Computer not recognizing epic

Anyone else this problem? Rooted my epic with the all-in-one method a week ago, worked flawlessly. Today when I plugged my phone to my laptop (the same one used to perform the root) it did not ask the 3 options (charge, mass storage, or tether). Turned on debugging again, and no orange triangle on my notification bar. I have connected to my computer several times sinced the root and it all worked until this time. Seems as if lost my drivers somehow but I never did anything to do that. Any suggestions?

Try rebooting the phone while plugged in. I have to do that in my Mac, and I'm running a custom rom, but it doesn't hurt to try it.

Try a different usb cable. The stock cable is **** and my pc would never see my phone using it. This is a common problem. Monoprice has them super cheap if you don't have an extra to try.
Even if the stock cable worked once it can be flacky. The other thing is make sure you use the usb ports on the back of the pc.

No usb available, other options?

I have a very strange issue going on with my fascinate right now. Before I go into too much description, here is my setup, to see the big picture. Rooted, stock vzw with geekniks stupidfast for DI01 (thought original kernel was original issue). I've tried to force the ota to DL09 and I get "IP_PREVIOUS_UPDATE_FAILED" as it fails to verify the dl signature.
Ok, on to my true issue. When I plug my SF into my pc, I get unrecognized usb device. I have the drivers installed properly and have previously been able to use odin via usb. My pc doesn't see the sd card mounted or anything. I'm debating unistalling the usb hub and restarting the pc so it will pick it back up as a new device. I have debug mode and unsigned checked, however, the little red triangle is no longer present like it used to be. I also every once in a while have issues with my battery level being accurate, as in it shows 100% when its really at 36% etc. It still charges, and recognizes being plugged in (haptic and audible confirmation).
Anyone have a clue or suggestion? I'm new to android, but well versed in the pc world. I just installed the android sdk in hopes of maybe doing a wireless adb push eventually. I'm A) trying to correct the issue and update my os/rom, or B) somehow get me back to stock and unrooted without being able to usb odin, so I can swap out for a new phone.
Thanks in advance for any help, whether it works or not.

Oh yeah, I'm running Win7 64bit.

so you are on stock vzw but you have used odin before. Did you use it to get clockworkmod on the phone?
did you return to stock from dj05 or dl09 OR have you always been on stock rom

I used odin to flash cwm. I'm on DI01 upadate-1. Had done the first update ota, then rooted and flashed cwm. I have been running that since until today. Thought kernel may have been issue, so flashed geekniks kernel for DI01 and have seen no change, except better performance as was expected. That is where I am now. Thinking about going back to previous kernel, but this seems better until I decide what I can do. Original nandroid and other in betweens to date still manifest the issues, which are only recent, like last few weeks.
Thanks again.

Does not see the Samsung SD Card
I have had similiar issues since DL09.
Try turning off your phone then reconnect USB after it reboots.
Seems to want to see it as a CD Rom.

I've rebooted my phone and pc, multiple times, no luck. Oh, one other thing, I tried popping the sd card into a card reader and I was able to see the files briefly, and upon trying to select anything, it totally disappears from view, as in pc doesn't see card anymore. Now I can't get the pc to see it at all. So I can't read/write it that way. My phone still sees it and can mount and unmount for removal on phone itself, but not with the pc.

Try flashing a different kernel. My first fascinate was picky with which kernels wanted to work right with the.usb connection.
Sent from my SCH-I500 using XDA App

In my experience, you can still use ADB to push and pull things from your device even when your pc doesn't recognize your device. I know this doesn't help with flashing DL09, but it could help you push a different kernel to your device (or you could download one from xda forums via the xda app). A different kernel might clear up the issue for you. Good luck!

This fixes it....

For your first issue it is because you are rooted you will not get ota updates. You should use odin and flash DJ05 imo it is much better and there are more ROMs and kernels

Thanks for all the help, I'm going to give it a whirl later and see if it works. I'll let you know.

Before I get too far deep in, could I just unroot via a terminalapp and then force the OTA to get me up to speed? Would at least like to see if I can deal with the minor malfunction while still being current.

This won't fix the problem because he is not on DL09. It will likely make his problem worse. You might want to read the entire post b4 you give suggestion.
To answer your question sir: if you can't get your pc to read your sd card with a card reader, the problem most likely has nothing to do with your phone. It probably is a corrupted|damaged card. It could also be a problem with your computer (this can be ruled out by successfully connecting another usb device to your computer).
Most likely, you will have to buy another micro usb card.

Ok, been trying a few things, and I'm starting to lean towards the sd card being corrupt (as one of the issues), sending my important pics and backups of my contacts, sms, etc to dropbox as we speak. I actually tried the SV kernel from adryn, and my phone has seen no ill effects (possibly no haptic, but didn't care at this point), everything seems to be working just like nothing changed. I actually briefly got the USB debug icon up for a second and it said usb connected, however I was not connected to anything, lol. It had done this on the stock kernel as well. I've booted my phone without the sd card in and it starts up normally, but the USB debug icon is still not present, even though the option is ticked on.
I can still force my phone into download mode, however my computer still doesn't recognize the COM port, so odin is out of the question right now. If I were to get my hands on the stock kernel again, could I factory reset the phone, remove root, and potentially force the OTA and then reroot? I've seen some options for terminal apps where I could ru superuser and busybox. Any thoughts on that route? I may give my roomie's pc a try, when he's out, as well to widen my test field.

Well, I got my pc reading the card via a card reader, but not while inserted in my phone. I'm going to try to uninstall the usb hub on my computer and restart my pc with no usb periphs connected. I read somewhere that someone was able to get the phone recognized again, but I have a feeling that it isn't going to work, since I never see the USB debug icon anymore.
On a side note, I get a com.android.settings force close message somewhat frequently, on stock, geeknik and adryn's kernel. I've started unloading apps left and right, but no avail. Thinking I need to get back to full stock somehow without odin. Suggestions?

I had similar issues. No usb, battery flashing to 100%. Tried everything as you have. Couldn't figure out how to get back to stock without odin. I'm running DJ05 superdark with geeknik 1.54 kernel.
This went on for a week and I was ready to give up and go buy another phone when one day the usb icon flashed momentarily when I plugged it in to charge.
In the end, it turned out to be a dirty usb connector on the phone. Cleaned it with a paper swab dampened with alcohol. I still have no idea why it was so sensitive to the small amount of dirt that came off it.
Hope this helps.

Well, I tried the alcohol swabbing, and it mildly worked. I get the usb debugging icon more often, but it also shows that the usb is connected, even though it isn't. My pc briefly recognized it once. Would I be able to disassemble it and clean or replace the usb port myself?
I've even blasted it with compressed air.
Sent from my SCH-I500 using Tapatalk

You've gone farther than I had to. I didn't need to resort to compressed air.
Do you have more than one usb cable available? I had bought an aftermarket one in addition to the one that came with the phone.
The original cable is still wonky on connection. It charges ok (no more battery jumping to 100%), but usb recognition is a fifty-fifty proposition. The aftermarket cable does charging and usb correctly.
I have had to reset my PC's usb drivers once by rebooting the phone while connected (the PC recognized it as a CD-ROM drive). This may be coincidental or an indication of a chronic connection problem.
I speculate in my case that the aftermarket cable distorted the phone connector somehow so that it doesn't like the original cable any more. Pure speculation.
Anyhow, glad to see that you're making progress. I know how frustrating it was for me. Keep us posted.

I had the same problem at one point. I found out that if your turn the phone off, plug in the usb cord from the computer, then turn the phone on while the phone is still plugged in. once the phone reboots, unplug the phone, then replug the phone in to the computer and then the computer should recognize it. This works for me every time that i have this problem

Nexus 4 USB-Debugging doesn't work

Hi Guys,
I used the new Nexus 4 Toolkit to unlock the bootloader.
As I unfortunately dont have 10 Posts, I cant ask in this thread, so I hope it's ok to ask here.
I installed the drivers with USB-Debugging (as before for my galaxy nexus) and unlocked the bootloader.
So far everything went normal and good!
Then I wanted to root the system. It was said that I've to enable USB-Debugging again and the system will reboot.
But then :
I tap on "Enable USB-Debugging" and I'm asked If im sure. After this, nothing happens. Usually I see a information-icon, that usb-debugging is enabled in the taskbar.
This icon is now missing. And im completly not able to connect to phone via PC and use ADB.
Im slightly desperated, as anything I could do requires ADB/USB-Debugging.
Can you guys help me?
Thanks in advance.

Does your phone show up as MTP storage OK?
I remember my One X decided to cease all USB activity except charging once, a reboot sorted it.
The USB debugging icon is a little jelly bean as per the attached screenshot.

thanks for your reply.
I dont remember If it was shown as MPT-Storage - will check this immediately after work
THe Jelly-Bean-Icon showed up before, when used the toolkit to unlock the bootloader.
I also rebooted the phone several times

Ok, now everything seems to be identified correctly, again. Very strange.
Maybe the PC needed to be restarted.
Sorry for this post. It can be closed.
Thank you!

Were you able to resolve the problem?
I actually have the same problem also my Nexus 4 is getting very hot and the battery is drain within 4 hours from 100% to ~10% (about 400-800mA consumption).
All stock - I've already contacted the google support but now are holidays.

I've got the same problem, except my device is not loading until 100%. It gets really hot while not doing anything and it's empty in about 3 hours.

I figured out that the Nexus is only charged via "USB" although it's plugged in the charger.

Now my device is charging up until 100% but it still gets hot, is empty in about 5 hours and if I connect it in fastboot mode my laptop says that the drivers are not installed properly even though I installed the naked drivers. Re-installing the drivers does not work either, it says that my laptop already had the right drivers installed. And when I connect my device when it's booted it is not recognized at all and does not show up in the device manager. I tried three other cables... Sounds like an USB brick, right?

My battery life got a lot better with the new Franco kernel but the USB-debugging is just gone. I was wondering if maybe one of the recovery developers could help here. The USB brick solution for the HTC Desire was via Cyanogenmod. But I don't think that they know the solution since it isn't a very common problem as it seems...

[Q] N4 USB stopped working yesterday

I have always been able to find an answer to the problems I've encountered, but this one has me stumped. I have owned and rooted and tinkered and broken and fixed every nexus phone, all because of the help I can find here. So first off, thanks for all the years.
My new problem. Yesterday morning I plugged in my Nexus 4 like I always do, and tinkered with my music folder (added and removed a few tracks, like always) and then drove to work happily listening to my music. When I got home late last night, I popped onto AP and read about a new play store apk, 4.1.10 and installed it (just like I always do when I can grab it sooner than OTA). That is the ONLY change to my phone from yesterday to today. When I plug my phone in to my computer today, I get the "windows doesn't recognize this device" message. So, I do the usual, I fire up the SDK Manager, update all the required bits of the SDK, pop into a device manager, find the unrecognized device, update driver and point it the google/usb_driver folder because that's what has always worked when running into this quirk. So today, nothing happens. Phone still isn't seen by Windows. I have the luxury of 3 computers (one of which is Ubuntu) and a laptop to test on, and all 4 say the same thing today. All 4 have also always worked without issue. I have a Nexus 7 as well, and it has no problems across the 4 computers, but I have not updated the Play Store on the N7 (and now I'm concerned if I do this will happen).
So I start searching to see what others are saying, and I've found that many people have *just* run into this problem (across various forums etc.). I also notice that on my N4, even though USB debugging is enabled, it's not working (as in the jelly bean icon in the notification bar doesn't even show up now). And switching between MTP and PTP makes no difference either. I've uninstalled the unrecognized device and hoped windows would find it on it's own again, but nothing. I cannot access the phone via ADB (or communicate via fastboot) and literally have no way to see the phone. I wouldn't call myself an expert by any means, but I have always been able to get through manual rooting, custom ROMS, flashing radios and bootloaders on every phone in the past. What am I missing here? Is it possible that the latest play store update has somehow "broken" the USB function? I use bigxie's JDQ39 odexed ROM, and so do many of my friends (I'm the guy they come to), and not had an issue until today. Does anybody out there have any idea why this happening? And to so many people within the past few days? Also, when I try to revert to the 4.1.6 version of the Play Store, it will not allow me to install a previous version. Since that's the only thing I can attribute this change to, who can tell me how to do that?
I appreciate anyone who digs into this, and if there's any info I can provide to help you help me, just let me know!
Edit: Used TB to uninstall the play store and reinstall 4.1.6, unfortunately no change.

I`m pretty sure it`s your cable....It happened to me the 2 months after purchase! Probably if you plug it in a wall ac charger it will say USB charging instead of AC! That`s what happened to me. I`m using my good old G2X usb cable and no more problems like this

Ok ok, I tried it, no luck. I'm starting to wonder if a windows update could have done this. It just makes no sense that other phones/tablets work with the same driver and this was working fine yesterday. Windows definitely sees the phone, but regardless of what signed or unsigned ADB/composite driver I try, it still has a yellow exclamation mark. But when I plug in the N7, no problem at all. There are many ways to get data to my device, so at the end of the day it isn't the end of the world, but it still frustrates me. I just purchased a second N4, still sealed in the box as a gift for the wife, so my only concern now is being able to unlock the bootloader on that phone so I can throw a rooted ROM on it. If I can't see that device, then I have issue. But I suppose since it'll be new out of the box, should that happen, I can turn to the Goog for support on that one. I'm just positive that there's somebody here smart enough to figure out why this has happened I've seen more complicated issues resolved.

I would have tried to flash another kernel if I were you to see if the problem persists

When I connect my N4 to my PC, it shows up in device manager as as a portable device and mtp works fine. Checking the driver version shows that it is using WMP drivers. When I turn on usb debugging, that connection gets added as other devices in device manager with a yellow exclamation point. My device is detected since it will pull the serial number in a command prompt. I haven't tried anything thru adb yet, but for accessing your folders on storage, that would be the mtp as portable device connection anyways. The key thing is making sure that you are getting that connection and using the WMP drivers, not the Android usb drivers.

My situation is exactly like yours, for two PCs that used to recognize my N4. I tried another N4 that is stock and not rooted, and to my frustration it connected perfectly (MTP, adb, Fast boot). Something has corrupted our phones. Another symptom I have is I can only charge at USB rate with ac chargers that used to charge at ac rate. All this occurred around the 15th of May, when Google pushed the play store update. I haven't tried unrooting yet. I'm hesitant to get to bold on experimentation because I can't flash the phone with the PC anymore.

I knew I wasn't crazy! I understand your apprehension for experimentation, I sorta feel the same way. However, I've put some ROMs in some online storage and already put them on my device so I'm going to take the leap and hope I don't do any permanent damage. I've already overwritten my existing ROM more than once to see if it would correct it. So I have a different devs stock rooted ROM to try and a copy of CM 10.1 R3, I'll run those today and see if the suggestion of changing the kernel has any impact. I know there's a solution to this!

Ive tried multiple roms and kernels and nothing has helped. I just unrooted and no change. I think the usb firmware is corrupted, but don't know how to diagnose this. I even tried flashing different modems through the recovery (.27, .54, back to .48) and no change. I give up for now

Ok, so here's my progress, and ultimately my conclusion. I just wiped and tried another stock rooted rom by teshxx, it wouldn't even boot. So, CM was my last hope. Again, wiped and installed CM 10.1 RC3 , flashed gapps, and it booted up. There was still some issue with some of the google services, but fixed easily enough by uninstalling them and reinstalling them from the play store. When I plug it into a computer, I *still* have the "usb device not recognized" error in windows. And usb debugging still doesn't activate even though it definitely sees usb as the connection by looking at the battery settings. I realize that charging through usb is a different voltage etc. and why it knows has no relation to usb debugging reacting to the usb cable. That being said, I have to conclude that by some freak of nature, the data path through the usb port on the phone has stopped working. Perhaps a power spike? Maybe there is a god and he hates me? I don't know, but seeing as CM would have rewritten the kernel as well, this is about as far as I'm willing to go to try to diagnose this. Now since I can't use a computer to re-lock the bootloader, I'm stuck with a busted usb port. The phone is clearly within a warranty time frame, with the exception that I unlocked the bootloader and voided that upon purchase. I guess my advice to anyone reading this, wait one year and one day before you bother, so should a hardware failure like this happen to you, you can have it replaced.
Out.

PC USB Connection issue

Hi everyone
Recently I've been having problems with the USB connection.
I was on the stock rooted ROM, and I plugged in the phone and it came up with a message USB device not recognised because it malfunctioned. Tried different ports, cables and different computers, same thing.
Then I changed this morning to the Nexus 5 experience ROM. It worked initially. Now the problem has come back. However occasionally it does work and the windows explorer window pops up, but then after a second or two it goes away and the error message reappears.
What could be causing this?
It was fine a while ago.
Also, when it doesnt work, the battery settings thinks its charging on AC and not USB.

Sounds like it's a hardware issue

Hmm, its likely but could a hardware issue suddenly present itself with no apparent cause?

Absolutely, it worked for a little while and then didn't. Try flashing the factory image and see if it's still there. I don't think it's a software issue

OK I will try that.
The only new thing I've been using with it is a new car charger. It works perfectly fine, but if it was giving slightly too much or too little voltage could it have caused this?

I doubt it. There's built in circuitry that would take care of voltage or current fluctuations

Just a quick update. I smashed the screen a few weeks ago so I had to replace it. When I finished replacing the screen this also started working lol dunno what happened there.
