Putting usb hub inside the TF

If you've ever opened up the TF, you'd very quickly realized that there's a lot of unused room in there. I found a 64gb flash drive from walmart for about $60 a piece. Got 3 of these. That gives me almost 200 GB.
I've been doodling with the idea of putting a usb hub inside the TF and then solder these flash drives onto it. Making room for the whole setup is no problem. Like I said, there's a lot of unused space in there. The problem is I don't know how to connect a usb hub inside there for the tablet to recognize it. Any idea guys?

i have a similar project in the works. i just wonder if we have a limit as to what size (storage) usb drive we use i want to try a usb powered 1tb hard drive...the possibilities would be endless.
one other idea i have no clue of how and if possible. but you know the EXT.(as internal) SD mod, what if we could find a way to do that with the usb storage.think of 1tb of storage("internally")!!!!!!

I've already done what you're talking about. I've already put 500gb, 750gb, and 1T HDD into the docking station while keeping the batteries.
What I'm talking about is putting flash drives inside the TF itself, not the dock.

yeh but im taking the dock apart and putting it inside like you are saying inside the tab that would better i think you idea is better.
i think both in conjunction would be insane!

Love the dock mod but the images isnt working in the thread
But getting the TF to recognize the usb hub should be that complicated.
You'd probably need the usb host adapter (or make one yourself, if possible, idk).
Then it should just be a matter of soldering the adapter to the correct pins on the docking connector.
You might need a switch of some sort to tell the TF when to be host and when to be slave.
I dont own the usb host adapter myself yet, so Im not sure how the TF acts with the adapter connected.
Maybe its still possible to charge and sync even though the adapter is connected.

Haha, we'll see.
I've figured out a way to solder in a usb board and connect a hub to it to add those 128gb flash drives. After spending all night going through the plans, I'm abandoning the thought of putting it into the TF itself. I'll be putting those flash drives into the keyboard dock, though. Solid state drives are certainly much better than the spin discs. Let's see, 128gb x 4 = 512gb of flash drive space... won't suck up my battery much and aren't prone to damage due to movement like the HDD.
Stay tuned for the result!

Man, you have balls modding out your dock like that I was impressed with your first dock mod of sticking that 500GB hard drive in it. Did you ever go back to that idea with doubling the battery life in the dock? I recall following that thread reading your updates and you got to a point where you said screw it.

Without people like me who like to push things to their limits, we'd still be writing with hammer and chisel on stone.

There's 2 questions that come to mind.
1) Will any of the USB ports support a USB hub? I seem to remember there being some issues with this, but I honestly can't remember anymore...
2) Will you lose the use of 1 of the USB ports on the tablet?
I'm inclined to say that most likely 2 will happen, unless you're very VERY good at modifying the boards and don't mind cutting trace, possibly. If I knew I could afford another keyboard dock, I'd be doing this right now. Sadly, I can't. =/
EDIT:Well, in a quick check with my ****ty USB hub, it didn't like any of my USB sticks, then saw 1 of them but none of the files on it, then just kept showing that 1 stick no matter what I put in it. I'm rebooting, but I'm kinda thinking it doesn't like the USB hub I have, or doesnt' support them?
EDIT2: Seems that it only lets me see 1 USB drive at a time. No matter what I did (outside of using the port on the other side). I kinda think either my USB Hub isn't working well (works fine on my PC) with the TF, or it just doesn't support it for some reason. Or more to the point, it seems it only supports 1 USB disk drive per USB port on the dock. If I put 1 drive in each port I get USBdisk1 and USBdisk2. Perhaps it's an OS issue or a TF issue in some way as far as software? One would think you could get more than 1 USB disk on each port though.

So true. And without Android...we would probably be using a single core under 1Ghz. I still remember people saying "why do you need that much power?" Then..."who needs dual cores"...now..."quad core? Forget about it!" Hahahaha

You really ought to read my hard mod thread. All of this has been discussed very thoroughly there. 2 Will happen. So what? There's 2 usb slots. Lose a usb slot to trade for 500gb storage space.
But that's why I put in a switch to turn on and off the hard drive. When the hard drive is off, the usb is usable.

I did read your thread...you probably don't remember me asking similar questions before
Honestly though, read the few edits I put above....I kinda think this won't work the way you want it to...seems to be some kind of strange software issue in regards to USBdisk's, for some reason.
EDIT:I guess it COULD work, if you could mount them somehow. I'm not sure how the addressing and such works, and honestly my linux knowledge isn't what it used to be. I guess what I'm saying is it could be done, I'm just not personally sure how in software. If you figure it out though, let me know. I'm sure I'd be interested.

Any chance you could reupload the images for your HDD mod?
Shame you abandoned the idea of putting the hub inside the TF, that wouldve been very interesting.

Cheap powered USB hub

Has anyone had luck with this one? I'm looking for one that is not too expensive.

That's not a "powered" hub. By most definitions, a powered hub would utilize a separate power source like an AC adapter, so the attached devices can draw power from it rather than the host device. Something like this perhaps...
http://www.amazon.com/dp/B000ERAOL4
I don't have any experience with either product... just wanted to point out the difference.

The Belkin looks like a good choice. There are cheaper products, but I suggest paying the extra bucks for something with a name brand and reputation.
I've had mixed results with cheaper powered hubs. Some worked fine, but none of them for long. My most common problem with cheap hubs is that the USB ports get loose and stop making good connections with your devices.
I've had another odd problem with one of the cheaper ones. The 5v input from the included transformer was not correctly isolated from the 5v of the USB port that heads to the PC. When my PC was shut down, other USB devices on my PC would try to power up through the tiny transformer, which eventually killed the transformer, and was also the most likely reason I had a set of USB ports fail on that machine.
Anyway, what I'm saying is that my recomendation is to buy from a company with a reputation to protect, it's worth the extra few bucks.

Can you still use USB 2.0 cable to charge Note 3?

http://www.theverge.com/2013/9/5/4696874/galaxy-note-3-usb-3-0-power-connector-explained
I have a lot of the USB 2.0 cables, does this mean I have to buy all new cables?

Yes you can. One side of the port can used with a standard Micro USB cable. The linked article even contains a note about it:
Although it's much wider than the Micro USB connector you're used to, the new port is actually backwards-compatible: a regular Micro USB cable can plug into one side of the port.

That actually works?
*goes to test on a USB 3 harddrive*
Bloody hell! It actually does! You can use a USB Micro cable on a USB3.0 port.

Can confirm the port works with regular micro USB (and Smart Dock, and regular USB OTG cables). Lucky enough to have played with a Note 3 for half the weekend just gone.

But you can't use a an apple 30 pin connector on a lightning port apple product, you have to spend $29 more per cable or risk damaging your device. Ah, the beauty and elegance of industry standards.

Good luck trying to stuff it in there to begin with.... :laugh: I have no trouble imagining the average iSheep attempting to do so and not comprehending the reason for their failure! :laugh:

Finally USB 3.0 speeds. A shame there isn't a 128GB version of the phone and/or 128GB microSD cards to really let these speeds matter.

Lenovo has lowered the price now to $379. I have asked if they will charge my card with the new price or if the old price stays..

Can you charge and mount USB at the same time with this thing?
The realization that there's only one USB port on this device made me wonder if it shared this limitation, and from what I've read, it does. Can anybody confirm this? I can't settle for rumors and stringing together nebulous conjectures. Once they appear in my local Best Buy/MicroCenter I'll be testing this myself, of course.
If anybody's got it, I'd really like to know that. That's kind of the deal-breaker for me. It was the biggest reason I didn't get the Venue 8 Pro (that, and lack of reliable video-out). I don't mind carrying a host cable around with me everywhere either, or the spare battery... or even a tiny USB hub. I just want to know that I can use USB and charge at the same time so I can have a very mobile "desktop" experience wherever I decide to bust out my tablet. No more damn Chromecast bugginess, no more damn finnicky MHL connectors.
I know that the Venue 8 Pro simply cannot do two at the same time; I tested this fact in the store by connecting a host cable, a power source (2.1amp rav power backup battery) and a USB thumb drive. Mounts just fine with a USB OTG cable, but will just not mount and charge at the same time.

Very few devices can. Most USB Hubs cannot backfeed power, so you cannot use USB host adapters to a powered USB hub to charge the tablet most of the time, regardless of if it actually supports charging while in host mode, there is a raspberry pi compatibility list which lists a few hubs which can or cannot backfeed power (the pi can be backpowered via its USB host ports but this is not recommended and can conflict with other inputs). Most tablets though require the D+ and D- wires in the USB connector to be shorted together to enter charging mode, otherwise they will only trickle charge (or not at all), with D+ and D- shorted you cannot transmit data. Turns it into a case of data or power only.
Frankly, you want the desktop experience, yet are purchasing something running 32 bit windows on an intel atom wih 2gb of RAM and either 32 or 64gb of eMMC storage. I think an i5 device would probably be more up your street, most of them have separate power supplies and USB host ports.

Hello again, did you receive the tablet on the 11th? Would love to hear some first impressions. I am in particular interested in finding out how the cover works as a stand and if you can have it standing both horizontally and in portrait.
Thanks

If you are referring to the thinkpad 2 10" tablet, that used a microUSB for charging and had a seperate full size USB host port (the micro USB was not host capable). The dell venue and lenovo thinkpad 8 both use microUSB for combined charge and host.
If the power and USB host ports are seperate then there is no issue. The issue arises when its a combined port which is what most of the atom tablets are opting for.

Played with mine on the weekend.
The cover works as a stand pretty well. As long as the surface inst too slippery you can put the stand on slightly different angles too.
It also is strong enough to work on vertical too.

What do you use it for? I'm considering selling my 8 inch LG G Pad for an 8 inch Windows 8 tab. I'm contemplating this or a refurbished Surface Pro for about the same price. Just wondering if Bay Trail is really a lot better than Clover trail. I had a ThinkPad Tablet 2 and it was God awful.

I got mine on the 11th. It's been fun ever since. I can't believe I like Win 8 as much as I do. I'm still looking for a BT keyboard and a case... Like always it's slim pickins...

USB 3.0

What's the deal w/ usb 3.0? Is it disabled? Can it be reenabled?
The board, supports it, and it seems counter productive to put a usb 2.0 in such fresh HW.

It sounds like that could be an issue. Also, USB 3.0 is so fast that it can outpace a lot of the flash memory in phones. So there would have to be faster memory in the phone to handle it and that raises costs.
I'm sure it's a cost issue in the end. And not enough people know about it or care. They may also not have computers with USB 3.0 connectors to appreciate the difference. So the group of people this benefits shrinks and shrinks, while the cost per phone remains the same.
Also, most companies and especially Google are trying to push people into the cloud, not into phone storage. All the better to track you with for advertising.
I'm sure eventually it or something else faster will be the standard. It is disappointing how long it's taking though. And it does seem dumb to put in a larger USB type C port (supposedly one of the downsides of USB 3.0), but not take advantage of it. I definitely get tired of how slow USB 2.0 is when backing up my phone to my computer.

USB 3.0 on type C doesn't support fast charging, I am 99% sure this was brought up in the reditt AMA and has been discussed on this board too.
Everyone is so up in arms over it not being 3.0, but most people don't even know the benefits of it, if you plan to transfer hundreds of gigs of data from your phone to your PC on a weekly basis, then I guess you need it, otherwise the main purpose of the port is to charge your phone, I'd rather have fast charging 2.0 than regular charging 3.0
