[Q] No USB-OTG-Connection (CM11) - Galaxy Tab 2 Q&A, Help & Troubleshooting

I have some problems with USB-OTG-Connections (CM11 Nightly).
When I connect a USB-Stick it works as it should. But if I connect my Nikon DSLR (e.g. to do a tethered shooting with DSLRDashboard) the Camera is not detected by Android.
On my Galaxy S4 (rooted Samsung Kitkat) it works perfectly.
Any suggestions how to get it work on my Galaxy Tab2 as well?

Tab 2 supports only Pendrive,mouse,keyboard via OTG out of the box. If you wanna connect your camera with it,you need a powered USB HUB. S4 is a high end device; that's why it supports it by default.

That would take me a a lot of flexibility/mobility.
I want to mount my Tablet on my camera tripod.
My idea was, to use the y-cable that came with an external hdd and connect the power port to my 10.000 mAh Battery Pack to get the needed extra-power. I've tried that with the external hdd and it worked: The Galaxy Tab detected the hdd as SD-card and mounted it as usbdisk0.
But when i try the same with my Nikon instead of the hdd, neither Adroid nor the "OTG Troubleshooter" detect anything.

Try this app from Gplay DSLR
Edit :
Is it working on Touchwiz?

As mentioned before, I'm on CM11. Not Samsungs Touchwiz. Should I really flash the crappy Samsung-Software? Not sure how to switch back to the STOCK-ROM easily because I'm on CM for ages.
And how can this software help me with my problem? If Android is not detecting my Nikon Camera, I'm pretty sure DSLR Controller (for Canon) can't handle my Nikon too.
My connectivity-issue is some OSI-Layers below, isn't it?

(Q) anyone attempted to hook up their xoom to a camera?

So I'm still waiting for the 3.1 update sadly. And I'm curious if anyone attempted to hook up their xoom to any dslr or camera of any sort. This would certainly bring my dslr to a new level.
Yes I have. I've not a dslr but a digital camera capable of using the host function. What do you need to know?
Just basically how it handles the transfer. Do I need a file manager program like astro file manager? Can I specify the directory from and where the images go.

i pretty much got told i was an idiot in this post, and had my thread hijacked. screw those retards, im doing way more with my XOOM then they will dream of.
http://forum.xda-developers.com/showthread.php?t=1073396
i hooked mine up, works great. you dont need astro. it asks to import in gallery. If you want to move your photos around to edit on photoshop mobile, youll need it since galley puts the imports into a "imported" folder in the /sdcard root. photoshop mobile does not look there, it goes to DCIM.
apologies i missed this post but good answer from above there.
and photshop mobile.. is it any good? (partial thread hijack.. )
Also, be aware, it doesn't prompt for overwrites. I was testing it at work doing product photography. I imported the first batch of photos, picked the keepers and started the next batch, another person had disabled the sequential numbering on the camera so deleting the first batch from the SD card reset the counter. Upon importing the second batch, I lost all of my first batch.
Beyond that, it works quite well.
My rooted xoom on 3.1 does not even 'see' my canon 60D (and vice versa) when connected with my OTG cable
I know my OTG cable is fine because it works with all my flash drives, external HDDs, and card reader
Normally when I plug in the 60D to the computer, the camera turns itself into USB mode (cannot shoot photos), but when plugged to my xoom, it appears as if nothing is plugged in (still shoots photos properly)
Works great with pro SLR's!!!
Love it! I plugged my Nikon D3S, D3X and D700 pro SLR cameras into it and my pictures showed up in the gallery!!! This is a HUGE benefit since now I can leave my tablet PC at home and use the Xoom to quick email some proofs.
Now if only the Micro SD slot would work without rooting!
how about connecting usb hd webcam? (if powered from external source...)
is it possible to record videos from such camera?
Using Tiamat and Sony DSLR's hook up no problem as long as you use the special cable. I read that 3.1 will allow usb host too but I do not know how much more or less will be supported with stock vs the Tiamat kernel. Will you still need the special usb cable with 3.1 so that usbhost will work, or will any usb cable work? I know I tried with the Tiamat one and it did not work, which is why I ordered the special cable.
I've a Canon T2i and I can only import pictures as long they are jpgs. Does anybody imported RAW pictures (.CR2) into the xoom? I can't find the directory where my camera is mounted so I can move my pictures manually, it would be awesome if I can see my raw images but at least I want to use my xoom as a storage.
Thanks

Your camera most likely is in a USB Host mode and not PTP mode. I had the same problem with my camera. Its a simple fix just go to your camera USB options and set it to PTP. Also my camera needed power, it didn't when plugged into my MAC.
I have a video that shows this basically works. This highlights all the 3.1 features so I apologize for it not having just a video on that. But to see the OTG Camera Picture Import go to 6:20 in the video.

Hey, I also have a Canon but a 7D, can you try something for me?, hook up the camera, on the gallery go as if you were to import the pics and deselect all, then double click one to view the pic in full screen, now click once on the screen to pull up the scroll at the bottom that shows all the pics, scroll all the way to the last pic (I have about 300 on it) and see if your camera shows an error message 70 Shooting is not possible, bla bla... let me know how it goes.
Thanks
What kind of cable or adapter do I need to do this. Everything I have is used for plugging into my PC and obviously the end of the USB is way to big for this.
Ideas for best video conferencing app?

Having a similar issues with a rooted xoom running 3.1 and tiamat 1.4.2. as soon as i plug my t2i in it freezes the camera till it is unplugged. while plugged in nothing shows up in gallery to import. tried plugging in a samsung point and shoot also and no go. Trying to look into it further.
update:got bored and went back to 3.0.1 & relocked and got the ota update and my t2i works fine. now to reflash tiamat and see if it still works or if it is indeed the source of the problem.

do you happen to know how to use adb logcat? looking to see what your xoom is doing to access your t2i that mine isn't.edit: never mind i got it. and for your question: raw pictures are stored in a slightly different format for each camera and you would need a program that was compatible with the t2i's format in order to view them. The gallery simply doesn't have that functionality so you won't be able to import them. also, the t2i isn't mounted as a drive when plugged in so you won't be able to access the files directly.
thanks for the reminder, but unfortunately, i've checked many places, but the Canon 60D has no option to turn on PTP... guess i shall need to wait for a firmware update or something

how to mount a usb thumb drive in 3.1 stock?

wifi xoom running 3.1 (non-rooted)
I bought the Motorola Camera Connection Kit (OTG Cable), connected my digital camera and it worked perfect. However, I'm trying to see if i can plug in a usb thumb drive... but I can't get it to work? Do I need to do anything special to mount it? What filesystem would it mount as?
Thanks in advance
I may be wrong on this but I didn't think 3.1 stock had flash drive access...?
maybe I'm confused too then? I thought 3.1 added usb host support...
only for cameras, video game controllers, mouse and keyboard.
ahh, that explains it... thanks!
Is it using the camera protocol? My cameras have always shown up as mass storage on my computers. I haven't tried a camera on my xoom yet.
i just tried with my camera. it still won't work. guess we have to mount the drive.

got my Camera to work with Xoom. Just set the camera USB setting to MTP/PTP mode.
It cannot recognize raw image files.
works with my canon 5d m2 instantly without any setting changes
Anyone have a flip camcorder who could test that out?
Edit: I went and bought the camera connection kit. Was able to get videos off my flip by navigating to /mnt/usbOTG (with the flip attached obviously). I'm rooted and using the latest Tiamat kernel though. US WiFi model.

Media transfer protocol, otg cable, tiamat 1.4.4 and honeycomb

Hi all
I would like to connect my canon a470 powershot to my
Wifi only xoom, running tiamat 1.4.4 and honeycomb,
through an otg cable.the cable works and I can access USB
pens reading the content.Now as my camera does not
provide usb mass storage access but only mtp/ptp I cannot
manage to access photos directly plugging the USB cable.
I read that Verizon camera kit cable supports ptp on
Honeycomb systems but how? Is there any app or .ko
needed or is a compatibility issue related to my camera?
Thanks

I have the Motorola Xoom "camera " otg host cable. That's all the "kit " contains. I'm running the Tiamat ROM and I can not access my Canon Powershot either. So, if you have a working otg host cable, don't waste your money....
really ? nothing more than a simple OTG cable ? Thanks for the advice ! How is it supposed to work on stock ROM's if UMS is disabled ?
I 'm sure that there must a library for ptp/mtp on android: I read that some people had this feature working, being able to access photos (stored on the camera) through the stock gallery app.
Maybe the OTG cable is not enough...
Could be the camera brand. I have no idea though. I don't need to connect any of my cameras to my xoom.
Bumpity bump
Any resolution to this?
I have USB sticks working too but not ptp supported devices...
I'm having the same problem with my Canon 5D. Also tried Canon Ixus 130 and that didn't work either. I just tried installing the stock Australian image and then installing the 3.1 update and that does not work either... I asked around and found people that also had a canon 5D and Xoom and the combo worked for them.
that is so weird
I wish someone can shed some light on this...is this inherent with 3.1?
Do not know will this help in any meaningful way but did anyone tried connecting A470 running chdk? I do not have Xoom but there exist plethora of scripts for canon low end cameras making them just a little bit more useful. Higher end cameras have another way of enhancement with different program setting. Just my to cents...

Note 10.1 and OTG

Hi.
Now and then I use my OTG connnector for things such as a pendrive or my xbox 360 controller.
I'm having a hard time fot the tablet to read them so I found my work around is to reset my device and then connect either one of them and not as intended....kind of annoying of course.
Any ideas of what I'm doing wrong ?
Thanks

With the latest Galaxy Note 10.1 update in the UK, suddenly I can't run the PS3 controller or USB Memory card reader that I used previous to the update. Fortunately, though, they both still work on my Galaxy Note phone. I would be interested in finding out if there is a workaround to get USB OTG working again on my 10.1

From everything I've read, OTG is problematic on JB 4.1.2. Some report certain OTG cables work while some report that none work. The bad news is that Google broke Bluetooth on JB 4.2 and still can't resolve that issue with the latest release. Truthfully, I'm happy to sit back and let Nexus device users discover major bugs introduced in the constant stream of updates that Google pushes out. They end up doing the beta testing that Google doesn't seem to do very well in house. I wish Google would take the time to thoroughly beta test in house and only release an annual update. They really have egg on their faces with the Bluetooth fiasco.
Otg is working for me with 4.1.2 stock, rooted N8010XXUCMA8
I tried samsung usb connector, powered usb hub with wireless keyboard/mouse, thumbdrive fat32, and hard drive (one partition ext4).
All worked together. Windows fat formatted partitions on thumbdrive and hard drive mounted automatically, ext4 mounted ok manually.
OTG works for me also... My main issue is that sometimes I have to reboot my tablet in order to get my pen drive or Xbox controller working... A little annoying

Nexus Media Importer
I tested the Nexus Media Impoter App on my Note 10.1 German Stockrom (ma8)..
And now I can read from my hard drive with external power ,which is formated to NTFS..
The problem is that after I connected the hard drive to my note 10.1 it shows me a notification : Clear Storage or something like that..
please don´t touch on it ! after a few seconds pops up a message from nexus media importer in the middle of the screen to accept media importer as default app.. after that Nexus media importer starts and i can read on my hard drive
The App lets you only read and copy (not tested yet) from the hard drive!!!
To close the app tap on settings in the top right corner and chose disconnect !!
The app will close and the " Clear Storage" notification will show up but that doesn´t matter my hard drive was succesfully disconnected.
I hope I could help someone who want only read from his hard drive
ah and video plays very smooth
last but not least i don´t know if it works for everyone!!
sorry for my bad english

At times like these I use USB Host Diagnostics by Chainfire

Do this.
Unplug your otg cable from you galaxy note 10.1
Download an app called "usb otg helper" (the free version) from the google play store.
Run the app
Plug you usb drive into your otg cable
Plug your otg cable into your galaxy note 10.1
A window will pop up. Check the box that say something along the lines of "let usb otg helper handle all usb devices plugged into this device"
A file manager window should open on top of the usb otg helper app (astro file manager popped up on my screen)
In that file manage window, navigate to your storage folder. Is your storage folder, you should see sdcard01 (this is your internal sd card [16gig or 32 gig, depending on which version of the tablet you bought]), extsdcard (if you have an external sd card loaded in your slot), and UsbDriveA (the usb drive you plugged into your otg cable)
If you checked the box that asked if you want usb otg helper to handle all of your usb devices, the usb otg helper app will always automatically mount your usb drive everytime you plug in your usb drive via the otg cable.
IMPORTANT NOTE
in order for your galaxy note 10.1 to recognize your usb drive, YOU MUST PLUG YOUR USB DRIVE INTO YOUR OTG CABLE before YOU PLUG YOUR OTG CABLE INTO YOUR TABLET.
otherwise your tablet will only recognize the otg cable, and not the usb device.
I need more time to figure out the deal with the ps3 controller.
My HTC One S used to recognize my ps3 controller at one point and now the same ps3 controller is not being recognized by my galaxy note 10.1 or my htc one s.
I think that my problem with my ps3 controller has something to do with me getting the ps3 controller to work with games on my windows pc.
Once I figure out the solution to the ps3 controller issue, I'll post it here.
Ir this helped you, hit the thanks buttom.

it's the reason why i will never upgrade to jellybean on my note 10.1 i play a lot of gta 3 on it and i don't want to use the touch screen for controls, that would be horrible, i'm hoping that with 4.3 hopefully the problem can be resolved but i won't hold my breath on that matter.
Doesn't work for me, unfortunately. USB devices are only recognized immedeately after a reboot. The OTG helper app doesn't change that.
Mine works well on stock rooted. With a usb hub with 2 8gb pen drives, one formated to ntfs.

[Q] USB-OTG

Hello,
I've got a Samsung Galaxy Young N (gt-s6310n) with Android 4.1.2, rooted. I've installed an app to control my DSLR camera from my phone. The app runs normally, and both the Camera and the OS are supported (I don't know for the phone, but the app always start). I bought a OTG cable, recommended also by the app.
The problem is that when I launch the app, it doesn't recognize the camera, also if it's connected. The only problem that there might be is that the OTG is not abled on the phone. How can I able it?

OTG can be enabled via kernel editing, but the phone's hardware must also support OTG....and in the case of this phone I don't think it have a hardware OTG support.
