HD Crashes/hangs when charging!!

Hi,
I have been charging my HD via cable (plug charger is broken) on my mac laptop with no problems. Now i have been trying to charge it from my computer at work and everytime I plug it in the whole phone just hangs and nothing works, I can't even switch it off!! I have to take the battery out of the back of the phone.
I have tried this on both a Windows XP Proffesional and Windows 2000 pc and on both they have crashed. I have had this happen when activesync is both active and when I have turned it off on the phone. Is this happening because I have not installed activesync from the disc onto this pc? If this is the case that sucks as I thought you could just plug this phone into any pc and charge it?
Is it worth doing a hard reset?

When you connect to your PC via USB cable, besides the charging, it also try to establish connection one of which is to make your storage card a disk drive. This process will always result in the hanging and crashing and it is normal.
To avoid this, use the normal AC charger for charging, and USB cable for making connection, during which time it is assumed that you will be controlling the coyping or sync process via the PC hence the device should not be working at the same time. Not sure if this makes sense to you.
It is a way to protect the storage card from being corrupted. Only one guy should do the writing of files at a time.

Yes... Steve above is quite correct.
When selecting the phone as a storage device this locks the device and allows the phones SD Mini card to act as a removable hard drive.
If it didn't lock it down the card would get screwed up if doing anything other than operating as a storage medium.

DOH!! Ok I feel stupid now Was worrying there for a bit. Problem solved, I had the default option of it using the phone as a disk drive when plugged in, I have now set it to Activesync and also I chose Activesync when I connected it and touch wood all is fine, no freezing!!
Many thanks guys its much appreciated.

No problem Mate.... We are all entitled to a bit of 'DOHH' every now and then.

Ok so I now can charge my phone using the pc and the phone doesn't freeze. But I have just linked up the phone in Disk Drive mode as I had something I needed to transfer. The transfer went well but when I unplug the phone (and I have done the safely remove hardware thing) the phone is frozen and I have to yank the battery?? Surely this isn't right?

No... that's not right.
Is this with Vista?
I have found when using my Vista laptop my phone 'occasionally' hangs and I have to switch it off and restart but using Win XP on my other laptop it's fine.

No, it's not right, it's a bug. I'm amazed to read what you've been told so far - I mean just analyze this:

I mean honestly. How can that possibly be normal or correct behaviour?
I don't know if this is a Windows Mobile bug, or an HD bug, or a possibly a problem SD card you've got in the slot - but there is no way that any process should result in "hanging and crashing" without something being quite wrong somewhere.
You should be able to charge from any USB socket without having to worry about any of this, the advice about only using the AC adaptor etc is complete nonsense.

I am no computer jockey by any means - but I have noticed that my computer (running XP) tries to connect to my phone, as an external device and not as a phone using activesync, if I have windows media player running. With WMP (11) off, it uses activesync as normal - might this be causing this issue?

I don't think Steve meant it crashes the device and is normal.....
I think what he meant was when the device is connected as a disk drive it locks out the device (as if it's crashed).
It's normal for the phone not to be able to do anything other than transfer data when acting as a mass storage device.

I am using Windows 2000 on this PC so its not a Vista issue. And I did think it very weird, can understand it not wanting you to fiddle with the SD Card while you have it plugged in but it should release the phone when I safely remove hardware.
I am assuming no one else has this problem then? I might fish out an old 2gb mico sd card I have and see if it does the same thing, if it doesn't then its the SD card.
I will test this at home as well to see if its just the PC's here that are causing it. Mighty annoying as I have pulled the battery like 8 times now lol.

Yes... the only answer I can think of is it being the SD card that is not releasing itself.
Again it's normal for it to be locked out whilst it's connected but as soon as you 'pull the plug' you should be able to instantaneously use the phone again.
Beards

Tried this one?:
Start/Settings/System/Energy/
Disable charging when phone is ON and connected to PC.Works great for me!

Yeah I will try and find the 2GB card I have and see if that works.
And luckyuser I want my phone to be charged while it is connected though. Also my problem is that my phone crashes when I try and disconnect from the computer in disk mode, meaning I have to yank the battery.

USB problems anyone?

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

No "USB Connected" notification

I just got an HTC Hero. When I try to connect it with a USB cable to my laptop I should see a notification icon but I don't. There is nothing in the notifications panel!!

See my post in another thread in the Android Development section of the Hero forum's:
http://forum.xda-developers.com/showpost.php?p=4837803&postcount=19

I'm very new (just got the phone basically). I have an idea of what pre-rooting means but I don't know how it's done or whether I can come back from it if I ran into trouble. I started reading this: http://forum.xda-developers.com/showthread.php?p=4257045#post4257045 but in step 2 I am supposed to connect the phone via USB and that is what I can't do.

I called HTC and they had me try through various things:
Try all USB ports
Try another computer
Hard reboot - press and hold the call, menu, and power buttons
Complete restore - Home/Menu/Settings/Security/Factory Data Reset
None of it helped. Finally they asked me to try another USB cable. Fortunately I had one from a camera that happens to be exactly the same. An wouldn't you know it? Using a different cable allowed me to connect.
They confirmed the phone was originally purchased in the Czech republic and for a bit I suspected some international incompatibility but I think it's just a faulty cable. Not something you'd expect from a relatively new phone.
Hope this helps someone else.

[Q] usb debugging failed

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

Have you tried a factory data reset?

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.

Windows 7 will not detect device

When I plug my wife's phone in, most of the time it does not even recognize that anything is plugged in at all, but the phone charges. Sometimes in device manager the phone comes up with a yellow exclamation point and the error
Windows has stopped this device because it has reported problems. (Code 43)
I installed the Android SDK and USB driver.
I installed the Samsung Driver from the site.
I thought possibly it was a software issue, so I was going to try to set the phone to factory settings. When I go into recovery, there is an Android logo with a red exclamation point, then eventually it boots back into Android with no change.
I manually added the driver into android_winusb.inf as I saw on another post here, but no matter what it is not picking it up.
I want to just be able to connect so I can root the phone and put a ROM on it. The phone is pretty hosed and slow. Any suggestions?

I had this at one point. It was the device, I had to get a replacement.

Well I do have insurance on it, and I agree that is the easy way, but I really don't think the hardware is broken.
I mean it charges, so the USB port works. I think if I was able to reload Android from scratch onto it, it would work. However, every solution I see requires rooting and you can't root without USB. It is a frustrating catch 22. Any other possible solutions? If not, I guess we are screwed.
The most frustrating part is factory reset not working.

I am currently having similar problems like you, I have one USB port from memory card reader and on that port phone isn't even charging but a flash drive works without problems. On other ports (back of case and front) there is charging but computer can't recognize the device. Try uninstalling all phone related drivers or cleaning them with some sort of driver cleaner. Then reinstall driver, or let Windows update it automatically. Mine worked for a while, and in device manager it was recognized as Acer ADB.
EDIT: Hi, just to report reason of my problems, my USB cables started failing for no apparent reason, my original Samsung USB cable and one other no name have both failed. I'm currently using my old LG USB cable, wrapped up in insulating tape, but everything is working good. So try some other micro USB cable, it maybe the source of your problems.
