When connecting my i777 to my Windows 7 PC I get this error "Device driver software was not successfully installed" CDC Abstract Control Model (ACM)
then there is a red X next to Device unplugged
The window does pop up opting me to sync with windows media play and to view the devices folder.
Also, sometimes when I connect the phone, it tells me the device isn't working properly...is there a bug or something I'm not doing right?
I'm running stock, not rooted.
Did you install kies?

With your phone plugged in go through device manager under system and delete whatever shows up for your phone, including to delete drivers.
Unplug the phone. Delete kies. Restart pc and make sure you download the right version of kies, though, there are driver only packages available.
Then after all that is done plug your phone back in.
There may be some extra steps in there but better to hit every detail so you hopefully won't have to do it all over again.

I had the exact same problem as you. I uninstalled Kies and installed the drivers from here: http://www.samsung.com/us/support/downloads/at-t/SGH-I777ZKAATT#tab3
Then, renstall Kies, and things seem fine.
Hope this helps

For the past few months I've been having problems with my Wifi/3G Tab 10.1 in that it can't be recognised at all by my laptop or my spare laptop in any Explorer-type program or Explorer itself.
I've tried everything that I can think of to fix the problem and just when I thought I'd fixed the problem in that the USB Hardware eject icon is showing up for when you want to remove it safely, the drives aren't showing up now in Explorer or Q-Dir at all!
Frankly, this is bloody pissing me off especially as I need access to the device to recover some files from it, so how can I fix this problem (I can't wait to buy a Transformer Pad Infinity or its next version as the Galaxy Tab 10.1 must be one of the few Samsung devices that I don't like!) as it's got some ebooks and other files that I forgot to transfer to my laptop before I screwed up by deleting certain folders by mistake.
If you have toggled usb debugging with no results the its most likely a driver issue on your computer. An easy work around for now would be to install Airdroid to be able to transfer files off wirelessly.
As for the driver issues what exactly is "everything"? Have you made sure to completely uninstall all Android device drivers? If so how did you do so?
I would recommend using something like usbdeview to uninstall all Samsung and other android devices, then I would reboot and attempt installing again with USB debugging off.

When I previously uninstalled the device drivers, I did so via the device driver option (my OS being Windows 7) available via the Control Panel.
I'll try your advice as well concerning Airdroid and usbdeview.
Don't get me wrong, I love Android as a OS, but when it comes to viewing partitions via a computer, it's just as much a pain in the ass as it is to view an iOS device.
EDIT: I downloaded and am using usbdeview right now and it's saying that the Samsung Mobile USB Composite Device (in this case, my Galaxy Tab 10.1) is connected properly but has no drive letter at all.
Uninstall it using that program with the tablet disconnected, reboot the PC, verify that the tablet is not in USB debug mode and then reconnect it.
Failing all this, repeat the process but prior to reconnecting do a clean install of kies.
By the way, your frustration is understood but its not like the grass is always greener on the other side. I have a nexus 7 that has MTP broken right now due to the latest 4.2 update.

I followed your instructions and it didn't work the first time even though I used usbdeview to uninstall the drivers.
I then reinstalled Kies after rebooting and even though the drivers were installed properly, the device still doesn't show up in Explorer or Q-Dir at all like before.
I am at a loss as to how to help you further. If the tablet is running fine and USB doesn't work with or without USB debugging enabled then it is either a cable issue, port issue or driver issue.

I guess I'll just have to wait until I can get my other laptop fixed to see if I can recover the files from the tablet via Recuva.

Hey Guys,
I have had my note 2 for a couple weeks now and have finally decided I want to root/unlock it. I am running into some very frustrating problems trying to get the drivers to install. I have tried using Kies to install them, that doesn't work. I have tried the toolkit and that also doesn't work. Every time I plug my phone into my computer after installing the drivers (Yes, I have checked "USB DEBUGGING") it just continuously starts flipping back and forth between "connected as an installer" and "MTTP".
I am at a complete loss on how to get this thing connected to my computer. When I check the status on the toolbar it always says Samsung_Android = "failed" or "device unplugged". Device manager picks up the phone but there is the yellow warning box present and when I select update drivers it tells me they have already been installed and updated.
I first thought I was having problems because I am running windows via bootcamp on my macbook, but I have tried installing the drivers on 3 other PCs and each one will not pick up my phone. This isn't my first go-round with rooting/unlocking phones, so to say this is very frustrating is a complete understatement.
Is it possible I have a faulty phone or is there something else I can try?
Thanks for the help.
Go to control panel/system/about computer. Should show u what ur computers running. And on the left is advanced settings. Open it and go to hrdware. The setting on the bottom about driver installation, adjust that to only install drivers from windows if not on my computer. Un install all ur phone drivers, restart, re install, restart and u should be all good. Windows pisses me off. Lol hope this helps.

Just tried your suggestion and the drivers are still failing to download when I connect my phone. Any other suggestions? I may just take it to Verizon tomorrow and ask for another phone. I have never had this happen before.
Anyone else with suggestions? I may be taking it in to verizin today if I can't get this figured out.

I would un install all drivers reboot go to Samsung website and download the drivers or package for the divers for your phone then run the installer with out your phone being hooked to your pc then hook your phone to your computer see what happens . Then go and see in your phone in the status bar what type of connection make sure its not on the camera one I forget what is called but you want the one that says storage

SOOOO stupid......I had to completely restore my phone back to factory and the drivers installed finally. That was a terrible experience, but at least I can root and unlock now!! Thanks guys
I rooted my phone a while back with a one click root process that rooted it to a rooted version of the stock rom. Recently I recieved notification that Jelly Bean is now available for my phone and that I need to connect to my computer via usb to update. But, my computer keeps getting a "device not recognized" error. I tried to install Kies for the drivers with no luck, uninstalled the drivers from Kies and installed the others straight from the Samsung website with no luck. I have tried 2 different computers and three different usb cables, including 2 oem usb cables. I have windows 7 which may be the problem. Are there any work arounds like going to stock from my sd card? My phone is no longer rooted, but for some reason still has Superuser which i can uninstall still. I brought my phone to Sprint which the guy was really cool and informed me that its not the usb port on the phone and that odin is recognizing it, but odin on my computers doesn't even see it.

Did you have the Android drivers installed previously? I'm assuming that you're trying to install the drivers for the first time on that your computer and that you have USB Debugging enabled. I'll also be assuming you disabled driver verification, which can be a problem in some computers.
First you need to boot your phone normally, and plug it into the computer. Press Win+R to open the "Run" dialog and run "devmgmt.msc," which is the Device Manager. Look up the "Unknown Device" that is your phone and double click it. Click on the Event tab and check the Hardware ID in the drop-down box. It should look something like this (sorry mine is Android Composite ADB Interface because I've installed it already, but that's what it should look like in the end):
Now you have to make a new section in the driver inf. It should be in the google adt bundle and in the extras\google directory. The file name is android_winusb.inf. In the picture below my tablet is the iDeaUSA CT702. You need to add one of these sections in both the x86 and x64 section if you have a 64 bit computer. If not, just put it in the x86 section. The %USB stuff needs to match that in the Device Manager Hardware ID.
Now you should have a device called Android Composite ADB Interface or anything like that is fine.
It says there are no drivers and that there is no hardware id. All there is are device instance id. Im not quite sure where the driver.inf is located. This has been a pain for the past week. Hopefully we can figure this out. Lol.

I think there may have been something wrong with the rom. If i could just reinstall stock i think it would work. Just need to get the USB to read to the computer.

If you don't know where the driver is, then download a new one. I've uploaded the official Google USB driver to mediafire here: Mediafire - usb_driver.zip
You need to modify this driver, then when asked to select the inf file for driver installation choose the android_winusb.inf inside. After installation your phone should be recognized. Please tell me if there's any uncertainties you have.
Have you tried connecting the device with usb dev mode disabled? I know its strange but I've a few devices that use different drivers if the usb dev mode is enabled. I've also devices where I need to enable usb mass storage setting every time (settings menu or slide down notification). Also it never hurts to try a new cable, usb wires do tend to wear out and are very cheaply manufactured so they break inside with the slightest tug of the wire. I know most of this stuff is uber basic but I've made things much worse on countless occasions by overlooking simple stuff like this.

Good point. If you don't have developer mode usb debugging enabled, then there will be no "unknown device" as shown above in the device manager. Be more detailed about "no luck" please.
I flashed up to 4.2.2 the newest 2,2 Liquidsmooth rom, didn't like it, so I wen't to flash back to 4.1 jellybeans build 13. I wiped everything, from, factory, cache/dalvik 3 times and then flashed. I loaded it up and it was buggy, so I wiped and reflashed again, and like the last time I have no signal and my phone no longer connects to my computer. Everytime I plug it in it says installing drivers but it will never connect. I get a message saying there is nothing on my computer to detect my phone even though it could 20 minutes ago. I have an odin stock file I wan't to flash but can't as odin won't recognize it. It makes a sound upon being plugged into my computer and shows up under device manager saying drivers are all up to date but I still get nothing. I can still use twrp though etc. What do I do?
Good luck dude I can't even root my new note because of this issue

I feel lucky that I rooted my phone as soon as i got it and everything went successful. Because like 3 days later my phone stops communicating with the computer...
Thankfully I have a micro sd card so i can do flashable zips... But if I ever have to Odin back to stock or use Odin for anything I'm screwed.
From what I've read it isn't a phone issue is a Windows issue? But I don't know if that's true because i have yet to find a fix...

Thanks! Simple, but it worked for me, too. Took about 2 seconds to find it and install it.
Windows did need to update a driver first on its own so that it would have something to update. Otherwise you may not get the Update driver option when you right click the driver in Device Manager.
Something like this:
1. Connect the phone in the mode (phone on, or phone in download mode) that isn't working
2. Start/Right click Computer/Properties/Device Manager
3. Right click on Android or Samsung drivers that appear
4. Choose Update Driver, Browse computer for drivers, Pick from a list on my computer
5. Click on the most promising looking drivers that come up until one works

I had the same problem as everyone else. Odin would not recognize my note 2 (Windows 7) or acknowledge that it was connected. I got the correct drivers to load by going to USB options on the phone and checking Connect as: Media Device (MTP) while connected to the PC. Windows automatically installed the drivers. I then shutdown my device, put it in download mode, and Odin recognized it and I was able to flash.

Make Odin Recognize Note 2
1. Open Odin
2. Get Samsung Note into Odin Mode (on off state, hold down volume down, home, and then power button)
3. Plug in to USB
4. If it doesn't recognize your device, take out battery (keep it plugged in!), wait a few seconds and put battery back in
5. Odin should now see your phone under ID:COM

I even re-flashed the 4.3 .tar file using Odin and went through the entire process of re-setting up my phone...no joy.
Oh Android - why do you hate me so?
@jburchii,
You've probably done this already, but just making sure....Have you enabled USB debugging for your phone under developer options?
If not... you can find this in your system settings.

Use the factory USB cable that came with your Samsung Phone
Try another computer
