Hello everyone, Im not sure if this topic has been discuss in detail or not, but I have managed to connect a spare 500gb hard drive to my note 3. Here is everything I used.
I upgraded my laptop to a Samsung 250gb SSD, which provided me with a spare HDD:
http://www.amazon.com/Samsung-MZ-7T...=1387366438&sr=8-2&keywords=samsung+250gb+ssd
It comes with a cable already in it (USB 2.0) so this next item is optional, A Apricorn USB 3.0 Transger cable:
http://www.amazon.com/Apricorn-Note...qid=1387366498&sr=8-1&keywords=apricorn+clone
And lastly, it needs to connect to the phone, so I picked up this USB 3.0 OTG cable:
http://www.amazon.com/White-Color-M...7366411&sr=8-3&keywords=galaxy+note+3+usb+otg
Now here is the steps I took.
Since my HDD still had stuff on it, and it was partitioned, I had to wipe it clean. I formatted the HDD on my computer first. I formatted it to exfat. Maybe another way will work but I'm not testing it. I then hooked up all the wires accordingly and plugged it into my phone. The N3 did not recognize the file format of the HDD so I re-formatted it to the N3 standard. After that, it is as simple as plug and play. I was even able to use the stock My Files app.
Note*** obviously the SSD is not a requirement, unfortunately, I am unable to test it as it has been in my computer for several months and I dont want to risk corrupting anything. It may work with the SSD as well, although I doubt it will reach the speeds it can on a computer.
I am not rooted and did not have to download anything extra for it.

Cool. But curious as to why you would need a 500G HDD attached to the N3

This. We were using a variant setup, pushing the content via DLNA to our Xbox 360 (connected to a good ole 'dumb' tube TV). Quite enjoyable.
Damn I didnt even know you could do this
Has anyone found a way to pass through power with a splitter or something so while connecting the USB OTG cable you could still run the phone off of power without depleting the battery? I asked this same question in the Note 8 forum but no one found a way.

I'm sure it can be done. That would be ideal. I have the 10,000mah zero Lemmon battery set to notify me when it's available again. I'll look around for a spilter

what format was the hdd in exFAT or NTFS ?
I use the OTG dongle to hook up my 1TB drive and play movies and TV shows directly from the drive.
(Also works with the tablet)
I formatted it to exfat. I have a 1tb external also. But it's already formatted to ntfs. And it's full so I'm not going to risk losing a thing on it.

Because it's not supposed to work that way... The OTG cable puts your device in "host" mode... so it will use the phones power to run your HDD and kill the ability to charge... there are ways to get power to the HDD so you don't drain your device battery as much but the charging thing is a native function of OTG switching.
This is what i've been using... it has HDMI out ... microUSB 5v input to run the HDD... USB port for HDD or any other USB device... (using a wireless keyboard on it right now)... and card reader ports...
You can fake this thing into trying to charge the phone by plugging in the micro USB connection first and THEN plugging the hub into the phone with the microUSB power already on... then you see the charge notification in the status bar but it still doesn't charge the device... even with the samsung 2amp charger as a power supply... the battery still drains
What about wireless charging? I Don't have a wireless charger or battery cover to test this. But this may work

That actually is a good idea to try. I'm less optimistic about that as my previous experience with wireless charging has shown that it is less efficient t getting current to the phone as a wired connection and there are some things done on your phone that even when plugged to a 2A wired connection will still drain the battery.
What about the Smart dock? With 2 USB ports an HDMI and power in?

That's the problem I'm running into... I'm running the HDMI/MHL/OTG hub... I got the HDMI out to my flat screen... OTG to a wireless keyboard... bluetooth mouse... When it all hooks up properly (you have to plug everything in the right order) the Note 3 screen shuts off and it runs as a proper CPU with output to the flat screen...but even with the samsung 2 amp charger plugged in I still lose about 1% battery every 5 minutes... better than running without the charger but that s$#t can't be good for the battery running that hard and charging at the same time AND losing the battle.

OnLive recently came to Android and a number of games require a controller. I tested OnLive and it ran fine, I just need a controller.
Is there any way to use a USB/etc controller on a NT? Or like the Sixaxis or 360 controller.
Without bluetooth (which the nook tablet doesn't offer) using a wireless controller is gonna be difficult.
Maybe a wired one might work but I'm not sure if you're gonna find one that will connect to the nook tablet.
Gotta say though, I've tried some of the on live games that work without the controller and they play really well. If there IS a way to add a controller- this could really step up tablet gaming quite a bit.
How about a keyboard? Is it possible to hook up a keyboard to the NT?

Yes, technically. You need a custom rom installed though with bluetooth activated. But even then the range is very small. But ive never needed to use a keyboard from far away with my nook. Also, some work better than others. Hope this helps.
I really want to plug a keyboard to NT after I installed Quake 1,2,3. It's so smooth but I can never play it!! Like standing in front of a game shop
I thought ROM edits were locked on the NT? Or something was still locked.
But you can enable Bluetooth on the NT? I hadn't heard about that.

While there appears to be a Bluetooth capable chip in the NT, it has yet to be determined whether or not we will be able to enable it -- with or without custom kernals.

Gingerbread has USB host mode but the ROM has to enable it. I have a mini USB to female USB coming. I will check keyboard, mouse and sixaxis support when it does.

As some of you know, I could get USB host to work on the release candidate of HoneyComb but not on the final release (3.55.405).
This morning I thought I would try again, my flyer was turned off (completely shut down) when I plugged in my portable hard drive (Seagate 120 gig using the Y cable one to a power supply the other to a USB micro USB adaptor).
I then booted up the Flyer … low and behold there it was. Shows up as USB in Astro but, does not show in Root Explorer.
I was able to watch my movies and play my music from the hard drive.
It seems like the flyer with latest HoneyComb will only see USB peripherals at boot time.
Great news!
If you care to try some other configurations, I'd love to get your results when using a usb keyboard or mouse?

It works perfectly fine without rebooting. The only thing is that you have to umnount before unplugging. It worked for me even with one 1TB Harddisc.

I don´t use a custom rom I use the HC stock rom. You have to have the "/mnt/sdcard/usb/" folder. If you don´t have it, create it. I use only as I mentioned a 1 TB Harddisk and I used also two different kind of 8GB USB Flashdrives with a Y-Cable with external powersupply and a Nokia OTG Cable.
They work all perfectly fine. Only I had to unmount the devices before I unplugged otherwise I needed to reboot as well for a another usb device.
I didn´t try any other peripherals.
I am not a "tecfreak", just an average user who likes to tinker and mess around with his gadgets. If you have any further question I can help you with, Please ask.
P.S.: before I used the Nokia Cable, I used another Micro USB Male to USB A Female Cable and that didn´t work, so If it doesn´t work for you than it might be caused by the wrong cable. ????

Been doing some more testing … I noticed (when using the Y cable on my drive) that when I power up the hard drive the charging light on the Flyer comes on.
So, somehow power is back feeding to the OTG cable.
This leads me to believe that it may work better (like Elfuente stated) with a different cable.
Perhaps the Nokia cable does not have the charging pins
Ps: I noticed that on my Y cable … one is labeled Power+Data the other is labeled Power

Ahhh there you are I was hoping you would show up. If anyone could shed some light on this it would be you. Do I smell another hardware hack?
Keeping in mind my abilities in this field are very limited but, I was thinking … if I could come up with a battery pack for a portable hard drive I could (with the proper cables) then just plug it in and have the ability to read and write to it.
Maybe another hack for an adapter to provide power from a battery with usb connector or mains usb charger but it should actually be fairly trivial to implement, so maybe a schematic also for anyone who is remotely comfortable with soldering.
The big difference between OTG and other usb modes is that pin 5 is electrically significant. When grounded it indicates to an otg capable device that it should go to OTG-A mode (OTG equivalent of host mode), when floating it's ignored and the device will not detect a connected device.

I’ll then take both apart (drive and battery) and mill up a case to mount both of them in.

I made a USB dongle that plugs into the USB port on the touchpad and provides a powered female USB-A port. It is basically a portable USB charger/battery with an OTG cable soldered to the USB port. Attached is a quick pdf showing the process. It's much smaller and more portable than using a y-cable and powered hub or battery pack.
The charger is $13 on Amazon with free prime shipping and OTG cables around $2 on ebay.
It's nice because it's small and I can secure it to the my case with a rubber band, providing a quick connection to a keyboard/mouse or usb flash drive. The particular charger charges via any powered USB port with a provided cable.
This is the battery pack I ordered, note the picture on the amazon page is not 100% accurate:

This hub has 4 ports, a battery plus solar charging. That said, if I buy it I'll probably just plug it directly into the OTG cable rather than solder them together. Then again my soldering can be a little rough.

Deserves sticky, love mods like this even if not always practical.
Cant believe they didnt give the touchpad a powered usb host. I guess they figured people would have issues with not enough power or drain the battery too quick with it.
So I think when I have some spare time I may mod your mod and show how to make a powered usb host that plugs into the wall charger so when your "docking" somewhere to charge you can hook up a keyboard and use it without restriction and even be charging the touchpad at the same time.
Probably don't even need to be too creative a proper Y cable may do the trick out the gate. Just to track one down.
Probably a stupid question, but it wouldn't be my first one...
Could you simply use a USB male-to-male cable to go between the battery pack and the OTG cable? Eliminate the soldering that way?
Or am I missing something?
I found a cable that I think will work perfectly for my idea of doing this from the charger instead of from battery: http://www.dealextreme.com/p/usb-fe...gb-tf-card-card-reader-kit-for-xtc-clip-82289
You can do it much cheaper with adapters and a regular y adapter though, and you may want to do so, so that you can have a longer cable from the charger to the y split, but yeah I will try this out sometime soon and let you know how it works.
The charger probably gives enough power to easily run things like a external HDD and such while the battery pack may not.
@Vicious ... couldn't that possibly put too much power to a USB device? Just saying since it is probably meant to be hooked up to a regular USB 5v port and (I don't know the specifics but) the touchpad USB power adapter has a high AMP output (might be talking sht here).
Nothing to worry about a device only "pulls" the amperage it needs so you can have extra with no harm to the device. It is the voltage that needs to match and usb is standard 5v.
Having too little amperage can actually cause a device harm due to malfunction, like a head crashing on a 2.5" hdd during use or a thumb drive failing to flash properly corrupting a sector.
I feel anybody that uses the touchpad in a docked setting that wants to use a keyboard may very well make use of my idea, that I of course got from the OP's idea.
I'll part it out for the cheapest way to make it without any cutting/soldering and test it soon enough.

That cable will work fine. I wasn't doing anything special, only eliminating the y-cable. I mainly wanted a small form factor way of adding a USB port to my case for portability. Now I can put a movie on a usb drive and watch it on the go.
You generally don't have to worry about using a supply that is to powerful. As long as the voltage output is 5 V, the device will only draw a certain current and consume the corresponding amount of power. The rating on a constant voltage supply is simply the maximum current it can provide, the amount it provides depends on the properties of the device.
Say you have a device, it states it operates at 5 V and draws 100 mA of current. That means the impedance of the device is R = V / I = 50 ohms. So if you use a 5 V supply rated to at least 100 mA, the device will only draw 100 mA. The supply can be rated for 100 mA or 1000 amps, it does not matter. (Although you wouldn't want to use 1000 A source as if something breaks or shorts it can draw a higher current)
Wikipedia "ohms law" if you are not familiar.
I tried to do this but can't get it to work, the touchpad shows the charging battery icon only it's not charging, and running dmesg it say source=charger mA=100 and usb otg exited low power mode and then right after says it entered low power mode... Not sure what the issue is...

You may have the two data pins shorted together. To the best of my knowledge, this tells the touchpad to go into charging mode. The touchpad charger does this, because in order to charge, it must draw more power than USB ports are designed to provide.
You need to remove the two resistors circled in the PDF. These keep the data pins shorted together as well.
This is a really great idea I think I might try it and your tut is very well explained thanks for taking the time out to put it all together
Thanks
Mouse works fine, keyboard hasn't been tried yet. How do you access a flash drive through this? What are the steps?
If you just cut out the resistors in the battery hub, could you just use the TP's regular cable to plug into one of the ports on the hub?

just ordered one on ebay (only an adapter from normal usb to micro-usb) for 1$.
Along with the otg cable u also need a usb Wye cable...the need is to provide power (plugged into the wall) for the usb hub (which u will also need ). Not Neuf power and the drives will not mount. Getting a solar powered usb hub cuts away the cables and detached u from the wall...I got mine on Amazon for bout 20 $. Totally worth it.

-USB keyboards and mice work fine including all basic functions like scroll wheel on the mouse, num and caps lock on the keyboard.
-FAT32 formatted flash drives will mount by default under "/mnt/usbdisk".

-If you want to mount NTFS drives or multiple flash drives, download Drive Mount. This software will mount drives under "/mnt/sda1", "/mnt/sdb1", etc. I can confirm it works for multiple drives and NTFS/FAT32. It was removed from Google Play so the apk has been posted. If anybody has had success with other NTFS mounting software please post your results.

-I tried a Rosewill USB SATA/IDE externally powered hard drive reader and was able to mount a 400GB SATA 3.5" HDD using Drive Mount. Just to see what would happen I tried a SATA DVD drive but Android doesn't recognize it and probably doesn't even support the CD/DVD file system.

-USB card readers will work, but I've had mixed results.
USB Device Info:
If you want to diagnose items and see some info about what the Touchpad is detecting, download USB Device Info free from Google Play. Everything shows up under the Linux tab. This shows some useful info about devices including current draw, device identification, etc. I tested it with a USB hub and a few flash drives and it successfully showed entries for the hub and the flash drives. It wont tell you if Android has drivers for the device, but merely IDs the device(s) confirming the connection if working.

A plugged in USB OTG adapter will show up as "Qualcomm On-Chip EHCI Host Controller" under the Linux tab regardless of whether or not power is present. This is a good way to see if you have a working OTG adapter.
Flash Drive Unmounting Issues:
Flash drives are called an SD Card when mounted. There is no option to unmount a flash drive unless you use Drive Mount, so if you notice SD card removal error messages they are referring to your flash drive and not the Touchpad's internal memory partition that is mounted as /sdcard.
When a flash drive is removed or powered off without being unmounted, its common to get a "android.process.media" force close, just tap OK.
Charging:
You will not be able to charge via micro USB while using OTG even if your power source has enough current. You can charge via the Touchstone just fine. Knowing this, you can set up a really nice docking station by using the Touchstone as a stand/charger and then using the microUSB slot for peripherals like a USB keyboard and mouse connected to a hub with spare ports for flash drives, etc.

Insufficient Available Bus Power Fix:
If you get this error, I haven't yet, some users have had success using this app posted on Rootzwiki.
I didn't feel like buying anything and already had some things laying around so I modified an Adafruit MintyBoost to accept a device via usb, add power, and continue on down the line...
Really all I did was solder a usb cable onto the female USB port on the MintyBoost, drill a hole on the other side of the tin and feed it out. The card reader conveniently fits inside of the mint tin so it's a pretty compact package.
The only down side I've noticed is that it also charges the TouchPad (the batteries will die quicker) and continues to send power to the card reader after the OTG cable has been unplugged from the TouchPad.
Excuse the crappy pic. I really don't feel like taking a better one.
I could never get the OTG cable to charge the Touchpad, I always thought when the Touchpad sensed OTG (grounding on pin 4) it refused to take power. You can disconnect the +5v Vcc to the Touchpad (red wire) on your OTG cable and OTG devices will still work.

I came to the same conclusion some days ago ,touch pad can't be charged using org cable,needs a regular micro USB cable and the barrel AC charger.I did many tests but having otg devices working and really charge at the same time its not possible,it seems like charging but its not.
Today I accidentally found this http://direct.sanwa.co.jp/ItemPage/400-GADR002W that by first look it could be awesome...
Edit:a mini review in english http://www.gadget.pdamu.com/2012/03...r-dock-station-for-android-smartphone-tablet/
says that it can be also powered be micro usb charger....
Bummer. Tried linking my phone evo3d, but no luck.

If its provides its own 5v power it would likely work, but I don't really see anywhere for an external power connection and it looks too small to house a battery.

For whatever reason, when I tried that the card reader wouldn't initialize. Once I connected the +5v from the OTG it'd light right up...
After it lit up I could disconnect the +5v and it'd stop the "charging" notification on the touchpad and keep working.

Then it should work fine as the Touchpad uses a standard OTG pinout, it just doesn't provide power so if it has a way to provide power to devices than I see no reason why it wouldn't work.
quick question that i didn't see answered above :S can i use the otg cable adapter without another power source (like can touchpad power it?)? Saw it asked above but didn't see anyone saying that the power source is required :S
kind of want to plug a usb flash drive into touchpad so I can type documents when I'm on the go and switch to computer. don't want to carry another power source either :S

No, the Touchpad doesn't provide any power for OTG devices which is why you need to supply it power. The cheap USB charger I linked to in the original post will work fine for a portable power supply if you don't want to build something yourself.
And it also appears you can't just plug the other USB into the wall?

can someone get a group buy going for these???

So, we can't just plug it into a wall for power? I have to buy a battery powered unit or use a powered hub?

Nice and cheap and the best part it works.
USB Hub works...sort of.
I tried this with a cheap USB hub I bought. I had bought it for my laptop and made sure it had it's own power supply to keep the load off my laptop, so I thought it would be perfect for this. Nice try though.
Turns out it needs 5V from the host to activate as well as the additional external power supply. Just fired it up with my TouchPad connected via a Y-Cable and my Laptop providing the 5V to fire it up. Works like a charm.
As yet to find out if it works with my travel charger providing the 5V and no external power supply plugged in, and how many devices I can hook up. It's got 7 ports so I suppose the supply might be useful then, but do I really need to hook up that many devices? Otherwise...pointless. Back to the drawing board I go.

This would be really handy and it's a much more elegant solution than a y cable and external power source.
Too bad it seems like we won't be able to get one easily.
Am i missing something here or can i use my 3.5" external HDD (with a power supply) to provide power to my External so i dont have to plug the cable into a USB hub?

You should, I did this on my Touchpad running CM7. Haven't tried since going to CM9.
