i searched around and i cant find the thread on this.
i was charging my phone through the USB port and it just randomly disconnected. i reconnected at it is recognized for a second then disconnects. the menu comes up on the screen and i see the notification at the top, but after about 2 seconds it just acts like i unplugged it
i have tried multiple USB ports, cables and different PC's and they all do the same thing now.
i installed HTC sync and rebooted the machine. i changed the power settings on the machine and made sure that the USB power management is disabled.
does any one have any idea whats going on?
Do you have a auto kill app such as taskiller ?

no... the phone was just hard reset. the issue was there prior to the hard reset
it does the same thing on my laptop and desktop
both are windows 7 x46 with HTC sync installed
could be your usb port on your handset OR/AND the usb cable's tip that you insert into the port could be loose/failing. wiggle the usb cord at the end where it connects to the phone GENTLY and see if its loose. should be s snug fit...
I have the same problem n started a few threads about it n havent gotten anywhere. My work computer has no problem seeing my phone but my personal computer will not, very very strange. Ill watch this thread n see if a solutions comes about.
seems like a very snug fit too me...
i should also mention that plugged in to the wall charger it has no problems
i have tried 3 different cables and 3 different computer and all USB ports on those computers, all the same issue
I didn't have this issue till now but suddenly same thing started happening to my phone..
I have plugged in my phone using USB with laptop and it shows me charging but after two minute it just discount it...
me and my buddy have the exact same issue here. what i do is, i unplug it a few times and on the 4th i keep it it. seems to be a bit more stable that way.
i don't think this is an issue with faulty usb ports on everyone's separate computers. (could be but i frelling doubt it) ive tried this in multiple windows machines (win7x64 and xp), and it happened on all of them. Only once did it happen on my work mac. i have not, however, tried a different micro usb > usb cable. i only used the htc one. we could have faulty cables. or it could be a phone issue itself, hardware wise whereas these are the only common denominators we have in this problem that i can see.
i lean towards faulty batch of cables. if you plug in the cable to your phone and computer, and wiggle the middle of the cable without touching the ends, it will disconnect.
what gets me is that there is no problem when it connects to the wall usb port. that is confusing. maybe the cable needs a more heavy flow of power to stay connected, which then leads me to believe that usb drives don't have enough juice to keep the thing going, or at least variable flows of power.
i know the phone has an "issue/feature" where it will stop charging the phone completely when it gets to 100% even if you leave it on the charger. maybe some sort of overcharging fail safe right? so what if there is something wonky going on with the phones usb port, or the phone cuts off the connection thinking your done using it?
its late, im speculating just throwing stuff out there.
I'm getting the same problem. Thing is, if it needed more power, why would it still work in a mac? I didnt have this problem until I went through a few different ROMS. So I dunno. I never had this problem before root. But I dont see any reason why it shouldnt fuction normally

Hi folks,
i purchased a new usb cable today. its retractable, called 'Sync "N" Charge'. it is essentially the same connections as the stock usb connection cable.
the problem is when i try to connect my (Imate Jam) to my PC(winXPpro) it either freezes my pc, or puts up this msg.
USB device not recognised, one of the usb devices has malfunctioned, click here(opens up systems properties).
It does charge the Jam. well atleast the orange charge indicator lights up(i havent checked for actual charge).
The device drivers for my Jam are fine seeing as it still works when i connect with my original cable.
my original cable works fine, even if i switch straight back to it after trying to connect with the new cable.
I think the cable may be wired incorrectly eg postive and neg prolly fine but the data pins are screwie some how, sound like a reasonable guess?
Is there something else that im not thinking of/dont know about that could be causing the problem?.
bleh just typed all that and answered my own question. the data pins in the new plug are a little bit shorter than the power plug. I use a silicone case on my Jam which stops the plug from pushing in all the way by like 0.25mm. took off the case and bingo problem fixed.
I hate when that happens.
Ok well i might as well say that its a nifty little piece of hardware now that i got it working.
Which leads me another question, the reason i got this new cable was to be able to leave it in my bag and pull it out when i wanted to use my Jam like a 1gb usb card(1gb sd card). the times when i wanted to do this would be at university.
is there a way to make a pc recognise the jam like a usb drive instead of a pocketpc upon connection? i wont beable to install activesync on university pc's.
Thanks

Well suddenly I couldn't charge my device, I switched chargers, switched the cables, tried connecting to the PC (with different cables) my old VOX does fine with all the connections too... so I guess something broke internally.
Don't suppose anyone else has had these problems?
Check out the option..
... under settings... power, there is an option to not charge device when connected to a pc while power is on. I cant begin to imagine why its there, but it is, and it causes the symptoms u describe...

Sometimes my phone will not charge when connected to the wall or my computer. The problem usually goes away on it's own, but when I need to charge I generally need to charge.
Sometimes I cannot access my phone via USB on PC either.
Only with data to and from the computer. No charging issues at all.
I've never had issues when plugged in to computer (USB). I frequently have issues when plugging into wall charger, but I think I have a bad cable. Phone will recognize charger connect, sit for a second, and lose the connection. Charging stops while cable is in. I bought a cheap cable on-line for the wall charger. I guess you get what you pay for....!
I have issues with usb connnect to computer since flashing cm6 8/13 nightly. Will not charge or mount usb.
Restoring back to 8/11 seems to fix issue but can't seem to get any newer nightlys to work or rc2.

Kind of sounds like a loose connector. I bought some micro USB cables from monoprice and the size of the connector was just a tad smaller than the plug for the phone. So if the cable wasn't plugged in and propped up in a certain way, the phone wouldn't charge. I just bought some new cables from monoprice (the ferite core ones) and problem solved.
I guess when this happens to you, wiggle the cable a little and then hold it for a few seconds at a certain angle and see if it starts charging... if it does then you know you need a new cable.
I was having similar issues and with my sd card permission issues I simply uninstalled my usb drivers and my removable disc drivers for the phone on the computer I think there was like 3 sets and haven't had an issue since.
Just got a brand new Samsung Galaxy SII T989 from T-Mobile this week, it really is a great phone, only I have a single problem.
The phone charges, it functions properly generally speaking (calls, texts, camera, wi-fi,etc...) but as soon as I connect it to my computer it freaks out.
It acts as if I were disconnecting and reconnecting the USB cable 2 times a second. I can hear the phone making the beeping sound it makes once you connect it to the USB every few seconds and in my computer (Which is running Windows 8 x64, just in case.) I can see the "Safely remove hardware symbol pop up and disappear a few times a second as well.
This is really frustrating... I love to take pictures and videos and edit them... I'd also love to copy some music over as well...
So far I've determined it can be the cable, bad drivers, or the phone itself, I just hope it's one of the first two.

Try re installing the correct drivers or switching the usb hub. If that does not work it's most likely the usb cable, swap it for a different one and you should be fine considering you bought the phone new.
Or you got a phone with a bad motherboard which would be crazy considering its new but that kinda sounds like the problem I had

Alright cool, but how does one find currently installed drivers when the device isn't plugged in?

Ok, does it get better or worse if you hold the cable with your finger when it is plugged in to the computer and phone and move it around a bit on the phone end? If so, I even got a Nexus 7 brand new from Google that the charge cable phone end was bad and would not make a good connect and I had to use a different cable and it works fine with my tablet.
If you use the same cable in your AC charger and on the computer then prolly not the cable.
It could be something in Win8 if it is trying to scan your USB port [like maybe a whacked anti-virus].
Have you tried a different USB port on your computer to see if maybe the one you were trying to use is bad itself?
If using a USB hub between your computer and the phone try removing the hub from the equation and connect directly to the computers USB port.

I am using a HUB on a Razer Keyboard that I've always used BUT now that you mention it my webcam had the same problem. It wouldn't work with the HUB on the keyboard. I'll try another USB slot (My computer's other USB slots aren't very accessible which is why I've hesitated to try another slot.)
I don't use anti-virus and yes, the cable works perfectly fine on the AC USB to Power adapter it brings.

I love you. It worked. It's the USB hub which doesn't allow much power to go through to the connected device. Thank yo so much.
So I have a SGH-I747M... recently came into my possession, existed for not sure how long. In any case, I'd love to just jump in and explore what genius this forum has to offer, but I've run into one small tiny problem - my phone isn't getting detected by my computer when plugged in.
It charges, but it doesn't get detected as a device.
Things I've tried:
USB Debugging (on and off)
3 different USB cables
Every single port available on my PC chassis, including the ones that are connected directly to the mobo
Uninstalling and reinstalling the drivers for the S3 from Samsung's site
Pulling the battery
Resetting the battery
Restarting phone
Restarting computer
Connecting during Download Mode
Towelroot (it says for all three options "this device is not supported")
Setting through *#0808# MTP and MTP+ADB
Trying a different computer
The cables I've used are all five pin, so its not something as simple as "oh haha im using the cable that doesn't have a data pin"
To be clear, nothing has appeared in Device Manager, and nothing pops up in Computer when I plug it in.
Anything I might be missing? I'm sorry if I've sounded rash or rude in this post, I've spent the last two days trying to diagnose this problem.
It's possible the USB port is defective.
Did you try another computer?
It might be possible that the port is defective, I assume the device charges if so then try a otg item see if the phone sees it
