[SOLVED]Computer see's device for a few seconds, then disconnects.

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.

[Q] Connecting to computer =(

When i connect my G2 phone to the computer it use to have a notification to tell me it was connected to a computer and let me turn on usb storage mode. When i plug it in to my computer it does nothing just sits there charging like it was plugged in to a wall charger no option to go to usb drive mode. I am using CryogenMod 6.1.1 any ideas?
I tried 2 different cables and computers...

You might not have the proper drivers installed on your computer.

I don't think its a driver issue because it comes up as a removable disk no matter what computer i am on. It seems like it's on the phones side there is no notification like there used to be. This all started today. was working perfectly before. I have not clue what could of done this I haven't made any drastic changes on my phone or anything.

I don't know what happen i restored it back to another restore point i had it started working again! i don't know how or what happen.

You've probably got usb debugging enabled. Disconnect your phone from the computer, disable usb debugging and then connect it again.

The phone was always on debugging mode, and I still always got the USB connected notification. I think it was an Ap I downloaded that messed with the startup programs. I am not completely sure it is that but was the only major change in my phone since this started happening. So IDK glad its resolved through the restore and backup.

[Q] Cant mount USB, get to DL mode

Hi Guys/Gals
ive done a bit of searching and have tried everything i could think of but still no DL mode, and cant mount USB
I started having a problem with my mic ... thought it might be the ROM so i wiped dalvik, problem was still there. Then did a factory reset, problem still there
Thought i would try a different ROM, but when i went to plug my USB in, my PC would promt me with a USB device not recognized window. I tried mounting USB via USB utilities - No Go. Tried with debugging mode off, still no go.
I have reinstalled the USB drivers, still no go.
The phone also turns on when plugged into wall power, or will not stay shut down ... hrmmm
Im curious if the mic and USB issues are related and it is a hardware malfunction.
Any tips, help, or advice would be GREATLY appreciated right about now.
Thanks XDA!

Welp ... got DL mode on my work PC. Will try to get back to factory and see if that resolves the USB and Mic issues.
Pretty weird considering I tried it a few million times.

Scratch that. Got DL mode, once, can no longer. Wtf is going on.
Holding volume+/- and inserting USB cable. Am I doing something wrong? Its sending me straight to CWM recovery everytime.
Tried to do a restore from a point but got an MD5 sum mismatch

so hold the vol up + down then plug phone

Tried everything.
Not a newb when it comes to getting to DL mode if the phone is opperating normally. (obviously if ive come from CM7, and ICS as an original vibrant owner, and was running a rooted SGS2)
Went ahead and ordered a new phone. Am going to spend the couple bucks on the DL mode USB plug, might be able to save something from the old phone.
Im pretty sure something happened to the phone that affected the ports on the USB and MIC at the same time. But we'll see once i try the plug ...

[Q] Why won't my Galaxy Nexus power on?

I have a Samsung Galaxy Nexus. It is had some water damage in the past (making it near impossible to get repaired under warranty) and that has caused it to act funny. Funny = Powering off at random times and rebooting itself/causing the buttons to act silly. Recently it did the thing where it powered off and now it won't come back on. I know the power button still works and it is charging because when I plug it in the charging symbol pops up when I press the power button. However it won't power on. I plug it in to my laptop and it charges but my laptop does not recognize it is plugged in. Is there any sort of program I can download that will allow me to get into my phone or anything I can do? Also I have tried the Power and Volume buttons to try and power it into Bootloader mode but that does not work either. Neither does pulling the battery or putting a different battery in or using a different charger.

Isnt it clear it is dead? Electric stuff+water=death. (Physics 101)

So your galaxy nexus turned into a Nexus 4? Or is there another reason you're in this forum?

Why are you people so mean? I am looking for help, really just a program that would allow me to plug my dead phone into the computer (since it indicates it is charging) and allows me to get files off of it. That would be nice.

Help

Hey man,
I'm not sure if your gnex is salvageable, but if when you plug it into your laptop it indicates charging perhaps you may be able to get to your data. First question...do you have usb debugging enabled in settings? We have to get your laptop to recognize the phone as a drive,then try to grab the files. Tell me more about what happens when you connect it. We aren't all mean, some here just forget how it was when they had nothing but questions and no answers. Most in the forums are very helpful, regardless of experience level.

Thanks for your civil post, I will try my best to inform you more on what my phone is doing.
When I plug it into the laptop it does indicate it is charging but that is the only sign of life I can get out of it. After reading a little bit more on the issue I figure might be the power button that is the issue since it is running JellyBean. One solution that I have tried that has yielded interesting results is plugging the phone into the laptop via USB without the battery in the phone. My computer then makes the "beeping" sound like it is connecting to it and then "beeps" again like it can't connect.
I can't post a link but if you google katzz ifixit then you can go to the website I went to that described the issue and gave the solution I just described. Katzz is the name of the user who posted the solution.
I'm pretty sure I have USB debugging enabled in the settings because before my phone stopped responding I plugged it into the computer a lot to transfer files.
Is there any sort of program that would allow me to turn on my phone from my computer even though I can't seem to get my computer to recognize my phone?

So you have an idea of why, but not a lot we can do here in regards to HW issues, which this sounds like.
