USB device Not Recognized

Whenever i plug in my i9000, it just pop up an error msg ÜSB Device not recognized. I'm trying to get Kies to recognize my i9000
I tried following this but it doesnt work at all.

it worked for me on kies, but i didn;t like it anyways
What i did was go to settings --> about phone --> usb settings
and try the other options (i'm using media player option, not sure why mass storage doesn't work)

Did you try to change the usb ports on your pc (stick the cable into different usb ports)?

changing the usb port does help, however when i unplug it and restart my com, it does not recognize it anymore

What OS are u running?

Could also have something to do with the number of irq's on your motherboard.
PC's older then aprox. 3/4 years have less irq's and can have trouble with much external devices

Have a look at this site from HardwareZone.com.
It's heavily populated but you only need to read the last five or so pages.

yeah i am looking at that thread too, however thanks for the link here, good for documentation as well, appreciated

keevy17, u have the phone already? If yes, you could help us resolve our questions in last pages of this thread:http://forum.xda-developers.com/showthread.php?t=694835&page=9
Q: Are there any notifications (on screen, backlight of buttons, ...) about missed calls, new mails, sms? Is there any notification when u charge the battery and the battery is fully charged?
Thanks in advance.

The default USB connection is to activate Samsung Kies. You'll have to go to settings->About Phone->USB Settings to change. If it doesn't work after changing, soft reset the phone and try again.
Caused me a bit of head scratching until I went through the options.

Now am having same problem, can'r see mass storage in my computer.

I think I read you need to enable USB Debugging then it will work. for both of you I believe.

With USB debug i can only use adb, nothing works. If i disable debug i can copy files via MTP protocol but mass storage doesn't work.
Edit.
Found the problem, it doesn't mount it self like Desire/N1 i had mount it my self. All working.

hassan,
I've not yet had a chance to use the phone yet. Can you tell me how you mount the USB in order to use it with a PC?

It was bit tricky to start with as i thought my phone is broke. First go to setting > About > USB Settings > and select Ask on connection. Plug the cable in to the and from drop down notification bar and hit USB connected then you get the option to mount the mass storage.

Thanks hassan, I'll try it later.

If you want kies to work with the phone, dont kill MTP.. But kies is acting weird, soemtimes it doesnt see the phone, but after unplug and replug it works again.. I've given up on kies actually, over 100MB to download and worst than some beta software i've used.
also, i cannot get samsung apps to work on kies, it just error or timeout.. you guys hv any luck?

I haven't tried kies yet, i'll try when i get home from work.

Anybody know how to mount on a Mac? I tried changing the USB settings to Mount/Media, no luck. Any help would be appreciated.

Nexus 4 won't connect to PC.

Hello, i have a very weird problem. My nexus 4 cant connect to pc as mass storage device.. It worked fine like 4 days ago.. I dont know what happened or what else i can try.. Already tried: usb debugging on/off, factory reset, usb settings in storage menu, different usb port, NOTHING HELPED! There are another weird thing that i spoted is that it only charges through usb when i have nothing selected in storage>usb connections menu, as soon as i try to select mtp or camera it stops from charging and nothing happens. Same problem for AC charging it wont charge when theres mtp or camera selected, and only charges as USB... I'm confused.. Are there any ways to get it working again?

I'm having the same problem.. I've just installed Windows 7 64 bit but it sees my Nexus 4 like Unknown Device.. I uninstalling the drivers and re installing them using Nexus Root Toolkit but no result for now..:crying:

Do you have a ROM or anything installed? I know with PA its a problem at the moment at times. A little more info would be nice. I never had a problem with Windows 7. I'm on Windows 8 now and i had an issue at first with it not showing up at times. But it seems to be fine now.

Just go in
Settings,
Dev options (if you not have it go in phone informations and press many times in row the Build Number, this activate Dev options)
and Disable USB Debugging,
then reconnect your phone, and the computer will see it

USB debbuging isnt working. i have no ROMS, stock android 4.3. And yes, now im running WIN 8, previuosly had 7, the problem occured after installing 8 and trying to plug it in. Its not showing in my computer neither in device Manager. I doesnt make any difference with, or without it pluged in, the only difference is that it will start charging, but then again ONLY when i disable everyting in storage>usb connections.

bump

do you have a fast charge app installed? it sounds like it's an issue related to fast charging via USB. if it's enabled you can't access anything on the phone via usb, but i think that requires to at least be rooted.

I'm on last PA 3.99-Rc1 and I just found out that if I go in Setting-Memory the appilcation shutdown .-. Never had this issue before .-.

Nothing, just read that it's a issue with PA while using last Franco Kernel nightly XD I'm going back to windows vista 32bit, so I believe the problem connecting my nexus 4 won't be any more an issue (Going back to Vista because for daily use it worked perfectly and every thing worked fine with the drivers, Windows 7 it's better, but too many issues with drivers bla bla bla XD) :laugh:

I have always used the Windows Driver from the Google SDK (Google USB Driver- As of today, Revision 8) for my Windows 7 64 bit computer and have never had a problem. More importantly there is an Update Manager that comes with the SDK, that when you run, notifies you of newer Windows drivers as they are released. That way as Google issues newer OS builds or Windows issues a new OS, I know that not only my driver but my platform tools aka fastboot/adb/etc. (As of today, Revision 18.0.1) will always be compatible. The problem with these toolkits and driver downloads all over the place on these forums is that you have know idea how old the internals are. The other obvious thing to check is a bad or intermittently bad USB cable. Also make sure "MTP" is checked in Settings > Storage >Settings > USB computer connection.

Hey, I'm sorry if it's against etiquette digging up an old post, but this part worked for me:

Fix usb
Go to device manager in windows 7/8/8.1 . Connect your mobile with usb. You will see android device or adb right click on it, select properties, click uninstall driver. NOTE: When you click this a small popup will appear saying remove software driver, tick on it and click uninstall.. there you go ..it will reinstall drivers and your phone will be finally connected.

im having the same problem . My phone shows as Unknown Device on Device Manager. Tried other cables and usb ports. I can tell that the cables and ports are not the problem since my Nexus 7 can connect without problem. Tried usb debuggin on/off, MTP on/off, PTP. Still no luck. Already tried to reinstall drivers but still the same problem. Hoping this is not a hardware issue. I already tried factory reset and flashing other ROMs

Redmi Note 3 cannot connect to PC

Hi Guys.
I have one Redmi Note 3 and I am having a problem to connect it to my pcs.
Before everything was ok. I connected the USB cable and I could transfer files between my pc and the Redmi Note 3 using My Computer.
Now, I connect the Note 3 and I cannot see the storage anymore. So, it's impossible to copy anything between pc or note 3.
I checked with several cables and different ports and in two different pcs. I cannot connect with MIPC Suite either. The Note 3 recharges normally.
I believe it's a driver version problem.
I am using Windows 10 and MIUI 7.1.6.0 Stable Version.
Thanks for all help.

Check if the drivers are updated to win10
The best way is to download them from miui.com or mi.com
Enamorado de mi Redmi Note 3 ?

Thanx mate..

Go to the Setting> Additional Setting and look for the "developer options"
if you cant see that option, go to the Setting> About phone and tap five times on "MIUI version", you'll see a little popup message "you a developer now", then go to Setting> Additional > Developer options and enable "developer options" and "USB debugging"

Hey Guys, even i faced the same problem but it got fixed so easily than i ever thought . As soon as you connect your phone to laptop using data cable, you will find an option called " Touch for more option" in your phone, when you touch on that option, it will prompt you with three option > Charging only , Thasfer files (MTP) and Transfer photos (PTP), when you click on these you will be able to see Internal storage, then you can copy paste whatever files you want Hope it helps.

Even after usb debugging, i can not see the storage in my pc

I had same issue with my Xiaomi Redmi 3s prime as i can not get it to connect to my PC but got it fixed .

did u first install moto usb drivers?

Did you try to change the USB settings? i.e. touch and drag the notification bar down and select "Transfer files (MTP)"?

USB connection detected in windows only in Recovery Mode

Today my rooted Galaxy Note 3 running Phronesis N7 port v4 ROM (Lollipop) suddenly is not showing up in Windows explorer. However, when I go to recovery mode, I can see the device in windows and browse the files without problems. The only difference is that the device shows up now in windows with the name "hlte" instead of the usual "Android phone" name.
It actually connects fine when I use "FX Explorer" app with its file sharing feature which allows me to connect via wifi with an Internet browser or any other similar windows/android browser but not in windows explorer with usb cable.
This ROM has been working great for months and I cannot think of any changes made recently.
I re-started both the PC and the phone, pull the battery, etc. to no avail.
Obviously it's not the cable (which I've anyways changed) or the drivers which they report as the 'latest' by windows, so I'm at a loss.
Any ideas ?
Thanks

Install Samsung drivers again .
Sent from my SM-N930F using XDA-Developers Legacy app

I already did uninstall and re-install the drivers to no avail.
However, I did a backup and then restored in TWRP a backup from 2 weeks ago and the problem is not there so it had to be caused by an app or a setting introduced during the past two weeks .... So I restored again the backup that I did earlier and uninstalled the apps that I remember but the problem is still there.

Did you check which USB protocol you have selected, maybe you changed this by accident. Then you connect your mostly the USB setting are available by pulldown but you might need to search in settings.
All new phones using MTP protocol, you need to have installed th media player installed on windows for driver(the samsund driver will not install this). I thing it's a buggy implementation, slow, only single file tranfer and often need to reconnect your device to work.
Optional you can select PTP which esentional simulates a camera.
In some custom roms you can select the good old mass storage protocol. Which is fast, stable but need to close every app accessing internal or external storage.

Did you set debug usb in developers options? Which USB mode is selected also in developers options?

<All new phones using MTP protocol, you need to have installed th media player installed on windows for driver >
Not true at all .
OP download and run USBDEVIEW and delete the drivers/ usb port .

USB debugging is enabled and MTP mode is the mode selected. Phronesis selects MTP by default in the pulldown which is really handy rather than having to switch from charging mode every time that you connect the cable.

Not sure how you mean to delete drivers, do you mean through USBDEVIEW? or the samsung drivers through windows uninstall?
I've already uninstalled/installed them before (see post #3).
Here is what USBDEVIEW gives me:

Try to switch off USB debugging, don't know why but sometimes windows drivers go wrong, especially when you use a different usb port and it tries to install them - I solve restarting pc plus a kick (stress relief) and Note3
