Computer stopped recognizing phone.

Just yesterday my computer stopped recognizing my phone. As this tends to be a big problem for me as I transfer a lot of files to and from my phone and computer a lot. I can't seem to figure out what the problem is. I've tried rolling back to the pre-updated driver that originally came with the phone. That didn't work. I also tried uninstalling and reinstalling and that didn't work either. I am running windows 7 home on this computer. Does anybody have any ideas?

Seems dumb, but try a different USB port/cable.

Unknown Device Driver Constantly being installed!

Guys When I connect my phone to my computer it is constantly installing unknown device driver.
Ive tried all my ports. Its a hit and miss with this thing. In a blue moon it will catch and recognize it as the samsung device. But it takes litterally hours of pulling out the battery, putting it indownload mode, uninstalling the "unknown device driver" Ive tried also updating the driver manually to the "Samsung Android USB Composite device" but it doesn't recognize it when I manually update it. The cable is brand new and it cost me like 20dollars and its worked in the past. Literally 2 days ago.
Im on Windows 7. How do I get this dam computer and phone to work properly and recognize eachother and How do I get my computer to STOP installing unknown Device Driver. When it freaking has the samsung drivers installed!!!
I got the device drivers from QBkings utube video. He is using windows 7 too so everything should be working!
Im losing my patience
Any Help guys?

I had the same issue, there is a post on here about uninstalling kies then install Samsung drivers v1.4 I think then 're-install kies. Since I did this it's been fine.

I did a google search for the samsung kies that you mentioned. Found "Kies_2.5.0.12094_28_8.exe" Installed it then Uninstalled it. reinstalled samsung drivers "Samsung_Mobile_USB_Driver_V1.4.8.0" and it didn't work.
Is that the kies program you were talking about?
Kenny this data cable has worked in the past. It cost 20dollars at staples. It says its a data transfer cable. Its worked plenty of times (however ive always had this problem.

I would still try a Blackberry cable. I have seen people go through 5 cables and a new Blackberry cable solved their problem. Also is this a laptop or desktop. If desktop use the ports in the back directly on the motherboard. I have also had the best success with deleting the drivers and letting Windows find them from Windows update.

Computer not recognizing Note 2

Has anyone had a problem with this? The only way for me is to go into recovery and mount it. It's connected as a media device.
Thanks in advance!

Ya I get the "Device ID not found" error. Kies and Samsung drivers are horrendous.

Sounds silly, but did you try rebooting your computer? I had to do this the other day when mine wasn't recognizing my phone. Rebooted computer, worked fine after.

Samung's drivers are awful. I had to install, reboot, remove, reboot ad nauseum until I finally got the drivers to work. I also found I had to connect the phone then wait a few minutes before the computer would acknowledge the phone.

specteA 187,
I've only ever had the issue if I've tried USB ports on the front of my machine. For some reason those ports can be a bit flaky.
Plugging USB into the back of my machine causes no issues. Weird.

For me, on Windows 8, I have to switch from MTP to PTP, and then back to MTP for it to mount. It sure is wonky.

Yup I tried everything. The only way that works perfectly is to mount the drives via recovery.

My phone doesn't even try to get into mtp mode :/

Try uninstalling the Samsung driver, restart PC, and install driver again. It worked for me

That is what I do to get it working under Windows 7.

I found that if my computer doesn't recognize my phone, I put my phone into download mode then reboot back to normal and the computer will recognize it. Kind of a pain to have to reboot 2x but seems to work for me.

I've had 5 Samsung smartphones (Captivate, Infuse, GS2, SkyrocketGS2, and now the SGNote2) andI use an XPSP3 desktop computer and have never had any issues with computer recognizing phone until the Note2. Odin3 works like a champ on the Note2... it's the plug-n-play recognition for transferring files back and forth that's problematic. Yes, I've uninstalled/reinstalled drivers, Kies, etc, used back ports vs front port... I think it has to do with the MTP file transfer protocol now used. Here's what works for me with the Note2 and the PC:
Connect phone to PC... phone's "USB PC Connection" box opens and you have 2 options: MTP(media/files) or PTP (camera). If PC doesn't immediately recognize device, I do one of two things which always works:
1. toggle between MTP and PTP a few times... if that doesn't work,
2. unplug usb from PC port and reinsert (either same port or another)
Windows Explorer will then recognize device and add "SAMSUNG-SGH-I317" under "My Computer" and list it under "Other" devices in panel.

I had this same problem today on my new N2. Drivers would not install. All I wanted to do was to drag my pics and music onto my SD card. I worked around this of course by removing the SD card from the Note and putting it in the adapter and doing it that way. I still haven't gotten my drivers to install. I may just get the drivers off the Internet

+1, my ONLY complaint about this phone.
I gave up trying to find a fix after installing/un-installing/re-installing drivers/kies/odin3 about a bazillion times and only getting it to work a random few times.
Not even worth the effort...
Dropbox is my best alternative. Sure sux tho...

Thanks, Should've mentioned that I've tried all of the above methods. It may be that, since I work on so many Android devices, my pc is just too full of incompatible drivers and I've yet to clear them properly. Even If i did I'm fairly certain that I'll be working on more devices and will screw it up all over again. My network is pretty quick and Dropbox/esFile Explorer is convenient so I really shouldn't complain.

USB transfer not working

Hey guys, just wondering if anyone had this before:
I am able to charge the devices, but nothing related to USB transfer works...
I am stock, not rooted, with latest version available for the Telus' E973
I've tryed 3 PCs, 2 cables, hard resetted the thing but nothing...
So far, I'm thinking I'd RMA the thing...

Does phone ask about mode when you plug it in?
Also, does the computer make any sound or showing that it's plugged in under computer or device manager?

Sounds like USB cable problem, but if you tried 2 cables the odd it's the problem are really low.

Nothing on either the computer nor the device, no changes in the device manager...

Was having same problem.
Redownload/install the ADB drivers or whatever they are, and all other drivers. Worked for me. Mainly the ADB ones.

You mean on a computer or on the device?
I've tried on multiple computer which were working before, and nothing is being "added" when pluging in the device, so it's most likely not a driver issu on the computers.

Maybe you broke the connector? What os does the pc have

Tried with Windows 7 x64 and x86 and Windows XP, same thing on 3 PC's
No reaction either on the PC's or the device.

Definitely broken connector

I'll keep you posted, I'm going to check out with my reseller tonight or mid-day.
So far, I understand that no one had this issue?
Thanks for all the input!

Got there during lunch, it's send out...
Now I'm stuck with a crappy Desire HD...

[Q] Anyone having issues mounting their tablet MTP

Is anyone having issues mounting their tablet via USB. If I check off Camera (PTP) I get access to my photos in my Windows Explorer, but when I check off Media (MTP) windows acts like it doesn't exist. ADB can't see the tablet either, but once I check off Camera (PTP) ADB can see the tablet... I'm using a windows 8 computer, has anyone heard of this happening, or is it happening to any other computers?

I have no issue using MTP. Did you install the driver from google?

You have some old driver that is blocking access.
Use device manager to remove the device and driver then reboot and try again using the Google drivers.

Yes. It is fairly typical. I had same issue on Windows 7 x64 and lived with it for a while.
Finally, I decided to fix it by uninstalling the drivers and reinstalling. It took about an hour after trying all sorts of tricks. There are tricks in quite a few threads here on xda. I'm not sure any one thread fixes every problem. So I found the solution was trial and error.
After messing with driver for a couple hours, serious waste of time, I got MTP working once. As a confirmation check I uninstalled the drivers once more and let the drivers reinstall on plugging in the device. It broke again, back to PTP. LOL
Not giving up, I tried again the next day and finally got MTP working again. This time I uninstalled drivers again, and the correct drivers reinstalled on device plug in. Since then everything has been great. I get both MTP and PTP working great.
I would try sfhub thread ideas and search around for a couple other ideas too. It will eventually work, but you have to isolate what exactly is the problem on your Windows 8 PC. Sometimes you are missing just one thing, sometimes Windows automatically messes with you.
Good luck.

I have no issues with Win7x64. Worked first time and every time since. Sorry...

Make sure you are using the usb cable marked Asus on one end that came with the Nexus 7. I had the same problem because I was using another usb cable. They are not all the same.
