Review of the GrayBean Card reader-OTG USB Hub #GB-CR

This is my review of the GrayBean multicard reader-OTG USB Hub Connection kit Model: GB-CR
The Graybean GB-CR is a multicard reader and USB hub which is shipped and sold by Seller1ON1 via Amazon.com. it lists for $13.26 and comes with a Blue mini capacitive pen which for us Note 10.1 users, is not needed. The description on Amazon states that it can be used on the following devices..
Samsung Galaxy tab P7300 / P7310 /P7500 / 7510
Samsung Galaxy Tab 2 7 inch / 10 inch
and I can attest that it also works for the Samsung Galaxy Note 10.1
Packaging and Design
The device came in a plastic zip locked type of bag along with the mini blue capacitive pen.
Front and back of the package.
When I took the device out of the packaging I was actually surprised to see how small it is. The image on Amazon makes it look much larger. The dimensions of the unit are shown below.
Available ports
The available ports on the device are as follows...
1 SD card
1 TF card
1 MS card
1 M2 card
3 USB 2.0
1 DC Input 5V (3.5 1.35mm, 5V, 2A)
There is also a led light that turns on once you attach the device to the tablet.
Although in Amazon there is an image of the device with a power cord attached to it, (as shown below) the device does not come with any power adapter. (More on this later).
Uses and Testing
First let me state that I do not own any MM, M2, or TF cards, so I did not test those ports.
I inserted the Graybean into the Galaxy Note 10.1 and unlike cables and plugs from Samsung which have the Samsung name on top of the plug, the one from Graybean does not indicate which is the top of the plug. So you have to be careful to make sure that the plug notches are facing upward when pluging in the cable into the Note 10.1 otherwise you may damage the port on the tablet.
I proceeded to test the SD card. I inserted a microsd card into the usual SD card adapter and inserted it into the GrayBean.
Immediately the File Manager opens up and i see UsbDriveA. i select a video off of the sd card and it plays flawlessly and without studder.
I then wanted to try to see if I can use a mouse so i attahed the dongle from my Logitech Wireless Touchpad and it also immediately placed a cursor on the screen.
Considering that it has numerous USB ports, my next test was to see if another SD card can be attached.
As you can see from the image, both UsbDriveA and UsbDriveB show up in the file manager.
At this point I wanted to see if I can use a usb extended cable with the GrayBean.
I inserted the AmazonBasics usb extended cable and I was able to still access the sd card.
I was able to test three sdCards inserted in the GrayBean and all three showed up in the file manager.
A Note on External Power and Devices
As mentioned above, the GrayBean does not come with a power adapter. In the Amazon description it states 3.5mm outside / 1.35mm inside, 5V, 2A power port and locating a power adapter for the GrayBean is not easy. One buyer on Amazon mentioned the Enercell adaptaplug tip 'H" would fit the port, but trying to find the tip as well as the actual cable/adapter has been a bit hard.
I did manage to have bought a while back for my Dell laptop the BiXpower USB Port Power Cable that comes with 3 extra connector tips and which so happens to fit the GrayBean.
I did managed to attach an external usb hard drive and the file manager was able to read it, but the hard drive has to have its own power source and also be formatted to fat32, otherwise it won't be seen by the Note 10.1. since the device itself even plugging in a power source, will not power up anthing attach to it.
Conclusion
Its a very useful device that allows numerous sdcard and usb flash drives to be connected to it. Although I do not see myself carrying it around all the time, it will come useful on my desk. I only wish the manufacturer would have included a power adapter withit as well as make the power aactually power up the device (such as hard drives etc) that are attached to it.

Great review, but I'm unclear on something. With the power source connected to the hub, were you able to charge the Note 10.1? I bought the hub and it's tremendously useful. If I could charge the Note while this was plugged in I would definitely go buy a plug.

You're welcome.

My first one fit VERY tight when connecting it to my Note. The seller RMA'd me another and although it still is a bit tight it does not seem like it would damage the port.

Sorry for my lack of knowledge. Does this adapter take all 3 sizes of SDHC Cards without the use of SD adapters? Thank you.
EDIT: Answered my own question by reading the reviews on Amazon. It takes SD and MicroSD. No MiniSD. I just ordered one myself at $18 and price just popped back down to $14. Can't win sometimes.

Great review!
I've already ordered one of these as well (as a standard OTG tablet to female USB connector and a few more charging cables) through eBay. I'll give my thoughts when I receive it, but what appealed to me over the official Samsung OTG card reader, is that this one connects via a short cable, rather than attaching the device to the bottom of the tablet itself.

Could u connect an external dvd drive to it and see if it works and plays the dvd or something

+1 please test... mainly b/c i've been lookig at buying this here it would be amazing if it worked out of the box on the note 10.1

I bought my first Graybean Hub/CardReader from the same amazon vendor as noted in the first post here and it was not recognized by my Note 10.1 at all; no LED lights. I returned it and got another one. As least the second one is sporadically trying to connect (as if the connection is not secure). No LED lights and never got any notification in my file manager. The 30 pin connectors are really tight. Looks like I'm taking that one back too and exchange it for a 3rd one. Noting it each time in my Amazon product review.
Also, both of these received from Amazon/Gray Bean did not look new. There are many scratches on the plastic area of the 30 pin connector as well as the main section. Product package is not sealed by design- just ziplock. I would like to know if any of you are having or had the same issues right away or after using it a while. Or can you offer any advice? Thanks so much.

I got mine last week, but haven't been able to get it (or the straight OTG USB adapter I also bought) to work. In both cases, the OTG connector is properly recognized by my Note (the system reports a USB connection when I plug it in). But if I plug anything into the OTG connector (thumb drive, keyboard, mouse, SD card) it mounts and then immediately dismounts and then continually loops mounting and dismounting the plugged in device.
Haven't been able to figure out the problem (may be the ROM I'm running, or the fact I'm running a 800X ROM on a 801X device)?

Your post put me into action. I hadn't tested mine so got it out and it works fine, though it won't show more than one attachment at a time. That's a bit odd. Not going to mess with it right now, though.

What's strange is, when visiting the Graybean website, I cannot find this card reader.. I also noticed that there are no serial numbers attached to the actual product.

Took a jack hammer to get into my bag. Top was sealed above zip lock and couldn't rip it. Lights light and items show up in file manager. Only tried Samsung's so maybe that's why more than one at a time didn't show. My plate's pretty full today and don't have time to mess with much.

The N10 would have to be dipped in platinum and covered in rare gems for me to ever do that. Even then then I'd keep my GNote.

I tried to get hold of such a device on amazon.de, they don't have the item available. Amazon.com has it, but will not ship abroad :crying:
Investigating a little more on various sources, I came back to amazon.de, where I found a lookalike device (USB 2.0 Hub OTG Connection Kit + MS TF SDHC M2 Card Reader Kartenleser Adapter Kabel für samsung Galaxy Tab 10.1) for a reasonable price.
This unit comes with a powercord (which connects to any USB power supply), less pen (which I don't need anyway on the Galaxy Note 10.1) also the Galaxy plug is marked with a line on the upper side, so you don't have to try and break it.
Functionality is as described, alas the Galaxy Note does not recharge on the power from the hub :crying: which is what I had hoped for. Not sure if the thing can be modified to supply power to the Galaxy too. Any suggestions are welcome.
I don't upload photos, as the unit is exactly as on the pics above.
Thanks for the review, which made me aware of that option in the first place. :good:

Wireless charging confirmed working on our T-mobile S4

Hey guys, don't know if people have done this already, but I just got a T-mobile S4 for testing this weekend and I wanted to find out if the wireless charging port was enabled since I've done the touchstone wireless charging mod on my S3 and note 2.
It was especially a PIA on the note 2 since T-mobile, in all of its corporate and engineering wisdom, decided to disable the feature for the Note 2, even though it was enabled for the S3. So for those of you who don't like to dissemble your new phone and solder on a tiny PCB, you'll be happy to know that I confirmed that wireless charging ports on the S4 is indeed enabled.
I took a pack of 4x AAA battery assembly, which provides ~4.7v of DC power, and connected to the charging port in the back. The small pair on the left is the charging port, the pair on the right is supposedly NFC, even though the NFC antenna is located on the battery for S4.
As you can see from the pics, the "the phone is now charging wirelessly" notification pops up when the circuit is live, which is pretty annoying IMO and can't be disabled (that's why we have custom roms right?)
I haven't gotten a chance to install the actual touchstone wireless charging receivers on the back yet, as this is a test unit that I have to return, but I don't imagine this to be too different than on the S3. There will be a slight bulge, but it'll be worth it.

Just follow the instructions from this thread (it's for an S3). The design for S3 is pretty similar, so it should work. Remember the positive pin is on the left, negative (ground) is on the right.
Also note that the touchstone mechanism is not Qi compatible, so it wont work with the newer charging mats for Nokia or HTC.
And always remember to perform these mods at your own risk.

Did you install any receiver on the S4?
I didn't mean to confuse anyone, I only confirmed that it is POSSIBLE to perform the mod. I used a 4.7v DC power supply to test if the wireless charging pins on the back are live, which wasn't the case for T-mobile note 2 so I had to check to make sure.
If you already have a Qi charger, you can get one of these receivers and connect it to your phone, then you'll be able to charger with your mat
http://www.ebay.com/itm/qi-Wireless...l_Phone_PDA_Chargers&var=&hash=item51abef6de9
But I would argue that the touchstone method is superior to qi if you plan on using it in a car, as the magnets keep the phone in place is it's really convenient to connect/disconnect when you're driving.

Samsung will be officially supporting wireless charging for the S4 through accessories. The ad for the pad and back wireless charging cover is already listed on the promo S4 accessories page. http://www.samsung.com/global/microsite/galaxys4/
Though there seems to be no price or date yet.
Of course there will be 3rd party wireless charging solutions as well.

ive got a palm touchstone but what receiver do i need to buy to have my GS4 work with it ?
also;
can anyone confirm or deny wether or not the palm touchstone + receiver will trickle charge the GS4 after it is fully charged ? (or does it completely cease charging until the phone is physically picked up and replaced ?)

the link above is the thread with a tutorial on how to do the mod for S3, should apply to S4 as well.
I can confirm that it trickle charge S3 and Note 2 ( if I understood you correctly, it will keep the phone charged as long as it's on the touchstone base), shouldnt be any different for S4.

Took the Qi wireless receiver pad from my Galaxy S3, had to slightly tear it apart to reverse the little gold inserts that create the contact points for the wireless battery charging and now have a fully functioning wireless charging Galaxy S4 !
Saved myself quite a bit of money doing that.

It seriously only took 5~10 minutes once I'd figured out which way to put what.
I have the photos set up and just need to put notes on them explaining what I did.
Will post them when I get home tonight (12am CT)

Ummmm, from everything I read the pins you have it hooked up to are NOT the ones for inductive charging, the gold ones on the right are......
I could be mistaken however. I remember the s3 used those pins, but I've read in a couple places that the ones made specifically for inductive charging are the ones on the right above the battery.

the smaller set is wireless charging, the larger set is presumably for additional NFC antenna (although I measured no resistance in the circuit with my voltmeter), as the back cover seemed to have a carved out area for a NFC like the Note 2 did.
Although the S4 battery says "NFC" on it, which seems like samsung made a last minute decision to put NFC on the battery instead of the back cover... oh samsung ¯\_(ツ)_/¯

Nope, the NFC is in fact in the battery, the same way Samsung has been doing it for years now. They made no change.

[Q] S4 mini wireless charging

Dear all,
I'm considering buying a mini S4, but enough for me to essentially probably Wireless charging. Search through Google gives a lot of references to receivers and cover Qi standard for S4 and S4 active, but I can not find similar for S4 mini.
Are there any options?

S4 Mini doesn't have the wireless charging chip/card in the back by default...
For S4 and others, you could add in the capability by adding a Qi card like this: http://www.kogan.com/au/buy/qi-wireless-charging-card-galaxy-s4/
If you look it has a contact strip coming off it (Second photo) that connects to the phone via 2 pins in the back of the phone, as far as I am being told by "Kogan" (A local Gadget Co in my Country) S4 Mini does not support the Qi card as when I pull the back off my phone, I dont see those 2 pins like the normal S4? So no way to charge the battery? I wonder if it could be modded to contact directly to the battery??? but I guess the phone would have to control where the current goes so that wouldn't work.
I wonder if that would work though, mod teh Qi card so it connects to the battery pins so that when you place your S4 mini with Qi on the mat, power is drawn from the Qi side and not the battery thus, saving you battery power rather than charging it? Thinking about it, this might a pretty cool device to put into full scale production???

What about "universal" chargers like this: http://bit.ly/1aLGut6
Anybody tried it with S4 mini?

There's already a discussion about this topic here in the Accessories section:
http://forum.xda-developers.com/showthread.php?t=2415990
Maybe you can find some answers there.

[Q] Any solutions for QI wireless charging Zerolemon battery?

The zerolemon battery covers the standard pinouts to the QI wireless receiver for wireless charging. Does anyone have a solution, workaround, modification or source for a QI receiver that would work? It is so convenient just to put a phone on a stand and top it off, even with the massive 10,000 mah battery. I am NOT interested in anything that involves soldering anything to my precious phone, or modifying the phone in any way, just the receiver. Thank you in advance for any thoughts!

Maybe one of these cheap charging pads can be modified instead of your phone? They dont seem to have one specifically for the note 4 yet on here, but for $6 thats a pricetag you dont have to cringse about when you srtart soldering on it..
http://www.fasttech.com/search?qi inductive charging receiver patch for note 4
Hope it helps.

Basically you have to extend the contacts from the phone back. You don't need to solder. You can do it with double stick foam tape, masking tape, adhesive copper braid or sheeting and the adapter. My adapter has not arrived yet so I am not sure it will fit between the Zerolemon battery and the case back. I did something similar to get NFC working with my Zerolemon on my Note 2. Once my adapter gets here I will report if I am successful and the fix is safe and dependable.

Don't Modify Anything
Instead of modifying things just use this simple device available on Amazon. Make sure the output matches the requirements of your device before you purchase or it will not work. This is the one I purchased for use with my LG G3 and the ZeroLemon case with the extended battery and it works just fine. You still do not get the NFC capability, but the wireless charging works. But then who actually uses the NFC anyway?
Just search on amazon for micro USB Qi antenna or wireless charging antenna. (the forum won't let me post the link)
This adapter is very easy to install and adds the Wireless Charging / Qi charging back to your phone. Amazon has several versions, just make sure you get the one that has the correct configuration on the plug, either small side up or small side down, and you also need to make sure you get the one with the correct output. For the Lg G3 it is the one with small side down, 5v-1000ma output to make it work properly.

The Zerolemon battery covers the ports, making the standard Qi receivers not able to attach to them, that's why we need a different solution.

Actually, that is not true. I have installed the exact item I was talking about, and it works perfectly fine. The cover over the port does not fit "air tight" over the port and has plenty of room for the adapter to fit between the cover and the phone. This is why I had suggested the item in the post.

The Note 4 Qi contacts are in 2 places. The upper one, just to the side of the camera, is not covered by the Zerolemon Battery, and does not pose a problem for connecting, but the one next to the battery IS completely covered by the battery itself. Maybe I'm missing something? I don't care about NFC, but would really like the Qi charging feature. If you know of an item that would work, please PM me a link. Thanks!

Not for a Note 4, different contacts (won't work).

I really thought I was in the G3 forum...sorry about that.

They make a qi receiver now that plugs in the charger port of the phone and then flips back to the battery door it's on amazon like 15 bucks. Place case over it to protect receiver and phone any your good to go. I'm sure this will work just fine for ya there a universal qi receiver for tablets and phones with no battery door.

Here is a pic for you.

[Q] Galaxy Ace 2 wireless charging

Hi,
my fried have Samsung Galaxy Ace 2 GT-I81160P and we found some kind of antena in cover with two copper contacts, that fits with two contacts on phone back side.
Is it only some kind of antena extension, or is it antena for wireless charging?

- Nice one.. NO - this is of course not wireless charging - This is the NFC (Near Field Communication) Antenna
NFC is the P in GT-I8160P - The Phone without is called GT-I8160 (without P)
