[Q] USB Device Not Recognized - Galaxy S I9000 Q&A, Help & Troubleshooting

I realize that this is a common issue, but I figured I needed to post it since I've exhausted all the options I know.
First of all, my phone is running stock JL2 with hardcore's K13a kernel - one day, it stopped getting recognized by my PC. All I would see was the message "USB Device Not Recognized". I need to connect my phone to my PC for file transfers and mp3 sync...
Here's what I've tried:
- All four options for USB connection
- Debugging on and off
- Uninstalling all USB Root Hub drivers and reinstalling
- Uninstalling and reinstalling Kies
- Installing USB drivers from the XDA forums
- Three different cables (I have extras)
- Three different computers (all of which work fine with my Captivate and used to work)
Any ideas?
I don't want to flash a custom ROM since it will kill the internal SD card (I have a Bell I9000M)
Any ideas on what could cause this issue randomly like this? Is there anyway to get it recognized in some other mode? Could it be related to my kernel?

Tried my last option (that I know of) and tried a different kernel (damienGTO's) but still getting the issue...
any suggestions?

Would really appreciate any suggestions...can't so much for my fiancee without this.

what do you mean when you say that if you flash a custom ROM since it will kill the internal SD card? flashing back to stock firmware is always best when it comes to fixing problems.

The Bell I9000M has faulty hardware, particularly with its internal SD card. I've gone through four of them. Although, boone knows the real cause, flashing custom ROMs seems to accelerate the problem. Regardless, this is the stock rom that I'm seeing problems on and a factory reset didn't fix it.

I'm kind of getting this same problem and it's pretty anger inducing. I recently had my first I9000m die out on me (internal sd problem, phone lasted 4.5 months!), and I just got my replacement from Bell. Now I can't connect this new one, despite any attempts at connecting, reconnecting, and installing and reinstalling drivers/kies.
It's killing me. I do notice I'm getting some MTP USB device installation error/failure when I try to connect the phone
Edit: I actually just tried plugging me new I9000m into my old no-longer-used laptop and the phone connected properly. My old computer has Vista, and my new main computer has 64-bit windows 7. Could be a part of the problem?

I thought it was a driver issue, but my Captivate connects fine. I've tried win xp and win 7 and have the issue with both.
Weird thing is that it stopped working randomly. Could it be a driver conflict?

Would really like some help on this... I can't connect ODIN, and therefore can't flash the stock firmware/kernel, and therefore can't return this for warranty...
Any ideas? I'm out of ideas...

Think you have gone through all the steps .

Thanks... just needed validation.
I wasn't sure if I should try loading a Gingerbread ROM to see if that resolves the issue.. but it just seems more and more hardware related.
I also can't get a lock on GPS, despite having tried about 5-6 different modems. Hardware is failing here...

[Q] New Kies doesn't connect with phone

Hello,
I read about the froyo rollout and I fired up Kies. It prompted me with an update and I've done it. After that my SGS can't connect to Kies: the app on the mobile keeps restarting and it doesn't stops. The only way I found that lets me connect is to restart the phone, be very quick and connect it very early. That way it will work, otherwise there is no way. I can't browse my files or anything. Is there a way to solve this?
I have the same problem... Most of the time I get the flashing back and forth to the MTP app. Sometimes (very rarely) it connects.
Try clearing your caches. Download Cachemate for root. You need to have root enabled for it to work.
Also search for FileSearcherforKiesFix and look at the guides for that.
At the moment I can't get anything to run but you may get lucky.
Try to remove your sd card and restart

Same issue here on a bell i9000m. I thought i messed up the drivers some how, but im glad to see im not the only one. If you look in device manager, you will notice the mtp driver is not installed properly. Several attempts to manually reinstall driver failed for me.
Win 7 64bit.

Hi.
I am also with Bell on an i9000m and my kies does connect to my device but some things arent working properly.
Example... I check for new firmware (which there isint any yet) and now i get an option to back up my contacts before i flash. I tried this and after about 5 mins it comes bqck saying that there was no response from my device.
This is a bit worrysome for me as i have read some people in europe who were flashing to froyo had the upgrade stop and hang about half way through the process which essentially semi bricked their phone and they had to flash back throuh odin. They said it was like the phone had become "non-responsive".
Anyone else here with a similiar issue as mine? Any advice?
Thanks...

Kies is the worst POS pice of software I have ever tried. I spent 3-4 hours getting Kies to connect to my phone in order to update to Froyo. Installed drivers, unistalled drivers, installed again. Unmounted cards and connected. Unmounted and remounted.
What finally worked for I problem I had with a flashing MTP Application was to delete the contents of the internal SC card.
This only became an issue for me when i used kies to update to jh7. Now everytime I try to connect to kies, my phone not only unmounts both cards, but will not let me remount. i have to reboot the phone just to get the sd's working again. I tried yanking the external and all that did was throw my phone into a borkfest, and that simply makes zero sense. . .

[Q] Evil problems with USB-connection

Hey fellows!
I've just been lurking here a lot, but now I've exhausted all my options concerning Galaxy S and its odd USB-behaviour.
Problem Summary
Kies doesn't recognize my Galaxy S, it just keeps "Connecting Device" until infinity. Odin doesn't work either. It seems to recognize my phone, but gets stuck on "Setup connection" -part.
I can access my phone even in Kies mode with Windows Explorer and browse the files.
I'm running Windows 7 x64.
I'm stuck on stock 2.2 with Voodoo Lagfix, and basically just want to either install 2.2.1 or Darkys Rom.
Device Manager lists following
In Kies mode: Samsung Android USB Modem, GT-I9000, SAMSUNG Android USB Composite Device
In Download-mode: Samsung Mobile Modem #4, SAMSUNG USB Composite Device
What I've tried so far
1: Different USB-ports
2: Installing and uninstalling drivers, both with and without Kies, even both the 32 and 64 bit versions.
3: "adb reboot download" with Odin already running - same result
4: USB debug mode
5: Disabled Voodoo Lagfix
6: Resetting to factory defaults, formatting internal SD and removing external SD.
7: Probably something else too, this is all I can come up with right now.
The #4 on the Samsung Mobile Modem leads me to think that some drivers haven't uninstalled correctly and might screw with the connection. Is there any way to completely destroy the drivers from my computer? So far I've gone for the standard Add/Remove Programs-approach in lack of better knowledge.
Any further suggestions?
Best Regards,
JKase

Really? I've not seen anything exactly like this. Maybe I have a talent for missing relevant stuff?
I'm running Windows 7 x64.
Kies dont like win 7 x 64
Personally i would wait for official Gingerbread release rather than flash a custom rom .
But a workaround that would probably work is to undo lagfix .
Build a rom in the rom kitchin .
Use a card reader to transfer rom file to external sd card
Then transfer from external sd card to internal sd card and flash .

USB issue

Hi,
I currently encounter a problem with my Optimus 2X.
I can use my usb port to load the phone but when I plug it in a computer (I tried with several computers running XP / seven / ubuntu ... and several cables). But my phone doesn't seems to be recognized by the computers.
I'm running 2.6.32.45 cyanogenmod. I wanted to go back to the original rom but my backup seems corrupted
Does anywone knows how I can go back to the original rom ? (hopping it will fix my usb issue ....)
regards.
Uninstall the old drivers, and download v3.6 from lg's site it has fixed this issue. =P

Even if the coputer act like there is nothing plugged ? On several computer I used the phone wasen't recognized as a plugged peripheral (even a usb key).
I had the same problem, v3.5 of lg united driver was cqusing it , when I updated it got fixed just uninstall reboot and install 3.6 worked for a few more peps
Sent from my LG-P990
Thank's a lot it works perfectly !
I now encounter a new problem, when I try to update my phone using the LG software, it stops at about 30% (looks like it's impossible to connect the phone with the software).
Edit -> I've found an old stock rom and installed it on my phone : everything works perfectly thanks a lot !!!
Guys
I'm running CM Nightlies and I can no longer connect my phone to any pc via USB.
Some have said I would have to flash phone back to an original rom in order to fix then flash CM back over it?
Is this really only way as worried will lose all my internal drive stuff.
You can try to change your drivers it works very well !
If you wan to save your stuff without using USB you can use FTP thrue à WIFI to send stuff on your PC.
I got the same problem since about 4 months. When connecting the phone to the computer, no usb icon appears on the notification bar, also there is nothing happening in the device manager on the computer. Charging always works.
This is still confirmed after using different computers, different usb cables, different usb ports, and 4 different versions of the drivers (up to the most recent 3.6 drivers) even it should still show something even with no drivers. This also occurs in "software update" mode.
Also I tried different ways of plugging in the cable on the phone side (slow, fast, with pressure up/down/side).
This is with CM7, CM9alpha, and just for test also with MIUI.
The odd thing is, in this time span, it randomly worked about 4 times in these 4 months. Last time was just after I updated to CM9 alpha it worked the first time I plugged it in (was surprised with that), but it stopped working too.
For me it seems it's something with the usb chip set in the phone.
The problem here is, returning the phone for RMA will cause problems with CM on the phone, as they probably will say it's because of a custom rom, and there is no (easy) way to get stock rom with branding back on the phone (the only one maybe with a nandroid backup of stock from someone else?).
I'm having the same trouble as dedors. Absolutely no USB data connection. Can't get anything going in nvflash, smart flash, recovery, or when running normally. I've tried uninstall and reinstall the drivers, multiple cables, multiple computers, multiple OS including win7 xp and Ubuntu. USB debugging enabled, disabled, wiping the SD cards, trying with no external sd card. The only glimmer I've seen of it working was when I plugged it into my old XP laptop before and it prompted the computer to install a driver for the webcam that I'd mistakenly uninstalled. I tried cleaning out the USB port in case it had a bunch of lint stuck in it and the cable just wasn't sitting properly.
I don't know at what point it stopped working but it has had no serious abuse that could cause any physical damage.
Oddly it still charges just fine.
Can't return for RMA as it's running Cyanogen 9 and I've no easy way to get it back to stock. I also had this problem on Cyanogen 7. I could probably flash a stock rom onto the phone but I wouldn't be able to nvflash the original recovery.
A lot of people seem to have had USB trouble with this phone.
Happy to provide any logs that may help the diagnosis though you may have to explain how I can acquire them as I only know basic flashing.
Sorry for the lengthy first post, trying to be thorough.
Thanks in advance for any help offered.
I can't think of any solution to your problem (in my opinion it seems like a faulty USB port, it seems to be "popular"), but I can suggest you a workaround... it's actually the workaround I've been using cuz I also have trouble with USB... get an SD card and a USB to SD card adapter...
Or that ftp/wireless trick that was mentioned above, I actually don't know how to do this but I would definitely like to
Yeah that does seem to be the case. At least I can still flash roms and so on. So long as it lasts me the rest of the year I don't mind grabbing a new one then.
Anyone who knows about logs for trouble shooting, can you suggest a way that I might try to diagnose the problem. If I can be sure the port is stuffed and nothing I can do will fix it I'm ok with that but I'd like to know whether I should keep looking for solutions or give up on it.
Cheers.
Hello,
I've got a new issue with my phone updating CM10 and today it's impossible to boot.
I've tried to plug it on my computer in order to flash it but got the same probleme as the first post : nothing happened when plugged on my computers.
Does anyone got this 3.6 drivers somewhere ? seems that the new ones from LG didn't works ....
I have the same problem
I how bought my phone (LG P990), 6 months old, used. I come home and try to connect it to the computer and it won't be recognized. Somehow I manage over that code 1809 # * 990 # to enter the menu and play with the ports I was able to connect to the computer and do the official update to 2.3.4. over LG software.Once again, this comp will not recognize phone (only charging), but using code 1809 # * 990 # and tampering on port settings it was able to connect to the computer.
Now after some time do stupidity and Root my mobile phone(SuperOneClick) and install clockwork-5.0.0.3 and via zip CyanogenMod 9. I tried all the ways that exist but pc does not recognize the phone anymore. After some time, the official ICS update is coming, and now that you can not connect the comp how to update mobile phone. I do a recovery back to the official Android 2.3.4 (I had to change the partitions, 2.3.4 and ICS use different sized partitions) and I run a mobile phone that is again official 2.3.4 and try entering the menu (1809 # * 990 #) by tampering with ports settings I tried to make comp to recognize the phone but to no avail. I tried to change the usb cable, use a different USB port on comp but nothing, no response just recharging.
After googling I managed to find recovery from ICS V28g and I managed to install it to have a functional phone. I contacted 2 service both refused to accept phone because rooted. I tried all the tricks without battery holding vol + and - to enter into APX mode, nothing then Power and vol - S / W mode that worked but comp ga would not recognize until now even that does not work (appears LG logo and when S / W should appear then goes off) and all the other tricks that I found on the internet, reinstall the drivers, I do not know what else.
Oh yeah and I noticed entering the settings on mobu System Settings / About Phone / Software Information / Baseband version - unknown

[Q] computer wont recognize phone after gingerbread

... and two buttons have different function; back and search.
i am from canada and have an unlocked galaxy s gt -i9000 (sgh-i896). its originally on rogers ut i use fido on it. it was rooted and running fine on froyo. then i think i stupidly upgraded with some wrong files. two buttons don't work and the computer will only recognize it as a memory stick when i have the micro sd in. it goes in to download mode, but the computer doesn't see it, in both oden and kies. i have tried with usb debugging. nada. the reception is horrible. im new to androids and have searched many forms. i keep getting close to the answer but its not for my device.
pda i9000xwjvz
phone i9000xxjvt
csc i9000oxajvt.
i searched around and found that the "i9000xxjvt" is for the uk captivate. seeing as i live in canada and this is a rogers phone i see this as being a possible problem?
i have done a factory data reset. no good. is there any way to update or downgrade so that i can start messing around with my phone again?
i hope you can help
See the Sticky Thread in the General Forum -- "Captivate Connection Issues..."
If that helps, then u can go to the "Stock Rom One Clicks" that is Stickied in the Development Forum and choose a stock to go back to.

The i9000 and the i896 are different phones. You can't simply flash files for the other one and expect them to fully work, unless they are made for that purpose. The i897-i896 is Captivate, i9000 is the Galaxy S.
Make sure you have Odin open first, then plug in. I recommend trying a one click back to stock

ive looked at many connection issue pages and no luck.
i've tried the 1 click a few times. im gonna try it again from another computer soon. hopefully that will help.
and im a little confused. on the back of my phone it says i896 and when i boot up it says gt-i9000? so how are they different?
**update
so im trying 1 click from a new computer and no good.
is there a way to reinstall an os from the memory stick?
U have an i896 phone that has a ported i9000 rom flashed on it.
That is all.
U may want to give Heimdall a try. It uses different drivers and so may work where Odin hasn't.

It actually sounds like he has an unported firmware. That's why the buttons don't work right. You also have different bootloaders. Download mode can be achieved by turning phone off (pulling the battery then replacing it is easiest way). Then hold volume down (not volume up and down) and plugging usb in. As for drivers, uninstall the drivers you have. Look in program files for a folder labeled Samsung and delete it. Restart your computer. Reinstall drivers. As said, Heimdall might be a better route to take since it uses a different driver.

You have a Rogers Captivate that has i9000 bootloaders on it. If you didn't flash them, then somebody else did before you bought it. I think you are trying to run unported i9000 ROMs. i9000 roms only work if somebody reorients the kernel and modifies a few parts of the ROM.
Anyway, download mode on i9000 bootloaders (from powered off state) is Vol down + USB. Then... well what do you want to put on it? Stock i896 Gingerbread?
yeah id like stock i896 gingerbread. i have no problem going in to download mode.
ill try heimdall and get back to you guys.
usoimon this
so i tried with hiemdall and tried to find my phone is zadig but no luck.
i can go in to download mode no problem. do i possibly have to get the i9000 driver for my computer. and if yes which one in particular?
http://forum.xda-developers.com/showthread.php?t=1351224
Read through that again. The same driver package should work for i896,i897, i9000.
Try a different cable, and make sure to use the proper usb port.
ive tried all my usb ports, new usb wire, different computers. ive followed may walk troughs. uninstalled and reinstalled a bunch of different driver packs.
phone goes in to download mode no problem every time. but both odin and heimdall don't recognize.
when the phone is powered up it goes in to usb mode and says connected but on the computer the usb doesn't see anything. no pop ups in the tray or anything.
id this a lost cause? am i missing something? im usually pretty good with this kind of stuff...
*update.
ive been reading all over the internet and have found that it may be a hardware issue. maybe happening randomly after i had installed the gingerbread.
is there a way that anyone would know of to update my firmware through wifi blue tooth or micro sd?
FIXXXXED!! woohoo
so i went to my brothers who sold me the phone and it worked immediately. i guess his computer remembered it. i dont know why nothing worked on my 3 computers with all the drivers and stuff that i tried. thank you for all the help.

USB-connection (Smartflash, NVFlash, Data-transfer)

Hi,
I've search thru the forums and tried several things, but haven't found a solution.
My problem is that I no longer can make a USB-connection to my O2X.
The only thing that works in the micro-usb is charging. What I tried:
- Smartflash (power-up without battery while holding vol-)
- NVFlash (power-up without battery while holding both vol-buttons)
- Ordinary USB-connection (flash-drive)
- Cleaned it for dust
All of this was done on different windows machins (WinXP and Win7), all USB-ports and different USB-cables (inlcuding one that I know has worked before). Windows don't even show me the device.
The reason why I want to flash is that I think the current baseband (that I flashed) is not the best for my phone. So I want to try another baseband.
Do any of you have a suggestion on how to fix my phone or is the hardware toasted?
Best regards
Anders

You may try in a virgin PC where no USB drivers have been installed. Best would be format PC reinstalll WIN OS and try NVFLASH or SMARTFLASH after installing LG USB drivers. I have also faced similar problems and solved them in different PCs either friends or office. I somehow feel LGs drivers are badly written and not very smooth functioning. In fact I (and many others) have bricked O2X trying to upgrade to official GB updates by using LG PC suite and drivers.
This is only my suggestion. I did not had to format my PC any point of time. Don't curse me if this fails. This is only one of the trials and errors.
Maybe I should try from a Linux live-cd to check if it's windows or the phone who's acting strangely.

I got the exact same problem and after searching the net there are a lot of people having the same issue too.
Don't want to sound negative but the majority never got it to run again. For some it automagically started working again.
I got it to run only on Stock Froyo, no stock GB and no ICS with all the ICS Kernels available.
The thing which helped me on Froyo was: http://forum.xda-developers.com/showpost.php?p=28985033&postcount=5
Unfortunately CM9 has no secret menu.
I once had it recognized with Jarvis Kernel on Paranoidandroid for a second and had a hotreboot. Then never again.
I'm pretty sure the PC and the LG Drivers make no difference in this case, as I got 5 different PCs running different OS for testing and they never made a difference.

Does the ROM has anything to do with Smartflash- and NVflash-modes? My guess is that they have nothing to do with each other. So my problem should persist even though I try different ROMs. Correct me if I'm wrong.
I'll look into the Froyo-topic you linked to.
Strange. Now it suddenly works again. I didn't do anything from the last time. That's odd.
I don't think that the ROM specifically has to do with the problem.
Stock Froyo just happened to be the only ROM where switching USB connection modes made the device seen in device manager on Windows. (Although it required manual .inf driver clickery.)
I'm sure missing USB connectivity affects people in NVFlash as well.
In my case I can't do **** ranging from USB mass storage when booted up, ADB or NVFlash when booting.
However restoring to the Froyo nandroid makes everything working for me again.
oh oh, it looks like the same issue that i had... No PC-connection (Win/Linux) recognized the mobile via USB. No Chance to get it back to work.
I flashed back to stock (very difficult without NVFlash...) and then send it back LG Service for repearing. After three weeks i got it back. They changed the hole mainboard so i got a new IMEI but USB works now again.

Yeah. It stopped working after I booted a couple of times
And it was only semi working, it didn't want to go into Smartflash-mode, only NVFlash and Flash-drive.

Nope, as I'm quite sure that it's not a matter of drivers.
Windows don't even detect the phone. So I think that the phone doesn't present itself.

Since you already tried changing cables, computers, and even windows & Linux, and since it works on and off, You're right - it isn't the rom nor the drivers. it does sound like the hardware is messed up where the cable connects.
Any chance you can get it serviced? Hope your warranty covers it.

Same problem, no solution
Hi,
I seem to have the same sort of problem with my phone.
I used to be able to connect my phone to my computer just fine until I upgraded it to Gingerbread. Or that is at least the last time the USB connection seemed to work.
I have looked all over the internet now to find a solution to the problem but can't find one. Hope you guys could help me on this.
My phone is an LG optimus 2x P990 with a stock ROM gingerbread 2.3.4
LGE Version LGP990-V20r
Kernel version 2.6.32.9
I've tried so far:
- rebooting phone and pc
- factory reset phone
- Use other pc's => didn't work
- Connect a samsung phone to my pc with my LG cable => did work
- uninstall and reinstall all the necessary drivers
- mass storage mode on and off
- Installed android SDK and looked for adb devices, none shown
- phone doesn't show in the computers device manager either
Although when I do connect the phone it starts charging and if I go to the tethering settings it does recognize the fact that it is connected through USB.
So why can't I get my PC to recognize the phone.
I really need it cause I would like to root my phone to install a custom ROM.
I have tried rooting it with Gingerbreak as well, but that doens't seem to work either.
Thanks for the help
I just made a recovery.log in CWM:

It mentions something about USB in the bottom. Maybe it's a software issue after all?
