Develop Bugs

[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.

This will sound odd... but shut down your computer and then UNPLUG it for at least 30 seconds
I bet it works when you bring it back up.

Newb with USB issues

Hello all. I'm TK, newb who has been lurking for a while. The forum has led me to some awesome changes with my Evo, but that may be catching up with me. I'm still rooted and running CM 7 with SZ 1.01, and none of my computers are able to recognize the USB drive on my phone, regardless of which cable I use.
I can't get ADB to work on my PC, so I'm not able to perform any commands for the phone.
Can anyone help me with this issue? It would be much appreciated. Thanks!

Do you have debugging(in application settings) on when trying to use adb? What about allow mock locations? Try turning debugging off and then turn it back on(while plugged in USB). If that doesn't work you could always go to recovery mode and enable USB toggle and get it connected that way. Also make sure you're actually pulling down the notification bar and selecting "mount".

Does your phone get recognized at all on your computer when you plug it in? If not you may have a hardware problem -> usb port is loose.

On my original cord that came with the phone I had to trim off about 2 centimeters off of the plastic to go in far enough to have my Toshiba laptop to read it. I have had to do the same thing to several cords since. Maybe your usb?

Yes, my computer just says that it doesn't recognize the hardware. it charges just fine by the computer.
I'm running ClockworkMod for my recovery, I'll check for USB Toggle there.

No joy on finding USB Toggle.

It's called something different. Can't remember but it's there, I believe. I've only been in Clockwork recovery like once.

i think my phone is defected cant transfer files on my computer

I rooted my phone and have it with the latest calkulin rom.. the problem is wen i connected to my computer my phone still thinks its charging. and i have no option to turn on the usb mass storage.?? so i dont know if my phone is defected or is it a rom. issue..yet i already tried 2 roms flashing them fresh.. but nothing seems to fix the problem...does any one have any idea what causes this???

settings>wireless and network>usb utilities
With the phone unplugged from the usb click the connect button then connect the usb. You should recognize the standard usb screen at this point.

Some cables (notably most LG branded... But there are others) just don't work... Damned if I know why.

I would flash it back to stock if you already played with different cables and fixed your settings. Getting it exchanged should be easy if your still having the problem on stock.

connect to pc?

when i plug it in it charges only?but nothing appears on my pc??

try a different usb cable mine did that i was using a different usb and then it stoped working so now i just use the one that came with the phone and it works

i tried..odd..
i think it stated when i activated power saving mode..
im testing now,..

ok so i shut off power saving mode rebooted my device and bingo..odd ah...

I restart my computer when that happens. For me I believe the issue is caused by plugging multiple phones into my pc to load files. This assumption is because I never had this trouble until I started loading apps on my girlfriends bionic as well as my hercules. I am using the cable that came with my g2. My hercules didn't come with cables.
Another fix is WiFi File Explorer. What I like about this fix is that it saves wear and tear on the micro usb jack.

true i will try that.thx
