Interesting problem I have had on and off. When I plug my phone into my desktop, it will connect normally, then a few seconds later it acts like I unplugged it. It's not the rom as it does it in recovery as well(both with usb-ms activated and without). I have HTC Sync installed. Rebooting either the computer and/or phone doesn't fix it, it just goes away after awhile and starts working again. I've experienced the problem FAR less when connecting it to my laptop, it will typically work there and not on my desktop when the problem crops up.
it's like this problem but it's not constantly http://forum.xda-developers.com/showthread.php?t=711616
-Edit- the device also doesn't show it's charging even when it 'disconnects'
I have the same problem. just keeps discontenting over and over it sees it for a few seconds then disconnects reconnects then off again.

Mine doesn't reconnect, it 'disconnects' and stays that way(as if i unplugged it) until i actually do unplug it and reconnect it.

I was having the same problem on my MacBook until I realized the MacBook must be plugged into power. Once plugged in everything was good. I wonder if the Evo demands more power through USB then other devices.
Yeah, sounds like a power issue to me. If you're using a USB port on a hub or on a keyboard, try one on the PC itself. Also, it could be a slow USB port or a bad cable if you are continuing to have issues. Try another computer if you can, and if you still have the problem try a different cable. Still have the issue, reflash (if you're running a custom rom) or contact Sprint for service.
Same issue here, but on a desktop PC (Dell Studio XPS) using the front-mounted USB port (not a hub). Keeps disconnecting/reconnecting, but often takes 10-15 minutes between cycles. Using stock ROM (for now, at least). Will try other ports & another PC and will report back.
Already tried different ports, only motherboard ports
Rom doesn't matter as the problem exists in both android and recovery
Don't have a different cable, however the same cable will work fine on my laptop then not work on my desktop

If it works on a laptop, but not the desktop, then it appears to be an issue with your desktop. Any other USB devices doing it?
I would check your motherboards manufacturer and make sure you've got the right USB drivers, a bios update might be in order as well.
But before all that, I've got an idea. First and foremost, try this:
Go to device manage (either from control panel, right-clicking my computer and going to properties, or searching for devmgmt.msc in the start menu search.)
Navigate down to Universal Serial Bus controllers, double click on USB Root Hub (you probably have 1 for every USB Port, so you may have to do them all.)
Click on the Power Management tab, and uncheck the "Allow the computer to turn off this device to save power." check box and see if that solves your problem.
i had this issue on my hero. it was corrected for me after i did a wipe of data and cache. i restored from titanium afterwards. YMMV
good luck
one thing you might try is disabling sense and using the android launcher. then reset the phone. once it boots up try and connect it to your pc. This was how I got mine to connect. when I was using the sense launcher it somehow blocked that options screen and the default I selected wouldn't stick. once I got the connection to my pc working this way I was able to re-enable sense and it's worked perfectly ever since.
I do not take credit for this fix, someone else on here told me to try this n it worked perfectly.

it was nothing with the rom, since it was doing the same thing in recovery.
it turned out to be the short little usb extender cable that was going a foot and ahalf from behind my pc to the side so i could plug it in easier.

Hopefully you guys can help me out. I'm suddenly having issues with my phone not being detected by my PCs when it is connected via USB.
When i plug my phone into my PC, i receive the error message: "UBS Device not Recognized One of the USB devices attached to this computer has malfunctioned, and windowes does not recognize it." from my Windows XP PC. My Windows 7 PC is unable to recognize the device plugged in.
The strange thing is that even though my phone is not being recognized by the PCs, the phone will still charge.
The phone is not in USB Debugging Mode, and I've gone ahead and flashed 2 separate Kernals on my phone, but i still am having this issue. I have tested this out with 3 USB cables, on 3 separate computers (Work (win xp), Home (win7), and friends(win7)).
2 Days ago the USB worked fine for me as i was able to flash Franco Kernal and JB onto my Gnex, but suddenly it's not being recognized by my computer anymore.
Stumped.....Hoping that this isn't a hardware issue and something that i can fix without having any downtime away from my phone.
Any thoughts?
Try other USB port and other USB cable.
Sounds like you're missing some drivers... Remove the device completely in Device Manager & plug it again. For MTP, Windows 7 should find the drivers online by itself. If you need fastboot access, you'll have to download the seperate drivers for that. I'd recommend the GNex Toolkit in that case since it comes with the drivers included (you'll still need to install them of course )

Thx for the reply,
Yes, I have been using the GNEX tool kit, though not the 7.3 version that was released today. The 7.2 version was being used at home and on my work PC. I usually install the drivers from the toolkit then plug my phone in when done. The drivers have been recognizing my phone but not since 2 days go.
I'm currently trying to find the MTP checkbox in the phone Settings to double check if it's checked, but im having problems locating it.

Could be... Charging doesn't necessary have anything to do with data transfer AFAIK... Do you see something in the Device Manager when you plug it? You might have to right click & do a re-scan to force detection.

Device Managers shows "Samsung Galaxy Nexus ADB Interface". The drivers look to be installed.
Also another odd thing, is that after i charge my phone and unplug it from my PC, it will continue to show that it is charging on the lock screen and in the top right corner of my phone. However if i go into Settings ---> about phone. It shows Battery Status : Not Charging.

You get that when the phone is running normally? I think for me that one only shows up when I put it in bootloader mode. In MTP mode it's just a media device like any other AFAIK... I'll check tomorrow when I'm back on my Windows laptop to be sure . Have you tried putting it in PTP mode? If so do you see the device as a camera or is it the same issue?

Basically the way the Nexus One talked to other systems through USB is completely different from the way the Galaxy Nexus does. The GN uses a new protocol called MTP. Your car stereo probably can't read the files on your phone because it doesn't have MTP support.
Phantom Charging Issue
So I've gone ahead and Fiddled around with my phone for the past day trying to fix my USB issue, and I've discovered that this issue may not be due to USB issues.
Throughout the day when i was playing around and trying to fix my USB recognizing issue, it miraculously started working again. Now I am able to connect to my PCs and transfer the desired files.
Upon this issue being resolved, i noticed that periodically the screen would turn on, on it's own while being off in the locked state. I observed this issue to see what may be causing this, and it is turning on due to my phone thinking that i plugged my micro USB cable in to charge it. The charging indicator on the batter flips on, and even the USB Debugger / MTP Notification is present in the notification drawer.
Apparently this is a known issue with the Battery or charging port with Gnex's. (See below the 2 youtube clips for more details for problem/fix.)

I believe my warranty is void since this phone was purchased in a different country and has had the bootload locked/unlocked a million times. Anyone else have this problem that they have been able to fix manually? Or am I going to have to cross my fingers, ship my phone to get it fixed, and hope the post man doesn't f**k up?

I am having multiple issues. The big one is that sometimes when I plug in the phone to my Macbook Pro, it decides to hang the OS. But it's really weird. It's like only the mouse and keyboard hang. Music will keep playing normally, the clock in the menubar runs with no problems, and if I press the power button the "What do you want to do?" window still pops up, I just can't tell it anything. It forces me to hold down the power button for a hard restart. Here's the weird part: I can't narrow it down to what is causing it. I can't tell if it is the phone in Disk Mode or what. And it doesn't always do it. Heck, sometimes the phone won't even act like it's plugged into a computer so it won't even try to connect.
When I first got the phone it didn't do this, but a few weeks after installing DoubleTwist (the only thing I have installed for this phone) it started happening. Uninstalled DoubleTwist and it still does it.
Any help is super appreciated. I searched around and there are similar problems on other phones, but nothing as odd as this.
Thanks!

I have had no other problems with any other devices. And for me, this doesn't go away if I wait for 30 seconds or so. I did find out a few minutes ago that if I unplug my phone, within 30 seconds my mouse begins to work again, but my keyboard still won't work. It seems as though if I press a few keys on my keyboard sometimes the mouse will lock up for another 30 seconds. Only a restart will make it all work normally.
gotcha. well in that case sorry I don't know
Ha it's cool. Hopefully somebody will know though!
have you written to apple to make sure it's ok to plug in an android phone to a mac?
are you on ICS or JB? if it's the later it could be the MTP connection that's been introduced

Hahahahaha, for some reason I don't know if that was ever an issue lol
I'm running 4.0.4 which from what I understand is still ICS. So it's probably good that I haven't attempted to upgrade just yet?
The main reason I even care right now is because I'm trying to jailbreak, but I'm having all sorts of issues. I figured I'd start with this one haha.

I'll look up an SMB reset. Haven't heard of it. Still new to Android lol
However, I googled for a while and even went nuts on here looking for it, no one has this exact issue. The other similar issues only involve programs freezing. For me it seems like my keyboard and mouse freezing, while the computer keeps going. Sometimes I can't even get the two to talk to each other. And when I CAN get my HOX to connect without freezing up the keyboard and mouse, when I run the root through terminal it can't find the phone, in charging mode or in disk mode.
Your Mac is jealous

So, did an SMC reset (when I googled SMB reset, SMC came up instead). I thought it worked, but it didn't. My mouse would unfreeze, but my keyboard would still be jacked until I restarted. And if I pressed too many keys on the keyboard the mouse would freeze back up for another 30 seconds. I am too tired to think of what I could do right now haha. Throw suggestions (LOGICAL ONES!) and I'll try it out haha. I just want this dang thing to work so I can root! :silly:
This is clearly a Mac issue. Absolutely nothing to do with the hox whatsoever.
You said that you used to be able to plug the phone in without any issues, and the only reason you want to plug the phone in now is to root it (You said Jailbreak but I presume you meant root).
Why don't you try a factory reset on the HOX and see if it resolves the issue. If it does then you can root your phone and will be installing a new ROM anyway so it won't matter that you've done the factory reset. If it doesn't then it means something has changed on you MAC and I can't help you unless you install Windows
Have you tried another usb charge cable with your phone and macbook it could be the cable is damaged internally causing a short circuit and making the usb devices play up even internal like keyboard/trackpad? Just a guess as Ive experienced a broken cable disabling usb which then works fine after reboot.

factory reset of HOX won't solve an issue with computer. It seems that you USB port is screwing up or is screwed up. See if you can connect another android device the computer and repeat the issue again...if so your USB port is jacked...BTW, u are not using an external keyboard/ mouse, are u?
I'd take the computer back to the service centre and shown them the issue...
me too...seems like MTP is not going well on mac(

^^^^ Now THIS I haven't really thought of! And, actually I think it makes more sense than a software issue. I was having problems sometimes even getting the two to talk to each other unless I moved the cord a bit. I've dropped the phone from my nightstand a few times and it has landed on the cord, so I wouldn't be too surprised if either the cord is messed up or (God forbid) the port inside of the phone is messed up. Sometimes if I had the HOX in disk mode and moved the cord just a bit then it would suddenly eject and often freeze. I have another cable back home, so I'll grab it when I'm there tonight or tomorrow and see if I have the same issue!
So I installed the latest Samsung drivers on my Win 7 desktop with the intention of using mskippen's Note 2 toolkit to do a nandroid backup of my phone. After rebooting the behemoth I plugged in a USB cable into an open port and then plugged in my phone. The screen of the Windows machine went black and the cooling fan kicked into high gear! I couldn't even do a three finger salute (ctrl-alt -del) to get to the boot menu. I had to YANK the power cable!! I rebooted and tried again, same result. WTF!
Has anyone ever seen this happen before?
Before you suggest reinstalling the drivers - I rebooted the desktop one more time and plugged the phone in even before the computer had a chance to initialize the USB controllers (I.e, during POST) and the exact same thing happened. Seems my phone is out to literally assassinate my desktop. But here's the kicker - I've successfully plugged this phone into the computer before. So what is going on?

Sounds like a short circuit, try a different cable, try a different USB port (preferably one on the back of the computer).
FYI, USB ports are hot during POST (otherwise your keyboard would never allow you to get into the BIOS).

Hi all, I've been lurking the forums since bout September of 2012. I haven't really been posting here, mainly just gathering ROMs, kernels, help etc.
Anyways, my Nexus 7 isn't being recognized by Windows 8, Windows 7, Windows Vista, or even Ubuntu. this leads me to belive this is caused from the tablet. I have installed numerous drivers, but with no luck. Recently, I noticed when I boot into recovery, and the tavlet uis on the Google screen, my computer recognizes it as, "Unknown Device." Soon after it passes the Google screen and boots into TWRP Windows can't detect it anymore. My tablet says it's connected via AC, not USB - which is probably why I can't transfer files. I have MTP checked, and I tried PTP too. I've tried enabling and disabling debugging with no luck still. I'm using the OEM charger for the device, and I have tried using multiple cable with no dice.
"So a new possible way of fixing this after having contacted Asus support. They had me turn of my Nexus 7 and then hold the Volume Up + Power button for 30 seconds and then hold only the power button for 60 seconds. I was told this is to remove static from the mother board. USB Charging, USB Transfer, and Wireless Charging (which is what made me notice the issue) now work. The only problem I have now is that the cord that came with the tablet seems to be a bit loose and will cause it to stop charging when I don't just let it sit on a table."
That was suggested on a different forum, but that didn't work for me neither.
ADB nor fastboot cannot see my device as well.
Any help?
have you tried plugging the cable in to a different usb port?
What drivers are you using? Try the generic USB ones here, which I use with no problem at all: http://developer.android.com/sdk/win-usb.html
For best results, go to Device Manager first, set it to show all hidden devices, then delete (not just disable) any previous drivers you may have installed.
"They had me turn of my Nexus 7 and then hold the Volume Up + Power button for 30 seconds and then hold only the power button for 60 seconds. I was told this is to remove static from the mother board."
I feel like hitting my head against a brick wall when hearing such advice.

Gotta love Asus' tech support.
Try Nexus Root Toolkit, it has a nice walkthrough that shos you how to first uninstall any existing non-working usb drivers. Then just try its options one by one and you'll have working drivers in minutes.
I gave up even trying to get my original N7 and my N7 (2013) to be recognized by any PC. What I do instead is use a free app of the day I got from Amazon a while back called Wifi File Explorer. Run the app and you can access the file system from your PC. Upload, move, copy and create folders.
It's worked for me for a while now. I'm sure there are other free apps that will do the same.

Have you also tried usb ports on the back of the PC? Those are directly on the motherboard, whereas usb ports on the front of a PC are almost always via a usb hub connected to the MB. I know of instances where this makes a substantial difference (device being recongnized or not). You might try it (if you haven't already).
Edit : also try disabling AV software and possibly firewall. But admitedly I have personally never had any issues regarding device not recognized due to this.
This was my solution.
Bought the 'official' usb to usb3 lead from the Play store. When I tried connecting to my Macbook Pro the Android File Transfer can't find the Nexus. I thought it might be the USB Debugging needs enabling so I did that. Nope. Maybe the Android File Transfer needed updating so updated it. No joy. I'm a bit lost now, can anyone shed any light on my problem?
Mine would say something about the screen being locked even though it wasn't.. When you plug it in, pull down the notification drawer and tap the Choose More USB Options, or whatever it says. Make sure File Transfer is selected and try again.. took mine a few times of switching between FTP and Charging but it works with my Mac now

More thanks. I had to switch it between charging and MTP 5 times to get it but it worked in the end.
Is there any way to making the MTP setting sticky for trusted devices? When you connect with usb debugging, it asks you to verify and save the device. If something like that was possible with this setting, you could have the security of not auto enabling when charging from random devices but the convenience when connected to your own remembered computer.
This solved my problem!
