my computer does not recognize my epic anymore. I have the required drivers for it , but it keeps on popping up as an unknown device. I also made sure usb debugging was left unchecked. I have been trying to connect for a few hours now but still no luck.

What OS are you using on your laptop? If it's windows go to control panel and your programs add/remove (will vary depending on windows version) scroll down to "Samsung USB drivers" and click "uninstall", then reboot. Go to here and download the most recent usb drivers again. Plug in your phone, then install the drivers.
Post your results. Most likely it is not your phone, its a driver that has become corrupt on your laptop. Other possibilities are a bad USB cable or port on your phone.

Have you tried a different USB cable? Did you make any changes to your phone or PC just before it stopped recognizing it?
I had to use a usb hub with a power source for my laptop to see the phone.
Dell D620
Samsung Epic 4g
same thing on my pc. I keep getting USB Mass Storage Device Failed Error Code 10. started happening after the first push of froyo. im running Windows 7. very frustrating.
Epic thread revival!
I'm having a similar issue with my Epic. Both my laptop and desktop will recognize my phone as "Samsung CDMA Technologies" However, I can't do anything with it except charge. What's particularly bugging me is
A) Wired (USB) Tether won't work
B) Can't mount SD card through the phone
Laptop Specs:
Windows 7 Ultimate 64bit
Linux Mint 11 64bit (I'm having the same problems with Linux)
Phone Specs:
Epic 4G (SPH-D700)
Syndicate ROM Frozen 1.2
EG22 Moden
Genocide 2.0 Kernal
Here is what I've tried:
Toggled USB Debugging (both on and off)
Used Premium Micro USB cable in addition to stock cable
Uninstalling and Reinstalling drivers
used different USB ports
rebooted phone and computer
It should be worth noting that my phone seems to think everything is a-ok. Wired Tether app doesn't report errors, and when I mount SD card, there is no error either and the phone proceeds with the "USB storage in Use" message. My computer (regardless of which OS I boot) seems to think my phone doesn't exist, unless I'm doing admin type of things, such as flashing via Odin.
Normally, when I had my previous Epic (SRF 1.0.1, EC05, Twilight Zone Kernal), before it was stolen, Wired Tether worked perfectly, especially with Linux (connect as "AutoUSB 0"), and I could mount my SD card.
Suggestions?
Go to control panel and have it update drivers from Windows Update. Takes a long time to get them all.
I get the feeling it's more than a simple driver issue. I have the same problems with Linux, and linux has native drivers. And Windows Update is useless. It can't even find drivers for my fingerprint reader. Nevertheless, I will try it next time I'm on my laptop. Windows on my desktop is fubar.
I had the same issue with my pc.. I ended up using an old vista lapptop and everything worked perfectly.. sometimes these pc's just straight out don't work with these drivers.. wish I could help you out more man

Maybe dialing ##8778# and selecting modem mode under the usb section will help automtically install drivers.. see if that works, it helped me out for the whole epic to boost mobile process

Thanks, but not working
Have you confirmed that the port is open in your network ?
My kies will show a usb connected but will never actually share connection. But the wifi kies browser works

Did you try a different pc ?
Sent from my SPH-D710
tryd several pc's, and just about every trick i could google...still will not connect to device
I was also having days of trouble with this, but I can connect consistently now. Here's what worked for me on Win7-64:
Get yourself to a fresh start (uninstall drivers and Kies):
1) with your phone plugged in and USB debugging OFF (in my unprofessional experience, Kies will never connect if your phone's usb debugging is enabled), go to your Windows Device Manager. You should see either yellow bangs because your phone's drivers aren't installed correctly, or you'll have "SAMSUNG Mobile USB Composite Device" under USB controllers. Highlight it, click Properties, Driver tab, click Uninstall. Delete the device if it's still visible.
2) unplug your phone
3) If you're using the most recent version of Kies, I recommend downgrading to 2.0.2 because I read other forum posts about complaints with 2.0.3. Go to Windows Start - All Programs - Samsung - Kies - Uninstall Kies.
4) reboot
Now install stuff fresh
5) install Kies 2.0.2. I just googled it. Start Kies. Do NOT update it when you get the popup asking.
6) plug in your SGS2 (remember, USB debugging = OFF). You'll see a lot of typical driver installation bubbles. Go back to your Device Manager and confirm that you have no yellow bangs and you do see your SAMSUNG device under USB controllers.
At this point, Kies should already be connecting. I hope it works for you; it did me.
As an aside, Kies sucks. It's good to prove you have connectivity, install drivers, and to flash your firmware. If you actually want to sync Outlook contacts, Outlook calendar, and music, use MyPhoneExplorer (which btw requires USB debugging ON).
OK, did a search in this forum for "Found New Hardware SAMSUNG Mobile MTP Device" as well as "connect to Kies USB XP" and other variations of these. I believe I have tried all suggestions that I have found, but advice would be appreciated
Firstly, I have a Dell mini 10 running xp that my E4GT connects to fine through Kies. My E4GT is running StarburstROM 1.9.5 with LoStKernel 1.0.0.8+EXP
My old HP pavilion, running the same version of XP however just says over and over "Found New Hardware SAMSUNG Mobile MTP Device" and the new hardware sound plays about every 5 seconds.
After a fresh install of the most recent version of Kies, I tried
Different USB ports
Different cables
Making sure no files have extensions longer than 15 characters. (or was it 16...?)
Recovering the drivers through Kies
Downloading and reinstalling/reapplying the USB drivers found in various links here on XDA
Uninstalling and reinstalling Kies
Going to Device Manager, right clicking on the yellow triangle of the samsung mtp device and directing the computer to install drivers from there
Still I get an endless loop of Found new hardware. Unplugging results in "a problem occurred during hardware installation...etc" Any thoughts I haven't tried yet?
Make sure usb debugging is not checked in settings/development/applications.
what? i thought usb debugging had to be checked?
and either way it shouldn't matter if the phone is in download mode, correct? maybe i am wrong. i would assume that since he got it to work on a different computer it is not a setting on the phone and a problem with the computer reading the device's drivers.
Yeah, USB debugging is off. Tried it with it on just for giggles, but no joy. I may just have to accept that it won't connect to that compy. Can't get it to connect to Kies or even connect just for file transfer. Had same trouble with my OG epic. Maybe something about the original driver install from back then....
I'll try manually removing all drivers associated with the device and see if a reinstall from scratch (again) will work. I'll also check the .net version again, but I think I already did that. Thanks all!
My computer won't detect my Epic 4g when it's powered up, with either Debugging enabled or disabled. BUT, it does detect it when the phone is in Download Mode.
I have tried several different cables on all my usb ports. And the cable and port that I am currently connected with works perfectly on my other Epic 4g...
I wanted to root this Epic, but couldn't get computer to recognize it. When I plug it in when phone is powered up, I get no notification in the sys tray, nothing new shows up in device manager, no new drives show in My Computer, Odin doesn't recognize any devices.
So I put phone into DL Mode, plugged it in, and the computer recognized it, installed drivers, and Odin installed both Kernal-GB-3a and ACSRecovery1.0.0.5 successfully!
But when I boot the phone back up in order to copy the Superuser zip file onto SD card, same problem as before... Whether I click "Connect storage to PC" on phone or not, computer doesn't acknowledge.
Any advice?
(phone was on stock EL30 prior, fyi)
Thanks!

This happened to me with my 2 Epics, one connected the other did not. Had to reinstall the drivers...weird.

when you allow windows to automatically install the drivers, it doesn't always install the drivers properly. but when you manually install them, the installation process assures that they are ALL installed properly.
My epic asks if Iwant to connect to usb storage before the pc "sees" it

what you want to do is dial ##8778# and switch the bottom one to pda and the top to modem thats the problem trust me i tried installing the drivers and reinstalling it dont work... do this and its a gaurentee to work
Hello all!
First: I promise I searched the forums and google as hard as I could!
I'm running AOKP JB with CWM, although the problem was present on stock ICS from T-Mobile.
Symptoms: Computer and phone will refuse to acknowledge any connection (nothing shows up in Device Manager), except the phone will still charge. If I do the "remove the battery with USB plugged in" trick, the first time I do it, it will recognize an unknown device, but kies and adb won't recognize it. If I unplug it and plug it back in, it'll go back to not acknowledging any connection.
I previously programmed it (when I was still running stock ROM) via ADB via WiFi, but I need to be able to use ADB via USB. Besides, I can't seem to get ADB over WiFi anymore.
When I plug it into a different computer (Win7), it will, however, recognize my phone.
Earlier this year, before I ever tried programming via WiFi, it connected to my Win8 machine with no problem. I don't think it's a problem with the wifi setup though because the ROM was reinstalled and of course I've restarted ADB in USB mode in the months since...
What I've tried:
Reinstalling Kies
Reinstalling Samsung USB drivers
[^]Restarting the ADB server
Updating ADB
Trying different USB cables
Trying different USB ports
Toggling USB debugging
Toggling MTP mode
The UART thing from the dialer
Restarting the phone and the computer (of course)
Checking to see if my computer's USB drivers need to be updated
The android terminal command "setprop persist.sys.usb.config mass_storage,adb"
Pulling and replacing the battery while connected via USB
Crying in a corner
If anyone can help me, it'd be greatly appreciated! I'm all out of ideas and Google is no longer helpful =/
try to uninstall the drivers that are present anything samsung related to your drivers ... then connect the phone and let the process do its thing if you have the samsung drivers saved on your PC and the drivers still aint working update the drivers and then manually click where the drivers are to install them and hopefully it will work and when you tried MTP is it the only option it gives you no storage or anything ??... and is usb debugging on when you are trying all this ??

I tried on my work computer that didn't have any samsung drivers and when the "unknown device" dialog popped up it didn't do anything or install anything, nor did it show up in Device Manager. Unplugging and replugging it back in did not reproduce the dialog box. Togged USB Debugging and still no dialog box saying it recognized it.
The thing with the samsung drivers is that they're self installing so even if it popped up in Device Manager, I wouldn't be able to manually update the drivers =/
I tried MTP both with and without USB Debugging, although it also gives the option for PTP.
At this point do you think I should unroot and go back to stock? It's not been recognized on three computers now! =[
Are you using the stock cable? My computer wouldn't recognize mine without it.

Both the stock cable and a generic cable.
Similar problem
Similar problem as the OP. And hi guys, it's nice to be on these forums.
My device, when I plug it in using the stock cable, doesn't even charge. It doesn't show up in device manager, nor does it give me a notification, or say it's unsupported and bear that yellow icon. I have tried using different USB ports, I have tried the toggling USB debugging, I have tried restarting phone, computer, and taking out battery. I have tried that PDA/MODEM dialer trick. I am using 4.1.2 Jellybean, not rooted. (that WAS my goal,, until I hit this roadblock) I have not connected it to the computer in the past, it's relatively new. I'm thinking the cable is bust.
Any suggestions would be appreciated. It charges fine through a wall outlet plug, be it generic or stock.
so guys ive come to a conclusion i think its something in the samsung usb cables try getting yourself a blackberry usb cable , TRUST ME !!! ever since i got my phoness etc... tablet and yadi yadi samsung usb cables have always seemed to give me problems i think its because they are multi data/charging cables and when using the blackberry usb cable i have never ever once encountered a problem with any of my phones sd/storage problems do yourself a favor and pick up one of those cables and you will be golden !! if not then i guess im the only lucky one :LOL here you go http://www.amazon.com/Blackberry-Travel-Adapter-Micro-Cable/dp/B004VMVSYK/ref=pd_sim_cps_2 5 bucks!
Edit also one more test boot into recovery and click in the advanced menu and see if mount usb works for you in recovery mode ??
FIX (try using a generic cable)
I actually solved it on my own! After borrowing a generic cable from a friend it booted up! The Samsung cable was just not doing its thing.
yeah im telling you those cables they provide are JUNK!!! i only use my samsung to charge because they do that well but data they are str8 CRAP!! glad you got it up and going
OP
Hope OP will have the same luck as me...pray to the Android gods...
