[Q] Drivers

can somebody help me. I cant get my drivers to recognize my device. Ive installed the driver i needed. Ive restarted my pc and uninstalled and reinstalled the driver.

If you using the stock cable, this may be the issue. A blackberry usb cable works great. You should also try a different usb port on the computer. What os are you running?

I got mine to work by letting Windows Update find and install the drivers. I turned on USB Debugging, conneceted the cable, clicked to connect on the phone, then went into Device Manager in the Control Panel and found Samsung Android under USB and clicked it, then said update drivers and chose from Windows Update. Took like a half hour to get them all.

On my pc I'm using windows vista. I uninstalled driver and restarded my pc and phone and plugged in an HTC cable and installed the driver and it worked. I left debug mode on during that process. Should I have turned it off. Anyways I turn phone off to go into download mode and it doesnt recognize the device. Wth! It says to update and look for update but there isnt and doesnt work. Then I unplug cable and plug cable back in after I rebooted and I get the did not recognize error.

I have been using cables from Amazon basics, no cable issues at all. They even warranty the cable for a year.

Vista is a tough os to get the drivers working just right. If u have access to a win7 or xp x86 comp, you might have better luck. I never could get my win7 x64 working but np on win7 x86. Go figure...

USB Speed

Every time I plug in my Galaxy Nexus to PC via USB, I get a message that pops up saying that my speed could be faster if I used USB 2.0 ports and it shows me which ports on my computer (3A3A, 3A3C, etc.).
Anybody know what this is and how I can repair? I've tried moving my cable to other ports on my comp (front, back, etc.) and continue to get this message. As far as I know, all of my USB ports are 2.0...

I am guessing you need to reinstall usb drivers for your pc, phone or both.

arbiter is probably right. if you have USB 2.0 ports, and unless your computer is like 10 years old, you do, then something really trashed your usb drivers.
your best bet is to search for windows 7 usb drivers, or go to a windows 7 forum and ask there if you can't find what your looking for on your own.

Any chance it's the USB drivers on my Galaxy Nexus? How would I fix/update those?

Not on your nexus. I meant drivers for your phone on windows. There are android and samsung drivers. But honestly i think you should goto device manager and see if there are any exclamation marks relating to usb interfaces. Also check the manufacturer of your pc, gigabyte and windows update and see if there are any updates to your motherboard, specifically your chipset and usb drivers.

How will I know that my speeds could be better? I can't see the transfer rate in the dialogue window when transferring via MTP.
I added a 4.5GB Movie file and it took 15 minutes. Does that sound about right? (I think that's around 5MB/sec)

I'm experiencing the same issue except it only occurs intermittently.

I would be happy with that.

Had this problem as well. Fixed it by installing the usb drivers from Samsung website. The default windows 7 composite device drivers apparently incorrectly report that error. I have only usb 2.0 ports on my computer and got the error - error went away when I installed the Samsung drivers.

In my case it's on Win 7 and I've got current drivers installed as I recently rooted the phone. I only get this message with the GNex. All my other USB devices work fine with all the 2.0 ports.

Reinstalling the Samsung drivers appears to have helped...

[Q] USB connection does not work

Hi,
the USB port of my GN does not work for data.
If I connect it to the charges, it's getting charged as usual.
But if I connect the phone to my PC (Win8 or Linux) it doesn't work. Only the charging function works.
The PC tries to install the drivers for a new USB device but after a short time it says that it couldn't be installed.
Anyone who knows a solution?

Since you mentioned this I went ahead and tried my Rooted GNex on PC and Mac. It worked fine on PC but MAC is not finding my phone.

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!

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 :/

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.

[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.
