USB port problems (device not recognized)

Well.. it seems to me that there has been an unusually high amount of people who are now getting the USB device not recognized error when plugging their phone into their computer. Myself included. I'm stuck on dj05 because of it.
Can everyone that's having this problem post what they've flashed and how? Or any other problems their having? Make sure to post what OS you are using, x64 or x86, stock cord or not, Samsung drivers version, etc. Maybe we can find a common theme between everyone having the problem, and figure out a way to fix it. Thanks!

Same problem. I was running DL30 with the Blackhole Rom. Just stopped working yesterday. Tried flashing stock, then DL05. Can't root, ADB doesn't see it, nothing. Can't mount either. Win7 64 keeps saying its a CD drive and tries to install the verizon drivers. Did that, still tries.

I thought considering I started the thread, I should probably post my configuration as well. I had no problems with USB until I flashed kaosinate. I'm sure this didn't have anything's to do with it but oh well. I also flashed the lasted kaosinate kernal. After that, I installed superclean with adryn.'s test kernal. Still nothing. If you look around, there are definitely quite a few reports of the phone being recognized as a CD drive. Adrynalyne reccomends flashing one of his new test kernals which has been reported by some to fix the problem. He says that he still has to reboot with the phone plugged in to have it recognized, however.
I an running windows 7 pro x64 with the lastest Samsung drivers. I only get the USB error when plugging the phone in while its In downlaod mode. Otherwise it is recognized as a CD drive. I guess this is what we get for flashing non stock firmware, Roms, etc. If anyone has any suggestions, feel free to post them.

Randomly came back...flashed stock DI01, then DI05, then DI09, then back to DI05. Working now...it must have finally wiped some bad code or something...

OK, so I went to root the thing...when the root rebooted, it didn't work. I had to disconnect and reconnect the USB cable to get it to recognize again.

Did you use Odin? Where did you get the files from?

Running Windows 7 64bit

I finally got it to recognize. But it will not recognize when i boot into download so i can flash with odin...

Wugs root toolkit for nexus 7 problem.

Hey guys, I am having a hard time making this program work for my n7. I have the n7 32gb wifi with 4.2.1 JOP40D and I put those settings into the program, went into developers mode in the device, put the device on usb debugging and put it in airplane mode. Anyhow, I am trying to back up all apps and I get a message saying "Rebooting your device" then a second later it changes to "Waiting for your device to finish booting back up.." Well my device isnt rebooting or anything. I try manually rebooting but that doesnt change anything. I even tried backup all apps System apps+data and it does the same thing. When I try to exit the program it wont even close, it just hangs so I have to go into task manager to end it. Anybody have any ideas on what I am doing wrong? I want to make sure I have a backup file as I don't want to brick my device.

Check your drivers. There is a thread here on how to do it.

Something similar happened when I rooted mine. First of all make sure you have unlocked it, its very obvious while booting if you have unlocked the boot loader because a big open lock will show at the bottom of the screen during start up. Secondly, and the thing that worked for me, is to change the toolkit to "Android *.*.*.* any" in the model selection menu. As soon as I did that everything worked perfectly.

Thanks for the help guys, it turned out to be my drivers.

Wug's root toolkit won't recognize recovery version??
Hello, I recently upgraded to Wug's v. 1.6.2 and every time I start to use it, it says I have an "old" version of TWRP, 2.3.blah, blah and it wants to install update to latest 2.3.blah, blah........only thing is, I am on the latest 2.4.1.0!!!! Why does it not correctly recognize my recovery??? Thanks in advance.

My buddy is having issues with wugs toolkit getting drivers installed. He installs them but then when he goes to unlock and root its as if drivers are not there. Any ideas? I have been trying to help him with this to no avail he is running windows vista.
Thanks in advance for any ideas

I've never installed Kies in my life, so I can't comment on it's functionality. nor am I stock...but before I rooted and started flashing, my Rogers S4 was stock.
I used the AT&T drivers to get it to connect in debug or MTP mode. Maybe they will help. You can find them HERE. click downloads or see all downloads and then EXE on the right for the USB Drivers...

still no luck

well I know those drivers work for fact. My Rogers S4 was running VLUAMDJ software...my computer installed some drivers but it didn't work...it never showed up. just like your symptoms. I uninstalled my existing Samsung drivers (which I downloaded when I got my Note 2)...reboot...install those drivers I linked you to, connected phone...detected right away and MTP started working as expected.
so you either have issues with your system (software wise), or it's a faulty cable. I'm going to lean towards the latter first. It's not the first time I've seen that. feel free to try another cable...also if you want...plug your phone in and take a shot of dev mgr and paste it so I can review...or PM me the pic if you prefer....

I thought kies had a troubleshooting mode. Have you tried that? It is referenced I the noob rooting video.

Here is pic for my dev mngr, I tried 3 usb cable, kies troubleshooting but still not showing up, when I plug my phone kies start-up but does phone does not show up in computer or kies.
Thanks for all reply, I can't send phone to Samsung for repair either because I bought from kijiji and Samsung warranty is not transferable

sorry forgot about the thread, my apologies. I haven't been using tapatalk as much recently, and that's where I used to check my participated threads.
I don't have those devices under ports if I have usb debugging on or off...weird. I'm on win8 x64...the only thing I didn't expand was Portable devices...I only have the two references in my dev mgr....
can you try uninstalling all the detected devices in dev mgr, and delete the driver from the system when doing so? then disconnect the phone, reboot, install those at&t drivers, then plug the phone in and test?
I want to recommend removing Kies before all of that, but not sure if you used it in the past, where it store the backed up data, etc..if you've never used it then please do uninstall Kies before what I mention above...
let me know.

I've installed those drivers on 3 different windows 7 systems this week and not one has failed to recognize MTP on the device first try...I even soft bricked my device a couple days ago, odin'ed back to VLUAMDJ stock, installed drivers on a win8 system that had never had an Android device plugged into it and wasn't connected to the internet (just installed those at&t drivers from a usb drive)...guess what...worked again..
It shouldn't work so easily for soo many people then not at all for you. I'm baffled at how easily it works for me even, and I've been trying to make it not work. I"m a technician I enjoy trying to break things to see if I can duplicate an issue, and fix it....and I can't duplicate your issue.
either something to with your USB port(s), or drivers (either mobo chipset or usb), or windows installation. if you have usb that are controller by a chipset like Intel then other USB that are another chipset, try on the other "bank" so to speak...you'd have ot know how to look for that if you had it though...or try it on someone elses computer with those at&t drivers. don't connect the phone until you install the drivers.
if it's not usb port(s), drivers, or the windows installation you either have 3 bad micro USB or you have a faulty USB port on your phone. or pocket lint preventing a proper connection (although I've assumed you've looked for that already)...those are the only things left.

[Q] PC does not show device

Hello,
I recently rooted my phone via Kingo root and flashed safestrap. Whenever I did that, the phone wouldn't show up on the PC as a device. Doesn't try to install any drivers, PC doesn't show that the device is even connected. Now I read somewhere, but I can't find it now, that safestrap disables the ability to mount the sd or use MTP. Well, I have uninstalled safestrap via command line, uninstalled the apk, removed root via Kingo. That didn't work. I just now flashed the MF3 stock image via Odin and it still doesn't work.
The computer can see the device in download mode, but not when it's powered on. It does not recognize it in recovery either. I have flashed the stock image twice now. With the bootloader, modem, PDA, and CDC.
I have installed the drivers from samsungs website. Uninstalled and reinstalled. I have used multiple cords. All of which worked before I rooted and flashed safestrap, and work currently on my fiance's S3.
It's not the cord, it's not the drivers. I'm at a loss.
I want to trade this phone for an HTC one but I don't really want to do it if it doesn't function correctly.
Any suggestions?

Nexus 4 lost computer USB data connection ability

at some point in the last 6 months or so, my phone lost the ability to connect to my computer- I've tested by uninstalling and reinstalling the USB drivers on my computer, using virtual drivers, etc. Everything I could- I even tested on other computers that it has worked on in the past. Nothing helps.
I then decided it must be on my phones end, so I went so far as to replace the USB connection board inside my phone and that doesnt even work.
I used to have my phone rooted, but that was lost at some point over a couple OTA updates-- Is there anyway I can restore root access on my device without using a USB connection, or does anyone have any ideas on how to fix the connection issue?
Thanks!

Did you check the cable?

Multiple cables as well. I'd do that before replacing the board!

Tried that as well. I've tried pretty much everything I can think of. the superuser app says it might be a kernal issue

Try the following
1)Boot into booloader and check in device manager if the phone is detected if so then go flash-all.bat 4.4.3( will wipe your phone,new phone factory)

Well,in that case...i don't know.Maybe you should go to a specialist.

Look for flashify, a app can flash recovery, once you have recovery, you can have root.

please answer below question
1. what os use on your PC ?
2. do you install others driver beside google adb and fastboot?
3. what version of adb and fastboot you have if you have installed before
4. you said you have OTA udpate from gogole or form the ROM developer?
note:
you need to install latest adb and fastboot. latest version is .31
if you have other 2 or more driver installed before, it may crash or mis regonice the phone, like samsung and google driver for Galaxy nexus which i facing.
