i can't connect my sgs2 to USB storage. when i plug in the usb cable to my computer and phone it will charge but nothing else happen. i had stock rom before but are currently using jug 4.0. i thought it was the rom so i downgraded to 3.69. still the same problem. i mean i can do anything with the phone just can't let my computer detect the phone. i tried to reinstall the driver, nothing works. please help!
Is your cable a samsung branded one? I had that same problem but with stock rom. I used an LG branded cable and the phone would connect to the computer and charge, but would not go into USB mode.
yeah, i am using the one that came with the phone, i guess i will try to use a different one. it was working fine before, don't know why it just stopped!
This has happened a few time for me. Sometimes the phone has only needed a reboot, the wire definitely plays a big role... I bought some cheap cables that didn't work at all... some of the older roms wouldn't show USB connected unless drivers were installed (kies). An issue I've more recently unveiled is after using an MHL adapter sometimes the USB will connect for 30-60 seconds before unmounting storage again. Hope that helps
My SGSII HercuDom needs more w00t. It always needs more w00t!
I had the same problem on a stock phone (purchased in late Oct from T-Mobile store in Arizona). I would connect it to the computer and it would charge but would not recognize the USB function (for data transfer or modem use).
Took it back to T-Mobile and they overnighted me a new one for no charge. New one works fine.

Cant charge or connect to USB
Hello, i just bought a samsung sgh i777 and when i try to connect it to charge it, wheter is on the wall or computer, a battery starts to flash, if i disconnect it, the phone starts as if you are turning it on. So far i've tried: Change the battery, change the charger several times, put factory settings and still the same problem, can anyone help me?
Thanks,
FS
I think my phone's usb doesn't work. I tried my htc usb cable and my friends samsung usb cable.
Both my comps and laptop won't recognize that a device has been plugged in.
USB drivers of gnex r installed...
You have to turn on USB in settings, mine doesnt automatically connect.

Wow! There have been a lot of these my USB port doesn't work threads lately. I hope this isn't a problem with the Gnex. Does it charge when plugged into the wall charger?
Yea, it does charge...
And I don't think it charges from the computer, only the wall.
And of course my usb debugging is on.
Maybe it's because I didn't root it properly?
I think it may have started after I rooted my phone...
How do I double check to see if my phone is properly rooted or not?
I used the Gnex toolkit btw.
Some custom roms have kernals that break USB. Are you on stock?

Could be that your usb charging board is starting to fail. When my board failed, the first symptoms was that the computer didn't recognize my phone.
I don't know how to tell if my USB board is failing.
Yes I am running stock.
And I tried connecting my phone in both camera and media device mode.
You should return it. This is most probably a faulty hardware issue.
I can't. It's craigslist.
Charging over USB works fine no matter the cable or the connection but it no longer will show up in Windows on any PC as a device. I tried flashing roms, changing cables, and doing the usb fix with Terminal listed in the sticky but it doesnt connect or will it know it's connected to a PC.
Can the port be broken so data no longer works but charging does?
its not the phone its the computer, try another computer

I have tried 3 which is why I wonder if my phone is broken, but it charges fine.
On all PCs the charge light comes on the phone with no problems but with all of them none of them detect a USB device being plugged in.,
Even in recovery if I do a USB-MS mount nothing happens.
Can the usb port break so that it charges with no issue but wont connect to a PC?

I think the solution to your problem can be found in this fix
The USB port on my Evo 4G will charge but won't show up as as a device on my laptop. If I hold the USB cable at an angle, though, it does show up. I think mine is busted, maybe that's the case for yours.

Yup. Last night I completely wiped it and had the phone format and set it up fresh.

Do you think the cable is busted or the phone? I have tried multiple cables on multiple PCs and nothing happens.
So then it is possible for the phone to be unable to connect but still charge fine?

Have you tried mounting when in Recovery?
It really sounds like your cable is weird. The power lanes are on the edges for USB, meaning that the port on the phone is probably physically fine. The cable, however, is vulnerable to damage on any one of the four wires.
If nothing works, then perhaps something internal is busted. What do you need to transfer from your computer? Perhaps you can do it by connecting to your computer through WiFi for mounting the SD card and adb?
Its your USB port on you phone, theres 2 pins or smoething broken inside your phone thats causing the problem. I had the same problem on my Evo were it wouldnt connect as a storage device and would go into car dock mode. I took it to sprint and showed them the problem and they replaced my phone. As long as you dont have any physical damage such as the screen being cracked you should be fine and they should replace it free of cost.
Make sure that your cable is not one of those charge only, car charger type cables. Typical car charging cables don't transfer data.

Yeah, that's pretty much it. If I wiggle it just the right way the computer will see something but it will go away as fast as it shows up. Doubt Sprint will do anything as the phone is a few years old, I dropped the protection plan, and it's rooted to heck.
I'll just keep it running until this fall and upgrade when the new Nexus line comes out.
Hopefully.

Many OTG peripherals require the use of a powered USB hub as the Kindle needs power assistance in the USB department. The app "Stick Mount" has rendered success with accessing some flash drives. Unfortunately not ALL flash drives are compatible.

i tried that app and nothing happens. it has a diagnostic tool also and it recognizes the flash drive.. but with no success.
if i need external power for a hub, then this entire thing is pointless.

If that app picks it up than a powered USB hub will probably make it work. For example....I tried using an optical USB mouse that was plugged straight into the OTG cable plugged straight into the Kindle. The mouse actually lite up BUT nothing happened besides that. When I obtained a powered hub it worked great using the same OTG cable with hub. What ROM are you using just out of curiousity?
I am using the 4.2.1_r1 AOSP ROM.
the thing is that I don't want to be dependant on elecricity. there isn't a plug every where. thank you for the time spent on my question
maybe should a nexus 7 and forget about it.

Well if you don't want to be dependent on electricity there is a different method people have used for a USB power supply. Here is a Youtube link that should explain it, or you could just get a Nexus 7 lol http://m.youtube.com/#/watch?v=BFEMh0ZYT5M&desktop_uri=/watch?v=BFEMh0ZYT5M

The sandisk cruzer sdcz36-004g

Only 4gb but I'd prefer to carry around a few on a ring than a powered hub, or that arrangement with the Y cable and the phone charger.
Plug it directly into the otg cable and off you go, I've played 720p video from the flashdrive with several ROMs recently, paranoid android worked great, TWA_priv's 4.2 also works but with some mounting wackiness sometimes.
USB mass storage watcher seems better than stickmount right now IMO.
Would the 8gb cruzer switch work? I am planning on buying an OTG Cable and need to specify.

Sure it will work, but you'll need a wired hub of some sort to mount it, either connected to an outlet or using a Y cable and a battery powered phone charger, which is hassle to carry, finicky to mount and not really OTG. I've never found a drive over 4 gb which was usable just by sticking it into the end of the otg cable, and most drives 4 gb or under don't work either.
The cruzer 4gb is my one and only recommendation I'm afraid.
I know this thread is a little old but just wanted to list the mini attache 16gig flash works with no powered hub.
Downside is that it only works till about 70% of battery. After that its not enough voltage
Plug it into the kindle, then plug in the flash drive.

Can you detail which app you used to mount it? I've tried quite a few of them but stick with USB otg helper and USB mass storage watcher.
Just got a brand new Samsung Galaxy SII T989 from T-Mobile this week, it really is a great phone, only I have a single problem.
The phone charges, it functions properly generally speaking (calls, texts, camera, wi-fi,etc...) but as soon as I connect it to my computer it freaks out.
It acts as if I were disconnecting and reconnecting the USB cable 2 times a second. I can hear the phone making the beeping sound it makes once you connect it to the USB every few seconds and in my computer (Which is running Windows 8 x64, just in case.) I can see the "Safely remove hardware symbol pop up and disappear a few times a second as well.
This is really frustrating... I love to take pictures and videos and edit them... I'd also love to copy some music over as well...
So far I've determined it can be the cable, bad drivers, or the phone itself, I just hope it's one of the first two.

Try re installing the correct drivers or switching the usb hub. If that does not work it's most likely the usb cable, swap it for a different one and you should be fine considering you bought the phone new.
Or you got a phone with a bad motherboard which would be crazy considering its new but that kinda sounds like the problem I had

Ok, does it get better or worse if you hold the cable with your finger when it is plugged in to the computer and phone and move it around a bit on the phone end? If so, I even got a Nexus 7 brand new from Google that the charge cable phone end was bad and would not make a good connect and I had to use a different cable and it works fine with my tablet.
If you use the same cable in your AC charger and on the computer then prolly not the cable.
It could be something in Win8 if it is trying to scan your USB port [like maybe a whacked anti-virus].
Have you tried a different USB port on your computer to see if maybe the one you were trying to use is bad itself?
If using a USB hub between your computer and the phone try removing the hub from the equation and connect directly to the computers USB port.

I am using a HUB on a Razer Keyboard that I've always used BUT now that you mention it my webcam had the same problem. It wouldn't work with the HUB on the keyboard. I'll try another USB slot (My computer's other USB slots aren't very accessible which is why I've hesitated to try another slot.)
I don't use anti-virus and yes, the cable works perfectly fine on the AC USB to Power adapter it brings.

I love you. It worked. It's the USB hub which doesn't allow much power to go through to the connected device. Thank yo so much.
