Hello
I'm having some USB problems:
The device seems to disconnect after a few minutes, sooner with intense usb activity (like copying files)
I tried with 2 cables, 3 computers and with both XP and linux
However 3 days ago it didn't seem to act like this, altough at the time I didn't use the device so much (I was busy exporting/importing the contacts into HTC)
I tried hard reset, didn't work
I can only think of 2 possibilities: either there is a problem with the usb driver in the device, ori there is some problem with the electrical connection somewhere on the device
So, the question is - does anyone else experience the same problem?
Thanks
I think, that device disconnects when it goes to sleep mode (my device does it). When it is on USB, it acts like it it on charger, so simply make charger sleep time longer. It is quite annoying, but only solution so far.
No, it's not that, my device doesn't go to sleep when connected to a power source, anyway I tried to disable sleep mode completely and it still gets disconnected.
Interesting, the device still belives it's connected (I see the icon at the top of the screen), but the PC end is down.
Never had such issue. Maybe you could try to contact HTC Tech Support... But as the hard reset didn't help, I'm sorry to say, maybe you should consider a warranty claim. Might be a bad connector or something.
Ups sorry, i didn't read correctly the original post.
Maybe, it´s will be the energy-management from PC?
Look in device-manager in the properties of the USB-Port, try to disable the "Energy management". Please post the result here.
Greetings Mirko
Tried that too. Same result
Hello 4EST,
please use only the origional USB cable to connect PC and XDA! You got to pull the Mini USB side as you can´t see the silver part!!!
The connetion lost when you act at the cable?
Somethimes it seems only to be connectet right.
Greetings
Rescue01, I used the original cable, the problem is exactly the same.
Here is an update:
I sent the device for reparis to HTC. The device came back "reflashed", but the problem still pesisted from the first power-up. In other words, they fixed nothing, didn't even bother to check if it worked right
I sent the device back again for repairs, very angry, talking to the call center. This time they opened the device (I can see it on the screws), did something to it, then reflashed the device again.
And it worked perfectly, with all the cables and the computers I tested before........for a while....... Because after ~4-5 days of usage the problem started to reappear more and more.
Now, as I just tested, the USB gets disconnected after only 5sec of reading from the device. Sometimes it lasts longer, like 2 min
So my opinion is that there is an electric problem, I would guess with the USB connector
Unfortunately for me, the service center even if they fixed the problem last time, they did NOT checked for it before fixing it and assumed everything was ok the first time and blaimed the USB cables/computers for the problem. They said something like "sadly, after checking the electrical connections and reflashing, the device works perfectly". And it did for a few days...
Here is an update:
I send the device for the 2nd time to the service center, this time calling them angry about not fixing it for the 1st time.
The device came back quickly. This time they opened the device (I can see it on the screws), and the USB connection actually WORKED!..........for a while.....
After 3-4 days it started disconnecting again, having less and less USB connection time.
Now I have to try to get it conencted, as sometimes it disconnects right after connecting

The first thing I tried to do when getting my Vibrant 2 days ago was to try to install drivers, wasting hours and hours and getting nowhere (all I wanted to do was to copy the rooting zip to root the phone). Yesterday, I tried turning off my USB Debugging, and then mounted the SD Card(s), and they both worked as they should. Great, so I can get my computer (Windows 7 32bit, FYI) to recognize the drives and copy files (by then, I had already just copied the file I needed to via just taking the SD card out, phone has already been rooted, but now I was thinking about tethering).
So today, after having done a lot of searching the past 2 days, and having come across a post I found on another forum (sorry, I'll have to go do more searching to find it again) where someone suggested that one of the issues might be the USB plug on the computer not being a powered one (this was front USB port on a Gateway computer), I plugged the cord into a powered USB hub I have, turned USB Debugging back on, plugged the phone in, and the driver install went a bit further than it did before, at least recognizing the device, but not installing the drivers. I went into device manager on my computer, pointed the 2 unknown devices to where the Samsung Drivers I downloaded off of Samsung's website were and everything installed perfectly. Phone is now recognized when plugged in, and the SD Card(s) mount just fine.
Since that was a major reason to keep/return the phone, I'm happy to have discovered the solution to 2 days of research. I thought I'd share this in case anyone else might be having issues with installing drivers for the phone.
Now to see about the battery drain and some other potentially "minor" issues and see about it really becoming a keeper (coming from a MT3G, it is a major upgrade, so it's just getting used to the differences).
I had an issue with USB Debugging on too.... so I thought, then I realized I was using the Nexus One cable and not the Vibrant cable. I turned off USB debugging and used the proper cable and everything was automatic.
Interesting read, thanks for the post. Perhaps I need to tweak the sticky some.
edit: added this thread to the sticky. Thanks man.
Interesting note about the different cable options, I had read that some cables were "better than others" - I had to use the micro USB cable that came with the Vibrant, so I knew that wasn't an issue, figured I'd tried everything else, so what the heck (thought I swapped the USB plug last night, but turned out I swapped the wrong cable, lol).
I did order a bunch of generic micro USB cables from ebay (2 different sellers), but I just need those for charging (like for the car, for my travel back, etc), I'll stick to the Samsung cable for data needs and likely test the others in case I need a backup.
Your main thread was definitely helpful, and I just wanted to share a potential solution to an issue I had seen others post about without any resolution (actually, the person in the other thread had a slightly different problem than me, and never claimed solving it by changing to a powered USB plug).
Hello
I've got an HTC HD2 tmo US...
When I plug in the sync cable from the phone to the PC, simply nothing happens.
The phone charges but Mobile Device Center shows not connecting and nothing about detecting hardware or anything, when I set the phone to ask what to do (ie. Disk Drive or Activesync) It also doesn't ask anything when plugging in.
Any ideas?
First check the phone with another cable. Are you using the supplied USB to micro or another cable - like a retractable? I made the mistake of buying a retractable that wasn't fully wired to handle data.
Uninstall Activesync and reinstall with the phone disconnected - they once the install is done reattach.

Hey
Yup, I tried another cable, both are official HD2 cables or OEM...
I have also tried another PC (32bit WinXP) - still no detection.
When I press volume down and power for 3 seconds, it gives me that tricolor dislay, i tap it and changes to USB, my PC then sees the phone (but of course not usable).
So I think it's software related, I'm trying to flash with the SD card, but so far it's just stuck on Loading....
Any other suggestion you might have perhaps?
I've managed to figure out it seems to go into car kit mode everytime I plug in the sync cable, and NaviPanel pops up some times. Looks like it's a tad buggy though cause it won't go away and then it goes away and comes back, etc.
Any ideas?
stuck in car kit mode is indicative of a faulty usb port. some people have had success by cleaning out the port with various means,,, compressed air, wd40, toothbrush, one aguy even spat in it.
mostly, though, it requires a warranty repair.
theres a thread "stuck in car kit mode" in the regular hd2 general section.
That fixed the issue! Toothbrush, yes I failed a few times, just kept watching the screen and got really in there hard and dirty on the top small gap, and wala- the light came on while it was locked and it worked.
Is this a permenant solution though? Is it really only dirt and something that is just for maintenance sake or should I be worried the hardware is faulty or on its way out?
Sorry, couldnt say. Sent mine away for repair and they swapped out teh whole board. Plus minewas deffinately clean as a whistle. It seems some people have dirty slots, some have hardware faults.
Have you tried messing with the USB to PC settings?
Settings > Menu > All Settings > Connections > USB to PC > Either pick Activesync or Disk Drive.
Sometimes my computer doesn't do anything when I plug in my phone using Activesync. I would have to open up Windws Mobile Device Center and detect it manually.
If you are having problems getting to download mode, Use the Stock Captivate Cable Only when trying to access Download mode!
Story:
I have struggled with 2 captivates now to get into download mode. I have read tons of arguments back and forth from people that say it is easy to get into download mode, and people who say that it is impossible with their phones.
Well, for some history...On my first captivate, I bricked it and it refused to go into download mode...PERIOD. I proceeded to exchange it(I was within my 30 days), and didn't think much more about it. Well, I installed Cognition 2.2 recently and in the process realized that my new phone would go into download mode just fine by doing the standard process of:
1)remove battery, sim, microsim
2)reinserting battery only
3)holding down both volume buttons
4)inserting usb cable
No problems right? Well, I ended up "bricking" my phone by accidentally deleting my framework-res.apk file(don't ask) and lo and behold, I suddenly could not get it to go back into download mode. I was really pissed at this point and spent all night trying everything all over again.
Well, I decided to give up for the night and go to bed. As I was laying in bed a thought crossed my mind. I had purchased a second usb cable(from ATT) to use with the captivate, and the one time that download mode had worked, I was using the standard captivate cable that came in the box. However, every time it wasn't working I was using my second USB cable. So I got up out of bed to try the stock cable and, lo and behold, it works flawlessly every time.
I would venture to guess that this is what the problem is with most everyone else that can not get their captivates to go into download mode. So, if you haven't tried it give it a shot. And certainly tell everyone you know to use the stock cable only.
I just want to reiterate that the spare cable that would NOT work was purchased from ATT and is the cable that they recommend you purchase as a spare. It wasn't like I got it from ebay or something.
Using a usb cable I got from ebay, monoprice, htc, motorola, and stock samsung cable, I was able to get into download mode everytime...
... also, shouldn't this be in general and not in development?
No USB Hubs or Extenders
RECOMMENDED: Use your stock USB cable that came with the phone.
IMPORTANT: Plug the USB cable into your computers native motherboard USB port (the back of your computer). Plugging the cable into USB switches, extenders or external ports, does not allow the phone to enter download mode correctly.

I can confirm, although i found this out a whilllllle ago, just didnt think much of it lol
Just so you know. I found that in some cases certain USB cables just will not work with some devices. This has to do with the quality of the cable. I would avoid overly thin or flat cables because they tend to be cheaply made and won't be able to provide a stable power flow. The shorter the cable the better.

The cable he/I bought from AT&T is shorter the the cable that comes in the box, and doesnt work, so im not sure if shorter is better

I can recreate this over and over again. The reason I put this here and not in general is because I, like many others, have struggled over and over with odin, and people had the attitude of "it works every time, you're just doing something wrong." The reality is that you're trying to prove that I'm just "doing something wrong" because all your cables work. I can recreate this over and over again. What do you want me to do, make a video of it in order for you to believe that there is an actual issue?
I think it's important for people to see this when trying all the roms and mods that are in the development section. In fact, I think it would be REALLY helpful if designgears would add this to the "how to get to download mode" section on the Odin thread. I can't tell you the amount of hours I have spent trying to get into download mode. It is incredibly frustrating to do everything right, and have others telling you that you are not doing it right.
I searched google endlessly looking for a solution to get into download mode, and no where did I see this as a possible solution. Also, as an FYI, when I plug in the other cable, it just goes straight to the battery screen no matter what I press. I can hold down the power and volume buttons to go into recovery mode, but it's impossible to get to download mode.
I have plugged mine into a usb port in the front of my computer as well as in my monitor. I have never had a problem with download mode or anything else.

While this is good to know...It is quite possible you got a faulty second cable, and some of the cables that do come in the box are faulty as well..
It's always a good reminder to try changing out cables if your having an issues. Same for downloading different things that work for a-lot of people and not for you/me..same too for hooking into the back of the computer and bypassing the external hub....Sometimes you get lucky and find the problem right away..sometimes you don't....It's called a process of elimination...
FWIW..I've never trusted cheap ass cables..in anything. Never have..Never will..but..JSYK..expensive cables go bad from time to time too
Thanks for the reminder

I've also noticed that, on my PC at least, my front case USB ports don't always reliably work with this procedure. I've been plugging the USB cable since into the USB ports on the motherboard.

The thing that throws me off is that this cable works for EVERYTHING else. Data transfer, media syncing, recovery mode, charging, etc... There was never anything that would indicate any issue with the cable. I just want to make sure everyone knows this, because when I was struggling to get into download mode, I didn't see anyone suggest that it could be the cable, even though the cable worked for everything else.
OP - thanks for posting this! It is at least another thing to keep in mind when troubleshooting. I was actually considering getting another cable to keep at work.....
P.S. would we get in trouble for quoting Michael Scott's favorite joke in response to post #6? Yea, I know. Little too obvious right. I'll restrain. Already made myself chuckle anyways

Um.. not true - Although I did use the stock USB Cable - I was flashing the night away (trying to recover my bricked phone) on my Win7 box using a USB hub that had a few other devices hooked into it.
Never had an issue getting to D/L mode.. and it found the phone again and again and again and again.... (go on for infinity).
I think it has more to do with the hardware your connecting it to and how the USB drivers loaded (i.e. XP=****e) and what type of OS your running more than anything. I had terrible luck with my work's XP rig... but my Win7 x64 rig found the device while in d/l mode - found the drivers?!?! and I was good to go.
Although - it is always a good rule of thumb IF you can't get the device to recognize on your computer to use the original cable and hook to the best source of power for your USB which is the back of your computer.
So.. this isn't a [FIX] - just a good tip. If you can't get into D/L mode by holding the volume button and jamming in the USB or using ADB -> Reboot Download command.. your pretty much fux0red.
I need original USB cable
I just wanted to throw in my $0.02 I needed to use the original USB cable and a port directly on my motherboard. The usb cable I bought from newegg does not work with my MSI X58 motherboard and my capitavate. The original cable does not work if I use a front usb port on my Antec P183 case. Strangly an identical usb cable from newegg that I ordered at the same time does work with my work computer, Dell X38 motherboard.
Ive had the same problem... only way i get it to download mode is via Terminal:
su
reboot download
I really cant get it to work no other way :s

honestly, i have my phone cord that came into the box, connected to an extender cable, that's connected into a usb port hub so i don't agree with what you're saying here
mine works every single time

I appreciate all your hard work on everything. I read through that post and tried to search it several times... Believe me, I spent hours pouring through the pages looking for something that would work.
No where did I see anyone say to make sure you were using the stock cable because other cables might not work? Feel free to correct me if I'm wrong...there are a lot of pages after all.
Furthermore...I'm sorry to be new to Android and to flashing roms, but we are all new at some point. No one is born an expert.
edit: I'm guessing you misunderstood the post? I wasn't posting about the method...just about the fact that many usb cables, including the micro usb cable that ATT sells, do not work for getting to download mode. If I'm wrong about what you were posting, feel free to correct me. If i'm correct, your post is quite ironic
The first captivate I had WOULD NOT GO INTO DOWNLOAD mode regardless of cable or usb port. I tried every port and every cable including the stock one that came with the phone.
The replacement captivate ALWAYS goes into download mode regardless of cable or port.
It's a tip and thank you for the. But if your phone is one of those that does not have 3 button recovery then it will likely not work with the 2 button download trick either.
USB debugging no longer activates on my phone. Activating it in settings/applications/development brings up the "Allow USB debugging?" permission window. However, no usb notifications appear, and the phone appears to be a dead device to any PC it is connected to.
This started when I accidently got into the download screen from the phone options popup. The display showed the yellow sign, android guy with shovel, and message warning not to turn target off. Phone was not connected to anything at the time.
Searching found a couple of threads indicating that a battery pull was safe to get out of it. Did same.
Since then, usb debugging (or usb anything) has been dead on this phone. Other methods of usb access (thru usb settings) have no effect either.
Tried the following...
(1) restore to my last backup rom.
(2) numerous reboots and battery pulls.
(3) mount/unmount sd card in cwm recovery
(4) clear caches
(5) changed pc's and cables (all worked before)
(6) reinstalled usb drivers on pc (worked before, didn't expect it to help since issue is at phone end)
As you can see, I'm running out of sticks to poke the horse with. Does anyone have any ideas?
Update: new kernel didn't help, either
Update2:
(a) Can't do a restore via odin, which won't detect the phone.
(b) Updated my adb (which I don't use much). adb devices command will not detect the phone via usb.
(c) Installed adbWireless which allowed me to push a stock nandroid backup to the phone. Restored that, usb is still dead.
(d) Restored back to my superdark rom, usb is still dead.
Head scratch: I'd blame hardware except that it seems to be between the settings and execution. If it was purely hardware, I'd expect to see the usual usb notifications. Regardless, it looks like I'll have to revert back to stock and let Verizon figure it out.
Update3:
(a) switched to the new AOSP rom. Nice, but no usb.
(b) switched back to superdark since I like my speakerphone and the AOSP seems to be on hold. Still no usb.
Resolution:
My apologies for not posting a resolution. My bad. After the first few days the post kind of fell off the radar and I stopped checking.
Short version...dirty usb port.
Details...after a week or so, I saw the usb icon flash in the notification bar for a few seconds when I plugged it in for a recharge. Hadn't seen that in a week, hope springs eternal!
A thorough cleaning of the usb port using a paper swab dampened with alcohol restored usb functionality. Not much dirt came out on the paper, but it must have been enough to probably bridge the contacts somehow.
At present the phone is fully functional. The original Verizon cable seems to be a little wonky. I have an aftermarket cable that works fine. It may be that the aftermarket cable did some physical harm to the contacts in the port, or the original cable is going bad (I had something very similar happen on my Omnia). Not sure.
I now use the original verizon cable only for charging at work and use the aftermarket cable for usb connecting at home.
Bottom line...if your usb goes dead as described in the op, carefully clean the port.
My thanks to all who responded...
Download screen shouldn't have harmed you.
You probably are well aware of this, but sometimes it's the simplest solution: Is your usb cable unplugged when you are trying to turn on USB debugging? It will not let you if you are plugged into a pc or mounted for some other reason. Make sure your file manager and any other rogue app is closed. Again, it does sound like you have tried all of this, just giving my best shot ar an answer.
Other then that... Has anyone else had this problem? I haven't seen it in this forum before.
The most general solution to any issue on these fascinates is to undo whatever you did to break it, it's just difficult sometimes to isolate what that event was.
Swyped w/ XDA App. When in doubt, mumble.
Thanks for the reply.
USB is unplugged when turning on debugging. I've also tried turning the phone on with usb plugged in.
The last thing I had done (before accidently activating the download screen) was to install SiMi Folder Widget. Needless to say, it went away with the rom restore.
Also used ATK to kill running processes before turning on usb debugging. Also verified that I still have root.
I've buggered the phone up before but have always been able to figure out a way back (with help from forum searches). This one's got me stuck.
Tonight I'll try to figure out if it can be odin'd back to stock and rebuild from there.
Again, thanks. All suggestions/advice are appreciated.
See op for steps taken to (unsuccessfully) solve this.
Can anyone advise how I can flash back to stock DI01 without using odin, since it won't detect the phone? I can push files to the phone via adbWireless but that's about it.
thanx in advance...
I dont know if you fixed it or not, but here is a stupid question. Are you using the cable that came with your phone? I have several cables that will only charge my phone and only the stock one enables data transfer. Hope this helps. Good luck

This may be my problem! I'm having the same similar effects. Although mine randomly shows the symbol but also says my usb is connected when it does. I've been trying to solve this for 2 weeks now! I hope this is the solution.

common problem
This must be a common problem because I've had the same issue. switched cables and viola, all good.
My exact problem solved:
USB debugging activated on phone but computer did not detect it at all, nothing what so ever. Not even on dial-up mode, or download-Odin (yellow triangle).
Drivers installed (Fascinated and Nexus for the hell of it).
Tried to ADB my into it both from windows 7 and MAC OS-X.
Hell I even tried a different USB cord.
I would get the USB debug icon in the status bar only when on windows7 machine.
I cleaned the phones USB port with the alcohol damped paper towel/tooth pick and the **** worked, first time.
Man I gotta thanks God for this site. I been ****ing with for 2 days.
Then this lil SOB acted as if nothing ever happen. I wanted to beat the hell out the lil ****er. But we are back friends now.
Thanks dude. This **** needs publicized more. I went through a few links before I found this.
I would and tell people to use something non-metallic and removed the battery beforehand. I did just to be safe.
