Tested a thumb drive, it connected instantly and is behaving just like the SD card. Contents show up in the folder 'USB storage'.

Keyboard connected but device freezed. Had to restart the device. Will try some other keyboard. This one was a HP.

Mouse scroll wheel works too. Can scroll the page just like PC. Links or options are highlighted as the page is scrolled.

Here is a screenshot of the mouse pointer, i had keyboard connected too but i don't know how to show it on a screenshot.
I plugged in my Logitech wireless keyboard and mouse (thus connecting them simultaneously). Really happy!
I am now wondering if i can use the phone as a CPU and use my LED as a display. The input devices being connected wirelessly, it sounds do-able. Only question is how to connect the HDMI cable when the only slot is already serving input devices

I am just working on this setup, For that one need to use Bluetooth mouse and keyboard AND Samsung MHL HDMI cable.
I already had a Logitech Bluetooth mouse, and yesterday i bought Bluetooth mini keyboard which is HID and works very well with Note. Its available globally in <USD 20$.
My MHL HDMI is on the way, i should be playing around this weekend with this stuff.
Having teamviewer already configured for my work and home laptop, this should be real fun to use Note (CPU) and my HD TV

I have used MHL to TV, and bluetooth KB and Mouse for input. Works like a charm!

Any idea if those wireless devices that have their own dongles work?

That is exactly what I meant! Thanks! I have the Logitech Mini Controller (like the dinovo mini, sans Bluetooth) and it has a dongle. I love the keyboard/mouse combo and the flip up lid holds the note perfectly. I guess I am going to have to buy an OTG cable!

Can confirm the Logitech Unifying gear works (and allow simultaneous keyboard and mouse).

Hope Teamviewer doesn't disappoint - when I last tried it out it didn't support external KB/Mouse properly. Only one I've found that does is Splashtop (works really great with the MHL/BT setup like in the video in my YouTube channel).

I am looking forward to purchasing 64GB flash drive for connecting through OTG. Do you guys think it will be supported? What is the maximum size that it can support?

Note, right now, only supports FAT32 File-System.
So even if you have a 64Gig Flash drive, it will still have to be formatted in FAT32.
Windows itself does not format anything bigger than 32GB in FAT32.
Also, you can't put any files bigger than . . i am not sure, either 2 or 4 GB each on a FAT32 formatted drive.
Siyah Kernel has NTFS and CIFS support, but no Note Support yet.
Abbyss has Note support, but no NTFS and CIFS support yet i think.

My OTG cable works fine when connecting a USB stick or a card reader, I am able to use the memory on the attached card.
However, I connected the Logitech dongle for a wireless mouse but it doesn't have any effect on the Note. Am I missing some settings somewhere? I have looked but I can't find anything. I assumed some drivers would be needed for this type of connection but looking at your comments it appears you got it to work without issue.

I'm using a Transcend 16GB JetFlash USB3 thumb drive to play TV shows and general transfers to the device - I get over 20MB/s transfers from my PC to the drive over USB2, so it's quite a bit quicker than copying to internal or external SD on the Note itself.

Have you tried a different cable? Sounds like you've tried a different port, considering you plugged it into your 360...
Your USB port might be dying/dead....

I have not tried a different cable yet. I was thinking about gettin one from amazon to try. I hope it's just the cable.

If you have a PS3, some cameras, etc use the exact same plug. Anything mini-USB - even tho it doesn't look like it matches up, it'll work.

Yes, I know. I was trying to coax you into using other cables that are around your house that have this similar plug. The 'default' HTC cable looks like the one you posted, but I wanted you to be aware that other cables will work just fine - like the miniUSB standard cable I posted above!!

Oh ok. Well I guess I could try a few. See what happens.

I have the same problem with my TP2.
Tried different cables, different computers, but problem is still there.
I can't connect TP2 with computer, can't sync with Outlook, at least I can flash ROM from mSD card
Any ideas, solutions, maybe there's some fix for this issue?!

Has it ever worked? Perhaps it's a hardware issue with the plug. I assume it charges OK?

^ Yes, it worked well in the past. Charging is OK, wiht AC adapter and with USB cable connected to computer. Only ActiveSync doesn't work.

Have you guys tried Deleting any/all Partnerships and then uninstalling and reinstalling Windows Mobile Device Center on your PC and then trying again?

Yes
I even reinstaled the system, Win7, WinXP, changed cables, changed computers, even changed ROMs (Energy, Jackos...), still nothing
Weird thing is that charging works just fine, but sync don't...?

I suspect you have a hardware problem with the port on your device. Maybe use a magnifying glass and look at the brass pins inside the port and see if you see any bent or missing pins. You could have two pins touching that could be shorting. Maybe the only solution is repair/replacement.

I'd say that is your best bet. It's entirely possible that the pins for charging (only 2) are fine, while the remainder (I think there's a total of 11?) or a portion of the remainder of the pins are messed up...
Good luck!

Try to turn the high speed network thingy off, in your USB connection on your phone. I forgot what it is exactly called but something of that sort.

Yeah, try going into Settings and uncheck the box that says Enable Faster Connections. It's in Activesync or USB to PC settings.

Sorry, guys, but I tried that first: Start > Settings > Connections > USB to PC, uncheked the box "Enable faster data syncronization", still nothing

When you connect your phone to the computer, does it even recognize it, I mean does your computer detect that something got connected to the usb? Were you always plugging it in to the same USB port on your computer?

I HAD the same problem-charging was ok, but no sync. Well...
First of all, check your cables (my TP2 won't work with cables from my old TYTN II). Use cables for particular model, those contacts can be tricky. Now, in your phone's USB to PC settings uncheck "enable faster data sync". It worked for me. Now phone syncs, no problem. When pc starts recognizing your new device, phone will use 3g connection to download some 11MB of drivers, so you must have some credits in order to connect to 3g. Now it works like a charm, no problems whatsoever...
If your PC recognizes the device, but doesn't sync, try this: when connected go to your PHONE's active sync and sync it from there. Worked with me once I had that "issue"...

usb mass storage? how?

well, this is rather embarrassing, I can't seem to find a way to use the phone as mass storage like I did with T989.
I just got it today brand new, already rooted via odin > cwm method.
When I plug in usb cord, I can only access it via MTP but it won't let me transfer large 700mb file.

Enter Settings and tap "Storage". There you should have a menu icon (the vertical triple blocks - on my tablet it's in the top/right - YMMV) which gives you a option called "USB computer connection". Tap it, change from "Media Device (MTP)" to "Mass Storage".

In this case your SGN2 doesn't seem to support Mass Storage mode. It's there on my SGT10.1 running CM10.

For anyone with a similar problem, the white USB cable that comes with this phone (in some systems like mine) doesn't send data to computers - it only supplies power.
Many people have reported this and I just confirmed it on my system. I connected my NOte 2 to my system with 5 other usb cords and my system found the device. Every time I connected it with the Samsung white usb cable, the computer doesn't see the Note 2.
Either Samsung did something with this usb cable or they really are sending a lot of defective usb cables out.

Thats not true i always use the white usb on my computer..... Its just hit or miss sometimes

I'm not able to mount it as a mass storage device either, my only options are "Media Device" or "Camera", neither of which show up as an actual drive on my windows machine. and i'm not using the white usb cord that came with it, i'm using my own cord that i've used for years, and with many other devices.

Coming to think about it (totally forgot about it)...
Maybe give Easy UMS a try. I use it on my SGS3 for USB Mass-Storage Mode, and according to the thread it also seems to work on the Note 2.
Though, keep in mind:
This app will make the external (not the internal!) microSD card of your Samsung Galaxy S3 (International, US versions, International LTE) available as USB mass storage device.

Easy UMS WORKS!

I'm running Jedi-X V1 (wanted MultiView real bad, which works sweetly) on my T-Mobile GNote2 and Easy UMS worked GREAT.
It's usage is not extremely intuitive: Click the UMS button to make it run in mass storage mode, attach to computer, do your file transfer thing, SAFELY EJECT when done, wait a few seconds, then click "Mount SD" to get the card back for your android to use.
After using the phone I went to re-connect it to the computer, and found that a couple of apps were using the SD card, so I long-pressed home, clicked Task Manager (the pie graph at the bottom) and used the Clear Memory function to kill innactive apps, freeing the card up to be unmounted and UMSed,

Review Ravpower WifiDisk: Mobile wireless storage reader

Ok so I've been somewhat following Ravpower for a while since I really enjoy their 10,400 mah powerbank and saw on amazon that they have this new product called the WifiDisk out. In comparison, I've been looking at the Seagate Goflex Satellite Mobile Wireless Storage too but it's a bit on the pricey end, and then somehow I came across the Ravpower WiFi Disk on Amazon and went ahead and bought it. It's actually not a wireless mobile external hard drive, but a wireless memory card/storage reader and battery charger. This can read SD cards, USB flash drives/ any storage device that takes 2.0 usb ports. Also you can even charge your phone or tablet too since it has a built in 2.0 USB port.
Pros:
- Creates its own network wireless point/hotspot so I can access my files from anywhere through my phone and tablet.
- Can enable DDNS to allow you to remotely access the device by a registered hostname. If set up (which comes with a cost if you choose to do this), you can access this drive on your tablet, phone, computer from anywhere where there's internet while leaving this device at home. However I think having this personally with you is a better option.
- Built in user interface which can be accessed through any mobile web browser and standard computer or laptop.
- This can be an instant bridge between my computer and portable devices. Once I load something onto the wifi disk with SD card from my computer for example, I can instantly see this on my portable device after refreshing.
- Wirelessly stream my videos and music and access files to my nexus 7.
- I can wirelessly connect this to 5 different devices where I can then stream 5 different videos at the same time. Friends have been very grateful during our road trip.
- I can still connect to my regular internet through this after setting it up.
- Can also be used as an external battery charger. Contains 3,000 mah battery.
- I have an external hard drive already and I can plug it into this, which gives my hard drive wireless access.
- Can have almost unlimited amount of storage space since there is no fixed amount, however you would have to carry a lot of SD cards and/or thumb drives if you want to carry your entire library to minimize bulk and weight.
- Having this device has expanded my storage from 8g on my nexus 7 to unlimited.
- Small, thin, and light to carry around. Really good size to be tucked away in a backpack, purse, duffel bag. Even a pocket.
- Cheaper alternative to more expensive wireless hard drives or cloud services.
Cons:
- Suggested app, "MobileFun", have some issues. I can't seem to transfer files from my wifi disk to my phone and errors sometimes pops up in some Asian language.... Luckily I can access the user control panel on the browser by putting in the wifi disk's ip address http://10.10.10.254/ into the url field.
- Takes a while for the network to show up on my phone and tablet. Might be standard though.
- Wish battery life was longer.
- Range radius is about 10-15 feet.
- Scratches easily and since it's white, I can see it getting dirty fast if you're not careful.
- Wish battery life was longer. 3000mah is not enough for long travels.
- No power gauge so I can't tell how much battery is left in this thing.
I wish the battery life could be longer but I guess 5 hours is ok too if you have a power source kind of close by - like if you're using it on a road trip. I can see some people may want more since this is a pretty useful device and can be used for a long time. The range of the WifiDisk could be better too but still impressive considering this is wireless. Friends and I had a caravan of 3 cars during our trip and the range was ok at times, but it did drop if a car drops 1-2 car lengths away from me The connection does get spotty. Great for media but not so much if you want to get work done because you can't directly work on your files on this device. You can only download it then work on it directly from your laptop or whatever, and then upload it again back onto the sd card or storage with this wifi disk.
Overall, great product for the price. I'm pretty happy with it.

I just saw these on Amazon, one thing I wanted to be sure of. Am I reading right that this will act as a wifi file server, even when no internet is present? We are about to do a long car trip, and it would be good if I could load up one of these for the girls to watch movies on their Kindel Fires on the road.
Thanks

Yup. And it works great. If you go through the Wizard setup, you can make it so you connect to your home internet too. But it works without internet as well. It's its own network hotspot so all you have to do is connect to it from your device as if you're connecting to a new wifi network.

Can the USB port act as a Pass - Thru (when directly connected to the tablet, obviously) for High powered devices such as USB Ethernet Adapter
ie:
USB Ethernet --> RAVPOWER --> USB Cable --> Tablet

I'm not exactly sure.

Got mine and works well. When inserting any usb, it powers the USB which diminishes battery life when stored, so only plug the USB in when you need it otherwise its a pretty cool product.
I have an Anker 10k battery that I add to the mix and my WD 1tb. Yes it's clunky, but when sitting in my laptop bag, I can't see it, but works for hours and hours.

wifi vs. mobile data
A possible showstopper for me is that if I connect to it via wifi, then I lose my mobile data connection. I'd like to be able to use a mobile data app like google navigation while at the same time playing files from the rav wifidisk. If I can't keep both interfaces on, I may end up returning it to amazon. Too bad; it seems to be an amazing device.

I found a solution although I'm not sure how reliable it'll be.
The ravpower wifidisk has two wireless connections; one that accepts clients (LAN) and one where it acts as a client to another wireless network (WAN)
Fortunately it's cifs server listens on both.
I turned on wireless tethering on my phone. Then I connected from a laptop to it's LAN interface (WiFiSD-xxxx) and configured it's WAN/internet wireless connection to connect to the phone's tethering AP. I also ran the windows mobilefun to discover it's WiFiSD-xxxx ip address and connected via internet explorer. username admin; no password.
In there I discovered the IP address that the tethering AP had give it. If that dhcp assigned address doesn't stay put, I'll put in a static address.
Back on the phone, I ran cifsmanager to connect to the RAV, using the ip address the RAV requested from the tethering AP. Now I have both mobile and ravpower connections on the phone.

Do you know what settings you used for CIFSmanager ? I cant seem to get it to work on mine.
Here is a quick connectivity review I did :
http://forum.xda-developers.com/showthread.php?p=41751832#post41751832

Hi Green Ranger,
Possible to transfer digital photographs directly from SD card to portable HDD, when both are mounted onto this device.
With only Android smartphone instead of computer / laptop?

Apologies for the late reply, but yes, if you use es explorer or solid explorer, you should be able to browse to your device and copy/paste images into there. I think you need a smartphone/PC to do the transfer, the wifidisk wont do it itself.

Confirmed Working + Tutorial: USB OTG on Galaxy W

Galaxy W Users is having a major improvement! (as i feel), because Arco68 on his "[ROM][JB][JZO54K] CyanogenMod 10 ALPHA (Build 7)" Mod Thread finally enable USB OTG Support on our beloved phone, the Samsung Galaxy W
Thread: http://forum.xda-developers.com/showthread.php?t=1990795
Basically, what does USB OTG do is to make our phone able to connect to external USB devices such as Flashdisk, Card Reader, Keyboard, Mouse, ETC. Myself has tried it with mouse, keyboard and card reader all in single usb HUB and it's works perfectly!
(to make USB Storage such as card reader or flashdisk to be recognized while connecting other devices such as mouse and keyboard, the card reader should be plugged after everything else. This way you can use keyboard and mouse, while working with your flashdisk/hdd/card reader all together)
Using external power source, as our phone doesn't supply power to the Micro USB Port

Mouse confirmed working
Usb Hub Setup
Card Reader Confirmed Working
Usb OTG Converter that i use
Simple usb hub mod for power injection
Very simple schematic
If you have spare time, the setup can even made portable by replacing the usb power adapter with
5V DC Regulator + some battery (9V battery will work i think, the regulator will convert 9V to 5V as required)

Galaxy W Users is having a major improvement! (as i feel), because Arco68 on his "[ROM][JB][JZO54K] CyanogenMod 10 ALPHA (Build 7)" Mod Thread finally enable USB OTG Support on our beloved phone, the Samsung Galaxy W
Thread: http://forum.xda-developers.com/showthread.php?t=1990795
Basically, what does USB OTG do is to make our phone able to connect to external USB devices such as Flashdisk, Card Reader, Keyboard, Mouse, ETC. Myself has tried it with mouse, keyboard and card reader all in single usb HUB and it's works perfectly!
(to make USB Storage such as card reader or flashdisk to be recognized while connecting other devices such as mouse and keyboard, the card reader should be plugged after everything else. This way you can use keyboard and mouse, while working with your flashdisk/hdd/card reader all together)
Using external power source, as our phone doesn't supply power to the Micro USB Port

GOOD BRO (Y) :good: :good:

I believe a powered usb hub bought from any electronic store should work. They are quite easily available in Amazon or eBay.

Hmmm, if a usb card reader works, i think usb stick should work because they both works quite the same way? and if a mouse works, also i think keyboard should works too. maybe you can plug usb Hub, then plug both mouse and keyboard at the same time and si if it works

I can plug keyboard and mouse to my wonder with cm10 alpha7.
If you said how can I plug flash sticks, card readers and externals, read this:
I hooked an external powered usb hub and plugged usb stick. it works
2tb external drive works with paragon ntfs mounter after some config...
what I did:
-mounted the ext.drive
-opened es file explorer, created "directory_name" directory
-launched the paragon app
-dismounted and tapped "mount..." button
- tapped "choose mount point manually..." button
-selected /storage/directory_name
-tapped select button
-minimized the app with home button

Confirmed working but still on a hunt for a portable DC power source

You must make usb otg by yourself, just follow the tutorial above. :fingers-crossed:
If u buy from any types of usb otg nowm I think it doesn't support for galaxy wonder. But except if there is someone/factory has make it and sell it

Hi Batur, you can do otg yourself.
Aftermarket otg's will not work because there is no power on it.(our phone needs ext power for usb devices)
You must buy an usb hub and change it's usb cord to micro usb and hub must have to got an external power jack.
If you have questions about it, you can send private message to me.
You can write your p.m. in Turkish or English.
Sorry about my bad English.

Good job bro!

got a usb otg cable today to experiment
i own a nice 7-port external power hub D-Link DUB-H7
tried to connect it to my phone, it even doesn't recognize it as a host)
another try was using an external hard drive with two usb cables - one to phone, other to power 'dumb' usb port
result - phone talks 'bout clear or damaged usb storage, possibly 'cause my drive has two partitions..
waiting for cheap chinese usb hub to mod it for power supply and continue research)

Anyone tested on joystick? would be great while playing Dead Trigger :laugh:

got a cheap usb hub today, thinking to mod it for external power supply
your scheme is to connect +5v directly to 5v contact from phone (it's not giving power) and gnd to phone's gnd respectfully
won't it damage the phone? maybe use some kind of diodes?
and is phone being charged while such modded hub is connected?

I've modded a usb hub to add external power supply....that's what I've done: I' ve put a second cable to power the hub and cut the VCC wire inside the other cable of the hub to avoid current return... to power it I use a 5V CC 1A power supply....I've tried this on my notebook and it works perfectly..but when I connect it on my galaxy w there is no device connected....but as you can see on the picture led light of my usb flash drive turns on, so it should work, but it isn't.....what is wrong??? any suggestions??? help please....I repeat: on my pc all works perfectly!!!!

So i have this usb hub, do I just take another usb cable and solder them in onto the board?
