Weird problem - when I plug my phone into my PC via the USB cable, it charges (i can see the red light and the plug in icon) but the PC via WMDC doesnt see it. Nor can I see it when I view Computer. I have since did a factory HD2 reset and also uninstalled WMDC (twice) and reinstalled. Anyone know what the prob here is or how to fix? Thanks.
Have you flashed any ROMs recently? I had this problem when I flashed a new ROM. My front USB ports were very slow, I don't even think they're 2.0 half the time as Windows tells me to plug stuff in faster ports but, to solve your problem I think you need to change how your phone acts when connected via USB to PC.
Go to Settings, Other and USB to PC and make sure its set to ActiveSync.

That's not a solution it's a workaround and a crap one at that because all it is doing is disabling the usb rndis driver in favour of the much older and slower usb serial driver

I had this problem with my leo all last week. Then i went to my brothers place for thursday through saturday and had the same problem on his pc which runs windows xp pro sp3 (mine is windows 7 pro).
Turns out it was the phone itself. There seemed to be a problem with the tcpip stack, the rndis driver or the tcpip cache. Not sure which but a hard reset solved it and now everything is fine. Although thinking about it i only got the problem after enabling the tcpip cache tweak in bsbtweaks 1.6....... curious!
Don't plug your phone to the front usb, instead plug it to the usb ports on the back of your computer which directly goes to the m/b.
Flashing new ROMS has nothing to do with this phenomenon.
Bad USB cable or bad usb port could sometimes cause this, too.
I have not flashed the ROM at all w this phone. I did do 2 hard Leo resets but still have the problem. Running Win 7 Pro, checked the USB settings on the phone and its all good. USB plugged into the back of the PC and have tried multiple ports. Dang. Any ideas?
I had the same problem, I tried to connect it to several other PCs with no success, at the end hard reset solved it...
if a hard rest doesn;t fix it then task 29 the phone and reinstall the rom

Trust me, the prob is not with your phone, something to do with your PC. Any firewall program running, maybe?

Sorry mate but your wrong. The PC is fine. It is actually the phone that is at fault.
My experiences last week prove this and with no modification to my PC but only a hard rest on the phone everything is now working fine. The same with my brothers machine. No modifications made to it just my phone and that works fine now too.
Both PC's are completely different including the operating system yet both displayed the same problem last week and both now work fine with only the phone being worked on. Combine this with the other comments here that confirm this and you still think the pc is at fault? i'd like to see some proof or some form of methodology.
Although i personally had never seen this problem before over the many winmo devices i've had i'm pretty confident that my IT systems diagnostics training is serving me well here but if you can prove otherwise i'll gladly admit i'm wrong.
sorry for the newbie question but how do you hard reset? i know how to soft reset via "clear storage". i don't have access to the manual right now. out of office.

using clear storage is performinf the software version of a hard reset. it's not a soft reset.
the prefered way of performing a hard reset is to hold down both volume keys (make sure you do it firmly so both make contact) and then quickly tap the power button (do no hold it down at all) then hold the volume buttons until you see a warning. the rest will be obvious (printed on the phone screen)

Sorry mate, *perhaps* your IT systems diagnostics training is serving you most complicated solutions, whereas *maybe* there's more simple solutions : (1)check if there's a firewall program running that block the phone's RNDIS driver to be "seen" by the PC, or (2)a case of bad USB cable, and then (3)your *methodology-proven* trouble-shooting method.
I can say that because it happened to me, where after I take care of the firewall program, the phone gets detected immediately.
Cheers, mate.

First, most modern firewall programs actually have application detection and notifiction systems. Now in cases where the rndis connection has been working and no modifications have been made software wise this is instantly ruled out. In your case i would look at replacing your firewall with something a little better
Next, (and we will use my personal case for this as i'm sure it will be global for this thread) i have one usb cable for my leo - one - and considering, as i said above, after i hard reset and using the very same cable as before i have proven it to work. so moving on.
my method of testing is a pretty standard method. The training is only of any use for tracking the fault diagnosis. Being able to this do allows for an accurate analysis of what is going on at each stage of the connection process.
Seeing as the op has hard reset the device we will see if it is really the PC or not. i'm positive it is the phone that is not working correctly in this case but we will soon see.
Interestingly I have two notebooks, one for work one for home both run WIN7 Pro (Work one is a SOA standard operating architecture). My work notebook did see my HD2 for a while then stopped, my home notebook still syncs without an issue using the same cable. I can only assume by proccess of elimination that it is not the HD2 and that the problem lies with something on my Work notebook.
SOLVED: It was the stupid cable. I did a factory hard reset and plugged in. No dice. Do I grabbed my spare cable and presto. Fired up immediately. Thanks everyone.
Since upgrading the Galaxy S to 2.2.1 which I absolutely love - must faster than anything previous, sleek, really well done, I've just noticed for the first time that my USB doesn't seem to work.
The computer sometimes sees it but just says the device is malfunctioning, the phone sometimes sees the PC and gives a menu for "ask on connection", but Windows just does not know what this device is at all.
Suspect I may have to reinstall the drivers fully in Windows, remove it completely and try again, if it actually showed up as an unknown device in Device Manager.
I do need to try another PC and cable just in case, but this is what Im having at the moment in Windows:
USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.

I would go with a windows problem and remove the usb drivers/Kies .
Followed by fresh install .

You can find a link to the usb drivers in my signature.
I think its a little more problematic.

I've done a quick search on this. Hopefully this is as simple as doing a factory reset and format the internal sd.
If not, then Im off to a samsung service centre I think.
Any further thoughts?
:-(
Factory reset the phone, but the USB port still is not working. Charges fine, but don't connect over USB to the PC.
Can it be in debugging mode. Try to switch between mass storage and kies.
Probably you have checked that already..

the same problem from me i tried all but the usb is not working at all. I flashed kernel , i flashed rom but nothing .
Now i am looking to install untouched rom in order to give it to service but when i am trying to flash from recovery i get an error . Any suggestions?
This may sound dumb, but it could be the USB port acting up (loose connection). Try wriggling the cable around or use a different port.

Right, I've tried all available USB ports, two different computers, two different OS's. The phone just does not register a USB data connection. It only recognises AC charging according to the logs.
I think I have a broken USB port on the phone as if I jam the connector in at an angle on the phone, it sometimes registers the data connection but its far too unreliable.
Development mode don't work, Kies, Mass Storage etc... anything. Nothing works.
Factory reset doesn't make it work.
I can't even flash a new ROM as the phone is not detected in download mode.
I've got the phone booked in at a Samsung Service Centre now. I've seen a few webpages referencing corrosion. I tell you what though, this phone has been protected way way more than my old N97. I've had so many phones and not one has suffered from "corrosion". So let them just try and say it's my fault. Im ready for em.

Try cleaning your phone usb port. A guy named omersak had the same problem, and he had solved it. Search for the thread started by him, and how he has solved it.
I hope you can solve it without going to the service centre. And good luck.

Definitely trying that first - thank you to all the people that have been doing the investigation.
It sounds to me like Samsung have got a bad batch of USB connectors that should be replaced under a factory recall.
I don't use mine in a shower, or sauna, or anything like that, I don't even use it in the rain.
The closest it gets to any humidity is being in my shirt pocket from time to time.
Im going to get some meths or something like that and some thin paper and see what I can do with that. Im just off to Homebase!
there are similar problems on the galaxy 3 series where usb suddenly stops working. the following solutions seem to work there:
1. dial *#7284# to open "PhoneUtil"
2. in USB section, switch to modem, and then switch back to PDA
if that doesn't work: reboot into recovery and select "wipe cache partition"
*hth*
I've tried both of those before I start splashing the methylated spirit around. Still no joy.
Wipe Cache don't work, as well as wipe data/format sd/restore factory defaults etc.
I think I've got a 100% hardware fault.
@OP,
I am terribly sorry about your case. Looks like you need to make that trip to the service centre.
At least you have tried out every possible means known.

Also tried the meths. No good. :-(
The USB just started working yesterday. Still a bit intermittent, but when it gets a connection, it maintains a connection.
I've just ordered some isopropyl and a gold plated USB connector to be on the safe side
Hi everyone,
To sdjean: maybe you could read the post I sent a few minutes ago:
forum.xda-developers.com/showthread.php?p=12593413#post12593413
It might explain why your usb data connection does not always work ...

I have a Samsung GT-I9000B and I cant use it using USB.
I have 2 usb cables, I am able to find my friends phones.
Now I cant change rom cause odin cant find it too.
Alog cat shows:
E/MTPRx ( 4020 ) Battery charging. plugType = 1
E/MTPRx ( 4020 ) Not of USB charging. DOnt launch MTP APP
Any suggestion?
I'm not an Expert but 2 hints from me:
1. If you have'nt tried yet: Install usb-drivers on pc new and then connect your phone and wait until drivers are installed to your phone.
One times this way worked on my i9000.
2. Look for a zipped rom on xda which you can directly download and install from sd-card.
Sorry, I know my English is bad.

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...

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.

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

have tried everything, and finally only in a WinXP32 could be abble to get the error shown on the file atached.

or is it dead?

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
Hello,
Long story short.
Concept of the phone is, plug into pc "tada" you can access the SD Card, and the External SD Card (64gb). Always worked on Xnote14, 15, and not 21.
I did a full clean wipe of phone, fully done the switchover to Xnote21, with data wipe reset everything to a literal.
Now to "xfer" files from pc back onto phone... I have to pull the micro sd, place it in a card reader and transfer... OR... dropbox... and i'm sitting in the same room with both.....
I have checked if this issue persists, where I can SEE THE PHONE IN DEVICE MANAGER, but NOT in my computer, folders, etc...
This issue persists on my pc AND laptop. Laptop = Windows 10 Tech Preview. PC = Windows 8.1 Pro. (Both 64bit).
Have tried reinstalling the following drivers. SAMSUNG_USB_Driver_for_Mobile_Phones.zip & Using Kies 2 or Kies 3 to "troubleshoot/reinstall driver". NO DICE. Even after rebooting several times.
Have tried to "uninstall and DELETE DRIVER" from device manager. NO CHANGE.
Am I missing anything OBVIOUS...
When phone connects, I naturally have on the phone, The usb pc connection tab thing, that lets me click camera PTP, Media Device MTP, or Media Device (USB 3.0). And NEITHER function for showing a "drive like object" to let me connect phone to pc and browse directory's that are accessible.... ie dcim......
I seriously feel like i'm missing a super expressive facepalm moment, and would love ANY help whatsoever... aside from smashing it...
