[Q] Can't use OTG on Tab 7.7 - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

Hi all, I have had a Tab 7.7 for 12 months and have been using an OTG adaptor to copy jpegs from my camera's SD card to the external SD card in my Tab. All of a sudden the whole process has stopped working. My Tab 7.7 has ICS 4.0.4. and is NOT rooted. Previously when I plug in the OTG adaptor the File Manager appears showing the folders on the SD card in the adaptor. When I plug it in now I get the message "USB mas storage removed safely" and that's it. I was thinking I might re-flash the rom but since I can't even get Odin to load on my windows 8 PC (it flashes on the pc monitor then goes off) I really can't be bothered. I went to the trouble of running Odin on a windows 7 PC at least it loaded on 7 but wouldn't acknowledge the Tab being connected. I thought I might have a driver problem, but has anyone on this site tried downloading a driver for samsung tab 7.7, it's a bloody nightmare. You get all sorts of crap from checking what drivers are missing or outdated on your PC then having to by a copy for $29.95. I'm really over it. When I rooted my Mororola xoom 12 months ago and flashed ICS I had no problems at all, there wasn't a link like we have now that sends you to a site that takes 5 hours to download a tar file or you could buy a subscription and do it in 9 mins. Can anyone please offer any assistance with my problem before I toss it in the bin. Many thanks

Yeah maybe try a few different things connected to see what exactley is the problem.do you have any other usb things you could connect?

Thanks, I tried a laser mouse and the led under the mouse dosent light so I suspect the 5volt rail has gone somewhere. I'll pull the back off and check connector. I will post outcome.

Have you tried a different sd card?

Yes sure have, 3 to be exact. I've changed my mind about looking for 5 volts on the usb connector. I'm just not going to bother trying to connect a SD card through the USB port. Life is too short to stuff around

[Q] usb device not recognized?

Hopefully a simple fix.. When i plug my unlocked captivate in my computer reads usb device not reognized? So then i went thru to try and format this brand new card and it wont let me select format? Im not sure what to do and am stumped. an help would be appreciated
try a different cable. for some reason mine gets recognized about once out of 50 tries with the cable that came with the phone but when i use a different one it works every time.
tried 2.. no change.. more info.. when i plug the usb in.. it says select usb mode..kies, media player, mass storage or pc internet.none seem to make a difference. but it does seem to let me format the card and does make it appear available in the sd card and phone storage?? its very confusing..
I ran into a similar problem 2 days ago. My phone was fine for 30 days and then all of a sudden the usb port crapped out on the phone. I had tried multiple pc's, my mac which doesnt require drivers and then a trip to the AT&T store. Those idiots were a waste of my time but tried to connect it to a box for sucking down phone numbers and it wouldn't connect to to the phone either. I am not sure if its a problem from a rom I installed but sorry to say they are sending me a replacement phone tomorrow.
I wouldnt have belived it but a co-worker said try a different usb plug on my computer.. Im glad it fixed it.. a little humbled but im posting just because it may happen to someone else. Whats weird is the usb port works with every other device?? strange but true story thanks for the responses...
yeah none of my usb ports in front of the comp worked, tried back usb ports and had no issue, also keep in my i had drivers installed before hand.
win 7 x64
all of a sudden i cant get my PC to see my captivate, at all. So now I cant do Odin! tried all the ports and also another computer. Ideas anyone?

Captivate Cant Connect with USB

I've looked everywhere and cant seem to find an answer, so i figured i'd start a new thread.
My captivate used to connect to my computer just fine, but there was another computer it would just NOT connect too! Well, after a few months, it stopped connecting to my home computer as well.
I have USB debugging on, the phone is rooted and everything. When I plug it in and mount the USB drives, i get drives J and K on my computer, one for the internal storage, and one for the SD card i have in the phone.
When double clicking any of those drives, it just sits there and reads forever without ever doing anything. I can use the SDK to run "adb devices" and it see's the phone, Odin One Click finds the phone but freezes on reading file line, or just fails all together.
Any ideas?
Try reinstalling the samsung usb drivers and restart your computer, that'd be my first step.

You have to be on the touch wiz home screen if you're trying to connect to Kies, otherwise turn on USB debugging and you should be good to go

SeenNotScene: I've uninstalled, rebooted, re-installed several times. I've been having this problem for a couple months now and i've tried everything i can think of. It doesnt work
bkhams: I dont even know what Kies is? I always have USB debugging turned on, and once connected i bring down the drop down menu and mount the USB so i can access my phones files as if they were another drive.
I had the same problem, and Samsung peeps told me I had to use the USB cable that came with the phone, low and behold they were right. Connected right away with the USB that came with the phone, could that be your problem?
I had the same problem in the past and it was actually a hardware problem with the Captivate and not anything with the computer. I ended up taking the phone in and they exchanged it for me.
I do not know if yours could be having the same problem, but that was my experience. Frustrating, to say the least.
Hmm... Could be the hardware i guess.. I know its not the cable though because i've only ever used the cable that came with it.
Have you tried connecting to the USB port directly off the motherboard? My connections were "sketchy" at best when using the ports of the top of the computer case. Once I connected directly off the MOBO, zero problems since.
Sloved!

Thank you for suggestions! My front USB connector is probably connected to some internal HUB, not going straight to the motherboard and wont work. Connecting directly to MB USB solve the problem. I am a little bit surprised... but whatever - M$ bull*hits. I spend couple of hours yesterday to find out whats going on. Thank you again!

usb connection with pc suddenly dead

Hello suddenly my nexus s stopped connecting with data with the pc it only charges, tried with 3 diffrent computers with diffrent os , no menu popping on nexus and nothing connected on the computer(like i didnt connect anything), i removed the battery left it for some time installed stock rom still nothing.It was acting normally for a second and the other it stopped any help appreciated!
Are you sure you're using the cable that came with the phone? I have an LG Wink featurephone here that uses the same connector at the phone end -- its cable will charge my Nexus S (using the computer, obviously, but also when used with either the LG or Samsung charger) but no USB connection happens when I use it. Only the cable that came with my Nexus S provides a USB connection when I connect to the computer. I guess there are pinout differences between the two cables.
If you're sure you're using the right cable, I would guess that it's gone bad if it doesn't work on any computer. You can buy an (overpriced) replacement from Samsung or maybe a cheaper one on eBay or at a retail store. If the latter, be sure the seller lists it as compatible with the Nexus S.
it happened with the original cable ppfff i dont know...
same problem

Hi
I have the same problem
I have no idea what the problem could be.
We are not alone with this problem: code.google.com/p/android/issues/detail?id=13553
Now installed stock rom as well but still the same problem.
If i starting the NS in the bootloader mode the phone is not recognized by the computer.
It would be great, if someone knows a solution!

Tried different cords, different computers and operating systems,, did cold start several times on phone (removed battery) still no luck, I am running totally stock
Curious do any of you have the Google Music Beta?? (maybe a over zealous rights thing?)
just tried it with a Win 7 machine that had never seen it before and it said it could not recognize the device,, me thinks that the MS device driver DB is messed up buy some recent Win update??

My phone charges just fine. And my USB connectivity was fine until I manually installed 2.3.4.
~I had usb connection problems after upgrade to 2.3.4 a bit different but I managed to get the USB back by formatting the SD card.

I was on 2.3.3 when this happened, i tried to flash 2.3.4 then and again it didnt work but the strange thing is that when i was moving the mini usb the first times up and down it was shown for a moment as a broken usb device.Then this stopped and was not shown at all on the computer and finally the phone charged super slow when connected to electricity
Beginning to believe that it is a physical prob with USB connector on phone. It seems to start/stop charging when wiggling usb on phone but no mounting. Doe anyone know best way to resolve , T-mobile but bought from Best Buy? so to Best Buy? FOR SUPPORT /EXCHANGE? suggestions?
I've seen loose connections before. My suggestion ain't the cheapest but the plug, on the cable end, shouldn't wiggle. I went to a corporate sprint store, the ones that actually have working display phones, and got their usb to micro usb data cable. The thing with that cable is when you plug it in the phone side, it goes into the jack firmly. You can almost feel the little locking tabs click into place. There should be no play or wiggle with that cable as long as there's no damage or abuse with the jack on the phone. IMO, that's a good data cable. It's never given me problems before.
Also, sometimes the cable is only wired for charging. A true data cable will be wired correctly and be able to both charge and transfer data. Usually the cables that come with the phone are crap quality. I don't know if my suggestion will help but it won't hurt to have a good cable for data transfer and flashing. The last thing you want is a flaky connection from a cheap cable when you're flashing roms. Russian roulette with bricking a phone in a worse case situation.
Did you try reboot the computer and the phone? How about a different usb port? How about unplug any other usb device in case it's conflicting for some unknown reason? It sounds like so many people with windows 7 are having problems. Usually always happens with a new os that's released. Xp, for flashing devices and programming different hardware devices, has never given of a problem. I have a small partition with xp on it just for that purpose only.
off to Samsung for repair for me...
After time on phone with them and a factory reset belief is that the usb connector is defective. BTW Best Buy just hands off to Samsung 1-800 #
So Back to a barely functional G-1 for a while, glad I could find it!
So is Samsung or the carriers replacing or fixing units?
My USB data died shortly after 2.3.4 ota update.
Wifi FTP is fine for data transfer but I want USB debug to work...
Shame on google and Samsung, this bug has been around for months.
no shame on anyone...
I went through a factory reset with Samsung on phone that isolated the problem to what is apparently a loose usb connector, nothing to do with software... only hassle is sending it in for repair, as` mentioned problem needs to be dealt with Samsung customer service (not carrier or Best Buy), they were fine on phone...

[Q] samsung usb connection kit proble

Iam using N 8010 with xxblj9 German JB firmware on it.
Recently i purchased Samsung USB connection kit ,when i tried usb and card reader its getting connected ,opening
my files ,then getting disconnected showing message USB unexpectedly removed.
Is this because of the firmware not supported or problem with usb connection kit?
Mathew
Unplug your device.
Download the latest version of Kies and install it.
Try again.
Turn USB debugging off if that doesn't work.
I can't say how close the 8010 is to the 8000 but I would assume that they would be much the same except for the 3g...
Anyway, I have a usb connector, 3rd party i found on ebay for around $10. It works fine with my usb sticks, not for anything that requires power, HDD and playstation controllers... I use a 32gb thumbdrive in it and can use it to read/write data to and from it with no errors... The one I got also has an sd card reader in it too and that works fine also...
Not sure what could be wrong with yours but would suggest going to store, playing with demo model and trying again... This will rule out the usb hub as the culprit or point the finger....

Are you on stock Jelly Bean.
This happens to me only with jelly bean,i tried on ICS ,works perfectly.
So i reckon the problem is with Jelly bean OS and this could be bcz im using German firmware which is for N8000.
Mine is N8010 ,this could be the reason.
Thanks for sharing your experience.
I will look forward for original N8010 JB release,hope that would be ok for the USB Kit.

Will the Samsung EPL-1PL0BEGXAR USB Connection Kit labeled for the Tab 10.1 work on a stock Note 10.1 (8013)?
yes it should all tab have the same connector, the connector has not much to do only certain pins combination change which give different functions
What I mean the connector itself is an passive device not an active device its like connecting the correct sequence of cable to complete the circuit, once it does that its up to the device and connecting device to communicate

USB 3.0 Problem

Hi!
Got my Note yesterday, now I got a problem, again. I can't get it work on USB 3.0 no matter what I do (I'm sure about this but I ask this anyway: am I right that SM-P905 have USB 3.0?)
Okay, to the problem:
When connected to USB 3.0 I don't have option to choose USB 3, I only got MTP and PTP
- I updated Kies 3
- I reinstalled drivers (from Kies)
- I have 2 USB 3.0 ports on my PC so not so many to test but:
USB 3.0 works on my Note 3 (SM-N9005) on both USB-ports, It also works well with my Note Pro USB-cable
Note Pro doesn't work (don't give even option to choose USB 3 mode) on any of these two ports. I also tried both ports using my Note 3 USB-cable, but still no luck
So any ideas?
ps. I got ASUS motherboard and I found out someones having similar problems with their Android devices. Reason was ASUS Ai Charger -utility, but I don't have that one never ever istalled on my PC. Oooh, and one more thing, I'm using Win 7 Home Premium (x64)
---------------------------------------------------------------------
Updating BIOS and reinstalling Windows did the trick, now it works like it should
What exactly makes you say it doesn't work? Are you completely unable to transfer data to/from the tablet to a PC, are you not seeing a difference between transfer speeds using a USB 2.0 cable vs a 3.0 cable, OR is the appearance of everything working there but you are wanting the USB 3.0 nag screen to pop up to give you an indication that you're indeed using USB 3.0 ?

When I connect Note to PC USB 3.0 port, pull down notification bar and click USB notification, I get ONLY option to use MTP or PTP. USB 3.0 is not listed there as option. I also transferred about <10Gb size file to Note and it took about 50min, which really is loooooong time..
Okay, here is screenshot about what I meant. Can you please say how it's in your tablet.

Same - Mine connects MTP and I can see it and transfer files but on my tablet I get a Icon in the top tray that says connected to USB 3.0
Same here, when I'm getting a USB 3.0 connection to my PC I'll get the 3.0 indication in the notification screen.
I can't get 3.0 to work with my rMBP but it works with my Windows 7 based workstation and I can definitely see an increase in file transfer speed to the tablet when the USB 3.0 cable is used in a USB 3.0 port. Just did a test from a hard drive on my PC to the tablet, 2.1GB file transferred to internal memory on the Note Pro in 1:18 using a USB 2.0 cable and 0:48 using the stock USB 3.0 cable so I'm getting about 45mb/s with 3.0 and 27mb/s with 2.0.
Okay thanks. Tomorrow I'll check again if notification bar shows USB 3 or not, can't remember right now (still got thought that not). I'll get back here and tell if it's working or not.
EDIT: Yup, no USB 3.0 connection, in notifiction area there is that standard USB icon and it's not saying 3.0
EDIT2: Is there some way to find out if Note charges using USB 3.0? Shouldn't the 3.0 be a lot faster on recharging than 2.0, but how I can know which one it uses?
Sent from my SM-N9005 using XDA Premium HD app
Okay, back to subject..
Does USB 3.0 affect anyway to charging speed? Like if I use stock wall charger with 2.0 or 3.0 cable?
What's your charging speed? I did test and from 50% to 55% it took 15 minutes and from 50% to 65% 45 minutes (which makes average 5%/15min)
To charge I used stock wall charger and stock USB 3.0 cable. I didn't use my NP while charging and mobile data / wifi was OFF
Can you please check how fast is your Note Pro to charge? I still can't make my note to work on 3.0 mode when connected to my PC and I'm trying to find is the problem on my PC or Note before sending this to repair
How about trying Gsam Battery Monitor and observing the charging characteristics that way. It will give you charging current.

With wall charher charging current is 1900mAh, which is normal I think.
Now, if I plug my NP to my computers USB 3.0 port, I get BSOD --> PC reboots and I plug again --> now it works, but still not on USB 3.0 mode. So it could be with drivers or something, tried again install device drivers with Kies 3 but no luck. What could I do? I don't have skills to remove all the drivers and start from clean table (any other way than formatting my pc and that's not gonna happer for a while )
Any ideas?
Okay, just tried with laptop (Win 8.1) and my NP is ok, it connected using USB 3.0.
Now what, if my external HDD and Note 3 works on my own PC via 3.0, what I can do to make my Note Pro work also??
Problem have to be with drivers or something..
Mine doesn't show the "Use USB3.0" option that my Note 3 shows, but it clearly says "Connected as a media device via USB3.0" in the notification bar. (See attached screnshot)
Also, it just copied 1.03GB in 16 seconds from my laptop to my NotePro.
Clearly they removed the USB 3.0 setting from the menu, and it is now done automatically.

I'd start with USBDEVIEW. Google it. Run that with no android devices connected to the PC. Uninstall all drivers related to any android device and reboot the computer. Then try again.
If that doesn't work, consider repeating that, rebooting and then updating the chipset drivers for your motherboard.
After that, I'm out of ideas.
Us Mac users have the same issue; the tablet is simply not recognized as a USB 3.0 device on my rMBP which is running Mavericks. It doesn't matter if I'm running windows as a virtual machine in VMWare Fusion or not so I'm thinking its at the driver level of Mavericks.

I updated them twice, just to be sure. I got 2x USB 3.0 ports on my PC.
My external HD and Note 3 works well with both of them. And Note 3 also works with NP 12.2 cable.
Just my NP wont work no matter which port or cable I use.
On my friends laptop NP 12.2 with the cable that came in the box works well, immediately connects as 3.0 device.
I think I'll quit with this. Don't have the knowledge find out where the problem is.. I thought maby BIOS update might help, but since everything else works fine, I wont do that because the risk of totally f*** up my computer.
But if anyone here got any other/more ideas, I'm listening

You said you had an ASUS motherboard, right? I'd go ahead and update the BIOS, it's pretty fool proof with the newer ones (which you have USB3.0, so it's a safe assumption that it's new enough.)
I also have an Asus motherboard, funny thing is, my Note Pro does show the USB3.0 indicator in the notification bar, but I'm copying files over right now via Linux and it's copying at 9.9MB/s. That's pretty horrible. Added to that, my Note Pro won't charge from the USB port on my computer, but it will from the wall charger. It has a big red X over the battery when plugged into the PC. So I'm not sure if that's somehow related.
Another thought about both of our problems, is that maybe the cable is a little loose or something is in the port-hole. I know mine was a bit flakey for a bit there (as in I would plug it in, create a folder... then tried to rename it and it said it couldn't access the device... I had to try it three times after unplugging and plugging it back in.)
It doesn't make sense though that it's a BIOS and/or driver issue if you also have a Note 3 and it's working through USB3. I know on mine, when I tried it in Linux (can't recall if I did under Windows), it was extremely flakey there too. The Note Pro just autodetected it, but still copied slowly. I'll have to try that under Windows as well now.

Yes, you may want to update your BIOS.
(For the record, I'm using an Asus N76VB with the factory BIOS, no issue).
Hm, maybe a silly suggestion... Are you using any type of USB charging setting? I know some of these Asus motherboards come with an option to overvolt the USB port to enable fast charging.

Not related. A USBport doesn't supply enough amperé to register as charging. Even my old Galaxy Tab 2 10,1 has that issue.

I have that issue with my Note 3 and even my TF700T since day 1. It's an MTP bug. And now since 4.4.2 I can't rename anything on my Note 3 without explorer.exe crashing. Different pc's, different OS's, different cables, no difference.

I did read somewhere that Asus AI Suite (program to tune up voltage or something for usb charging) can somehow do "harm" to USB3 connection, but I don't have that one even installed.

Well... I too see that red x on top but my tablet charges anyway (slowly byt still charges)
The funny thing here is like I said: My Note 3 works perfectly when plugged to USB3, but my NP doesn't like recognize that it's plugged to 3.0 port. It just acts like using 2.0. Same PC, same cable, different device.

Yeah, I know mine isn't charging because I watched, even after plugging it into my computer, it slowly go from 70% battery down to 65%.
When looking at what is hogging all the battery, it's the retarded Indexing service. I'm still in the process of seeing if there's a fix for that, but it really seems like it's having an issue (which would also explain why mounting it on the computer is flakey, since they could be trying to read the same file systems.) Oddly, my Note 3 doesn't have any of these issues (except actually mounting as USB3). In fact, I was starting to suspect my PC at work had crap USB ports, but it's just the stupid Blackberry cable (it only successfully charges the blackberry, not my Note 3 or anything besides my mouse that I've plugged into it.)
