[Q] cannot change connect to pc connection/connection default as charging

i had notice there is alot similar post to this problem but none really solved it. so i start this thread to make it more specific
1) once connected to pc, my wildfire automatically charge
2) no pop-up or option on the top to slide down to select either htc sync, mount as sd card, etc
3) tried reboot, mount unmount card, untick usd debugging, changed other rom, but still not working.
4) if connected to pc still automatically charging even if i change "default connection type" to disk drive, or usb tethering
5) i tick "ask me" so i can choose the connection type when connect to pc, but when connected to pc, nothing. just charging.
i'm rooted, using hg hybrid v3 (problem was there before i flash HG rom). it used to work before. i dont recalled when was the last time it start to behave like this. all this time i thought i set the connection default to charging, but when i want to transfer songs, only then i realised this problem. i m not sure which custom rom might cause this problem (if it does) because i had flash more than 10 roms

i have same problem with cm7

I haven't try to format my sd card. because when I connect without sd card, still no connect option. if my card is malfunction/the main problem, then my phone should work fine n show the connect option after I remove the card, right? (I do have connection option on the setting. what I meant no connection option is the pop up conection menu+connection option on the top bar. changing the connection on the setting change nothing)

I too have this prob but never questioned this as i never use htc sync. But if u really wanna use it try this i'm not sure it may work or not but mostly its due to driver problem:
1.Connect your device in htc sync mode.
2.Uninstall or Remove all drivers of htc and also htc sync.
3.Disconnect your device and Restart your pc.
4.Reinstall htc sync and connect your device in htc sync mode.
5.It'll install fresh drivers for your device and if asked to restart then do it else run htc sync.
If you are running vista or later try to run htc sync in administrator mode.
I'm not sure this method work but there's no problem on trying it. Reply your result after doin above steps

I also think the problem might related to my driver but I remember that when I first connect to my pc, there will be pop up menu, and my phone automatically recognized as "disk drive" (I m not install HTC driver yet. infact ,I install the driver after my phone connected to my pc through disk drive connection since the driver located on the SD card). nway, I"ll try your method and post the result later.

I just notice this might not work..the problem is I cannot change the connection. even if I did, it doesn't change the connection. it just charging.. as if I put it on default "charging" as it connect. but I will try later anyway

When i connect my phone the debugging icon shows up and my pc makes the noise but doesnt let me choose mass storage (running cm7). it shows up on my pc on drive f: but when i click it just says please insert a disc into removable storage F:

xynok, did u tried untick the usb debugging? go to setting, application, development, untick usb debugging. u still lucky at least it prompt u something if u connect to pc, mine nothing. its like I plug it to the socket wall not pc

not working..

try this if u r using sense roms . Also try this for AOSP roms, if there is an option(i dont know about AOSP).
Go to Settings/Applications/Manage applications/All/
Then search for "Connect to PC". Actually in stock roms that was an app by htc. But there must be something similar to that in AOSP roms. Then open that and select, "Force stop" , "Clear data", "Clear cache".
I dont know for sure if that solves the issue or not. But have a try.
And by seeing this thread, actually i got a doubt, "can we synchronise the htc sync in AOSP custom roms". Since AOSP is nothing but removing the HTC crap. Can someone confirm this .......

nope. still nothing. anyway since it had this problem, I had wipe my wildfire few times, n try different rom.. maybe it is because of faulty cable. but if the cable is the culprit, why it still charging? is it possible the cable is broken but still can charging?

Not telling that it should be, but definitely there is a possibility of a cable culprit.
The USB male/female end has 4 connections in which two connections are used for voltage and the remaining two connections are used for data transfer.
There might be a possibility that the data connection got broken with voltage connection retaining. Try with another cable (any USB v2 cable).
And one more thing, for having the disk drive option, nothing need to be installed in the pc. U need to install htc driver in the pc only if u want to use usb debugging , usb tethering.
[But at the wildfire end the cable has 5 connections and i dont know what the 5th one is for. mostly it will be a NO CONNECTION]

Now i got another idea to diagnose ur issue.
Well do u know of application "pdanet". It uses USB DEBUGGING feature to tether ur phone internet to PC. Actually usb debugging can be used both under charge mode and disk drive mode. What u can know on doing this is whether usb debugging through ur phone is working or not. U can diagnose the thing while checking with every app that uses usb debugging. So try it. Enable the usb debugging in phone first.
---Install pdanet desktop version and follow the setup instructions. It asks to connect ur phone during setup to install usb driver and also pdanet.apk to mobile. Connect ur phone with usb debugging enabled. I doubt whether desktop version installs or not because of ur issue. Mostly desktop version of pdanet will not install without a phone connected having usb debugging enabled. And if the desktop version is installed successfully, that means ur phone usb debugging is working. And if desktop version is installed successfully, that means it also installed the mobile version of pdanet.apk to ur phone (which says that data transfer is working). Then open the pdanet on phone and enable usb tether. Then open pdanet from desktop and connect. Then see whether u r able to access internet from pc.
---One more method is try to use ADB from android sdk. It also uses the usb debugging feature.
If adb and pdanet works, that means usb debugging feature on ur phone is working. If it is so, then it is mostly not a cable problem (as far as i know). And if they dont work there is a chance that it is a cable problem.
......................................................................................................................................................................................
And one more thing. If u have used a stock rom (freshly formatted), and faced the issue, then it is mostly not a software problem. Then it might be cable problem or some kind of problem in ur phone. Also check ur phone radio version. Thats all.

bharatgaddameedi, i cant install pdanet. it say android phone not detected. error =103. i think u were right. its hardware related problem but its look like not the cable. most probably its my wildfire usb jack. i test the cable with other mobile, its working (test it on nokia 5800). before i had this problem, sometime i use htc cable to transfer data for my 5800, and some time i used 5800 cable to transfer data for my wildfire. the difference between the two cable pin might damage my wildfire usb jack.. (u said htc cable got 5 pin, so i asume nokia got 4?)

So, pdanet not detecting the phone means usb debugging is also not working under charge mode. That should be phone hardware related problem like u have said about usb jack.
And No. All the micro USB version 2 cables will be the same. Its same for 5800 and wildfire. I use my previous 5233 cable to my wildfire even now.
The usb jack of wildfire may damage if u have used it in an improper way. Something like pressure on the cable when connected and so on...
So, its not something we can solve here. That should be given to service centre as far as i know

Can't be. I am using my N82's data cable for data transfers on my Wildfire from Day 1. The provided data cable is pretty much permanently attached to the wall charger.

I accept the fact that it might be hardware problem but there is one more thing I want to try. how about flashing stock rom from pc? flashing 2.1 is ok since it can be rooted again. I had flash stock rom but from the clockwork mod, not from pc, and the hboot is been remove for save flashing. I never try this before because all this time I thought that the problem was cause by custom rom, so I just need to find the right custom Rom.

How can u flash a stock Rom from pc when the usb is not functioning. RUU will not work.
Things get worse when basic things stop functioning.

[Q] USB Device Not Recognized

Good day,
I'm having problem with my DHD unable to be recognized in my Win 7 PC. I have already install HTC Sync and also tick on "Ask Me" for Connect To PC setting. I'm running on stock 3.13.707.4 ROM with S-ON and unrooted. Even restart to Fastboot my PC still unable to recognized my DHD.
From Googling it shows many Desire having USB-Brick problem, does this problem also applied to DHD? Is it my phone is hit by USB-Brick? Any guide to solve this problem? I've tried flashing older ROM via Bootloader and PD98IMG.zip but it won't allow saying something like the ROM is older version.
I just bought this used phone for about a week so I'm still not sure on how to solved this problem. any helps is much appreciated.

are you using the original cord that came with the phone? just any old usb cable won't work
also you can't flash a new rom without rooting and gaining S-OFF, you're unrooted and S-ON, that's why you get the "version is older" message

I bought the phone and it came with 1 cord (with HTC label) that can be connected to the charger, I guess there are only 1 cord for charging and connect to PC? This is the cord that I use. In addition to that I have also tried Motorola, Sony Ericsson (both also for Android phone) and Nokia cord but all can't.
The ROM is actually older version stock ROM from RUU.exe. I saw from few Desire thread they were using this method to restore the ROM to before the USB Brick condition so I thought to try it.

BUMP!
Anyone know what should I do to resolve this problem?

Are you running the very latest HTC Sync on your PC? I'm using 3.0.5606. You can get it here: http://www.htc.com/www/help/
Also, connect your phone and go into Device Manager on your PC. Check to see if you have an entry for Android USB Devices and that the phone shows up. See attached screenshot for how mine looks. This is the best place to check to see if your PC has installed the drivers correctly.
In answer to your question about the cable, yes it's the same cable that attaches to the PC or to the mains charger. I've sometimes had connection problems caused by a dodgy cable, but I've used others apart from the HTC one without issues.
Edit: Also, when you install HTC Sync it should warn you to disable Antivirus software during the installation. This can be really important! I ignored it the first time around, thinking it was just a silly precaution, and had loads of problems with the phone not being recognised. Had to uninstall, temporarily disable AV, and re-install HTC Sync. Once it has finished installing, you can turn your AV back on.

Thank you for your reply preacher6.
Yes, I'm using the latest HTC Sync, v3.0.5606, just downloaded yesterday and reinstall everything.
When my phone connected to the PC it didn't appear as Android USB Device on my Device Manager, it only appear as Unknown Device in USB Controller:
So I guess I can rule out the cable as I have tried about 4 cables already.
For the installation part, I have disable the anti virus and also running the setup program as administrator. When installing there is no problem whatsoever that crop out.
Another point is, even on Fastboot it appear as Unknown Device in the PC.

I would try to update the driver manually - right click on the Unknown device, go to "install driver" or "update driver", then browse to the "Program Files\HTC\HTC Driver" folder. See if it picks up and installs the correct driver.

I've tried manually update the driver as per your advise but it says there is no compatible driver in that folder even though androidusb.inf is in that folder.
I'm running Win 7 64bit. does the driver also work for 64bit OS?

Should do, yes, I'm on Win7 64 bit myself. There is this folder on my PC:
C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Win7_x64
Is the unknown device present when the phone isn't connected? Just to make sure that is actually the phone - if it's still there when the phone isn't connected, it's some other device.
Otherwise try uninstalling the unknown device and then rebooting the PC, then forcing the installation of the drivers again.

The folder is same as yours.
The unknown device does not present when my DHD is not connected, so I'm certain it is the phone that appear as unknown device.
I have tried uninstalling the unknown device > reboot PC > installing the driver but it still won't install.
Another thing is, I check on the Device Manager > Unknown Device properties > Details" for it's Hardware Ids and it shows as USB\UNKNOWN. I think it should show a strings of the device id? Correct me if I'm wrong.

Yep, there should be a proper device ID string, on charge mode mine shows a hardware ID of USB\VID_0BB4&PID_0CA2&REV_0226&MI_01.
At this point the best thing I can suggest is to try on another PC. If it works, your drivers are screwed up and you'll need to strip them and reinstall. But if it doesn't work on another PC, it's possible you have a hardware problem with the phone.

I need help too (HTC Desire Z device)
Is it hardware problem? (I already purchased new system board).
For me it looks like hardware problem, because device does not accept bus address, do not show USB strings/VID/PID (Tried different cables/PCs/OSes (I have OpenSUSE linux, but phone does not connect to usb on any PC, Windows PCs even do not understand that something plugged in)).
No problems with USB-connector (checked resistance), but I do not see pull-down resistance with my tester.
But all other functions work well.
UPD. Tried to connect from FASBOOT/HBOOT/Android - the same result, device does not accept bus adress. Additionally it charges without problems, but when I connect phone to USB no pop-up/information at top bar appears.

Sorry, it looks like I explained my question wrong (I'm Russian, and English do not native to me). Let me try reformulate:
You said "Yes. Holla if you still need help" so I believe that you were able to fix "Device not recognized" problem. So I'm asking - how did you do it? Did problem was hardware or software?
For me (look at symptoms at my previous message) it looks like dead USB controller in phone. But maybe it very strange software problem (USB-controller firmware damaged)?
Did I explain it clear now?

Install the SDK on PC and update all android versions.

Well guys it was just my PC, i made a system backup for four days and that was all the problem(the USB port of my PC)

After installing and updating SDK...go into platform folder and open it. Hold mouse in field and hold shift and right click mouse. Chose "open cmd here"..that will open a cmd prompt window. In regular mode on phone,type "adb devices" should return numbers (ex: hta3829g)..if in bootloader mode,type "fastboot devices" should return numbers.
This SDK helps PC see your phone when its plugged in. Especially handy when a PC won't install drivers for your phone

[Q] Laptop won't detect phone!

Laptop won't detect phone, tried different PCs, different USB cables, and even got the USB port changed but still no luck. When I connect it to my LED TV, the phone says it is connected in USB mode and disk drive option works. However, when connected to laptop, it goes only into charging mode. Downloaded the HTC Sync Manager too but still no detection of the phone whatsoever. Help, pls?

I bought it off the internet a month back. The guy I got it from said he never rooted it. So, no custom rom or any modding done yet. I'm currently using Ubuntu, this too doesnt detect my phone. And I tried again on my LED TV but the USB Connection was established in like 2 seconds so there's no problem with the port or the cable. What drivers do you use? My phone doesnt even get detected by the HTC Sync.

All of these and still nothing
When i connect the phone to the pc the phone starts charging and the PHONE makes the normal beeping noise when its charging but nothing on the pc, when i connect something else to the PC the pc does a little beep to tell its recognized the usb device connected but with the htc one m8 it doesnt do anything, Ive been into device manager and nothing there in regards to the phone.

Uninstall all HTC Drives and HTC Sync.
Plug the phone to USB, and see if the PC responds. Does it try to automatically install HTC Sync? If so, don't allow it.
Does the PC recognize the phone at all in Device Manager (with all HTC software uninstalled)? If so, select the option to select drivers manually then pick generic Android MTP device (or something to that effect).

Have you rebooted the pc... Then plug in the phone?
And did it work on that pc before?

Not a good sign that your PC doesn't recognize at all. Its possible the phone's USB port is damaged, so it will charge but not connect to sync to data.

[Q] USB Issue after Update

Hello,
I couldn't find anything on the web and in this forum to my issue.
I have a USB issue on my HTC Desire HD which started after updating the Stock ROM some years ago.
The Device is S-ON and unrooted.
The issue is that I can only charge the battery on any USB-Port on my PC. There is no popup window in which I can choose "disk drive", "HTC Sync" etc.
I tried a lot of other PCs, other USB-Cables (including the original one) and every single USB-Port.
In the "Connect to PC"-Settings th eoption "Ask me" is activated.
The weird thing about this is that on one PC I have a USB-Hub, more likely a card reader module with a USB-Port and on this USB-Port everything is working (I am prompt for the choise, I can go into "disk drive" etc.). But this is the only USB-Port with which it is functioning.
Are there any known USB-Issues after system updates on the HTC Desire HD?
Is there any way I can get the USB functions working?
Thanks

Nope. As long as at least minimum of One USB-port detects and works fine, means issue lies somewhere on those ports or drivers that you've installed on any pc. Try uninstalling them n make sure you've HTC Sync on every pc you try.
I'm no longer on Stock ROM, but on every Sense based rom, when you connect your device on Notification panel on your device will prompt to choose between Disk drive or Just USB, try choosing either one but only after updating drivers/htc sync for pc.
No issue seems like have been noticed till date as you're alone, n possibly an easy fix. If device works flawless n holds charge means USB-port issue or pc end problem only. Don't worry just update drivers and should be good to go. Also use factory reset option optionally if still problem persist.

I've already tried everything you said.
I uninstalled and updated the drivers and HTC Sync on 5 PCs.
I also tried to return to factory defaults.
Everything with no success.
And the fact that there is a USB-Port that is working, shows that it is not a driver or pc problem, because on the same pc the other USB-Ports are also not working.
Could it be that it is a hardware problem with the HTC?
I just don't know what the difference is between the card reader USB-Port and every other straight USB-Ports....
