[Q] USB Mode - Epic 4G General

Did anyone ever find a fix to the usb problem some epics have? Every time I plug my phone into any type of computer, it will work for the first time I plug in, but if I unplug it and plug it back in, my computer says usb device not recognized. This also happens in my BMW, it let me listen to music through the usb once, and that was it, now it doesn't even read it. I've heard of others with this problem, but I haven't seen anyone fix it. I don't have Sprint's insurance, so I don't know how things go towards getting a replacement. I also tried downloading an app to automatically mount when usb is connected, but no dice. I have tried different microsd cards too but same problem.

i only have this issue on damn dell computers it seems, i dont think there is a fix, however what i do to get it to recognize is just unplus both the connector to the phone and the usb from the computer, and then it registers finally.. Its very annoying but it will work, just try that, i hate that but only have issues on dell, my 2 HP's work great with connectng

Changing the micro usb cable also helps. The one that came with the phone is garbage. I personally use the cable from my evo

PC doesn't sync with Vibrant... help needed

I hook up my Vibrant to my PC and nothing happens. The phone starts charging but I never get a prompt on my computer or sound notification that something has been mounted.
I go to my computer and see nothing of an external hardware source being plugged in.
I want to root my phone but I can't seem to get my Vibrant to show up on my computer. My MyTouch Slide had no problem. Suggestions?
I've already tried changing the USB drive settings...
I am not near my computer right now, so maybe someone more experienced can give you precise advice, but what I did for my PC (XP Pro) is download the Samsung USB Driver, install it, and only then the PC would recognize the phone.
Also, after your phone is recognized, you still have to mount it as an external drive from the phone itself before it can work.
See this is why I hate windows. I spent the last half hour trying to figure out what was wrong with this. In the end, simply plugging the USB into a different port fixed everything.
Have the same issue here. One port works and one does not recognize the Vibrant no matter what I try.

That's not a windows problem, you have an iffy USB port
Also, now that you have fixed your issue, why not just download the update.zip file directly to your phone, no need to use your pc.

USB issue

All of a sudden my pc is not recognizing phone as a usb drive.. It was working perfectly since day one with this phone but since yesterday it wont recognize it.. And even if it does, it takes a very long time. ive treid uninstalling the drivers and reinstalling, as well as turning debugging on and off. My pc is running windows 7 64bit.. I have also tried different roms and nothing.. When connected in debugging mode, it recognizes it immediately and installs drivers by i still cannot view my storage card.. Any help would be appreciatied.. Thanks
Install pdanet on your computer. When it gets to the part about driver installation, select samsung and voila.

Seconded. I bought a cheap charging kit and the cable would charge but would not allow file transfer. Took it back, bought another cable and it's fine.
Either the phone is finicky about cables, or it might just require a particular type (probably USB 2.0).
I had this issue also last week. I tried another cable and it worked fine.
But now I am having issues with my usb ports in general. Now they just stop working every once in a while and I am required to restart my laptop.
Don't know if the two problems are related.
Try different USB ports. Like the ones on the back on your computer.
I've been having the same issue. I went out to Radio Shack and bought a new data cable. So far all ports on my laptop, winXP pro 32bit, and my win7 64bit desktop have not had problems.
I'm thinking that the USB cable supplied by Samsung is crap. I tested them both out on the same machine, same port; the new one worked fine, while the stock cable only gave me adb access.
I had this same exact problem. I kept thinking the phone was going bad or something. I tried the cable that came with my Epic & the one that came with my Moment, both didn't work... for some reason it worked find on a Mac though. So when I gave my mom my Moment when I got the Epic she bought an extra micro-USB cable and I decided to try that one, for some odd reason, that one worked.
Still don't know exactly what was going on but a third-party cable fixed the problem for me.
Hope this helps.

Phone is not recognized when in download mode - please help!

After failing again and again and again, reinstalling the drivers, reinstalling KIES (which simply won't work on my machine), removing the battery etc. etc. etc. I just don't know what there is left to do...
When in Win7, the phone is recognized, although Windows tells me that it's not connected to a USB2 hub. In download mode it says connection failed. What else am I supposed to do?
The phone is not branded or anything, applying stuff though update.zip's was never an issue.
So please somebody help me - I'm stuck with JF3
simple, switch to another computer
unless you can find and easy way to make windows forget the USB bugs
you need to also unplug the PC and wait for the PC to power drain, reconnect the PC power cord, and turn the PC back on.
after it goes back to windows try hooking up the phone again, if you get the message about not running in USB2 mode, then it failed
retry after resetting BIOS settings, installing USB2 drivers, etc.

I had a similar problem...
I had a USB 1.1 Port on my Thinkpad T22 and the drivers didnt like it
Use a different computer/USB port
...btw I still like JF3
Now you will probably feel the urge to smack my head against the wall when you read what I'm about to tell you... I don't blame ya... The cause of the "problem" was that I wasn't using the original Samsung USB cable that came with the phone. I just couldn't find it so I decided to use an aftermarket cable which I had lying around. Big mistake... I finally found the USB cord and that fixed everything for me. Beware of aftermarket accessories as the phone will punish you for using them!
that cable might have been a very poor after market version then
i do use a couple of after market USB to micro USB cable with the phone and it works fine
there are bad aftermarket products
and there are quality aftermarket products
I remember having a few mini USB cable with my old G1, and had similar problem. With one cable it was recognising, with the other one didnt.
Don't know what difference they have, but it's indeed wierd!
I was using a nokia usb cable to flash my samsung

USB not recognized

When I plug my phone into my usb port I keep getting an error message
That says
USB device not recognized
one of the usb devices attached to this computer has malfunctioned and windows does not recognize it. For assistance in solving this problem, click this message.
So when I do that it says unknown. I know I have the drivers installed because I can odin back to stock. I am thinking this is the reason why wired tether will not work.
Can anyone let me know what the problem may be?
Thanks.
This has happened to me from time to time. A reboot of the pc and phone has always fixed it.
I just realized I have never used this cable with the phone. I got it at walmart and it is made by fuse. So it could be the cable.
Also try a different usb port. Mine got error error messages on some ports but not the other on the same computer.
I bought several usb cables for cheap online. 1 totally stopped working, and another one disconnects the phone is I move the cable.
I always suspect the cable!
I am having the same problem with my laptop atm...
My computer can't seem to see the epic when it's in d/l mode. I've installed the samsung drivers as well...but no go.
Hopefully someone has a suggestion to fix the problem. I'll be seaching the forums in the meantime.
had the same problem try a different usb port aslo dont use usb multi hubs.
I have the same problems as well.
A reboot fixes nothing.
None of my ports work.
I do not want to replace my epic but this simple issue is nerve wrecking.
I have a similar problem. Both my wife and I have the epic. I have no issues connecting my phone to either of our computers but when I connect my wife's epic neither of the computer's see the phone at all (not even as an unrecognized device). The phone asks if I want to mount the sd card and I say yes and nothing happens. I've tried usb debugging and I can't get Odin to work either for hers (fine for mine). Has anyone else had this issue?
Thanks

[Q] Epic not mounting

I cannot get my epic to mount for ANYTHING! I factory wiped the phone, nope, I used a palm pre usb cable nope, I downloaded the official samsung drivers nope, I plugged the cable into the motherboard on the computer nope, I tried a different computer running windows 7, nope tried a laptop using windows vista, nope. Does anyone know ANY WAY POSSIBLE to get this thing to mount? I selected mass storage and dissabled and enabled usb debugging. Im just not having any luck. It seems that the computer recognizes the phone is connected just cant get to the files on the SD card.
I also spent many hours trying to figure out what the hell was wrong with my Epic, that is, why it would come up as a "malfunction" in Windows when I plugged the USB cable in.
I tried drivers, different restore points, wiping, etc. etc. etc.
To the point... Try a new USB cable. The one packaged with the Epic is junk. As a matter of fact, it worked several times before it crapped out. I have no idea why, but I picked up a new micro USB cable, plugged it in, and the phone was then immediately recognized by my computer to allow mass storage mount.
People who tried the Palm Pre USB cable also had issues for some reason.
IMO, there should be a sticky posted in this board regarding the packaged USB cable, as I encounter this issue quite a bit.
Ok I'll try to find a new one really quick thanks
ugh tried an HTC Mytouch 4g usb cable and that didnt work either. Gonna try a class 4 usb stick and im gonna try puttting all of the files on the computer from the SD card
Edit: Oh wow i cant put the files on the computer duh
Edit: Ok now I'm mad a Class 4 SD card wont connect to the computer thru the epic ughhhh
I'm guessing during this time, you've rebooted the computer a few times? Sometimes, that's all it takes...
Try uninstalling ALL of the USB drivers associated with the Epic, rebooting the computer, then connecting (with debug mode OFF). Windows found and installed the USB drivers for me in just a few seconds when I did this [with the new cable, the first time].
- G
Have u enabled development mode under settings > applications (in your) epic? If not, try that, then plug in cable.
Then pull down the notification bar and it'll give you back the option.. again, if you haven't tried this.
On occasion I have troubles with the Epic mounting/ejecting on a Mac, but the only time I've ever had an issue with it mounting on a PC a different cable solved the problem immediately.
Try a different USB port on your PC. If that doesn't work, try rebooting the PC and the phone.
I had luck with trying different usb ports though
I had this problem as well and:
1. Tried 4 different cables
2. Tried all 4 on all 4 different USB ports
3. Rebooted numerous times
4. Uninstalled/reinstalled drivers
5. Tried 3 different PCs (1 other running 7 and another running Vista)
6. Did 1-4 on all three computers.
OH! and the reason I was so adamant about finding a solution was that I was stuck in Clockwork... due to having messed up an EXT4/RFS/CW2.5/CW3.0 installation... It was MY fault... I screwed up.
The problem was I had been living with the nonmounting problem by simply putting my MicroSD into an adapter and plugging it into my Laptop for file transfers... never expecting to HAVE to ODIN at some time...
Anyway... I ended up coughing up the $100 to Insurance and replacing the phone.
HERE IS MY THEORY: I think what my problem was was that the USB port on the Phone was messed up. I think these USB ports are possibly a hardware fail point and the changing of cables has been a patch on the issue with the port... NOT the cables themselves!
I'm not suggesting that you are there yet since it sounds like you can at least still get the phone to boot up (and aren't stuck in CW) and could still use a work around of putting files on the MicroSD with an adapter...
But I would suggest you don't be as stupid as me and get yourself in a position where ODIN is your only hope.
Yeah, it sounded like a bad USB port to me. Also, FYIY, if you ever have to replace the phone through insurance, tell them that the phone was lost. Either way, it will cost you $100.00 to get a replacement and when it's reported as lost, they will also send you a new battery...

You don't really think that I sent in a phone that was stuck in CW do you? I don't think that would have worked too well for me.....
Cheers!
Did you end up doing an ODIN restore
