USB Adapter with a USB hub

Hello all,
I received my USB adapter from Samsung today and am pleased to inform you that it works wonderfully with a USB hub. My hub has 4 slots on it and the tab was playing well with multiple USB devices being plugged in.

Really? I guess usb hub is needed to make things work? i had all kinds of issues. Mainly, not reading some usb drives, and memory reader. I just plugged the usb drive, directly into the usb adapter. The memory card reader was connected by standard usb to mini usb cable. That didn't work.
I got to try this.
Thanks.

No problem. I actually have not tried storage devices yet, only input devices. I posted on your other thread as well.
I have a feeling thumb drives may be having a problem if they are formatted in the FAT32 file system. I am going to try an NTFS drive and external hard drive and will let you know my results.
UPDATE: It appears I had it the other way around. I plugged in an NTFS drive to no avail, then formatted it to FAT32 and it worked.

FAT32 works great. NTFS is completely missing from stock kernels, it's in pershoot's "lib" extra modules archive on his kernels. However, I tried an NTFS drive using the extra module and it failed. (might require some manual mount magic???) It would take a lot more work to get FUSE working properly, and that's needed for the (vastly superior) ntfs-3g driver.

So does it work with external usb hard drives (both self powered and plug powered) of the sizes of 500GB and more?

what brand/type
what brand/type of usb hub do you have

If the hub is powered then the drive should work fine. You just can't use a usb powered drive without a power source

Ican't get mine to read my game controllers. Says something about high powered device. It won't let me read the message. When I tap it to make it bigger it just goes away. I am very frustrated. Can you get a fame controller to work? I used ps3.

PS3 controllers require a special driver. It may also require too much current since it tries to charge via USB. You'll need a powered hub if that is the case.
Gonna try my PS3 controller in a few minutes.
Edit: So far:
No excessive current errors from my PS3 controller - however mine has a fully charged battery because it's been plugged into a PS3 that has only been playing movies/videos for weeks. However button presses aren't recognized by anything. My guess is that if I dmesg I'll get an unrecognized device error. PS3 controllers are nonstandard.
However a Nyko AirFlo controller worked fine in SNES9x EX. It was semi-recognized by SNESoid - the keymap screen recognized something was being pressed, but games themselves wouldn't register presses.
Edit 2: PS3 controllers require the hid-sony kernel module to be loaded. This is included in pershoot's optional "lib" archive with his kernels. I had to hit the PS button to get it to turn on and start sending presses to the tab. No excessive current errors, but my controller was fully charged.

Thanks. But for some reason the ps3 and the x box controller worked for the xoom. I called samsung and they don't have any help for this issue yet. Can you get any external device to work for at least over fifty percent of what the adapter is meant to do? Did you get any error messages. I get high powered device connected. Then it say underneath that out could not connect. Device needs............. I cant read the rest. When I tap it to enlarge and read it disappears. Samsung can't figure out why that is happening either. Plz help.

Make sure the PS3 controller is fully charged before you connect it. If it isn't, it'll try to charge the battery and that's probably what sets off the overcurrent protection.
As to it working with the Xoom - I'd be VERY surprised if it worked with the Xoom when stock. Not so surprised about custom kernels, adding those modules is one of the first things people add, and the Xoom guys may have figured out module autoloading.

Thanks going to try now

wish i'd have read this before i bought it. i assumed it would since every other android tablet i have/had can power my external hds. pretty much makes it useless for me now as i was hoping to use it as external storage and for easy, quick file transfers. tf, xoom, and archos all work fine.

It works on a stock 3.1 build, it was one of those new features hyped at google i/o. I have both the European XOom and the Galaxy tab. The xoom copes fine with the ps3 and my other usb only non brand gamepad. The galaxy tab give me the hipower usb device error.

For SNESoid, you probably forgot to go into the other settings menu and turn on external input. The names may be off, but in addition to setting the key mappings, you have to turn on another option for it to see additional input devices, and then your gamepad will work

I had troubles reading an SD card with an old USB reader I had lying around. It was hit and miss.
Then I bought this SD card reader at Fry's for $4.99 and it works perfectly.

So, just to be clear, you are using a male A-A USB cable with one end plugged into the USB adapter on the GTab and the other end into one of the available USB ports in the hub, right?

Will my tablet recognise my Sony Handycam? Can i upload videos to youtube from it?

Hey guys
So basically I have a Sony Handycam DCR-HC19E camcorder, and was wondering if i plugged it into my galaxy tab using the samsung usb adapter thing, will it recognise it and allow me to take and transfer files to and from the tab?
As i want to upload some videos to youtube but it wont work on my computer?
So im basically asking if anybody has got mass storage access to devices they have plugged into the tab 10.1
Thanks in advance for any help
Adam

I have a Sony dcr-sr100. It mounts to my galaxy tab 10.1 on stock firmware.
I have found that " high" powered USB devices are rejected by this tab, which is annoying. But i have found that how you connect the devices matter also.
E.g. if the adaptor is plugged in then i use my USB drive to the adapter is does not work.
If my USB drive is plugged into the adapter then into the tab it usually works, if not pull out and try again right away.
If you can get a powered USB hub, this will help for connecting more devices. Generic keyboard & mice work fine ( if not " high" powered)
USB mass storage otg app in the market will help to mount more drives at once and enable access to NTFS formatted drives which are not supported on the stock firmware.

I don't see much point paying more than this.
Also the " card reader" versions are designed to only mount one card at a time since that is how the stock device handles otg. But if you already have USB card reader your happy with, it can be used with USB mass storage OTG app from the market. ( Which also adds NTFS support).

I got the corded version, as I thought it was more risky using the "Block" style one that might break the connector 30pin if it was knocked too hard.
There is rick of the corded version breaking on the cable, but it is a cheap replacement fix.

Connect my Hox to Xbox 360.

Hi all ,Don't know if there's a fix or am I doing it wrong.Basically I've got xvid films on my Hox and want to play them through my Xbox360.
I'm getting as far as hooking the Hox to Xbox360 via USB but phones not being recognised. Please help........

i take it you set it to be in mass storage mode?
the hox goes into mtp mode i think - i couldn't get it to work with my tf300, same results that you got.
possibly to do with it mounting it as mtp device rather than just as a basic sd card

Yeah I selected mount as hard drive but no joy.
Do you or anyone have a workaround ?
Sent from my HTC One X using xda app-developers app

i've had a quick look just now, this indicates that android should be able to - i haven't tried it since tf300 jb update, so maybe it works on that now.
what you need, is support on the xbox 360 to read the mtp device. supposedly ps3 and xbox both have support for it, but theres a lot of others having troubles with the galaxy nexus (mtp) as well.
you could try using dlna? that would do what you need.. i've used imediashare lite (can't remember if it was on hox though) a while ago with decent results.
or failing the dlna method, you could use a mhl cable to connect it directly to your tv to watch the videos.

Nah the nexus 7 does.
Can clearly tell as with the n7 when plugged in shows as n7 in computer then within that is internal storage
Whereas the Onex once mounted is just listed like any other flash drive
It is weird why you can't get it to work though
I haven't personally tried with the 360 but when I have plugged it into my car head unit and mounted I have been able to navigate the storage and play music accordingly

[Q] Why won't USB OTG work correctly? (Galaxy Note 2 N7100 x - demo version)

I have a demo Galaxy Note 2, which is running on the Revolution HD 8.0 rom. I flashed the following PIT file;
PIT_N7100_16GB_20121102.pit
The device works perfectly; very smooth, no FC's, the full 10.16GB of system space etc etc. However, one issue I am having is getting USB OTG to work.
When I plug in any one of my 4 USB OTG cables, I get the following;
'USB Mass storage connected'
'USB mass storage unexpectedly removed'
Does anyone have any ideas why this might be happening? I was hoping to use my Note 2 as a portable media viewer for the photos/videos I take on my DSLR. Kind of frustrating ...
Does your device do this at all? Better still, if you have a demo version of the Note 2, does USB OTG work on your device?
Really hope someone can help,
Thanks

There is a fix for that in custom roms try wanam rom 2.8.
I think you may find the flashable mod somewhere in GS2 forum.

USB OTG works on my device but...
Without a power source I can only see USB sticks and SDCards.
If my hard drive enclosures have an external power source that I hook them up to, then they work too. It the drive is NTFS formated then you have to use Paragon exFAT, NTFS & HFS+ to see it.

Thanks very much for taking the time to reply. I actually ordered and replaced the usb connection port, yet the issue still remains. So I am quite sure it isn't a hardware fault. I'll try and find the mod you have mentioned ...
Just out of curiosity, is there anything else I can flash beyond the pit file, the kernel and the rom? My device is a 'demo' Note 2, so I am starting to think that maybe Samsung put some other firmware file on the device that tells it not to fully mount USB OTG devices (it'd make sense to do such a thing in order to stop customers in a shop loading up their software from a USB stick).

I bought it from a guy who was winding up his mobile phone shop business. He had 4 of these things. The mobile phone component doesn't work - but everything else does (apart from USB OTG on my device - v.v.frustrating!).
You can find them on Ebay by searching for N7100x or N7100 demo version.
If anyone else has a N7100x, please tell me if your USB OTG works.The Wanam rom fix is for wakelocks caused by disconnecting a USB OTG device --

I've tried everything I can think of to get this problem sorted. I am starting to think that it is a hardware issue relating to the fact that the 3G aerial that would normally be powered/connected to the USB connector board is not attached.
As such, the USB power being delivered to USB OTG devices is higher than normal (given that there is no 3G power drain)...so it perhaps overloads and disconnects connected devices.
I have replaced the USB connector board with a hardware revision 0.2 board (the one that came with the phone was a 0.7). I have installed the following files via Odin;
BOOTLOADER_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
CODE_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
CSC_XEF_N7100OXADLJ2_422394_REV00_user_low_ship.tar.md5
MODEM_N7100XXDLJ2_422394_REV00_user_low_ship.tar.md5
t03g_0907.pit
I don't think there are any other software partitions on the phone that can be overwritten (the phone is therefore 'stock' as far as could possibly be the case with a demo phone).
If you do find a solution, I would be most grateful to hear about it. This is my perfect device for video/picture editing & uploading to Youtube whilst cycle touring (I don't need the phone connectivity when abroad). Although I can work around the USB OTG limitation, it would be incredibly useful to have that functionality.
All the best,
Laurence

USB OTG Cable?

Firstly, is it worth getting a USB OTG cable? What can you use it for? Do you have one?
Second, which one should I get for the Galaxy Nexus? I've seen these two:

Which is better? Is there any difference? Appreciate the help.
Thanks,

First you have to get the app called Stick Mount if you want to use usb flash drives. But the OTG cable can be used for a lot of things, keyboard, mice,
usb flash drives. I've seen a youtube video where the guy uses a hub and uses all 3.

How much can you do using USB OTG with an unrooted Galaxy Nexus? Most importantly, can you use a memory card reader to copy files from the memory card to the phone or use it to upload the files to Dropbox?
I'm asking on behalf of my sister. I don't have access to her phone so I can't simply try it out. I know USB OTG works great on my rooted Galaxy SIII but I've never had a Nexus device.

As of 4.2 there is native support for USB OTG on the Galaxy Nexus so you don't need any third party app. You can use it without root USB device is mounted as /usbdisk. Try X-plore from the Play Store which shows a separate drive for the USB device you have connected.

See if there's an option in settings>storage as Mount USB storage, if not there use an app such as stick mount or USB OTG helper. Even for using those apps the phone should recognize when a storage device is connected, the pen drive/card reader should light up.
If option is there and still not mounting then any of your devices may be improper check your OTG cable with other phones, your pen drive/card reader.
Clean the contacts of cable and your USB device. Best way to confirm working is to boot to recovery and connect, USB storage is always mounted in recovery mode.

Any decent file explorer should also be able to see mounted storage, especially given 4.2. You may have to browse to root and poke around until you find the appropriate /mnt folder, but set a bookmark (your explorer supports bookmarks, right?) and that should be all she wrote. StickMount is also great for me.
OTG has been really helpful for playing media off of the occasional flash drive, and while using a mouse isn't all too helpful, playing with a full keyboard can make for a surprisingly good experience.
