I know there was a lot of confusion when details were first released on multiple sites including engadget but it looks like the USB adapter will work for the 10.1 check there web site for details. they are out and for sale.
on the bottom of the page it says goes great with.. and youll see all 10.1 devices

I think the confusion was with the SD adapter. It said "8.9 only" on Samsung CTIA slide. Hopefully they'll have one.
Anyone else think it's a bit of a con to release these all as separate adapters (i.e. if you want HDMI then that's an adapter, USB is another adapter, SD card slot is another adapter). I think Samsung could have put all those connections into a single adapter. Also, it's weird how the HDMi adapter has a little bit of cable to give some flex in the connection where as the USB adapter is just a single block.

Considering how big these adapters are, shame they couldn't put USB and SD or USB and HDMI or all three on a single adapter.
Even the media port doesn't appear to have HDMI out it, looks like it has another 30 pin port on the back and you have to buy the HDMI adapter for that.
All these adapters, all being sold separately is gonna get quite pricey too. Even Apple was compassionate enough to sell the USB and SD adapter in a single kit for $30 (saving $10 over buying each separately for $20).
PS. Though I imagine some third party might save us and come up with some adapter that combines multiple things together. They've done it with the iPad adapters.
Ugh these accessories are such a rip off. $19.99 for the damned additional data cable?! The hdmi cable port is also $29.99, just absolutely ridiculous. I'll prob eventually snag one regardless... :-/

Most definitely. This tablet is going to have so much aftermarket accessory support, we won't know where to begin.

With the exception of jump drives, most USB devices have their own cable.
Does anyone know if the HDMI converter works with the 7" Tab?
You guys are lucky to see accessories, the UK mob don't even have a clue about the 10.1
$40 for HDMI!?! Are they ****ing serious?! Who do they think they are? Apple?!
A bit more on this....

Can anyone confirm that the Universal does not have USB host. Most places just say no but there isn't really any hard evidence of it. I know the processor supports it but did they put in the necessary circuitry for it? Whats strange is that the Universal's miniUSB port is the same as my Sharp Zaurus's miniUSB port and my USB host adapter fits in. Does not fit into normal miniUSB ports. Just the Zaurus which had USB host and the HTC Universal. Just seemed a bit odd to me. I tried it of course and did not do anything.
I'll experiment with this further and check that image of the mainboard closely.
everybody who posted about it in this forum reported it to not support host
connector means nothing all htc devices since the universal have had the same connector
heck these days they are talking about making it the std connector for all phones nokia and the likes too
This all hinges on the connector, and the hardware used to drive the connector. The Universal(and indedd, all mobile devices) use mini-USB connectors, which do NOT incorporate a host control circuit. This means that, since USB uses a protocol that might be termed as "Speak when spoken to", your device can answer the computer when it asks, it can NOT ask another device to speak to it.
To sum it up, you can't connect a pendrive to your PDA, but you can connect it to your computer, precisely because of the lack of the USB host controller unit.
Hope this cleared it up for you...
Cheers
This is not what I meant. I'm talking about a specific type of miniUSB connector.
And in the recent announcement to make a standard cell phone connector, they chose microUSB.
This is what I mean.

HTC Universal's miniUSB port.
A normal miniUSB port.
My miniUSB -> USB host adapter from my Sharp Zaurus fits into only the Zaurus and the HTC Universal. Doesn't do anything in the HTC Universal though.
Not possible.
If you check on the internals, you will find that there is no power output to the usb port in anyway. so, its a hardware limitation and there is no way it will support hosting, be rest assured!

I found a thread in the German PPCWelt.info forum where several people say that there MDA Pro supported USB host, with a special driver:
http://www.ppc-welt.info/community/showthread.php?t=74113&highlight=mda+pro+usb+host
I don't know how reliable this is (not every USB client can act as a USB host because of different hardware AND software), but perhaps you want to try it.
Alex
EDIT: They also say that your USB device needs a power supply because the MDA can't do that (external hub). Other people even say that without such a power supply your MDA could be damaged. This Engadget article is also mentioned:

I know that. I just wanted to know if the hardware was there for it thats all.
the hardware maybe there deep inside the cpu but the pcb lanes where maybe support chips were never connected rendering it absent
can some of german guys test it and report it to this thread.?>
Is it possible to use this cheap 5-pin Micro-USB, type B - male to 4 pin USB typ A - female adapter to plug in a usb-keyboard to the note?
Or is it something special about these OTG-cables?
Please see the attached file.

I have tried a simple adaptor and it did not work - there are very similar looking adaptors that are OTG though.
Personally, I prefer to use a mini Bluetooth keyboard with integral "mouse" touchpad or an OTG cable to connect a similar USB keyboard rather than an OTG adaptor as I worry that I may lever the adaptor by catching it and cause damage by the straining the micro USB socket in the Note.
When you plug in an OTG adaptor or cable, the Note comes up with the message "USB connector connected" - a plain adaptor does not cause a message.
The picture below shows, from top to bottom, OTG USB adaptor connector, OTG USB adaptor lead, Wireless mini keyboard with mouse "touchpad", Bluetooth mini keyboard with mouse "touchpad".
Both mini keyboards came with wireless or bluetooth receivers which do not work with the Note as, I assume, they need "Windows" type drivers. The Wireless one cannot therefore be used with the Note (even though it also has a mini USB connection - probably only for charging use) whereas the Bluetooth one does work can as it connects using the inbuilt Android/Note bluetooth rather than using the supplied mini USB bluetooth receiver.
Hope this helps!

USB-OTG (they're all the same) works perfectly with some USB keyboards and mouses but not with all of them. I'm using Genius mouse and Microsoft Wired 200 keyboard.
Thanks, i'll try it. If it works it works
btw, neat bluetooth keyboard/mouse you got there!
I have a mini-wireless USB keyboard/trackpad from Kogan that looks closer to the mini-Bluetooth one in the 2nd post, and that works fine with my usb2Go adaptor and the Note. I know both look similar, but the button configuration under the trackpad on mine is the same as the Bluetooth one.
I like the idea of the bluetooth one mind you!

Dave

Thanks for that info, very useful. I'm considering getting one, can you advise where you got yours (a link would be great, if not, a manufacturer name and/or part number would do ... worst case can you advise approx price & dimensions?)
Although I have a USB one I bought from Kogan, this thread made me aware that there were now bluetooth ones too, so I've just ordered this one from Ebay:
http://www.ebay.co.uk/itm/Rii-Mini-i6-Bluetooth-IR-Keyboard-Touchpad-2-1-UK-Latest-Version-2011-/250901297139?pt=UK_Computing_ComputerComponents_KeyboardsMice&hash=item3a6ae1f7f3#ht_2215wt_905
It seems to be a slightly later design/model than the one shown in the 2nd post here, but you can find that too if you search ebay with the term "mini bluetooth keyboard rii".
Regards,
Dave
looks good - the universal learning IR remote is a nice add-on too. Let us know how it performs when you get it ...
meantime, I see you've got a wireless USB k/b already working via USB OTG. I'm awaiting my OTG adaptor so I can try that out with my existing (compact, but not mini) wireless k/b with optical trackball. Not sure how much current the Note can supply for OTG usage but I guess I can just use a powered hub if required?
Hi,
I had a new case and keyboard arrive for my nexus today but the keyboard doesn't seem to be detecting at all. I've been browsing all evening trying to find a fix but to no avail so far...
These are the specifics;
Nexus 7 wifi 32gb stock rom, JB 4.2.1
This exact MINI USB Keyboard (Can't identify manufacturer as the keyboard is built in to the case)
Mini usb - micro usb connector
I have verified the usb connector is working fine as I am able to plug in a mini usb charger to the nexus through it and it charges fine.
When I plug in the keyboard it doesn't work or seem to be detected in any way.
Where am I going wrong?
I can't try a USB OTG cable as I am not connecting a full size USB peripheral. I installed usb host diagnostics and ran it with the keyboard connected but I'm not sure how to interpret the results which are as follows;

You *do* need an OTG cable. It has two pins (4 and 5) connected. That's what tells the tablet that it's in host mode. If you want to adapt yours, here's the procedure (obviously, use at your own risk!):
http://forums.androidcentral.com/go...iy-making-your-own-otg-cable-image-heavy.html
tjupille is correct, a normal micro USB cable will only have 4 pins connected, the 5th pin needs to be grounded on the tablet side of the cable. If you can find/make a such a cable and if it's a standard USB HID keyboard then it should work out of the box on a stock N7 without the need for any special configuration.
I have also seen where some non-stock ROMs lose the OTG support. This wouldn't be your case as you are running what looks to be a stock ROM. Now then, I have had a few OTG cables go bad. Some of them are just made cheaply.
Thanks all, I understand the otg cable setup much better now. I figured that with a standard connection android should see the device as an input device and it would just work. Have a cable on order now. I have the kit to mod my existing adapter but for such a small amount of money I'd rather not gamble frying my nexus. Look forward to when it arrives as I keep going to use the hard keys!

dealextreme has some otg cables, you can purchase it.
A # of eBay stores carry these Micro USB Host Mode OTG Cable, originally designed for the Samsung Galaxry devices - I got one as a bundle along with the swivel case & screen protector, etc. Inexpensive & it works - on 4.1.2 and on 4.2.1 depending on the rom & kernel.
One of them selling a pair for under $5, free shipping and they are based in the LAX area of CA, mine arrived in less than a week - vendor has been around for years and sourced them mostly from oversea. The short piece of connecting cable is a bit longer than picture but still fit flat & tight against the bottom/side of the N7 with the case, so it won't be too bad flying 6 or 10+ hours with my own huge library collection of DVD's on a stick. Not a vendor / product endorsement & plenty of sources to get yours, plus Amazon ...

Mine was quite difficult to find as it's a micro one end and mini the other, but I've located one and it's ordered. Thanks for the links guys. I'm in the uk, it seems to be particularly difficult to find the one I need here for some reason!
Just my $0.02 on the whole OTG thing though.... why can't it be that simple to just connect a usb device and for it to work like things used to?? Why the need for an adapter? Surely these keyboard cases should all be OTG wired for maximum compatibility as a keyboard is never going to be a host device!
Ho hum...
Then if i understand good i need otg cable to be able to connect my keyboard ! The problem is my keyboard is already micro usb and i just find
OTG micro usb to usb 2.0 .
How to do then ?
Well I'm glad I found this thread after a couple of hours of fruitless searching (& mostly getting stuff about flash drives).
I tried to connect a case logic mini usb keyboard which I acquired for the princely sum of ten bucks, by using the cable that shipped with the Nexus and a usb gender changer, but the tablet did not recognize the device. I've had no trouble hooking the tablet up to a pc for chrome debugging, file xfers etc, and I tested the mini kb on a couple of pcs.
I thought it was something like this OTG adaptor thing, but couldn't figure out what was special about it vs. bog-standard usb plugs. I ordered one along with a powered usb hub, in case that was the/another issue, and look forward to getting this thing to work.
Thanks!
Edit: Sweet! The OTG adaptor worked like a charm, and with a powered hub I can run a wireless mini-mouse too.
Hi guys, I know this thread is quite old, but I have very, very important problem:
I've recently bought the same built-in to case keyboard with two wires: micro and mini.
The problem is that the micro one connected to the Nook Tablet or HTC Sensation does not work (although in case of HTC Sensation it is detected!).
When I connect the same keyboard to my sister's no-name tablet (something-made-in-China) via miniUSB it works like a charm! With no adapters, nothing!
The question is: should I try to find OTG adapter (and if yes, then which one? miniUSB to microUSB, or rather microUSB to microUSB?) ?
Thanks in advance for all your replies...

OTG for the nexus 7 is a bit different in terms of hardware requirements. Pins 4 and 5 on the micro USB side have to be shorted together for it to work. You will likely need an OTG cable that says in the description that it is compatible with the Nexus 7. Amazon and eBay are decent places to go.

Hey, I bought the same keyboard, foolishly.
Is buying another cable the only way to get to work?
Hi, I am relatively new to digital 'prototyping' so USB protocols and almost everything digital is new to me.
The long and short of my question is, if I plugged a standard USB flash drive into an OTG adapter, and then plugged all that into a micro USB to standard USB (which I doubt actually exists) and plugged that combo into a PC, would I be able to access the flash drive? How exactly do OTG devices VS 'regular' USB devices work?
From the circuit schematics I've studied, it appears that the only difference between a standard USB and OTG interface is a bridge across pins 4 and 5. So how would this affect plugging said OTG device into a PC?
Yes. Long as your device supports it.

So if I directly hardmodded a standard USB flash drive with a micro USB plug, bridging pins 4 and 5 to make the device OTG-ready, if I plugged that now hardmodded flash drive into a micro USB (female) to USB A (male) the PC would still read the drive as a standard flash drive?
This makes sense because apparently on the micro-usb interface, pin 4 is "sense"?

Thank you for your assistance.
Yes/no.
The standard (full-size) USB A and B connectors only have 4 contacts and 4 conductors.
The ID pin (#4) is only on USB mini and micro connectors.
You need to signal your cell phone to go into host mode.
That means that the connector plugged directly into the cell phone has to have a grounded pin #4.
Pin #4 is never carried over the cable.
In short, you need an OTG adapter plugged into your cell phone.
Modding other parts of the cable or the USB device you are using won't do anything.
You can (as I have done) take a razor to the connector that plugs into your cell phone,
take the connector apart and solder a wire from pin #4 to ground.
I've had a Galaxy Tab A 10.1 for over a year now and get the most use out of it by connecting a thumb drive via the usb connection (for viewing pdf files). It's worked great until a few days ago.
After connecting as usual there appeared a message at the bottom "something something disconnected" (the "something something" being I don't remember exactly what and the message disappeared before I could see) and now the usb/connection doesn't show up in the "My Files" window (just the "internal storage" and "sd" indicators, whereas before I got the additional thumb drive designation).
I've tried two different utg connectors, no good. I've checked the thumb drive in my pc, it's fine. I've tried connecting the tablet to my pc via the usb, it doesn't show up at all. I can still move files between my pc and the tablet via wifi but I want my usb connectivity back!! I suspect the connection the utg plugs into.
Also, (I'm not sure if this is a separate issue or related) battery recharge seems to take much longer ... is this a sign of the tablet getting old? I could understand if it was 3 years+ but 1 year??!!
Thanks for any help or ideas as how to fix this!
HGGuy
I'm assuming you are using an OTG cable to USB Drive or a micro USB drive right? In other words the part you plug into you Tab is a micro USB and not Type-C USB? If it is micro USB and not Type-C try this ... https://www.youtube.com/watch?v=sGGdsMsK3VU. If it doesn't work the pins inside are probably damage and you need to replace the OTG cable or the drive, what ever you are using. If Type-C USB same thing. Needs replacing. Those pins ware out over time and use. Thats my best guess with out pics and further information.
Edit: Found this Image of what damaged micro USB pins look like, the damaged ones being on the right...

Yes, I'm using a usb (to take the thumb drive) to micro usb connector. I suspect it's not a connector issue as I tried three separate connectors and none showed a connection to the tablet (i.e. the thumb drive did not show in the "My Files" page as it used to) ... all the pins on all 3 connectors look good, the fit into the tablet port is tight, no looseness. I've looked closer at the micro usb port on the tablet and I'm beginning to suspect that's the issue as a receiving contact on the outer edge seems to be damaged (possibly) ..
Thanks for the reply and the link to the Youtube video!

No Problem, I've never had a female Micro USB port go bad on me , but have heard of it happening. A good tug in the wrong direction I suppose could pull the solder connections apart or maybe even damage the innards. Is the Tablet taking a charge? I'm a little confused to actuality what part your referring too. Here is an image explaining what the different types of USB's I think you are using. Tell me what color circle you think is damaged. Or if you are using something else entirely different.
