USB not recognized - Epic 4G General

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

Not the usual PC connection issue

Hi!
Ive got a big problem cause my Galaxy S just stopped being recognized by any PC. I dont know whats wrong, it just treats USB cable like it was a charger, PC doesnt detect anything neither does the phone. Its very strange since everything worked perfect for the last couple of weeks. I tried to connect it to a notebook i used to flash the phone a week ago and it has been turned off ever since so it cant be any driver related issue. Im afraid my micro-USB port is damaged but i have a custom firmware in it and since i cant reflash it the warranty isnt vaild ehh...
Any ideas?
THX
silly question...
Do you mount the phone via the status bar after you plug it in?
Thats the point - PC doesnt detect the phone AT ALL theres not even a sound that an USB device has been plugged in. The same thing in the phone it just starts charing it doesnt seem to know that its connnected to PC.
sounds like your PC mobo got the USB port fried.
try turning off the PC, unplug the power cord, wait for the energy to drain out, then turning it back on
my Windows 7 x64 some time does that, but it's not a hardware error
on yours it could either be a hardware dead, or the Windows gone Bezerk as usual
I tried different USB devices - other phones, pendrives and a printer and everything works fine except for the Galaxy S. The Samsungs USB cable also works fine with other phones..
I wrote to Samsung and they said to send them the device because its most probably damaged :\ Will they check the firmware version?
btw. as I said in the first post the phone doesnt work on my notebook as well
I wouldnt care so much about this because I can send files using ftp but I cant change the firmware without an USB port working (or am I wrong?)
I sometimes also have this problem. For me rebooting the phone and if it then doesn't work again using another USB port at my PC solves the problem.
Yesterday when the problem occurred for the first time I removed SIM and microSD cards and PC detected a device but it was recognized as 'unknown malfunctioning USB device' but no luck ever since.
Just to let you know my Samsung just fixed itself 0_o Might have something to do with the Windows reinstallation on my PC but it suddely works on my notebook as well. Im really confused now...

[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.....

Did you end up doing an ODIN restore

Computer not detecting phone through USB at all!

Argh, I am pulling my hair out trying to solve this! When I connect my phone through USB to my computer my phone detects the connection but my computer doesn't respond at all! I bought the phone used and it is already rooted but is using a pretty old rom and I wanted to upgrade it. It is currently running "Kernel version: 2.6.32.9 [email protected] #4".
Things I have tried:
Using different USB settings on the phone (Kies, mass storage, ask on connection)
USB debugging mode
Different USB cables
Different computers
Cleaning the micro usb port on the phone
Formatting SD card
wide data/factory reset
Nothing seems to accomplish anything, it still reacts in the same way.
Any help would be greatly appreciated!
The ROM shouldn't count.
First of all, has it ever worked? I just presume you're running on win7: did you installed the drivers as specified in several different tutorials on this forum?
What kind of connection are you trying to establish? tether, usb, kies, other? have you tried any combination possible?
I just got the phone a couple days ago, I have not managed to get it to be detected by anything yet. I have tried it on a couple Win 7 boxes and also a Vista laptop. I am currently downloading Ubuntu just to rule out the OS factor. I have just been using Kies to install drivers although after reading your post I found this thread:
http://forum.xda-developers.com/showthread.php?t=961956
I'll try that and post results if that is what you mean? I have been trying to establish basically any connection at all for the ultimate goal of getting Odin to actually detect the phone so I can flash it with ClockworkMod Recovery and then an ICS rom. The phone detects the USB cable fine and starts charging and puts the phone into whatever mode I want (kies, mass storage, etc.) but the computer has yet to give any indication that anything is connected to it.
Try with the drivers, but be also sure to enable usb debugging to be able to select a different usb sharing when inserting the cable in case you haven't already.
The drivers installation didn't make any difference and I've tried USB debugging and all 3 connection modes (Kies, mass storage and media player), none of which exhibit any response from the PC.
Edit: Posting from Ubuntu now, same exact thing. Phone detects USB connection, and it doesn't matter which of the connection options I choose as the PC doesn't give any indication that anything has been connected to it.
That's really weird. Does Odin3 (which presumably works at a lower level) sees anything if you put the phone in download mode? ) this way you should be probably able to upgrade somehow.
Sent from my galaxys using XDA App
No unfortunately there is no response from the computer or Odin3 when the phone is in download mode and connected through USB.
that's odd and maybe that's not good at all.
I'm starting to think the problem could be hardware related, especially in a situation where odin can't see the phone in download mode (i.e. no software layer is interfering).
Is there any glaring damage/scratch/missing parts on the usb port?
Sincerely, if I could return it I would try that at this point.
Unless someone else has got anything else to try.
I'll take a good look at it under a scope when I go to work on Monday I guess. Thanks for your input, I'll try to update if I find out anything else!
So I took a look at the port under a scope today and discovered that one of the pins (the middle one) in the micro usb port on the phone seems to be completely gone! Not sure what each pin does but I'm assuming that one is probably used to communicate to whatever the phone is connected to...
Luckily I have access to a parts phone that I can take apart for a replacement port so probably tomorrow I will attempt surgery on the phone! Will report back with further progress after I have done so.
Well I'm happy to report that that was definitely the problem! I replaced the micro USB port on the phone today during my lunch break, put the phone back together and plugged it into a PC here. It immediately detected the phone so I'm pretty happy! Guess I'll be trying out some ICS roms tonight when I get home!
that's great, glad you managed you fix this yourself, well done and enjoy your SGS

Cant connect samsung S1 to PC

Hi,
I'm having a real though time trying to connect my galaxy s1 to a pc. Have tried everything, like kies, direct connection, reseted the device, and no joy.
When I plug the cable it makes that sound as it is connecting but it doesn't show in the PC anywhere, nor even in Device manager.
It can get pwr from the usb cable when is connected; already tried with another cable and same thing.
My final goal is to unlock it.
thanks for any help
have you tried put yoy're phone in depurating mode?
I guess yo mean Debugging mode, as I couldn't found Depurating anywhere. Have selected it and the same effect
HI
I had the same problem after getting nowhere with it, for some reason and I don"t know why, I put it in download mode and then connected it to odin and my PC found it I then disconected it and its been fine eversince.

#Samsung Kies always makes problems on Windows x64 !
##I would recommend, if you got 32-Bit Computer, to use that ;-)
#If you Want just flash over Odin, then is this driver package enough

#The Package is also enough for If you want just to connect to mass Storage (Phone's SD Card)
Don't Forget to Thanks, if it was useful for you!
_______________________________________________
Hi there.
By direct connection you mean the USB Mass Storage mode, right?
It might be some weird, random problem with the samsung system drivers. I used to have such problems about two years ago, back in the days of Froyo. Have you tried re-installing them? There was a link to proper drivers file in one ICS installation tutorial, and those drivers can be downloaded here. If you go about trying this method, lemme know if it worked.
Cheers.
PS: Unlike diklooc there suggested, do not never EVER go back to x86 OS. That's the worst advice. Kapisch?
Did you check your usb port in System ?
Sometimes it stuck with another lastest device
Hi,
have tried everything, and finally only in a WinXP32 could be abble to get the error shown on the file atached.
But nothing (warnings) come up in Device Manager
Unninstalled everything (kies) and tried to install only the driver and nothing happens.
Should I try to mount it on a linux?
or is it dead?
thanks
i have this problem too
wat chan I do???
my sgs can not connect to my PC
This may help...
Hi there - I don't have the same phone as you, but I did encounter the exact same problem. I've been searching around and it looks like the most common fix was to simply replace the cable. I don't know what kind of cable you have, but my phone (a Samsung Focus i917) uses a mini-usb connector. I found that my Amazon Kindle used the same connector.
When I was using the Samsung cable, I'd get intermittent connects and charge power. The OS would report unknown device. When I switched computer's = same result. I switched to my Kindle cable and the computer instantly recognized the device and installed the drivers. After 12 hours of troubleshooting, factory resetting my phone (blah - lost everything) it turned out to be the cable. I know that this isn't an easy troubleshooting step for most people, because who has an extra cable? I just got lucky that my Kindle uses the same connector. I'm now suspecting (due to the prevalence of this connectivity problem coming from people with Samsung phones - there are a LOT of reported issues) that there is probably a Samsung cable problem in general.
Good luck with your phone.

Nasdriver, I currently have a similar problem but mine is related with Samsung Kies as I can't get either my older SGS1 or my newer Samsung Nexus to get recognized by Kies. I also suspected the cable thing and even read it could be a USB port issue but neither of them was my problem (I have 3 cables and 8 ports on 2 computers that result in the same thing). I can connect other devices with the same cables and they work, so I suspect my problem is focused around the Samsung device drivers.
My advice is if you can go in a systematic manner, first focus on the cable (easiest to replace), if you get the same results with a new cable, then focus on the USB physical port, clean it with some Isopropyl alcohol, if the port works for other devices (camera, other phones, etc..) on the same cable but not with the SGS, then try reinstalling the samsung device drivers.
Oh, and if you want to unlock your phone, the EASY way is to download the Galaxy S Unlock application from the Android market (no affiliation) it's free (but the developer does accept donations) and it WORKS. I won't bore you with my 3 week journey trying to unlock my Bell SGS phone here in Canada, had I found this app first I would have done it in less then 2 min saved myself a LOT of frustration.
Good luck

[Q] USB Connection

First off I have searched repeatedly and cannot find someone with the same problem as me. So if there is point me in the right direction.
My Nexus 4 won't connect to a computer via USB, it will charge, but it treats it as if it were plugged into a AC adapter. my computer also does not recognize that there is something connected to it (no errors, no trying to install drivers, and no unknown devices in computer management).
I have tried:
Multiple USB cords
Multiple Computers
Multiple OS's
Multiple ROMs (it has an unlocked bootloader from when it worked)
Does anyone have any idea what's wrong with it? Or how it could possibly be fixed?
Thanks,
Matt

Sorry for late reply, I've been busy.
Yes, ive tried that too, no difference. It's not seen by adb either...

i had the exact same issue and was able to get it fixed by using a usb 2 into 1 cable. like the ones that come with an external portable cd writer. once it got recognized, i wiped completely and went back to stock and locked bootloader. problem has not come back since. it was probably a bad flash that caused the issue.
once you get it going again, get it rma exchanged just in case.

Still no luck with the cable, it does not recognize that it is plugged into a computer and the computer doesn't see anything plugged in
i had same problem but my problem was on windows xp. when i try windows 8 it receognise it and than i install driver on my xp pc.
on your problem it can be because of the micro usb jack of the phone. if it gets charged it should get connected also.
I am having the same problem. My Nexus 4 used to connect to computers just fine, but now it only charges from them. Like the OP I have tried many things:
Multiple USB cables
Multiple Ports on...
Multiple PCs running...
Windows 8 and 7
Debugging On or Off
MTP or PTP
Multiple versions of CyanogenMod
Factory Data Reset
Absolutely nothing lets my N4 connect to a computer (besides charge)
When I go to Settings>More...>Tethering, the USB Tethering option is grayed out and it says "USB not connected)
If anyone has the solution, please help.
