHL directly into the phone and then potentially feed the USB hub from it? Not sure m8.
