[Q] Tab 10.1 with USB hub via USB adapter?

Hey,
Does anyone here have the USB adapter for their Samsung Tab 10.1? Can you connect a USB hub to it (maybe a powered USB hub)?
I take lots of full resolution photos, and would like to use the Tab to transfer data from SD card to portable USB hard drive.
What I want to avoid is having to first copy the SD card contents to the Tablet, then connect the tablet to the portable HD to unload the photos. That seems like unnecessary wear/tear on the flash memory.
If the USB host on the Tab 10.1 can handle a hub, then I can connect both the SD card and portable HD at the same time...hopefully the Tab would make use of it's RAM (the 1GB spec) to transfer chunks of data at a time, without resorting to using the internal Flash memory.
Am I right about that? The Android OS doesn't use the flash memory as a page file for working memory the way desktop computers do with drives?

bump - hoping someone can answer. Thanks.

There is a thread in development about a homemade usb adapter, and it works successfully with a hub. The samsung adapter isn't available yet, but should work the same

pokey9000 figured out how to force the unit in host mode. All you need to do is put 20ohms of resistance (easiest way with two 10Ohm resisters in series) between pins 13 and 15.
He also tested using a powered hub and was able to connect to multiple items at once. A regular hub might work for a few thing that are low powered but if you plan to have two hard drives, it better be powered.

has anyone found a usb to sd card adapter for multiple sd cards?

Did you ever figure this out? I want to do the same thing.

New USB Adapter! Need help.

I just got the usb adapter and it work fine with a mouse or keyboard. The problem is I didn’t get it for that. I got it to plug in an external usb drive and for that it is useless. I have tried no less than five different usb drives and the tab sees them as a usb drive but I can’t read or write to them. They are all Fat 32 and under 32gb. WHAT AM I DOING WRONG? Or is there something wrong with the adapter?
Thanks.

I'm able to transfer files with no issues at the moment.
I had success by using a file manager app I got from the market, then navigate to /usbStorage/sda

Make sure to be working in sd card usb area because if you look in the regular usb area it does not show up

If the drive is a spinning harddrive you need to use a powered hub. Plug the external drive into the powered hub, then plug the hub into the usb adapter. Then plug the adapter into the tablet. I hope this helps you.

You rock man. That was what i was doing. Looked under sd/usb and there were my files!
Thank you.

external hard drive?

Hi people,
I read in a review that you can connect an external hard drive to the nexus 7 (the usb powered ones) via a USB Host Cable.
Could any of you tell me if this is correct or not? As i have an Archos 80 g9 and i know it cant do it off the micro usb only the USB 2.0 slot it has.
Thanks a lot for the help

Yes, it is possible but you may need to provide external power to the drive. Use a powered usb hub or something like that. The Nexus 7 most likely won't be able to output enough current to power a spinning drive.

Ah ok, so you are saying that you plug the usb host connection from the nexus to the usb hub and plug the hard drive in to another port on the hub?
I just want to know if this works as 16GB isnt much space when you want to take it on a trap to watch films.
cheers

you need to be rooted. my understanding is flash drives or micro sdcards are good to go, not sure an external hd will work unless powered as previous poster alluded

Since N7's have been out for a few days, has anyone tried hooking up a portable hdd using a micro otg cable? I could plug my portable Toshiba hdd into my Acer A500 tablet without rooting and it would read the contents of the drive just fine. I would watch movies and view pictures as if it were an sd card. Wondered if the N7 unrooted could do the same?

No it does not mount the external storage nor does it have an option to do so. You need to root and install chainfire's stickmount app for this to work.

Hi. I decided to use a wireless drive to store all of my music, movies and documents. So, I purchased the Seagate GoFlex Satellite Mobile Wireless Storage. You can use with Android or IOS devices. I love it.

Yes, its a no-go out-of-the box connecting to a USB thumb drive or a powered HD with a microUSB OTG cable. This doesn't really surprise me, though, because they would need to dynamically detect the device type and mount it on the system. What I haven't tried is a USB keyboard. Anybody do that?

yes could u test it out? i was thinking of buying a portable hard drive but not sure if it will have enough power to use it
does usb 3.0 work? or do i need to buy a usb 2.0

I've tested mine with an old 60GB WD Passport and a new 500GB Freecom XXS. Both are 2.5" USB powered external HDDs, and both worked fine.

great thanks for the info. btw is the new one using usb 3.0 or 2.0? do u know if usb 3.0 will work?

I just plugged in a full-sized USB keyboard using my OTG cable and it works fine. I can touch type, use the cursor keys including ctrl+arrows to skip words, bring up menus with the context menu key just to the left of the right-hand ctrl key, etc, etc. I'm sure it must be using up my battery at a faster rate, though.
Edit: It's just occurred to me that there's a problem with using a USB keyboard to type when the N7 is in portrait mode: finding a stand to hold the tablet upright at the right angle when the USB-OTG cable is sticking out of the USB port at the bottom of the tablet.
Mind you, it's great being able to type at full speed without a soft keyboard hiding a large chunk of the screen.

You can get OTG cables with a right angled micro-USB plug on them, which might help your stand problem. I have one on its way as I was concerned about knocking/bending/snapping the straight plug when its sat on my lap in portrait mode.

Or, just turn the tablet upside down so the cable is pointing up. The display will rotate appropriately.

I think but not sure that you'll want cm10 for the rotate from any angle thing...

how did you manage it ??did you use nexus media importer

Without a custom kernel, the external hdd won't work with Stickmount or NMI if it is formatted NTFS. I haven't actually used NMI, but others have posted about the NTFS issue.

OTG question

I have 2 otg cables one for my nexus 7 one for my S3 both cables work in both devices and i have a male to male usb cable, question is how can i get them to see each other so i can do direct transfer instead of using a usb drive or computer?? Can it be done??
Sent from my Nexus 7 using Tapatalk 2

First, have you tried to transfer content wirelessly between the two devices? That would bypass the need to use cables. You can use app's like ES File Explorer on the Nexus 7 to access other devices on the local network. Not familiar with the S3, but if it can access the wireless network its possible there may be settings to allow one to access the S3 from other wireless devices.
Second, to connect the two devices together via their respective USB-OTG cables you would most likely need to have a male type A to male type A USB adapter. Here is one example. The next problem is going to be how each device see's the other once connected. With some cell phones one has to put them into USB mode so other devices will see and mount the cell phone's storage.

Wireless works fine, just wanted to see if it could be done via cable also ive got the right cables they just dont see each other, unplug it n connect a flash drive and see's it so im guessing its not going to be simple.

On my non smart phone I have to put the phone into USB Mass Storage mode for the PC or my Nexus 7 to view and mount the storage space.
If your using a Samsung Galaxy S3, it may not support mass storage mode. But there is an app called USB Mass Storage APK, creates by a XDA Developed that may work. See this link for more info...

Now that looks like the kind of app i need on my S3 thank you very much.... I best go and root my S3 again lol.

I'm thinking you would only want to use one OTG adapter when doing this. You want one of the devices to be the flash drive for the other. The one that will be controlling the session gets an OTG adapter and you connect the second device using a normal USB-to-MicroUSB cable. From the second device's perspective, it is being attached to a PC.

I use stickmount on my rooted N7 and put my HTC Sensation into USB storage mode. Then the N7 sees the HTC as a mounted folder.
I use a OTG lead in the N7 and a standard A to micro-B lead from that to the HTC.
I haven't used it the other way around, as the N7 doesn't have a Mass Storage mode.

USB OTG a few things tested...

I've no idea if this will be of interest to any of you, especially those people who have yet to buy a 5t and are trying weigh up the pros and cons, but USB OTG is something I use all the time, so o it was one of the first things I tested when I got mine. So far I'm really pleased as everything I wanted to work does so. My last device, a Xiaomi Redmi Note 2, had very poor USB OTG implementation so this is great from my point of view. Maybe I'm behind the times and I had the last phone on the planet with that problem - if so, please delete this mods
First off, before you can use USB OTG, you need to head into settings, then advanced and check the OTG setting. It turns off after ten minutes so I created a link on my homepage using Nova launcher's activity widget menu.
*EDIT* As ny-hardcore has kindly pointed out below, you can also have an OTG quick toggle in notification area. This didn't work for me at first (or I was hitting the wrong thing), but now it does .
Tested and working:
USB card readers of various types, including micro USB readers, with the help of a USB C to Micro USB adapter (5 for £4 on eBay!). The only one that didn't work is a proprietary Samsung multi card reader that also has a full sized USB output and HDMI out too. This isn't very surprising of course, but they're to be avoided if you see one on eBay and assume it's a generic adapter.
80 GB iPod hard drive in a cheap enclosure bought via Amazon.
1 TB 2.5" Western Digital HDD - that's right, no USB hub required, just plug it straight in. The only other portable device I've owned could power it was a Samsung tablet.
2 mega pixel boroscope (using USB Camera app in Play Store) . So useful for finding slow water leaks under the floor or peering down a spark plug hole into a cylinder!!
Micro USB DVB TV dongle, via adapter.
Keyboards and mice via an OTG adapter, including a combination media keyboard with built in trackball mouse (this usually doesn't work on my phones for some reason). The UK keyboard layout is supported via settings so you can have a £ key - woohoo!
Other phones! I plugged my old phone in and discovered I could mount it in MTP mode and then browse its contents from the built in file explorer. For what it's worth, the Oneplus even charges the device that's connected to it.
When you need to eject the device there's a button that appears in the notification area. Sometimes this gets obscured, so swipe down a second time and the 'eject' will appear.
I haven't tried any game controllers yet, but so far the support has been so comprehensive I don't see why there would be a problem.
In the attached photo, the only thing that doesn't work is the black coloured multi purpose card reader on the far right.

In quick toggles you can add an otg switch.
You don't have to go in settings that way to enable otg.

Thanks, for some reason that just didn't work for me unless I went into settings/advanced as well. I can't recall which firmware I was on at the time and I haven't tried since The quick toggles are so far away for my little hands too (please Oneplus add a Xiaomi one handed mode - in fact, make it EXACTLY like Xiaomi devices).
LOL, typical, now it does work for me! I was probably pressing flight mode by mistake or something.

Just FYI, I've tried the following USB DACs with an OTG cable on my 5T and they appear to work:
- Fiio E17
- Meridian Explorer (v1)
- Audioquest Dragonfly (v1)

I just discovered my old Saitek X35/X36 throttle/joystick combo works too! That's a first for one of my Android devices too. Now I need something fun to test it with

Has anyone gotten USB sound cards to work *for recording*.
Like I have a Terratec Aureon USB MkII and would like to livestream my DJ sets to Facebook via the FB app, by hooking up the line-out on my decks to the line-in on a soundcard hooked up to my phone and have the streamed video use the soundcard instead of the internal mic which sounds rubbish.
Edit: Tried it, and yes it works, but you have to hook up to the mic port, not the line in, and this doesn't seem like a great idea. Any idea how to change it?
Edit2: Scratch that, phone rebooted itself during a longer test

That would be so cool if you can get it working. Wonder if it's the phone or the Terratec? I have NO experience in that area. Good luck! How much power does it draw? Would a powered USB hub in the mix help?

Hadn't thoughtof the power draw issue.
What I really need is a super cheap low power USB line-in of some sort. Though after further testing, FB live streaming is crap, with low quality audio and video in all the configurations I tried (Android app, Win10+Firefox, Win10 app) so I'm probably going to abandon this plan and try a different platform like Youtube or something.

Just cant get otg to work in my device, I am on OOS 4.7.5, rooted with SuperSu, tried a type c to micro USB adapter, also a type c to USB 3.0 adapter, I have enabled the otg option in advanced settings before plugging in the devices, I don't know whether its the phone or the adapter I use, what kind of adapter did you buy, is it a type c 3.1 to micro USB 2.0/ USB 3.0, could you provide me with a name of the adapter.

I have the following USB OTG adapters.
2 X micro USB to full sized USB (the long type with a two inch cable).
1 X mini micro USB adapter that is tiny.
1 X micro USB adapter (bigger than above)
1 X USB C OTG adapter with micro SD card reader built in.
All of the above work. In the case of the micro USB OTG adapters, I'm using a USB C to Micro USB adapter (they're tiny, about 2 CM long).
In short, every USB OTG adapter I've put in it works. All are unbranded, generic adapters that I've bought from Amazon or eBay. I've never had to do anything more than enable OTG in settings.
Could it be something to do with the ROM you're using?
In the attached photo, the ones with a yellow Mark are micro USB OTG adapters. The one with a red mark is a USB C multi card reader (built in USB OTG). The one with a blue mark is a USB C to Micro USB adapter.

Sadly what you're doing is way beyond anything I've tried. I'm happy when I can get card readers and stuff to work
I vaguely recall reading about specifications for the older micro USB ports on phones and what type of power output they supported - not all were equal. For example, there were a bunch of Samsung phones and tablets that could power hard drives without needing a powered USB hub inline. Similarly, some could power an MHL connection to a TV without the adapter being plugged into a charger like most phones that supported MHL had to. I've forgotten the name for these specs, but presumably USB C is exactly the same and it'll be online somewhere. No idea what your Terratec draws or if that could be the problem - if our phones can spin a 1 TB hard drive then perhaps it's not an issue, I was just clutching at straws.
Good luck!

4.7.4 Stock. Stock recovery too (not rooted either).
USB OTG worked on stock 4.7.2 as well.

Working fine for me, stock, custom roms etc. Use a cableconnection usb/otg cable 6" in length. Just enable OTG in the swipe down, plus USB stick in...no problems.

I gave up on using the phone for this because the audio quality via the FB app is terrible anyway, so I nicked my GF's Windows laptop and started using OBS for streaming instead.
Power aside, it's awesome that an external sound card will work (kinda) for recording though!.

Thanks for the reply, I am beginning to think that it kind of an issue with OOS 4.7.5, I have to flash the old version and try my luck on it.
