[Q] What Is CDC Abstract Control Module?

I am trying to re-root my Epic after flashing to stock so I could take it into Sprint for repair. I plug it into my netbook running Windows 7 64bit and everything seems to install fine except this thing called "CDC Abstract Control Module ACM". It seems to find the drivers fine and even gets to the place where it says "Installing Driver Software", but then it hangs forever. I tried just running the CWM One click root, but it says "Phone not connected".
Anyone know what this CDC is and how to make it install? I have tried a few times doing system restore back to before I installed the Samsung drivers, then started over from scratch. But, nothing seems to work.

For the oneclick root make sure your phone has usb debugging enabled

mine hung on that too... wish I still had an old copy of the drivers, I swear they changed. Either that, or one other thing is that when I did the same as you about a month ago, I hadnt installed the Android SDK yet... come to think of it, idunno why, I THINK we still need it, but maybe not. Whenever I get issues with drivers installing, I uninstall them, reboot PC, reinstall, reboot PC, plug in epic, let it install drivers till it hangs, then quickly pull out then re-insert the USB in the phone and it sometimes will trip it up and complete the install. Also, now that I think of it, I was having issues installing drivers with the epic running a GB leak, as soon as I Odined to EC05 (using a different PC) they seemed to install fine. Hmmm... just reread your post, coffee THEN post, thats a good tip, anyways, maybe try the different ports on the PC, etc... I think the drivers are the biggest ***** of the whole process... everything else works pretty easily.

Weird I had the same problem I just unplugged my phone restarted my computer and phone and when I plugged it in I had not problems....try restarting both...also what method are u using to root??? And are u on EC05???

I had the same problem when I installed the drivers. Fortunately, I watched one of qbkings videos (where he talks about replacing the USB cable). I bought a new micro-usb cable and have never had a problem since. So really, the thanks goes to qbking for the great vids.

[Q] SAMSUNG Mobile MTP Device: Failed!!

My Samsung Galaxy S2X was working fine after the ICS update, but since two days I,m unable to connect the phone to my laptop. It tries to install the software automatically and after a while it give out an error saying that Samsung Mobile MTP Device failed. Earlier, the phone directly gave the option in the notification bar to connect as an USB storage but now it shows up Connected as a Media device.
I've tried every option available, from deleting files with 16 characters to re-installing Kies and the USB drivers. I tried connecting the phone to different computers but the problem still persists.
Another issue after the update was that the Bluetooth transfer rate is very slow with ~30kbps transfer rate which earlier in GB was 3Mbps+.
I'm wondering if its got something to do with the new ICS update or am I the only one with this issue? The device is on stock ICS and is not rooted.
Thanks for any HELP...
EDIT:
Solved the problem by doing a factory reset.

Update -*> Uninstalled everything, re installed still didnt work, updated Kies, still didnt work
I tryed the debug USB mode still didnt work
i Tryed differents usb cables
Tryed Differents usb connections
Still doesnt work !!
I dont know if theres any issues with the fact that I have a non-legit Windows 7 tho...
If anyone else got any ideas please share

Uninstalled the divers, deleted registry entries and re installed the drivers.Hate to say that it still won't work.

Which system? Windows or android? and what do you mean by "restoring"? Factory settings?
I have been having the same problem for 2 months now. I don't know what's wrong. I have tried EVERYTHING! Nothing works!
I even installed the drivers while the phone is turned off, turned on with debug mode and when battery is taken off while connected: the OMAP4430 drivers: and still it didn't work, lol. I don't know what the hell is wrong with that f***er, lol? It won't give in!
I removed all Kies with all drivers many times, like 6 or 7 times, connected the phone to pc while it's off then turned the pc on, changed cable, usb port, tried different computers, tried this *#7284# thing, etc... The only thing i didn't try is black magic and voodoo! Or maybe i should try hypnosis? Or electric DC shock?
Anyway, if you have found a solution, please let me know

Wow...2 months is quite some time. Please do a factory reset on your Android by going to settings-> backup and reset-> factory data reset.
Your phone should reset back to factory settings and you're good to go.

If you are rooted use Titanium backup else you may have to re download all the apps.

USB connectivity issues

ATT Galaxy S3
SGH-i747m
4.0.4
kyanROM 1.3
I am currently unable to connect my phone to a PC or MAC using the usb cable. I have tried just about everything I can think of with no luck.
what I have tried so far is:
restarting my computer and phone
different computers mac and pc.
different usb cable
uninstalling and reinstalling samsung drivers from PC
tried switching from mtp, to ptp, to adb, using phoneutility (*#7284#)
pulled battery
wiped cache partition
fixed permissions
I even booted the phone into download mode and connected to odin.
I see nothing.
any ideas? I am at a loss. I cant find any info or similar case.
edit: i also tried downloading kies and using the connection troubleshooting utility.. no luck
usb debugging is on but tried with it off as well.

I've been having the same issue on my Win7 home premium.
The phone is charging but can't see folders.
It works on OSX as a Camera though.Click on "Connected as a media device" from the pulldown menu and select "Camera", youll also need a program on OSX. Go to
androidDOTcom/filetransfer/ (i'm under 10 posts so probably can't post links)

Part of the problem is I am never getting the "connected as media device" message.
the phone only charges when connected to a computer...mac or pc

Try using a different usb cable. Something pretty short. I've had many a cables stop working. Also try a different USB port on the computer.

I am thinking it is my phones hardware at this point.

did this problem started since you flashed Kyan rom 1.3 cause I had the same problem a few weeks ago and I recently flashed the latest CM10 rom and everything works fine now. Does your phone charge when you plug it?.

My phone charges when I plug it in.
I can't be sure if this only happend after I flashed kyanROM 1.3.
That is definitely something I did since the last time it was pluged into a computer.
Maybe ill just flash cm10.

it looks like a driver issue to me! do you Have the snapdragon toolkit install on your computer? If not you can find it ther: http://forum.xda-developers.com/showthread.php?t=1746665
try the first step uninstall your driver and then install them using the toolkit
If you are using your front usb port try switching to your back usb port sometimes devices don't like the front usb port

Sounds like it may indeed be a problem with the phone's hardware. You might want to try taking it into the store to see if they can reproduce.

i re-flashed my phone using an old backup from when i knew usb connectivity was working,
still not working.
Brought the phone to an ATT device support center while on stock rooted rom.
They didn't realize the phone was rooted and they couldn't re-flash my phone without usb connectivity so I got it replace.
I am going to run stock rom for a bit... maybe until the official jelly bean release.
then maybe ill go back to Kyanrom or cm10... any suggestions?
Ilso I am not sure what created my usb issue.
I think it was my regular use of an old iPad power brick.
I am going to only use the stock charger from now on and hope that problem doesn't come back.

Had the same problem, but my work machine has never once gave me a problem, the one at home does this exact same thing, it maybe a phone hardware problem if you see it doing it on another machine, but I dunno, only reason I haven't fixed the home issue is, I do NOT want to re-install win7, my linux box see's it perfect every time also. I read somewhere in a forum, that it is a samung/microsoft driver bug. It is stored in the registry somewhere, what I saw was I had it working perfectly, then I plugged in my MyTouch to push a stock rom onto it, and then the next time I went to plug in the SG3 the problem started. Windows acts real stupid when you continuously keep plugging in different devices all the time. But then again, you said you tried it on a mac. Humm! Again, this is my opinion only.

same problem i have with no solution need help also please
same problem i have without any solution i need help please

Had the same problem, but with a brand new SGS3 with the stock ROM and cable. Plugged in my Nexus 7 cable instead and that works for some reason. Will bother best buy about it I guess.

got the same issue. tried to sync some files over from the gs3 to my laptop and it only charges the phone, does not recognize it . tried several cables and tried on my desktop, nothing. now im in search cuz this kinda sucks. i flashed CM10 ROM2 and it stopped working for me after that, tried restoring back to rooted stock TW but nothing still. still looking for a fix.

One thing I noticed is that all the computers where I'm having issues are running win7. One win7 home premium and the other win7 pro.
In the office I have XP pro and it recognizes the phone with no problems.

Kies won't connect to phone

My Mac won't connect to my gs3 using Kies... Yes I have drivers installed, you switched my usb cable to both usb ports, used media usb mode and camera mode, ticked and unticked usb debugging, I've done everything except factory reset.. Called Samsung and they were no help......... Anyone? I Bueller...... Bueller....... Bueller

I had to try a few different USB ports on my computer before I could get it to connect. Oddly it connected perfectly first time with Kies via WiFi (Settings -> More Settings -> Kies via WiFi) - but of course you can't update that way.

Ok, so ive downloaded and installed the latest drivers, enabled usb debugging, allowed unsigned apps etc. but whenever i get to the point of running motochopper it gets stuck on "daemon started successfully". ive checked my model number and its the correct device to be able to root but i cant get it to go past that message. Am i missing something? Ive tried following several guides on rooting the s4 with motochopper and i always end up in the same place. Ive tried rebooting the phone and my pc several times. so i dont know what im missing
UPDATE: so i just tried it again and it says that "'adb is not recognized as an internal or exterbal command, operable program or batch file."
i get this error when i run the program as admin. If i run the .bat file normally it gives the previous error

[Q] MTP Driver Install Fail

Hi all,
Got my new S III on Jan. 1. Love it. Gave me an opportunity to use my old Cappy to experiment with. Flashed a couple of ROMS already and really love it. OK..so here's the problem. The only thing I have done with the S III is root it using the QCOM Toolkit. When I downloaded the drivers and plugged in phone it said that if a device number was showing that all drivers had installed. Don't really know if the MTP driver loaded at that time or not...but the device number was there and I proceeded to root the phone. Now when I try to connect to PC I get the dreaded MTP driver failed error message. Did a TON of research on this and tried EVERYTHING...still no joy. I am running Windows 7 Home Premium and even tried using my XP Pro machine...still no joy. Would love to flash a ROM on the new S III but no way to copy to SD card without PC connection.
Phone is A T&T SGH-1747 4.04 Version.
OK to reduce the number of "have you tried's" I have: tried various cables, uninstall reinstall Kies..Kies driver repair, uninstalled/reinstalled all Samsung drivers. Tried the MTP/PTP toggle idea. Plugged in with USB debugging ON and OFF. Sooooo tired of getting the MTP USB Device Driver failed message!!!
Any new ideas out there?

Thanks Moe. Yeah I was afraid of that. Just got all my apps restored. Oh well. Well worth it if it works. Thanks again!

Factory reset is the only option that worked for me, and I tried everything you listed above. Also, based on prior posts, I plugged it into my computer before I signed into my google accounts.
