I have a OTG cable for my nexus 7. I need to connect it up to my computer and a mouse at the same time with a USB hub, How can i connect it to my computer. I have tried a usb-usb cable with no luck
I wonder if a wifi usb dongle would work. I hate that I had to call it a dongle, but I can't think of another word for it right now.
The tablet can either be a host (for the mouse device) or a device (for the PC host), not both at the same time. If you want to use adb while using a mouse, look into wireless adb.
Try Timur's USB Rom

I was wondering, can you use a usb otg with a usb hub so that you can use a keyboard and charge the N7 at the same time?
It probably won't work with a USB hub, because the side of the hub that plugs into the tablet wants to receive power, not give it.
But you can use a Y cable and one of the kernels that provide OTG charging, like Timur's kernel, faux123 kernel, and probably others. Search Google for 'Nexus 7 OTG charging'.

Hi,
I want to connect my pendrive/usb mouse to my milestone via USB 2.0 A Female to Micro-B Male Adapter cable. but milestone is not able to connect it. nothing happens when i connect the cable to it in its microusb port.
I tried the same in Samsung galaxy SII (unrooted) and it worked well.
I am using [ROM] CyanogenMod 7.1.5 (Android 2.3.7).
I want to know whether the milestone lacks some hardware capabilities or it depends upon ROM?
Use sixaxis men!!!
Wow! mmm.... i dont think that was possible but You could try SIXAXIS to connect a joystick at least. So you can use it like a mouse or any you want without any cables. (Sorry. My english is not so good).
IIRC mounting a usb flash drive should work but only if you plug it in before you turn on your phone.
ie turn off phone, insert OTG usb adapter, insert thumb drive, turn on phone.
But if you remove it after, you will have to repeat the process. Search the dev forum.
USB OTG supported?
I thought USB OTG was not supported on this phone. Does it really work?
IIRC, I think some work was done to try to compile a kernel module to enable support, but it stalled out when they realized there was voltage issues.
I just got pdmi(dell streak usb) to usb otg cable, but it dont powerup any device. I'm using dell streak stock rom android 3.2. I think it's kernel doesn't support usb host api. Can somebody tell me any solution?
Thanks in advance
Problem is fixed
There is no any problem with the usb host api, kernel or drivers. It was due to the power (voltage) coming from host port, and It can be fixed using any extrnal usb power source,
1. you can use a usb cable which has a female usb on one side and two male usb on other side i.e. usb female to 2 male Y cable. You can buy it from ebay, use usb Y cable keyword.
I also try, multiple devices on dell streak usb host cable, using usb hub. It was working properly.
You can use es file explorer for data transfer.
steps to follow:
0. Root your dell streak and install USB OTG Helper.apk from android play store.
1. Switchoff dell streak 7,
2. Connect dell usb host cable (pdmi to usb otg adapter) to male connector of usb Y cable, and then connect usb device to female connector of usb Y cable.
3. Switch on dell streak 7.
4. After, Dell streak lock screen, connect another male connector of usb Y cable to power source (Dell Ac adapter).
5. go to usb otg helper and click on mount, it can may start adobe reader, don't worry.
6. go to es file explorer, and your drive is usb_drive_1.
God Bless You All......

I dont believe any kernel on the S7 ever supported OTG, the stock 5xx ones definitely dont. Even if they did you likely have to supply your own power as the S5 did get working OTG kernels but the S5 never supplied power.
No OTG because dell didn't give us the drivers.

Definitely works fine as long as you supply external power. Tested and working with mouse, keyboard, and Logitech gamepad.

Hello,
I have a USB OTG cable and dell keyboard that I have tested and work in OTG mode on a Nexus 7, however i cannot get them to function with my HP Touchpad 32gb, running CM9 2.6.35, built on Sun Oct 28.
The device recognizes when I plug in anything via USB, but only as a generic Linux USB hub, and not as any particular device. Are there any steps to take to debug this? Has anyone had experience with this type of an issue?
Thanks for your help,
Cory
I don't know if this is the issue, but I know the touchpad doesn't support OTG like the the Nexus does. I think you need a Y-adapter + OTG to provide power since the micro usb port doesn't give any power to the device you connect. Someone correct me if I'm wrong though.
Apparently even a powered USB requires a powered Y cable to be properly recognized. I hacked together a quick Y cable manually, by splicing in another USB cable's power and ground (Red and black) to the respective locations on a female USB cable. Works as expected.
I am now communicating with an Arduino over Serial
Thanks!
Read this thread, should give you all the info you need:

Basically the Touchpad has OTG but it provides no power.

if so , he is the first of the many many many who has used this cable..HPTP just is not set up for charge + usb data at the same time

Agreed. I think people just are not stating reality regarding the ability to charge and use OTG Hosting to USB devices at the same time.
My goal here has been to attach a flash drive with video/audio media and play & charge on long flights. It looks like play, charge are mutually exclusive on my beloved TouchPad.
I've asked for the specific confirmation of this from this YouTube but have never had the poster reply:

There are devices out there that have very advanced micro USB device implementations. Sadly the HP is only superficially supportive.
I for one cannot wait to get my SGN2 smart dock which offers:
Charging
OTG (x3 USB)
Audio out
HML HDMI out

Hi friends,
I want to attach to my touchpad memory card reader and external hard drive.
I wonder if it will be possible instead of buying Y cable and connect it to the OTG, to use my existing USB hub and connect to him the devices and the external battery bank.
Will it work?
Thanks

im assuming youre talking about doing this in android 4.0.x +. if so then yes you should be able to connect an externally powered usb hub to the OTG cable and connect more than one device at a time.
Thanks

Yes android 4.
to be precise, I don't have powered usb hub.
I have normal usb hub which I will connect him the power with usb battery bank device.
will it work?

Yes. You need to give power to the periphal usb devices. I tried the same yesterday, without problems.
Hey all
I have a powered Belkin USB hub (this one: http://www.belkin.com/us/F4U040-Belkin/p/P-F4U040), coupled with an OTG cable which I know work together, as my Kindle Fire recognizes all USB devices through this setup (Keyboard, Mouse, Flash Drive etc).
I was surprised to find that my HP touchpad does not recognize any devices connected to this hub.
I did some diagnostics with USB Device Utility, and the touchpad recognizes my USB OTG cable, as it shows as a 'Qualcomm On-Chip EHCI Host Controller'.
The touchpad simply does not see anything plugged into the hub, be it a keyboard, mouse or flash drive.
Please help me here, guys!
What am I doing wrong?
Thanks

Are you sure that's powered? The picture doesn't show any DC connectors. Is it powered by something like a mini USB to USB cable on the back? If so, that might not be enough to power the device and the peripherals attached to the ports.

The belkin does have an external dc power supply and is not powered via usb
I think you need a Y cable even with a powered hub as its purpose is to inject power back into the OTG chip in the Touchpad.
I am trying to find a USB hub that will work well with my Nexus 7, via an OTG cable, for a semi fixed car installation. I picked up one of these USB hubs a week or two ago, but I am not sure its going to be reliable enough.
I tested out with my iPod, plugged directly into the OTG cable, the Nexus picks it up and allows me to use it as external storage. I then plugged the hub into the OTG cable (Nexus also plugged into charger), plugged the iPod into the hub, and the Nexus tries to connect to the iPod. But, for some reason fails to do so. In the process I can see it mount/unmount to the point that the iPod freezes. When I have all of this set up in my car I want to be able to reliably run the following:
USB Flash Drive 128GB/256GB (in place of the iPod)
USB-DAC
Joycon board (steering wheel controls)
Easycap (reverse camera)
Are there any recommended USB hubs that will work? Since tihs will be installed behind the dash, I want to put something in there, and then essentially forget about it.
Thanks.
Try this, unplug the usb hub, plug all your devices into the hub then connect it back to the otg. You might need a powered hub but try the method I just listed first. Also, are you rooted and have stick mount installed?

I think I already tried this, but will give it another go. I also tried plugging the USB hub into my laptop, still a no-go on the iPod. Everything else I plugged in worked though, but none of it was pulling much power (headset, mouse, cell phone). I could not find a flash drive anywhere at home, so am waiting to pick one up before I try again with a flash drive.

Yes rooted, but do not have stick mount installed as using Timur's ROM, so no need for stick mount.
