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.
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
Here are some videos:

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.
Hello i need some help
Im using Windows 7 64 bit.. and befor all was fine now from some time i see there have some problem and i cant understand why...
I have Blackstone and when i do Disc Drive mode for "Faster" Transfer is very very slow LOL.. at 1st i was thinking that my SD card is the problem but i use the same SD card from 2 years and never had problem like this befor.. also few times i FORMAT the SD card and etc but again the problem is the same from 1-2 weeks even the Active Sync is faster than Disc Drive yesterday when i do format my SD card i try to put back around 3 GB of files.. and was writen remaining time 15 Hrs WOW so i just leave the phone all night the files to be transfered.. also i try to copy this 3GB with Active Sync and was done for 9 hrs so faster than the Disc Drive witch is not normal.. now im starting ot think that there is some problems with the drivers?!?!
Also sometimes.. when i Disc Drive my device there is a pop up messege " THIS DEVICE CAN PERFORM FASTER" but when i click on the setting i cannot see anything so i think the Drivers have problem or the Settings or maybe both.
PLEASE can anyone with Windows 7 64bit can tell me what i need to do.. what settings you have?! where to change them and maybe do someone have a NEW USB drivers ?!
Will be very glad if someone can help me out because right now i need to wait a lot even if i want to transfer one Mp3 to my device!!!
I chek this.. also with Another Blackstone and is again the same witch mean Is not from the Device or the SD card is something related to the USB drivers/settings etc.
THank you in advance
If it's any comfort, I know how You feel I had a similar problem with 1GB USB stick and Vista. After hours of research, applying 4 (yes, four!) different hotfixes and bunch of registry edits and restarts, I was still in the same spot where I started - meaning transfer of some 700MB of data to the stick took more than 1,5 hours, which is nonsense. Anyway, as far as I am concerned, there is a problem with some of USB handling in Vista (and possibly maybe on W7 too). When it's one large file, it's quite OK, but when I have 5-6 thousand small files, it takes forever to copy. The point is, I think it's likely that the problem is on the PC side rather than on the PPC side, so maybe You can narrow it down some more. I personally gave up and went back to XP - no problems ever with such things. MS is really "improving" their OS

Hello all!
I'm just guna say, this might get long winded so, TLDR, Nexus 7 has no OS, I can get into the boot loader, the only thing I can actually do is get into TWRP v2.8.01, computer doesn't recognize it, can't get it to even see a flash drive that I've formatted to Fat32, now what?
For those who want some background. I got my N7 refurbished from ebay, if that matters at all. First thing I did was update it to Kitkat and root it. Installed some apps and was happy with it for a few months. About a month or so ago it stopped connecting to the Google Play Store. I wasn't bothered by it too much. But as time goes on, I find new apps and would like to use them. But obviously can not.
So, just to be safe, I wrote down all the apps I still had on it just in case they didn't want to load back up. Did a factory reset, still couldn't connect. Looked online and cleared caches and stopped services. Still didn't work. When I went onto the GPS, heh, on my computer it said that I had no devices so that was a clue of some sort. I could still go onto Youtube and log in and use it just fine. Just nothing in the store. So I decided to try something else.
What that was was to clear all my data with TWRP. Went to put in my email and password, couldn't connect, tried another wifi connection, still no go. I was able to use it, but the Play Store still didn't want to play nice. So in a bit of, "rage" we'll call it. I formatted it and now I'm where I am now. With a tablet that won't boot, just sit at the Google logo for up to 5 mins, as long as I've let it sit there for anyway. I have downloaded the Nexus Root Kit and tried to use that, but my computer won't even see my N7 now. In the bootloader or TWRP. So I can't even get anything onto it now.
So, what now? Do I have a bricked tablet that won't do anything or is there something an Android Guru out there can help me with? I'd like to keep it. I mainly used it to read and for various videos.
I have posted on forums.androidcentral but after a week and almost 300 views, no one has made any comments. I'm sorry for my ignorance if I'm missing something.
Thanks! I shall be hoping for good news.
So, does ADB recognize your tablet or not when you type "fastboot devices"?
I take it you mean shift+right clicking in the platform tools folder, open command window here, and typing that into the command prompt? If so, then no, it doesn't show up.

Can you go into the bootloader? Did you install the right drivers?
I can get into the boot loader just fine. Recovery sends me to TWRP 2.8.01. I've got the drivers from the Android SDK Manager, Rev. 11 apparently. Would that be any different from the standard drivers that get installed when you hook up the N7? Well, when it works?

That is correct. Use this: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
And if doesn't work check in device manager.
If it works flash the latest factory image and then you will be good to go
I've already had that installed and set up and nothing pops up in the device manager. I've also tried all the usb ports on my computer to no avail.

Then try the driver manual in nexus root toolkit
I can follow the instructions, but that doesn't resolve the fact that my computer can't see the Nexus .
go into device manager and delete every single entry that suggests anything to do with a phone, tablet, google device, nexus device, ETC. if you dont do that first, this will probably not work.
once you delete every single entry in there, go to the top command bar and somewhere in those menus is an option to show disconnected devices. delete everything again as above.
now, does your tablet still charge on the AC plugged into the wall? does it still charge when plugged into the computer usb? drivers are NOT required for usb to supply power. if so, the usb connector is probably OK. if not, your usb connector may be toast.
next, connect to the computer. does windows show any device connected? if not, try a different usb cable. report your findings back.
Sorry for the late reply.
There is nothing in the device manager related to my Nexus, which is odd, it had entries for flash drives, a camera, and my phone. All of which were in the disconnected devices. I got rid of just for the sake of it. Nexus charges just fine, either from the wall or any of my usb ports. If there is no way to make ANY computer see my Nexus, is it safe to say it's bricked?
I do have a cousin who's fluent in Linux if that means anything. I know that Android is a flavor of it. Might work better if both devices speak the same language. Grasping for straws I know.
Again, thanks for the help fwayfarer, GtrCraft, and Fobos531!
If I am reading right, you did NOT try a new USB CABLE yet, did you?
Try a known good USB cable, what I mean by that is try a cable you KNOW works for data transfer on another device and report back.
Connecting it to a Linux machine isn't going to make any difference in my opinion.
I have 2 cables and they transfer things just fine with my phone and my Kindle. I just downloaded everything off of both things, and transferred them back. No issue with the cables. I just popped open my Nexus and it looks like the usb connector and ribbon are fine. I did wiggle them a little but to no avail.
Pull the battery cable, smash the power button for a few minutes, reconnect and try again. It won't recognize a USB thumb drive in bootloader or recovery to my knowledge, BTW. I noticed you mentioned it not seeing one.
I unplugged the battery, hit the power switch for a while, plugged the battery back in, plugged the usb back in, nothing. Still nothing. I had read before that you can put the version of android you wanted on a flash drive. With an otg cable you could use that to update/install what you wanted.
You're probably right, I haven't tried using one in recovery for a long time. You didn't change the battery or anything recently did you?
Nope, haven't replaced anything in the Nexus. The only thing that I could think of that could be wrong is the usb connector. But for it to "fail" at the same time I formatted everything, too much of a coincidence.
Over a week bump
I ran into a similar problem about a year ago. Unless your tablet is connected to the computer you will not see it show up it the windows device manager. You should be able to connect your N7 to a work computer & it should go out for the drivers. If not, then you are Sol. You might have a blown main board.
The only thing my N7 does when I plug it in, is that it charges. That's the only thing I can get it to do. Well, this sucks. If I really have a bricked, or worse, tablet, it's still good for its screen and other bits.
