I've tried everything I can possibly think of. I have an Asus Laptop with Windows 7 64 bit and absolutely cannot get my Epic to be recognized. I've uninstalled and re-installed the driver more times than I care to mention. I've tried mounting the device to no avail either. I've tried plugging in the phone into each of the USB ports on the laptop to no avail. I need to get the computer to recognize the device so I can get odin to recognize the phone so I can flash back to stock. Right now it doesn't do so. Does anyone have any ideas of what I can do to get this up an running?
Try installing the 32-bit drivers even if you're on a 64-bit computer....
The same issue comes up. It says that the drivers are not successfully installed (even though the installer goes through) and it says "Unknown Device" over and over.
Are you removing previous drivers?
then rebooting before installing new drivers...
also are you using stock cable?
if so buy a new cable you can get cheap ones online for like a dollar just search micro usb cables
Yes, yes, yes. Does the cable really make that much of a difference? I saw that people have had issues but I mean it charges properly all the time so I figured it was ok to use.
Absolutely!!!!!!!!!!!!!!!!!!!!!!!!!!!1
That cable is worthless get a Blackberry cable they are very durable and dependable.
i was having problems also..... all because of the cable.
I'll probably go buy a cable from Walmart, order a cheaper one online from Monoprice and return the other just so I can odin my phone...I really hope that's the issue though.

does it keep looping "unknown device" in the corner, almost like you unplugging and plugging back in repeatedly?
ifso try cleaning the contacts of the usb port on phone and on the small end of the cable.
if not then try totally uninstalling the drivers you installed and if possible when its saying "unknown device" open the device manager, r-click then unistall in there.
USBDview has always been able to dig me out of the home when ive had usb related driver issues... just run it and delete/uninstall anything samsung/android/adb etc related, reboot pc and phone then try again...maybe even redownload the drivers

update (you replied as i was typing): one bandaid for the cable you could try for now is to take a needlenose pliers or something and slightly squish the micro end to try getting a tighter fit.... i had to do that to the cable i keep at work.
You can always just download kies. That's what I did. When I was trying the standalone drivers I had trouble. Installed kies on both of my laptops and coding works beautifully everytime. And I seriously think you guys are ill. Its a cable... its digital. It either works or.it doesn't. I use my samsung wire exclusively. Its thin and I like contour on the plug. Both cables have worked flawlessly on both of my epics.

You are wrong.
Cables can have breaks in them which give them intermittent connectivity. Also, since this cable has several (5 I think?) single strands of wire in them, a single wire could be screwed up causing this (or the pin for a single wire on either end) That would still allow it to charge, and partially be recognized by Windows, but not allow it to fully communicate causing this problem.
I have a cable that I only use for charging because it has this EXACT problem. Another cable works perfect, but this particular cable gives me the unknown device.

Right.. so it either works or it doesn't lol if both cables are in perfect working condition then there would be no issue. Its all preference. I personally use a blackberry micro usb cable. It locks in to the usb port on the phone better. Just so im not paranoid about the wire coming off while flashing... cuz thats bad lol

I didn't articulate myself clearly, but that is my fault.
If a single wire inside the cable is broken (for the sake of simplicity let's just say it is the RECEIVE cable - from the device to the PC). The PC can recognize that there is a device there, but because the device can't talk to the PC, Windows can tell there is something there, but has no idea what it is since the device can't talk back to the PC. Also, in this scenario the cable would charge just fine since those individual lines are intact.

To quote u "Yes yes yes" it does make ALL THE DIFFERENCE... I had the same problem and made serveral posts about it when the phone 1st came out, I tried everything... Uninstalled/Reinstalled/Rebooted many times, Manually deleted the folders where the drivers are held then Re-installed, Installed Kies (which is a P.O.S. and was a BIG WASTE OF TIME imo.) I tried everything and just about gave up until 1 day i looked @ my roomate and asked him 2 let me borrow his cable to his cheap cricket phone 2 see if it would make a difference.
Well it worked... Get a new cable, if you've done what ive done and it still doesnt work, its the cable and not the drivers
I've done just about all I freaking can on this as well.
I've installed, un-installed, and re-installed the drivers. I'm running Windows 7 64 bit on Bootcamp.
I've used USBDView, I've uninstalled all of the connected drivers. They get re-installed, but the phone keeps keeps coming up as an Unknown Device. I try and locate the Samsung USB drivers directory, but it keeps coming up as Unknown.
Does anyone know specifically what directory I should use choose when trying to manually link the driver in Device Manager? I'm having a ***** of a time here.
Anybody have any ideas for me? Thanks.
I had the same problem. Buy a new cable from monoprice. The second I bought a new cable for my 64 bit Asus laptop it worked.
Trust me, buy a new cable.

I had the same problem. I didn't follow directions to solve my problem in Odin. I had to start Odin and plug my phone in and quickly put the phone into download mode. I did that a few times and finally got it to recognize. With Syndicate, it now recognizes every time. I say that now. LOL
This is how I fixed this problem. After doing all I could think of, uninstall, install, system restore, nandroid restor to when phone was being recognized... all these didn't work for me. I still got the same unknown device in device manager.
The fix: with samsung epic drivers already installed. Turn the phone on, plug into your computer. Let device manager find unknown device. Power off the phone. Boot into recovery. Pc will recognize your phone as samsung android device. Reboot your phone and you should be good to go. Hope this works for the rest of you. Good luck.

Isn't the original issue that the driver install fails? not that the device isnt being readed?

ive had the epic since the day it was released and have had an impossible time getting my computer to recognize it on a consistent basis. i have no idea whats going on. when i first got it i downloaded the samsung drivers and installed them, hooked up my phone and nothing. the computer tried to install drivers but consistently failed. the next day i tried again, did absolutely nothing, and it recognized my phone and i was able to root and everything else. since then its been hit or miss, one day it will recognize it and then it wont for a week, even without doing a god damn thing.
recently i dropped my epic in the snow and it fried the radio, i brought it to sprint and told them the radio just quit working and they gave me a new one. now im having the same problem, i cant get my comp to recognize the phone. i installed the samsung 32 bit drivers and everything, but still nothing. i hook up my phone and it either tries to install more drivers or does nothing at all. I want to root my phone and throw some roms on here, but i cant seem to figure it out. my buddy has a captivate and said he read a post in those forums of some guy having the same problem and a solution but i cant find it. im told its a windows 7 32 bit malfunction of some kind.
sorry for no capitalization/ punctuation and poor grammar but im in a hurry to get to school and i wanted to get this posted before i left.
please help, this is pissing me off.
thanks,

Have you tried completely removing the drivers and reloading them?
+1 uninstall/reinstall drivers. Make sure phone is not connected when installing drivers.
Also make sure you have the usb cable unplugged from the pc until you are ready to do something. I found that if you leave the cable plugged into the PC at all times (and unplug/replug at the phone end) it makes it more likely to not detect. Leaving the phone end plugged in and plugging/unplugging the PC end made a world of difference for me.
Reinstall windows. It's almost funny how often that corrects weird driver issues.
Try using the usb cable and phone on another computer and see if it does the same thing. Also try using different usb ports, alot of times the front usb ports are underpowered and will give you issues when you try and mount the phone.
Sounds to me like the cable. IMO the only thing the stock cable is good for is charging on my nightstand. I bought a $2 cable off of eBay that works EVERY time.
I had the same exact problem as you! Just have you tried connecting your phone to one of the USB ports on the back of your computer?
Use the USB ports on the motherboard on the back. Create a new profile for connecting the epic and load the drivers in that Profile. If it fails to recognize, try another port. Make sure you are installing the drivers on the new profile you created through User Accounts and then plugging your phone in. This should fix your problem.
i had the same issue with home premium (also win7) i had to reinstall the drivers before everytime i plugged my phone in.
however, since i put a new rom on it (bonsai 2.0) i havent had this issue.
i have tried uninstalling and reinstalling the drivers numerous times. i rarely ever have the cable plugged in when im not trying to use it to connect to the phone. and my computer only has 2 usb ports on the side of my laptop, so i dont really have many options as far as that is concerned. not sure what else i can do.
Reinstall windows. It is incredibly easy.
+1 for the reinstalling of windows - obnoxious as it may seem. I have a dinky old laptop that I installed Vista on just to do work on my Epic. I can use any cable (stock or my Monoprice.com special) and any port on it to connect to my epic. My Win7 desktop, however, won't to this day recognize it.
Some people have reported success using the drivers that come with PDA.net , too.
Many people are scared of reinstalling windows. They think they'll mess something up. Just backup everything you don't want to lose and you'll be fine. Windows installs, and especially Windows 7 installs are incredibly easy. They basically install themselves. At work, when computers come back in from our stores with problems, I usually delete the junk, copy the hard drive, and reinstall windows. Unless hardware is dying, it damn near always fixes the problem and takes a whole lot less time than trying to troubleshoot some of windows' weird conflicts.
Also, reinstalling windows on a semi-regular basis will get you to build good habits about backing up and organizing your files.
So I'm attempting to root the Continuum, but for some reason the phone won't effectively connect to Windows 7. For example, when I hook the phone up to my Samsung i7 laptop, all the phone does is charge. It doesn't even ask me if I would like to use usb storage or anything. The computer also doesn't recognize the device. Any ideas? Thanks!
A couple questions first:
- Did you install the Continuum drivers?
- Does your phone bring up the USB connection in the status bar?
- Does it bring up the Verizon VCast website on connection?

1. I likely did not install the Continuum drivers, and I have no clue where to get them. I'm assuming Samsung's website, but it's a bit hard to figure out and navigate...
2. My phone does not bring up the USB connection in the status bar.
3. When I go to the browser, it brings up the Verizon website with news, etc.
It should probably be stated as well that this phone is not activated. I am using it on wifi only for the time being because I traded it with a friend for another phone.
Alright, so I've figured it out. Strangely enough, I was just using a generic USB to microUSB cable, and I actually needed to use a Samsung cable. Weird, right?

So...now that I'm rooted, how in the world do I install a custom rom? I saw that there's a ClockworkMod Recovery out, but what does "Odin" mean? I'm coming from an LG Optimus V and have extensive experience rooting and installing custom roms and recoveries, but I've never heard of that before. Thanks again!
First, we dont have much for custom roms on this phone. The couple we do have contain fairly well written "how-to's" for them.
Second, if you are not sure, do some research and find out as many answers with the vast pool of knowlendge at your fingertips (the interwebs) as you can. There has already been a swarm of questions asked, and I am sure the answers may already be there for you.
I am waiting for the update and Froyo roms to come out before I bother with custom roms, but I am not holding my breath for that. I will probably be on my next Android phone before I will bother. Modding it up with Widgetlocker, ADW Launcher, and some other goodies at the moment to tide me over.
I had this same problem today. USB mass storage wasn't working, adb wasn't working. I wasn't using the samsung cable, but I can't see how that would make a difference, as the cable I was using has worked for literally a couple dozen different phones from different manufacturers - including other samsungs. I had the samsung drivers installed.
The owner claims that only media sync works on his computer as well, and that usb mass storage has never worked. Anyone have any ideas on how to fix this?
i am also getting this problem. as far as i know i am still using the samsung cable, as normal micro-usb cables dont fit in the continuums port. ill look for another one, but this is quite odd. what i have done (all windows 7 64 bit):
drivers uninstalled
drivers installed
lagfix on
lag fix off
factory reset (within adrenalyne's rom)
i am going to try to transfer the stock rom via bluetooth and see if that works
edit: turns out that isnt possible without odi recognizing the device, which it doesnt (not even in download mode). this is very peculiar
some more information: nothing even shows up in device manager. no unknown devices, nothing. the phone charges, but thats it. i might go to the verizon store and see if i can get another cable
My guess is because you are using a 64 bit version of windows..

Why would that matter at all?
The 64bit version of Windows 7 is notorious for not being compatible with a lot of devices. There just arent any 64bit drivers. If you dont understand how to run your software in the proper compatibility mode you will run into problems. I used the x64 version of Win7 for about 12 seconds after I realized my ancient usb optical mouse didnt work lol.
My advice, try running the Samsung driver installer in compatibility mode and see if that doesnt help.

Compatibility mode won't do anything in the case of drivers. I'm not sure what your issue is though as all of my Samsung phones have been picked up fine from within Windows 7 x64. Is the phone picked up on any non-Windows 7 computer? Have you checked in Device Manager to see if it just needs installed?
its the cable. i took mine to the verizon store, they tested it, and gave me a new one for free. works perfectly now
Excellent, problem solved!
So it turns out a factory reset fixed it. Using a moto cable. So that's definitely not the issue. Flashing froyo now. Thanks!
I have encountered that a few times also. Its weird cuz when I plugged the usb into ac charger it almost immediately asks if I want to mount sd for data transfer. 20 mins later I unplug usb from unit and plugit into my win7 pc and nothin? So plugged back into ac unit and it recognize....so I mounted and it didn't know what to do lol. I then plugged back intopc...waited...changed orientation and 'Boom' pc sees it...in fact I change orientation whenever it seems to hang and seems to work....

I should also note that I have never used a samsung cable and every usb micro I've used (moto,kodak,BB,Lg) has fit and worked. But I have noticed some usb related quirks since froyo update like no lock screen after charging till I push home button, inaccurate batt icon (goes from 3/4 to 1/4 in like 10 mins but overall batt life is same as before)...
On an unrelated note I also can't get v6supercharger to work...?

It's the Cable.
I have issues getting my Epic recognized as well, but don't fret.
The stock cable will still work, you just have to give it more chances to recognize.
When you install drivers, they don't always go through on every usb port your laptop/desktop have. some ports will work better, like on-board powered ports.
I assume you know your computer better than anyone else and already know which usb ports never fail you and which ones are a little iffy.
Factors aside, wether you be on xp, vista, or windows seven, or even Windows 8 beta... LOL. Open up device manager.. if your 'unknown device' (your epic) is connected, leave it that way, and go down to the usb ports section of device manager. click down on the arrows and you'll find 'unknown device' that's your epic. Right click, uninstall.
now, do the following.
If you're trying to flash/odin.. make sure your SD card is out. as you want your phone to be recognized for a modem, not a usb massive storage, but if in fact what you're going for is the ability to browse through your phone's sd card with your phone connected, then obviously leave the sd card in.Disconnect the usb cable from your pc's end. Make sure your plug is completely inside your phone's micro-usb port. Now, either try the same port again, or choose a different one, do realize that your computer will have to 'recognize' your phone and install the drivers installed on your computer for each new port you try it on. You'll eventually realize which port works best and get full recognition, just give it a little time and patience and you won't be dissapointed. Old Windows XP takes a little longer for usb recognition than windows vista or snappy windows seven. Cheers and i hope i was of any help to you or anyone else browsing around. =]
My Nexus is stock but it is unlocked.
I have the latest CWM on there (touch 5.8.0.2)
I was currently downloading all the necessary stuff to flash to AOKP but havent even got there yet because all of the sudden my USB isn't working.
I have tried two different cables, the stock one and a different one (both which were working before).
I get charging working through USB but no file transfer.
I just did a wipe data/factory reset and wipe cache via Recovery, and still nada.
Am I cooked here? B-stock with no warranty from Expansys, now currently kicking myself for not buying brand new.
[edit] yes MTP and USB Debug were/are both checked on
[edit2] a lot of my searches seem to indicate that you can move and transfer via adb in recovery or fastboot while having this error. I am not finding that to be the case.
[edit3] windows 7 does not show any indication of a usb drive or anything plugged in as it used to before. This is obviously making it hard for me to try things like reinstalling drivers and whatnot.
thanks
It probably has nothing to do with the USB port...
Plug your phone into your computer, and then scroll the status bar down. You should see a notification "Connected as xx" Select that, then make sure connect as MTP is checked, if it's connected via ptp (camera) it won't allow you to sync files, for what reason so ever...
If that doesn't help, then reflash stock ROM, that usually helps.. With most problems anyway...
If both of these don't work, then I'm sorry, but I can't help you. I'd then call Samsung, and send it in...
LG Simon
Yea MTP was already checked on. USB debugging being on would have auto kicked in as well.
I flashed AOKP but still the same issues. The hardware might have gotten bonked - I hate how fragile these tiny little ports are!

Had this same issue yesterday ( phone was 1 day old ) had it plugged into my windows 7 machine and all of sudden the machine couldnt see it. So I wiggled the cable sure enough the computer saw it, jiggled it again and it would lose connection to the PC. Tried this on several PCs with Several cables and same result everytime. If I held the cable connected to the phone at the right angle it would never lose connection.
Ran to Verizon and the numbskull behind counter tried telling me that is normal and I would just have live with it, almost punched him in the throat. Demaded he go get another phone and show me if that one does it. It didnt so he swapped it and was to hasty about it, ended up giving me another cable charger and headphones WOOT WOOT
new phone doesnt do it as of this writing
See http://forum.xda-developers.com/showthread.php?t=1427539 This is probably the issue you guys are experiencing. Seems like you should swap it in or try to fix it yourself by changing the USB charging board.

i used a samsung usb charger last night which i usually never do (i usually just charge it on the computer) and now this morning i have no data connection.
Hello,
have this problem already on my GNEX. After some reading, i got an idea to turn off Fast Charge in Trickster MOD.

Just so y'all know...Fast Charge is simply tricking your phone into thinking it's plugged into an AC outlet...rather than a USB port.
Thus MTP won't work.
same issue here
I'm having the same issue here. Charging works fine with 2 computers and multiple USB cables (as well as AC and car charger adapters), but data transfer has completely stopped working. My computer won't see my phone at all. I have the correct drivers (given that I used them to connect to my computer when I first rooted and unlocked the bootloader). Tried changing the drivers, but I can't get my phone to show up in Device Manager at all. MTP and USB Debugging are enabled.
The only thing I can think of is that I dropped my phone while it was connected, and now the USB cable only charges the phone if I bend it in a certain way (it usually requires upward pressure where the cable plugs into the phone to work). However, other USB charging cables work just fine without any pressure. Is there any chance that a new OEM Samsung USB cable might solve my problem? The other cables I've used weren't OEM.
I normally use a wi-fi data transfer app because the USB data transfer has been slow since day one, so that can be worked around. What IS a major problem for me is that I'm trying to re-root my phone after my root access was lost with the 4.0.4 OTA update. I didn't keep up with the news and only realized last week that my root access had been lost because I tried to do things that required root. Since the OTA update trashed my CWM recovery image, I seem to have no way to re-root and reinstall CWM aside from going back to my computer and doing what I did the first time. But if I can't connect to my computer, I can't do that. It also seems that I would need computer access to remove root in case I bring it back to Verizon for a replacement under warranty.
So on another note, if you guys know of a way to re-root my phone without connecting it to my PC, I'm all ears...

I have run into a lot of USB defects on the phones I have received. It might be wise to get Samsung to repair it, but you will be without a phone for a week. You could also try another cable.
I used to have similar issues except where the power got routed into the data port, frying my phone in multiple areas.
On Samsung's repair ticket they said REPLACED COMPONENT (I'm assuming this is the usb controller and port) this could be the solution but it requires sending it in.
Hello,
I hope someone can help. I am trying to get my computer to recognise my phone. I am not rooted and I have Marshmellow 6.0.1
I unlocked developer options. I bought a cable and it worked! The computer saw my phone. However it stopped seeing my phone. Why I don't know! But when it did work I saw the driver was not for the 5x but from my S4. Well since it's not working I ordered the recommended USB cables by Benson Leung Tech Matte. Still unable to see my phone. Tried cables on another computer with same results. The computer I tried it on recognised my phone and then it also stopped seeing my phone.
I also bought a usb c stick to use on my phone. My phone responds to the stick but when I choose for MTP from charging nothing happens and i cannot access the USB Stick. In Dev options MTP is selected. I also noticed that USB tethering is not available. I have no clue what to try next.

USB debugging needs to be selected. Also, you need to toggle to PTP and back to MTP
Install correct drivers onto your pc

Thanks for the drivers. USB Debugging is on. When I toggled Charging popped up instead of PTP and so I kept toggling and it finally went to PTP and so I toggled MTP and it goes back to charging! So I kept at it until it finally went to MTP. Is this normal? I counted 12 tries before changing from charging to PTP! But the computer doesn't see the phone. I did it a few times

i honestly never thought about this, is this even supposed to work without some kind of an OTG adapter. i mean sure, the plugs fit, put do the pins match/work for that configuration?
from how you describe that your phone reacts i would guess it doesn't, and it sounds more like your phone goes into client, as opposed to host mode.
very interested to see what someone with more knowledge of the matter would have to say about plugging a usb-c memory stick directly into your phone.

I can read/write to a sandisk USB memory stick using the proper adapter and using USB OTG file manager for Nexus from the play store.

I've used several phones on my PC and at first it had a little trouble but finally settled in. Kind of like a new ROM. You have to give it a while to settle in and get its groove on.

not really a surprise there, but what OP described was putting a usb-C stick directly into the phone, without any cables or adapters in between, with the question emerging if that is even supposed to work (which in his case didn't) due to possible problems of the pin-layout, etc.

that does not explain his PC suddenly not recognizing his phone anymore though.
at this point it sounds to me like either there still is a driver issue (e.g. the mentioned S4 driver wan't properly uninstalled), or one of the usb ports (phone or pc) has an issue.
try different ports on your PC and make sure other devices work with the ports. if not try if you can get it to work by applying a little pressure in different directions to the cable and listen out for windows' annoying usb sound.
on the other end make sure your phone really is connected correctly to the cable. it should snap in just like the OEM charging cable which took some time getting used to to overcome the resistence of the usb-c port.

Thanks again for your quick reply,
I tried my Samsung Tab II tablet and my old S4 on my PC and they both work as advertised. Recognised right away and I hadn't used my tablet to my PC before. What I think is maybe its the USB on the phone itself?

I think its the phone itself, since it did work briefly. Also with the USB C thumb drive the phone recognises it but will not read the thumb drive. I ordered it from play store I wonder how getting it repaired/looked at is going work Have to wait until Monday to call!
Hello again,
I Hope you guys like some feedback about my issue. Contacted Google and they asked me just about all the same questions and had me do some screen shots and try some of their ideas such as factory reset, trying other computers and other cables. Nothing worked so they sent me a new phone! Just got it yesterday. Would have been here sooner but I was busy!
So got new phone setup and the computer recognizes my phone on PTP but not MTP. Also my driver for the phone is a generic nexus and the it still shows up as a samsung! How can I get the new driver if when i do a search for new driver my computer says I have the best driver already installed? I don't want the driver to still be a problem. So i hope you guys have some answers. Lol! I know you guys do!!

If you had a samsung phone before you need to uninstall all the samsung drivers then install the proper nexus drivers
I was a little worried about uninstalling the driver but it worked!! Thanks! Now i can root it!!
