[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] PC can't seem to detect Kindle Fire?

When I plug in my Kindle Fire to my PC, nothing happens. Why is this?
The Fire charges its battery when plugged in to the PC but no notification whatsoever that says it's connected. Windows explorer doesn't show up and I can't find it in My Computer either. Using XP by the way.
Also, may or may not be related to the problem but, when I charge my Kindle Fire it stops charging when I use it, but when I put it on sleep mode it resumes charging. Can I not use the Fire when I'm charging anymore? I used to be able to do it but for some reason I just can't anymore. Is it broken?
But in all honesty I'm not really bothered by the charging problem that much. What I'm more concerned with is the fact that I can no longer transfer files to my Kindle Fire from my PC. How do I fix this?
Please help!

I am sorry but what is this "debugging"? I'm a total newbie and I have no idea what that is.
Edit. Actually, I haven't done anything to my Kindle as of yet because this is the first time a problem has occurred.
No unbricking, debugging, etc etc (any of those technical terms).

So you are running at 100% stock and not rooted? What software version is your device running currently?

I don't know how to find which software version I'm using but my Kindle Fire's system version is 6.3.2_user_4110520. First generation if I'm not mistaken.

Well, the first generation Kindle Fires enable USB mass storage automatically when the device is plugged in, and considering you haven't made any modifications to the device whatsoever, one has to assume the problem is either with your computer or the device's USB port. The USB ports for the first generation devices have always had a problem with coming loose, so you might want to see if finagling the plug will make any difference.
Unfortunately, the charging problem you mentioned earlier causes me to think that the latter is most likely the case.

I was afraid it would be this. *sigh*
Which would cost me less, though. To buy a new one or to have it repaired?

So I know if you plug a computer with an A to A cable it stays in the bootloader to allow you to use fastboot. I wonder if it sees something plugged in and just is like "oh well" and stays in the bootloader.

that makes sense, because it will stay in the amazon logo (not animated) and will not move to the animated amazon fire tv logo. wish i could stop that tho

If it's staying on the white logo, then it is definitely in fastboot. I haven't messed with it much, but I did notice once that the Fire TV was being powered by the USB port, which caused boot issues. It's possible that getting power through the USB port is enough to put it in fastboot. Perhaps your harddrive or hub is sending power to the Fire TV, causing fastboot to kick in.

im guessing so, its a 1tb usb 3.0 drive which im using one of those Y cables to give it power from a usb outlet otherwise it will just click from lack of power.

Ah, there you go. It's the Y cable that's causing your issue. If you used a powered USB hub you probably won't have this issue.

Hmm i see, i will try the powered hub. Thanks for the input. Will respond back when i get it and post rwsults

I also have this issue. I have a powered usb hub with 10 ports. I use it to plug in my HD and RF remote and RF keyboard. It will not reboot. It just stays stuck on the white amazon logo. I thought It was stuck in boot loop. Now I know the powered usb hub is the problem. I unplugged it and now FTV boots as normal. So I guess we can't have powered usb hubs?

powered hubs and non-powered hubs worked for me with usb flash sticks and 2.4Ghz keyboard. Never tried a HD.

This happens to me when using a Powered USB Hub, it will not boot and stick to the first Amazon Logo.
When I'm using the same USB Hub with no power cable plugged it, it boots successfully.

As far as I remember, the first time I have plugged it powered it had nothing connected to it.
But I might be mistaken and It had a 2gb usb connected to it...

Fire TV USB devices not recognized

I've been using my Fire TV with a Logitech wireless keyboard\mouse combo device and just recently i've noticed the fire TV isn't recognizing that anything is plugged into the USB port.
How do I fix it?

I run into this issue on occasion and have found that disconnecting and reconnecting the Fire TV power cord from the wall outlet solves it for me.

Are you using a hub? If so try going directly into USB port or different hub. Is it just the keyboard or is nothing getting recognized?

nope, no hub.
but I just happened to grab the keyboard I was using and turning it on to see if it would work, didn't need to use it, just happened to try and test it, and it worked. I didn't do anything.
so I figured it was maybe the batteries (even though I had tried plugging in a flash drive when I was originally trying to diagnose and fix the issue) and put it on the charger (it's a rechargeable wireless keyboard\mousepad.)
so I don't know what was causing it, but last I checked it was working

Thanks, worked a treat.

USB problem

Hello, I have problem with USB connection.
When the phone is connected to the computer, the phone starts charging but the notification of the choice of file transfer, charging, etc. does not pop up. The computer pops up message that the device is not working properly.
In fastboot mode, the same message pops up and you can hear the repeated sound of the connected device until the phone is restarted.
The headphones on the adapter and OTG do not work either.
I tried different cables so it's probably not that, I also replaced the bottom board with a USB port but also no effects.
Could this be due to damage on the motherboard? How could I change rom without usb? I have uploaded MIUI alpha 8.5.31

You can try edl mode and if that doesn't work too that maybe a hardware problem

Hey. I read about such problems on one of the Polish forums, and from what I know helped to clear the usb socket on the phone. Maybe it's stupid and will not help but it's worth trying

I think if I do a hard reset, maybe the phone reinstall the drivers knowing the new usb board.
