[Q] All of sudden SGS not recognized via USB? - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi Guys:
I have a SGS from Bell Canada, installed Kies on my PC home computer. Was having the familiar problem of connecting the phone to the pc, but finally solved the problem, thanks to tips from this forum.
I recently upgraded to JH2 via Kies. I also have connected numerous times using mass storage option to transfer large media files.
Everything was working fine until I tried to connect to pc today (as mass storage), and got a message from computer saying "USB device not recognized". I tried to connect via Kies but no luck either.
I thought it was a problem with the USB driver. Tried uninstalling and reinstalling "Samung_USB_DRIVER_For_Mobile_Phones_x86, v 1.3.450.0", still couldn't be recognized.
The phone itself doesn't seem to know that it's connected to the pc either. It doesn't do anything, just sits there. And there's no option to unmount the internal drive from the drop down menu.
Any suggestions would be greatly appreciated!

that is exactly 100% what i had 2 days ago

for some unknown reason, it works perfectly fine without me doing anything different now.
it's like a lady's menstrual thing, comes and goes without any warning

Are you using a third party launcher?
If so try switching back to TW first.

[Q] Computer connection problem

Hi,
I have searched, I have trown, I have do many things but cant fix this one. I was up till 5 in the morning last time but nothing. The problem I am getting appeared when I changed the usual samsung cable (which I got in box) with Nokia one, since I lost the last one Samsungs. The cable and everything is fine because it works on my notebook and there I can do everything normally.
So whats the prob:
I somehow connect my phone to the computer via media player and I can do anything with files on my phone, I can copy them to my computer BUT I cant do it vice versa, I cant copy nothing to my phone. Its just saying discovering ... and it will stay like that. In mass storage (if I get him to there ) it will lag so I have to unplug and plug it again.
Mom has the same windows 7 as me.
I have a high feeling that this has something to do with my computer being used to cable used before and I would have to delete some file from my computer (phone was already formated) ...
Oh and I have used every single USB on my computer, which is I think around 10 usbs
Restarted the comp and the phone dozen of times, still nothing.
Debuging mode, nothing appeared ...
I tried connecting to samsung kies, it wont connect, it just says connecting to a device.
Guys if you help me, my phone and I will be gratefull forever
Update: I have formated my computer also, still the same!
Update2: I will send $10 to paypal to the one who helps me with this one!
I had a similar problem, i would first ensure, that the Device isnĀ“t connected to a USB Hub, but directly into the Computer. Sometimes the front USB Panels acts like a Hub, so if its not a laptop try to plug it in the back of the computer.
You said, you already formated the device? How? If you can do this again, then make a wipe. Go into the Recovery Mode with the 3 Button Combination and select wipe. After reboot you should have a clean device.
Do you have a external memory card inside? If yes put it out.
Now connect your device to the computer, wait until all drivers are installed. If you get any problem right here, then go into Kies and on the left top Corner where it says Kies, select Driver recovery. It will automaticaly try to reinstall the drivers.
After that you should be getting a connection to Kies.
Tried, and other then loosing my massages and contacts I didnt achive nothing :S

Please help - I have tried everything I can before being advised to register here

Hi,
I have a Samsung Galaxy S on the O2 network in the UK.
Before registering here I have tried my best to sort this myself but I really do need some expert advice now. Please!!
I have tried and tried to update the KIES software but no matter what my PC will not connect to the phone it just says 'connecting' and hangs on that
I've tried on an XP machine and a Windows 7 machine and neither work
I'm currently on software 2.1 and would like to update to 2.2
Are there known problems with connecting the phone to a PC?
I've even tried connecting it so the PC would just view it as an external hard drive but again it doesn't connect and the PC does not recognise the phone.
I can't transfer any music or videos to the phone at the moment obviously and that's what I'm hoping to achieve with some kind help off here. I'd also like flash player which I believe is part of the 2.2 update?
Thanks in advance

Hi
I take it you have an external micro sd card in the phone? Mine wont connect without.
If you do, you should check whether the drivers are ok by connecting via USB. Goto settings, "Wireless and Network", select usb settings and click "ask on connection". Reconnect the usb and the phone should ask you what connection you want, click mass storage.
If that fails, probably a driver issue. Uninstall Kies and samsung drivers and reinstall the latest version of Kies (google Kies)
Thanks for all the suggestions, I'll do what was advised and report back
I'm assuming once this phone is updated it's a dream to use!
Cheers
I personally find it's a dream to use if you're using the modded roms..
That does kinda void your warranty though
Just a few tips which entered my mind:
- older versions of Kies do not connect if you changed the launcher on your phone from touchwiz to something else (i.e. Launcherpro or Zeam)
- it's strange it doesn't even connect in storage mode. How are your usb settings (Settings, Wireless & Networks, USB Settings), is it set to Kies or "Ask". When set to Ask or Storage Mode, you still should pull down the notification bar when connecting to make a choice.
- does the pc bleep to indicate it at least senses a device attached? Have you tried different USB ports?

[Q] Windows "USB Device Not Recognized" error

Does anyone else have this problem? When I connect my phone to either my laptop (winXP) or my desktop (win7x64) I periodically - constantly, really - get this message:
"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."
When I click the message, it identifies my phone as a Generic USB Hub (4 ports) with the first child being a USB Mass Storage Device, the second being the problematic "Unknown Device" and the last two are "Unused Port"s.
This happens whether the phone is in charge-only or mass storage mode. I tried installing the autoplay drivers and that didn't help, so I uninstalled them. No hubs are involved - I've always plugged straight into the tower or laptop. I've also tried two different quality (first party Motorola) cables.
Mass storage mode works fine despite the error - I can access the Internal storage as well as the SD card. Is this a problem with my phone, or am I missing some software on the Windows side?

Thanks for the suggestion major. I tried those drivers with no luck - the message still pops up frequently in both charge and mass storage modes.

Odd... I had issues with the original drivers, but once installed, I never had another prompt again.
edit: I had it one more time, but it found them and installed them
that's very interesting. i also use 2 machines--one with xp and one with win7. my usb connection worked flawlessly on both. fyi...my connection default is mass storage, and i've actually never tried the other options. i wonder why the difference? did you make any changes? are you rooted? i am not.

Hi gr33nT,
Thanks for responding. I'm 100% stock at the moment, not rooted or anything (though it will be soon ) Sometimes I use charge only if I have it connected to my laptop at work but I still want to listen to music from the SD card. I may see if I can get Verizon to swap out the phone, the message pops up all the time and it's getting annoying...
A quick follow-up on this one: I tried the stock LG cable on my win7 machine (I had been using moto cables). I installed BOTH the bootstrap drivers as well as the LG drivers from the web - still happening. I rooted with these drivers via S1C so I know the drivers are good. If nobody else has run into this, something is probably wonky with my phone, so I'm probably going to exchange it.
For mine, every time I connect, it asks me if I want to install bootstrap. Even though, they have already been installed cuz I am rooted.
I've had the same issue both as stock, and rooted and in every configuration with the phone and PC you can think of. I've downloaded the drivers and installed them from both the phone and web site all to no avail. This is really getting annoying.
I hope someone has a fix for this.

Hmm...that is troubling. I'm still having the issue running the stock rom and rooted, now. When I get time I'm going to drop by the Verizon store and hopefully they'll replace the phone - I suggest you try the same, as I doubt it's the computers we're using. My win7 box and winXP work laptop could hardly be more different!
I doubt a replacement will fix anything, I experience the same thing as majorpay. Drivers worked for a while and then it started asking for it again. This also causes issues when using usb tether as its connecting and disconnecting. The issue is not present when used as a mass storage device.

Hi bwhxeon,
The issue (USB device not recognized - it sounds like you're referring to the autoplay driver installation) happens for me in mass storage mode also. I believe it has to be the phone as I've never had this problem on any of my PCs with my OG Droid or any other USB device. With this phone, I have the problem on all of my PCs.
I had the same problem. The error popups seemed random at first. I noticed if I enabled/disabled the WIFI on the device while it was connected, I could make the error popup.
I ended up getting a new replacement device when I also noticed the 4G Hotspot wasn't working either even after a factory restore. There was definitely a hardware issue with the phone.
USB Unknown Device
same issue here.. when using ADB though I have to set to Internet Connection then it goes away for a while until I want mass storage or just charge from USB again, then re-appears.
LG is not like most other phones as in usb debugging only works in internet connection mode where others go into it as soon as you plug it in.
Just kind of scanned this thread but have you tried a different USB cable? I was having a problem with mine only wanting to charge with the stock so I grabbed another cable and it has worked right ever since
Same issue, two different pcs, with two different cables. Bootstrap does not load anymore so I am using the drivers from the links, both sets of Lg verizon drivers

[Q] Problem: No connection between PC and Galaxy S

Hi guys
My Galaxy S is running on Darkys Rom v10.1 and its Dark Kernel. I never had problems with this but now I can't get a connection to my PC. When I plug it in it just loads the battery and my PC says that it can't detect the USB-gadget. There's not even a notification on my phone saying I have a connection to the PC.
I already re-installed Kies and the USB drivers a hundred times and even made a full factory reset on my phone but it's still not working.
Can anyone help?
Best regards beias
try installing drivers from here http://download2us.softpedia.com/dl...93/drivers/others/usb_drivers_GalaxyS_x64.zip
it is for x64, there you can also find for x86, worked for me just fine.
these are the drivers I installed again and again and again.. they always worked but there's still the error
have you knocked or dropped it recently?
could be a loose connection to your phone micro usb port, I am in a very similar situation and I'm cracking mine open tonight to check the insides.
Also could be the cable if you're not getting any notifications on your pc of it connecting, would try different cables too.

[Q] Yet another no pc connectivity problem

Hello,
I know that there are countless other threads about this issue all over the Internet, but many of them are from a year ago and none of them have helped me yet.
I've installed every driver recommended from these threads, I've restarted my phone, my computer(s), tried a different cable, USB Debugging on and off, reformatted the internal SD card, and still no luck. Kies doesn't recognize my phone. It doesn't show up in device manager or as an extra drive.
Using TW Launcher. I plug it in, select Mass Storage, hit "Connect USB Storage." It says that USB storage is in use. Yet there is no activity on my PC to indicate as such.
I can't get my Captivate to connect to a computer.
It used to connect just fine up until I upgraded to Froyo.
Is my phone a hopeless case that needs replacing, or am I missing something along the way here? I'd love to root it or at least roll back to 2.1 somehow.
Thanks so much for looking and for any help.
Reboot into download and connect to computer, see if that works.

I had a similar problem and it was definitely a hardware problem. At first it was recognized but then it would only charge via the pc - multiple windows 7 computers would not recognize it. However, a few times it would start installing and then say "disconnected" or something like that. One of those times that I "jiggled" the connector on the phone, it started installing the driver and I didn't touch it and it finished and worked. I disconnected and reconnected and nothing again... I got another refurb and no problems at all.
Well I'll try a few more times. Just glad the Thrill is almost out and I can enjoy that one for 10 months before something better comes along
Thanks for the help
