[Q] Multi-purpose OTG? - Nexus 7 Accessories

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

30 pin galaxy tab to micro USB adapter

Hi, I I recently bought this adapter online so i don't have to carry two separate cables when I travel (one for tab, and other for phone).
http://www.ebay.com/itm/Samsung-Gal...rs_Chargers&hash=item19c4c95c01#ht_1561wt_802
This product works well as it allows you to charge your tab with a micro sd cable and standard tab wall charger or any charger with usb dongle. If you have any questions let me know, I but I highly recommend this to all tab users who also have phones that charge through micro usb.

What I want to try next is to plug my s2 otg cable into the adapter and get host mode.
If anyone can link me to the kernel that works with overcome let me know.

Thanks for the tip bro. Orderd it when you posted and got it sent yesterday. Should be here next week
Never thought of the host capabilities thou. Another reason to get one

I have (2) different micro usb host cables for galaxy s 2 and I was thinking of trying to consolidate and use them here too but I don't know how to compile a kernel with host capabilities.
If someone where to be able to make one for me that will work with overcome I can test this.

May want to edit OP to reflect MicroUSB, not MicroSD - Might be helpful.

Got mine yesterday. Works Recomended!
I was gonna buy 1 but the description says "Computer + micro usb data cable can not charge. Please use the original wall adapter to charge with this cable!"
is it true that when you plug it in to a computer it will only do data but won't charge the battery?

If you want to use a computer or an usb wall charger you can buy a USB DC dongle and it will charge.
Ill link you to the one I have.

Interesting! What magic is making this happen? I thought usb was limited to 500ma draw before the computer starts complaining. Is this safe? I mean, it works, thats great but i'd love to know why/how?
No idea... but it charges for me. Slower than from the original USB wall charger but it will charge.

Nice! This is exactly what I was looking for, as I've repurposed my P1000 as a head unit and need to charge it in the car while it's in use, and didn't have any success hacking together a cable with resistors to do the trick.
what about file sync? i mean can it work like regular usb cable to connect tab2 to PC, for file managment and stuff?
it should be possible, since it's regular usb2.0 on the other side of the cable and micro-usb is just the same wiring but smaller...
so i noticed it doesn't charge from a PC's usb, and it will do if i use magical adapter mentioned in replies here, right?
The Question is = will it allow file management and charging at the same time if i use micro-usb and usb-charge adapter?
also found this: http://www.alibaba.com/product-gs/592818965/for_Samsung_Galaxy_Tab_USB_Adapter.html
it only states that it charges over micro-usb, not sure if it can transfer data.
and this: http://www.sunsky-online.com/view/232254.htm
this states that it's for P1000 (dunno, do they have same connector?) and it doesn't clarify if it's for charging only or can transfer data

Turtlebeach Setup Question

I have a 360 and I use the 360 wireless adapter which currently occupies the USB port on the back.
I see that the Turtlebeach requires me to plug this into the back USB port.
What's the best way to go about this? No, I will not use Ethernet cable or get the new Xbox.

Max. (From my Galaxy 2)
I have to look for a hub but I don't know if that'll work. This headset is hella complicated.
Sent from my SPH-D710 using XDA App
No it doesn't need to be plugged into the back port. You can use any USB port (even one from your computer). The back port is recommended because it only provides power thus freeing up the other USB ports for things that don't only need power for
Or at least I think so. Either way any USB on your Xbox will work for your Turtle Beaches.
Cool. I will try it now. This thing is a beast. I didn't think people took mics this serious. My GF got it for me.

[Q] Host USB on Droid 4

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.
edit: link to y cable image for better explanation

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.

1tb hard drive via USB otg

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.

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.

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.

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.
