[Q] Mounting and unmounting [PC] - Samsung Galaxy Nexus

I can't find the answer to this anywhere, but every time I connect my galaxy nexus to my PC (not rooted, running 4.0.1, and connecting using MTP), the device keeps mounting and unmounting...(it keeps connecting and disconnecting) even on USB debugging...it makes hard to transfer files between my device and my computer.
Does anybody have a fix for this?

Try reinstalling your drivers

And/or a different USB cable (or port on your PC) maybe.

Used another usb cable, and it works flawlessly! This is horrible...I had the phone for 2 days now...the USB cable is ****...and one of the ear buds that came with it died on me after a day!!!! i'm really starting to regret getting this phone.

can't connect to usb

i can't connect my sgs2 to USB storage. when i plug in the usb cable to my computer and phone it will charge but nothing else happen. i had stock rom before but are currently using jug 4.0. i thought it was the rom so i downgraded to 3.69. still the same problem. i mean i can do anything with the phone just can't let my computer detect the phone. i tried to reinstall the driver, nothing works. please help!
Is your cable a samsung branded one? I had that same problem but with stock rom. I used an LG branded cable and the phone would connect to the computer and charge, but would not go into USB mode.
yeah, i am using the one that came with the phone, i guess i will try to use a different one. it was working fine before, don't know why it just stopped!
This has happened a few time for me. Sometimes the phone has only needed a reboot, the wire definitely plays a big role... I bought some cheap cables that didn't work at all... some of the older roms wouldn't show USB connected unless drivers were installed (kies). An issue I've more recently unveiled is after using an MHL adapter sometimes the USB will connect for 30-60 seconds before unmounting storage again. Hope that helps
My SGSII HercuDom needs more w00t. It always needs more w00t!
I had the same problem on a stock phone (purchased in late Oct from T-Mobile store in Arizona). I would connect it to the computer and it would charge but would not recognize the USB function (for data transfer or modem use).
Took it back to T-Mobile and they overnighted me a new one for no charge. New one works fine.

USB doesn't work!

I think my phone's usb doesn't work. I tried my htc usb cable and my friends samsung usb cable.
Both my comps and laptop won't recognize that a device has been plugged in.
USB drivers of gnex r installed...
You have to turn on USB in settings, mine doesnt automatically connect.

Wow! There have been a lot of these my USB port doesn't work threads lately. I hope this isn't a problem with the Gnex. Does it charge when plugged into the wall charger?
Yea, it does charge...
And I don't think it charges from the computer, only the wall.
And of course my usb debugging is on.
Maybe it's because I didn't root it properly?
I think it may have started after I rooted my phone...
How do I double check to see if my phone is properly rooted or not?
I used the Gnex toolkit btw.
Some custom roms have kernals that break USB. Are you on stock?

Could be that your usb charging board is starting to fail. When my board failed, the first symptoms was that the computer didn't recognize my phone.
I don't know how to tell if my USB board is failing.
Yes I am running stock.
And I tried connecting my phone in both camera and media device mode.
You should return it. This is most probably a faulty hardware issue.
I can't. It's craigslist.

Check your usb cord. There is one cord at my house that will charge my phone but not recognize as a USB drive.
Have two cords and both won't. But they both did a while back before I switched phones. There a way to Odin back without Ccomputer?

USB Problem.

Just got a brand new Samsung Galaxy SII T989 from T-Mobile this week, it really is a great phone, only I have a single problem.
The phone charges, it functions properly generally speaking (calls, texts, camera, wi-fi,etc...) but as soon as I connect it to my computer it freaks out.
It acts as if I were disconnecting and reconnecting the USB cable 2 times a second. I can hear the phone making the beeping sound it makes once you connect it to the USB every few seconds and in my computer (Which is running Windows 8 x64, just in case.) I can see the "Safely remove hardware symbol pop up and disappear a few times a second as well.
This is really frustrating... I love to take pictures and videos and edit them... I'd also love to copy some music over as well...
So far I've determined it can be the cable, bad drivers, or the phone itself, I just hope it's one of the first two.

Try re installing the correct drivers or switching the usb hub. If that does not work it's most likely the usb cable, swap it for a different one and you should be fine considering you bought the phone new.
Or you got a phone with a bad motherboard which would be crazy considering its new but that kinda sounds like the problem I had

Alright cool, but how does one find currently installed drivers when the device isn't plugged in?

Ok, does it get better or worse if you hold the cable with your finger when it is plugged in to the computer and phone and move it around a bit on the phone end? If so, I even got a Nexus 7 brand new from Google that the charge cable phone end was bad and would not make a good connect and I had to use a different cable and it works fine with my tablet.
If you use the same cable in your AC charger and on the computer then prolly not the cable.
It could be something in Win8 if it is trying to scan your USB port [like maybe a whacked anti-virus].
Have you tried a different USB port on your computer to see if maybe the one you were trying to use is bad itself?
If using a USB hub between your computer and the phone try removing the hub from the equation and connect directly to the computers USB port.

I am using a HUB on a Razer Keyboard that I've always used BUT now that you mention it my webcam had the same problem. It wouldn't work with the HUB on the keyboard. I'll try another USB slot (My computer's other USB slots aren't very accessible which is why I've hesitated to try another slot.)
I don't use anti-virus and yes, the cable works perfectly fine on the AC USB to Power adapter it brings.

I love you. It worked. It's the USB hub which doesn't allow much power to go through to the connected device. Thank yo so much.

Powered OTG hub issues.

I've just received an item (OTG 7-in-1) I got off eBay which I'm primarily interested in for moving GoPro footage to external storage whilst on a trip away, no computer access.
The only problem is the Z5P I'm using isn't detecting it, but is charging from it once plugged in.. It detects the stock OTG cable with storage without an issue.
I'm just wondering if anyones come across something like this before? I've had OTG issues before which seemed to be kernel/recovery based. No idea where to start...
Have you tried plugging it in and detecting USB device before turning the power on?

I did indeed. I found that leaving the device plugged in with a single usb and resetting my phone, the hub powered up through the splash screen and has worked since. The only problem is that the phone only detects it with a single usb stick in. More than one and it refuses to find it, but once it's powered it reads all usb devices including memory cards at once.
It works now, regardless. Thanks anyway!
