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.

I can confirm this works on my HTC Desire - had been racking up my brains for the past couple of days now with no solution! Thanks a lot. This is on PC with Win7 Ultimate.
I'm sorry, I hate when people ask questions in the wrong section, but I literally have 2 hours to sort this out.
I dropped my phone and the screen won't turn on and doesn't respond to touch.
The insurance company is picking it up first thing tomorrow (*hence the urgency) and would like to get some stuff off it. Most stuff is on my exsd, so I'm not too worried if I have to wipe it, but would prefer only to wipe it once everything is off.
I'm rooted and have a custom stock based rom and cwm installed.
Is there any way of doing this? I have the lock pattern enabled so when I plug it in nothing shows up.
If not, then how would I wipe it?
It's omega rom btw, so it has cwm touch. Would the volume buttons still work with it?
It's probably too late but you should set up your device with Samsung "Find my Mobile" (ex-Dive) as soon as you get it. That way you can remote wipe it as long as it's receiving a Wi-Fi or cellular signal. There also Mobizen which allows you to control your device from your PC. It auto-connects so you'd be able to use it without a working display but you'd have to make entries on your device the first time you set it up. You might try plugging it in to a PC and seeing if it'll let Kies connect with the display locked. You could at least manipulate your files. Other than that I don't have anything else to suggest.
Tried Galaxy Note Toolkit? Pretty sure it has a option to backup the phone over USB after booting into recovery. Can't be certain you don't need to press a button on screen, but if memory serves it's all automated.

Seems I was signed up for dive and was able to remotely wipe. Thank you!
good morning, friends
I tell them I am death, I would just drop my LG OG from the bed to the floor and hit in the upper right corner breaking the touch screen shutting down. The help I need is this, I need to go to the internal memory of the phone but the conditions that I have are the following:
- This lock, which can not get out, to be the bad touch
- I have not activated the debug mode, and I can NOT turn unable to use the touch
- I'm not ROOT
- I have not unlocked the bootloader
- I did not I connect the mouse and it does not support the ogm
- I can not install a APP remote control from the pc since I is blocked cell
hahaha now that I see all the unfavorable conditions somewhat impossible to see, someone who will enlighten and help me please.
thank you very much.
PS: I do not speak English jajaja
in such situations, i really dont like to help but try hardreset (theres an combination)
Why would it serve the hard reset in this case?

When you plug your phone into a PC via a USB cable, it might be recognized as an MTP device, depending on your PC connection settings. You don't need USB debugging for that. So, if you are lucky, and you phone was configured to connect as an MTP device by default (and not as charge-only, for example), you should get access to your internal storage. Does anything happen when you hook it up to a PC?
phone folder appears, but when I opened, there is nothing
Ok, first off I chose Sprint because I believe that Boost Mobile is on the sprint network, but my phone doesn't specifically say sprint on it or anything, so I had no clue which of these device boards to post into. This is the exact page I got it on, if that helps. [link deleted - paranoid forum rules] - I will post specs of the device in a minute.
Alright, the issue with my phone, is that after I used a car charger 2 months after I got my phone, it suddenly stopped being able to connect to ANY computer ever again. I suspected it was PDA net at first cause that was the newest change I had done to my phone. So, a few days later, I could find now way whatsoever to fix it, and had to factory reset. This fixed my phone just fine.
Two months later, I was fed up with having battery issues all the time, this phone drains battery faster than my laptop, and its battery is 3.8 years old! I got an external battery that holds 20,000 mAh/74 Wh (Practically the same as my laptop battery too. ) that is from the LimeFuel company. I know that before I used it, my phone worked with my laptop just fine. I don't plug my phone in to my laptop all that often, especially now that I have a battery to use with it. However, I download large files on my phone with 4G to put onto my laptop because my home net is crappy, so a week after, I noticed that my phone lost the ability to communicate with computers, again. I then realized, it had to be the connections. The first time it happened was when I used a car charger, the second time, an external battery. Each time, my phone suddenly inexplicably lost the ability to communicate with a computer ever again. It can only see devices as a power source, nothing more. There's no missing software or drivers, it just doesn't register as anything to my computer. Like a power toggle so it can't tell the computer "Hey, I'm a device that you can transfer data with".
One more note; The first time this happened, I had activated developer options but had them turned off. I mean that I used USB Debugging mode once and turned all of that off. The second time, I hadn't even unhid the option yet, unhid after my phone broke again to try and fix but nope.
I did research on trying to fix it, without factory reset because a factory reset is USELESS, if it's going to happen every single time I use anything but the wall to charge it, right?
There was a topic online claiming that there is a menu under "Storage" in the settings. There isn't. It was a big fat lie. Or Android devs deleted it.
There was another topic, claiming that USB settings would be under some wireless and networks area. Nope.
Now, I remember that when my device would connect to the computer, it would let me change it from MTP to PTP, but after this happened, nothing. It doesn't even pop up anymore, nor does it ask. There is no where in the phone that these options even exist at all. It's like Android devs deleted access to these options for no reason whatsoever.
Another bit in that topic mentioned ‘USB Mass Storage’, which also doesn't exist. Here's the topic with everything I tried, if I'm allowed to give links at all. If not, well not my fault. Topics used to try and diagnose and fix issues, but failed;

First off, after the factory reset and everything worked did you reinstall the pdanet?
Second, 20,000mah battery? Holy cow im jealous!
Forgive me if you have already tried these things but this is what i would do...
Did you reenable developer options and reenable adb debugging?
Did you uninstall and reinstall your phone drivers?
Is there an updated phone driver?
Have you tried a different usb cord?
Is there excess dirt or dust in usb charge port on your phone?
Does your usb charge port even work anymore or do you just charge external battery on wall?
Have you tried a different usb port on the computer?
Have you tried on another computer?
Have you tried updating computer drivers?
Have you enabled a fast charge tweak like on a kernel tweak app?
If none of these questions fix it then a workaround is downloading app called airdroid. You can wirelessly transfer files from phone to computer and back again without usb cord.
Let me know what worked please! Good luck!

1. No, I never touched PDA net again.
2. Too bad forum rules say I can't be friendly and give you the link to it.
3. Read the topic you quoted. I did, only after my phone broke again. Except it's not adb debugging, it's USB debugging. Doesn't work, because the phone can't communicate with a computer anymore.
4. 5. 11. Yes I reinstalled drivers and no there were no updates.
6. 7. Nothing's wrong with the cable. I did try with others.
8. What does that even mean? Yes my phone's port works. Nothing's wrong with any hardware.
9. 10. I've tried different ports and different computers.
12. Can't, phone isn't rooted.
13. I'm not using this. My phone is not there for Google/Android to tell me I'm not allowed to use my USB port ever again. I'm also not going to wait 4 hours for a 4 GB file to transfer via my router to my computer nor am I installing some app software to my computer just to have wireless transfer. This is not a work around. This is an "Oh well, it's broken, guess you can't ever use USB ports again for data access!"
note; I tried all of these (except 12/13) before I ever came here looking for help.
2. I will google it
3. I didnt realize toggle to turn on usb debugging didnt work sorry. I just know it needs to be on for the computer to see the phone. This seems to be an area of problem possibly.
8. Lol! What i meant was did the area where u insert charger function properly. Only reason i asked is because some of those batteries charge on wall unit made specifically to charge the battery only not with charge.
12. Doesnt require root for basic settings like changing governor usually. Only to overclock/undervolt, etc.
13. Great answer! But i meant as a temporary fix until someone more experienced with this issue helps you.
I also figured listing all those things would help other people see what you had and hadnt tried before asking you next time. Wish i couldve helped more. Good luck

2. amazon dot com /External-20000mAh-Limefuel-LP200X-Flashlight/dp/B00OHZVN5U/ - It let me charge my phone 7-8 times fully before it was empty. Automatically stops when your phone is full.
3. USB debugging doesn't need to be on in order for a phone to communicate with a computer. This is only if you want to debug apps or use other developer tools. File transfer works just fine without it.
8. I still don't understand what you mean. My phone is not broken in any way. Nor is my battery. My external battery charges off any USB input, my phone charges off any USB input. My phone just can't communicate data wise between devices anymore via USB.
12. Fast charge isn't going to fix my phone. Unless it disables data communication, then I need to turn it off. All "kernal tweak apps" appear to require root. The top 5 google searches shown this.
3. Wasnt sure. Ive always had it on
8. Some aftermarket batteries dont charge while in phone hooked up to charger. They come out of phone and into specialized charger for battery only not phone with it, so that it can charge the larger battery in a matter ofan hour or so is what i have been trying to say. But its obvious thats not the case for you now since i asked and clarified. If this was the case one might not know that the small usb port on their phone needed cleaning to make a good connection because they literally dont use it to charge their phone. They charge their phone with external battery charger. You see?
12. On my custom rom and on my trickstermod app it does say fast charge disables data communication and that you have to turn it off for computer to recognize phone again. This fast charge mode only works when connected to computer not wall charger it says
Wish i could be more help but im out of ideas. Good luck
Update to the current situation.
My phone is somehow, repaired. But I have no clue why. I did several things today, just screwing around while I backed up my stuff to the SD card. One of them could have fixed it, or my phone is magic and self repairs after a while. Lets list everything I can remember that I did.
1. I typed in *#9900# in my dialing app. Toggled an option called "Low battery dump" to "on".
2. I deleted a whole bunch of files, including hidden files on the internal storage. Probably screwed up my apps but, whatever, it works now.
3. I pulled the SD card out.
Shortly after all these things, I plugged it in for power, and it finally, got my computer to see it as an MTP device again. No clue which of these succeeded. I'm going to wait a small bit before I test the things that tend to break it.
The magic option, is because I tried to root, it broke, stuck in download mode with some error about firmware. For 4 hours it was stuck like this, I tried everything I could think of, which wasn't much, tried installing the ROM back too, after wasting 2 gigs of bandwidth downloading it only to get an error before it even started the install. Phone was still rebooting in download mode error screen. Left it sit there off for like a minute and it just turns it's self back on, flickers a few times and the logo pops up and the device pops on like nothing had ever happened to it. I'm so confused. :/ At least everything's back to normal. Now add a good confusion post icon below so I can click it and post. :|

Except, I don't have a fast charge option anywhere. I can't toggle fast charge. My phone is unrooted and locked and such. If plugging in a device like a battery or a car charger, toggles this option and the OS developers deleted access to toggle this option, it is an OS bug and a critical issue in the device that needs to be fixed. I don't know what fixed it, but I'm assuming it was the low battery dump, and that doesn't appear to have anything to do with fast charge and it was a hidden secret option in the system.

The way u said it i misunderstood i thought u did have it on. Its not an option on all roms though. Mine has it and i tried it and couldnt see files thru usb until i toggled it off so it was just an idea. I dont know the effects of the low battery dump off top of my head but i will remember that if i hear someone else with same problem. Glad its fixed now
The touchscreen on my 2013N7 fizzled out earlier. Responsiveness has been on and off for the day - for a few hours it would improve after I press on a certain spot on the back of the device, but after that it has gone entirely. I've rebooted several times and there is no response.
I'm trying to use android control (http://forum.xda-developers.com/showthread.php?t=2786395) to just access it and get my data off of it, but when I plug it into a PC, the PC doesn't recognize that there is a device plugged in at all, even though it'll still charge the N7. It's completely missing from the device management list; adb shell can't find devices plugged in. I've looked around for possible fixes, but all of the ones mentioned require being able to access the tablet.
I'm at a bit of a loss here - is there a way to get the N7 to show up on the device list, or an alternate way to pull data off of it?

The spot corresponds to the plug (att) and now it is time to unlock, reseat the cable and relock it as all of the problems relate to poor contact of the cable.
Same issue here,I am inserting a usb otg and connecting mouse there and then rebooting. This is really a bad issue
