[Q] USB Storage doesn't show up in windows 7

I have not had this problem until recently and not sure what has caused it. My phone is not showing up when I mount my SD card. Also undetected by ADB. I have tried multiple cables, different computers, and also reformatted my computer and installed fresh drivers just in case. My phone does however show up in Odin and I can flash a modem no problem. I was thinking about wiping my phone back to stock and going from there, but I am afraid that will not fix it and I will be stuck at stock. =(
Thanks,

Had the same problem. Had to reload the drivers even though my other Epic was recognized just fine.

Same here, its' like it woked one day and didn't the next. I had 2 problems, one was the fact that only half of the usb jacks on the front of my desktop work (dumbass), and I had to re-install the drivers found on Samsung.com. My computer also will not recognize the sd card until you turn on mass storage from the drop down menu on the phone after the usb is connected.

What I did was turn on USB debugging, connected the phone in the drop down menu, then went int control panel>device manager> and looked for either "Other" or something in the USB connections. I found Samsung Android. I clicked that and hit update drivers from Windows Update. It took like 30 minutes to load all the necessary drivers then connected fine after that.

I have tried uninstalling/reinstalling drivers. I am pretty sure I have tried the update driver thing through device manager, with it saying I already had an update to do driver. I have also tried with/without debugging and also manually selecting use as a mass storage device. Just kinda weird it shows up in device manager, just ADB doesn't recognize it or as a mass storage device. I am starting to think it is something more with my phone as it doesn't show up on other computer and tried other cables. May just say screw it and try Odin.

You can uninstall the drivers, then let Windows Update find the drivers again. It needs 5 drivers altogether. My problem was similiar. It wouldn't recognize my phone with USB debugging on, yet had no problem recognizing my other Epic so was sure my phone was screwed up. After Odin it did recognize it but wouldn't after rooting and putting on a GB leak ROM but again the other phone was fine. Forced driver update and has worked fine ever since. Although one phone shows up as F and the other as E. Not worried as long as it works...lol.

I uninstalled the Galaxy S 64bit drivers but the uninstall option that came with the package. I plugged in my phone, it attempted to find drivers and said unsuccessful. I click, search automatically and it comes back with nothing.
Also it says it is Samsung CDMA Technologies.
Edit: I just tried manually updating the drivers by pointing to the driver location instead of using the provided installation. I see only 4 drivers installed. Samsung USB Composite Device, Samsung Mobile Modem Diagnostics, and one other I am unable to find the name of.

There is also a CDC driver.

I fixed the problem. In case anyone else runs into it, it's simple to fix. I was afraid to ODIN back to stock in case something was wrong and unable to root/cwm again, but I grew some balls did it and it's now working flawlessly. Must have been something messed up with the system files on my epic, that even a wipe and reflash from CWM would not fix.

Did you root and reflash your ROM and try it?

Yea, I rerooted and flashed my rom. Everything is working fine so far, along with my SD card and phone showing up on my computer. Before it was just showing up as Samsung CDMA Tech. now it is showing actually showing the samsung model number. So something happened with the phone before. Not exactly sure.

Glad you got it working. You were lucky Odin still recognized it.

[Q] USB not connecting to computer

So I can't get my s3 to connect to a computer. I have tried three different computers, two windows and one mac.I have also tried three different usb cords including the one that came with the phone and a brand new one I bought just to see if it was the cord. Have done a factory reset and tried everything with usb debugging on and off. My phone will charge but the computer doesn't recognize it. I have reinstalled the drivers twice on both windows computers and tried the Kies troubleshooting. I have also put it into download mode and Odin doesn't recognize it. When I plug it into the computer nothing happens, no sounds or messages saying something was plugged in. The phone does not have the option in the notification menu for usb debugging. I can use AirDroid to put just about anything I want to on my phone over wifi so I am not too upset about it not connecting but I would really like to put CM10 on it so I kind of need it to connect. I am using the stock AT&T rom. I rooted the phone awhile ago but then wanted to update so I went back to the stock rom and then updated. It would still connect to the computer after this update. Unfortunately I did not reset the flash counter so I doubt AT&T will do anything about it when it shows I have messed with it. I kind of think it is a hardware issue on the phone after doing all of this. Does anyone have any other ideas on what I could try?

[Q] neither KIES nor ODIN see phone

I'm currently running CM 9.1.0, so it used to work. The phone charges just fine, and I can transfer files to and from my pc via windows explorer.
In my system tray, the phone shows up as "Android Device". I think it used to show up as "Samsung Galaxy S II", or something similar. Did it change when I installed CM 9.1? I can't pin it down.
Kies and all the drivers I could think of have been updated, including those for the mobo USB. Phone drivers I grabbed right from this site: T-Mobile_t989_GSII_ADB_Drivers.
I've tried different USB ports on my PC as well as different cables. Nada.
Any ideas? I'm at the end of my rope.

Maybe the build.prop changed?

Anything other than stock won't be able to be identified on Kies. Odin try going into download mode maybe your phone will then show up on odin.

Download mode. That was the key. Thank you. That should have been obvious, but I'm not a regular twinker.

[Q] Cannot initiate USB data connection on GS3 (rooted, CM10; Win 7)

A few weeks after rooting and installing CM10 on my GS3, it stopped recognizing any form of USB data connection. It still charges from both computer and wall adapter, but I cannot initiate a data transfer or recognize my device using ADB.
I have tried:
three different OEM Samsung cables (from SG3/SG4 phones)
all the ports on two different Win 7 laptops
all the ports on an Ubuntu desktop
enabling or disabling USB debugging
with different combinations each time. No "USB connection" dialog has shown up on the phone, and no "new device" dialog has shown up on any of the computers. I know that I can get ADB working with a different Android phone (HTC Inspire 4G) so I know that my main laptop has USB ports that work and the cables I've tried work as well, so I'm left to assume that the issue is with the GS3. External visual inspection does not suggest the USB port on the phone is damaged, and the phone is only a year old, so I don't believe that is the cause.
Is there a system setting that I may have modified on the GS3 that would disable all forms of USB communication?
(The end goal is to get at least ADB working so I can try and recover some deleted files from the internal memory; I haven't found a reliable method that does not require ADB so I'm trying to get that to work. I know that transferring files on or off can be accomplished with the external SD card or over Wifi but that is not what I'm looking for)

Any suggestions from anyone?

I am not sure. Could be a software issue. I would try backing up your current cm ROM and try installing a fresh touchwiz ROM to see of that works, to rule out software issues. This could also be a android 4.3 issue. Could try stickmount or a similar otg app from the market.

I don't think any OTG app like stickmount will help; I'm not trying to connect devices to my phone. I'm trying to get my computer to recognize my phone (and vice versa) in order to get ADB working.
If I can avoid flashing a RAM I'd like to, because I'm still interested in recovering those deleted files. If that is the only thing that would help, though, then I'll do it. Any other suggestions?

Install Kies and that should get the drivers for the pc in place. Odin should recognize the device when it is in the download mode. If that works, then the pc to phone connection is OK and I'd look to software instead of hardware.
Or, if you boot into your custom recovery, either CWM or TWRP, you should be able to get ADB to recognize the device and issue commands including pulling the files on Internal storage. TWRP also has a file browser built in that might be useful.

I have tried uninstalling any Samsung drivers then using the SGS3 toolkit to install the official drivers, but that didn't change anything on the PC end.
Additionally, I tried finding my device while it was in recovery using ADB and there was no connection indication either.
I currently have CWM installed, but I didn't see a mounting option like I've seen for TWRP. Can I flash TWRP without a computer?

Or try this out: Download mode>Connect via USB>Let Windows download and update all drivers until the notification in the bottom right says it's ready to use>Unplug>Battery Pull>Boot normally>connect again. Voila! It works every time when it's being wonky and its a simple way that doesn't require a bunch of downloads!

installing insecure adb might help

Rebooting into download mode does nothing.
I believe rooting and installing CM10 means I already have insecure adb?

thanks
thanks

what next?

I have this same issue, in download mode, the device is still not connecting.
what is the next step? I have followed this thread and have the still have the same issues.

I can transfer files trough recovery mode only.

Yes, this thread title is weird. but hear me out. So the other day i was clearing out unused "Devices", that one thing with a exclamation sign. after i removing that, i tried connecting my redmi 5 plus (on system state) onto the computer, i was suprised that the phone only charges and the computer cant detect my phone on device manager. my phone also cant detect my pc.
i tried diffrent cables, diffrent port's, installing unnecessary drivers from diffrent sources, uninstalling usb drivers, other stuff that chatgpt reccomends.
can someone else find a mtp/solutions to this problem?
any help appreciated!

nvm i fix it by flashing a stock rom
