[Q] HTC Hero - No USB connection, but power, no other computer works

Hi Guys,
i have connected my Hero with different cables with different computers on different driver versions. It charges battery, but there is no USB conncetion. Yesterday it still worked. I think that this is maybe more a hardware fault as a software fault. ATM i don't have a microSD Card Reader so backup my data and USB Mounting doesn't work anymore.
I use FroydVillain 1.5 and i don't want to try to factory set, because on the last restores i just could restore per usb and not per recovery console.
Does anybody know about this problem or has a good idea?
After i switched off the phone and connected, my device manager on windows tells me unknown device and says an error code that device reported an errors and deactivated 'cause of that.

Install HTC Sync

Hi tried this already with 3 different versions of HTC Sync

Uninstall HTC Sync, use USBDeview to remove the usb drivers for your phone.
Restart
Check the drivers are removed with USBDeview again
Install the latest version of HTC Sync from HTC's website
Restart
Plug your phone in
N.B. If you're using a custom rom make sure you have "Unknown Sources" checked in your application settings & "USB Debugging" checked in Development settings. These settings might help though I think the second one is for adb access and the first is for installing apps from apk files. Worth a shot though.

can't connect to pc...usb device not recognized

hey guys.
i've been using the xoom for about 3 weeks now. i have the latest motohelper driver. i'm using windows 7 x64. i've been able to access and transfer files before no problem. I rooted over a week ago and also have had no problems moving files around. accessing the sd card from the pc has also worked.
now yesterday I send my wife to move a file over, and she tells me it's not working. sure enough, no matter which usb port on the pc I plug it into, or how i disconnect and reconnect the cable on the xoom, windows gives me the USB device not recognized message.
I've tried rebooting both the PC and the Xoom. i've reinstalled the drivers. i've enabled and disabled usb debugging on the xoom. still get the same message. under device manager it shows as Unknown Device. if I go and manually select the Motorola MTP drivers it tells me it can't start the device.
we haven't done any recent software changes on the PC or the Xoom. specially not within the last two days for it to go from plugging in just fine to USB Device Not Recognized.
any suggestions?
thanks.

Cannot Connect to PC AARGH!

Hi,
EDIT * I have found a solution in that I can connect via WI fi so that's pretty good but if anyone can help me with the USB issue, it would still be appreciated. It seems that the Wi Fi connection is more limited as I am unable to view things in explorer *
hoping to get some help using my USB to connect to my PC. I've installed Kies but when I try to connect to my PC it just keeps on trying to connect but never actually does it.
I have looked for guidance on this but keep coming across the instructions to go into 'about phone > USB settings' etc etc. However, I do not have a USB settings in about phone. In fact, there is nothing at all about USB in About Phone. I do have a 'USB Utilities' in Wireless and Networks but all that gives me the option to do is 'Connect Storage to PC'. I have a memory card in my phone.
When I do connect to the USB cable, with Kies open, when windows 'finds new hardware' it keeps saying a problem occurred during installation.
Please can anyone help me out? All I want to do is basically drag and drop some files from my PC to my phone. Thanks very much for your help.

Settings --> Applications -- Development --> USB debugging.

Thanks for that!
It got me a little further. I also unmounted then remounted the SD card. However, when I try to connect via kies I now get the message:
Reconnect the device in Samsung Kies (PC Studio) mode. Current connection mode not supported by Kies.
What am I doing wrong? Do I have to re click the USB settings on the phone before connecting to Kies now that it's installed the hardware on my PC?

Turn off USB-Debugging
Don't connect phone yet
Open Kies
Open the Tools menu -> Troubleshoot connection error
Go through the guide and let it reinstall the drivers.
Connect you phone, and let it connect

The default setting has the USB debugging tick greyed out. When I select it, it asks me if I want to allow debugging.
Do you mean that I shouldn't allow debugging and then connect (after reinstalling Kies) or should I allow it and connect? Sorry for my noobishness, Android is all completely new to me.

You should untick the USB-debugging - Then reinstall drivers NOT entire Kies

OK, it's unticked and I'm reinstalling the drivers via troubleshooting.
Do I need to unmount then remount the SD card before connecting my phone? Thanks for your help btw.

Shouldn't make a difference

Bah, I still have the same problem. It just says that there was a problem installing the hardware when I plugged in the phone.
After reinstalling the drivers, i shut down Kies then reopened it. I then plugged in the USB and then plugged the USB into my phone.
When I first installed Kies yesterday, Microsoft Active Sync kept on trying to activate and ask for a CD. It kept on holding up Kies. In the end I uninstalled Active Sync. Also, I still have Samsung PC Studio on my PC from when I had a Samsung a few years ago. It was one of those old slider phones, not a smart phone. Could that be part of the problem? I was hoping to keep it because it's proved to have the best media player I've ever had.
I just don't know what I'm doing wrong here.

Try without restarting Kies.
What part of the drivers aren't installed? (Check device manager)

In Device Manager, under Portable Devices there's something called Android MTP that has an exclamation mark next to it. It says it's not configured correctly and that 'No driver files are required or have been loaded for this device'. I'll reinstall the Kies drivers now.
Thanks for this help mljjlm
P.S. Now that I've unplugged the phone, the MTP thing isn't showing in the device manager list anymore.

Of course, it's a part of the phone, and it should not be plugged in because they would have to force a reboot when reinstalling drivers (which might sort your problem btw)

Reinstalled the Kies Drivers and then plugged in my phone but got the same problem. It says a problem occurred. Same device now has a problem in device manager. Maybe I should just uninstall everything and restart? Should I uninstall the old PC studio too?

Just try the reboot without uninstalling anything and then plug the phone in when your pc has booted

Argh! Still didn't work! I think there must be a problem with my PC, well, I'll try doing full uninstalls and reinstall it all. I have to go now as well so I'll have to try again tomorrow.
Thanks very much for your patience mljjlm. It has been greatly appreciated

Are you trying to just transfer files back and forth? If so... forget using Kies.
(I don't have a micro-USB cable with me currently, so this is all from memory)
Just remove the drivers from your device manager so it's like your machine has never seen your phone before. Then on your phone enable usb-debugging.
When you then plug in your phone, you should get a usb icon up top on your phone's display... pull the window-shade down and click on the USB connection button. You should get a fullscreen window on your phone that says something like USB Connection with the friendly android waiving.
Now your PC should see your phone as a standard USB mass storage device.

try plugging the usb cable in another usb port on your computer and than try again.

You're using Kies, that's what you're doing wrong. You said in your very first post you wanted to be able to drag and drop some files from your PC to your phone, so use USB debugging (say yes when it asks you) and Windows Explorer.

If you are using a custom rom like Checkrom Revolution you will need to install the kies support from kitchen pro.
Also are you using the cable that came with your phone?
I have found a few microUSB cables that will allow charge and wont allow data transfer like the new ones for nokia devices and some blackberrys.

It worked! The USB debugging thing!
Thanks to everyone who helped me out. The forum said I was limited to 5 thanks per day so if you didn't get one of the thanks I apologise. Thanks very much!

Cannot transfer files with MTP / Device not viewable in Windows Explorer

When I connect my Nexus 7 to my Windows XP (SP3) PC via USB, it's obvious the computer recognizes it and it tries to install ADB drivers. Whether I choose to install those drivers or not, I still can't locate my device in the Windows Explorer Tree. I checked Disk Management for the hell of it and nothing but my PC's harddrives were there. There's an attempt to install drivers for "MTP" but that fails and I'm pretty sure that's the cause; however, I'm unable to replicate it, even as I uninstall/reinstall applicable drivers from the device manager the MTP failure never happens anymore. I did some googling and found a thread with someone who had a similiar experience. In turn, I downloaded https://www.box.com/s/2c25e8bc42ecce400afd to try a different set of drivers. Same problem. Driver install is fine for ADB, but still unable to see my device in Windows Explorer. I'm able to successfully connect the device to the PC with PTP for the camera. I can access DCIM and cache which can serve as a work around, but I'm hoping you can provide any ideas you might have. Thank you!
edit - ***resolution***: Ok, I figured it out...I had to disable USB debugging. I don't know if this helped either, but I installed these drivers as an alternative to the drivers that were originally installed: https://www.box.com/s/2c25e8bc42ecce400afd
While connected to PC, I switched to PTP mode because I was about to give up and just use that
I then disabled usb debugging and switched back to MTP at which point the drivers successfully installed and I could now view my device in Windows Explorer. I also believe downloading the drivers in the link above helped since the first crack I took at this was unsuccessful with existing drivers.

install pdanet on pc and it will install drivers for u so it will be recognized

Been battling with this on my XP machine since yesterday. I couldn't even get debugging to work until I installed NakedDriver. And even still, there seems to be no way to get MTP to work without turning debugging off. On my Win7 machine everything worked perfectly, both ADB and MTP, right out of the box. I have the Galaxy Nexus drivers installed on both machines (which I've read are compatible with the N7). I also have the latest version of Windows Media Player (I've read that some older versions have issues with MTP). Is anyone else able to run ADB and MTP on XP?
*edit*
A: Does PDAnet let you use MTP and ADB simultaneously? Because I really don't want to install it if I don't have to. I got rid of it ages ago (too many things starting up at boot time).
B: I have a Galaxy Nexus also, and I have no issues on the XP box.

I wouldn't bother with MTP, it's not always showing the contents of the internal storage properly when viewed in Windows Explorer.
Earlier today when I was trying to set up a backup profile for it, it didn't copy all the files off. On closer inspection I found folders like TitaniumBackup to be completely empty, which is not true according to ES File Explorer on the tablet.
I tried connecting MTP again, with USB Debugging on and off but this made no difference. Also I'm only seeing the Notifications folder instead of 36 folders on the internal storage now, really random how it's working.

asus site now has a usb driver for N7
try that

Same here. No change with the Asus drivers. Still can't use MTP when ADB is turned on.

poo. how do I transfer my audiobooks to this stupid device without working drivers?

1. Please disconnect Nexus7
2. Remove drivers on PC.
3. Toggle ON : Settings->Wireless&Networkings->More->NFC.
4. Re-connect device
Good luck !

1. Uncheck MTP, check the one next to it (Camera)
2. Unplug USB
3. Turn off USB Debugging (Uncheck it)
4. Plug in USB
5. Should say connected as camera, then a new window will pop-up allowing you to see your files.
Tell me if it works!

im having trouble too, is there any way to make the device to be recognised as a flash drive?

Internal memory partly invisible from Windows 7 Explorer

Same observation here (a few months later) on stock Android 4.1.1 rooted.
It seems that new files in the internal memory remain invisible for a long time, but so far they have become visible eventually, sometimes a day or two later. I have no clue what could possibly cause this, and I have not found any trick or workaround that makes them visible, not even rebooting. Any hint is welcome.

Didn't work. Just shows up as a camera with the limited folder access one would expect.

Workaround
I now use the following workaround.
Install SDrescan from Google Play.
Run it.
If you already had your phone connected to a computer as a media device (MTP) and are watching the contents of your SD card or internal memory in Windows Explorer, press F5 to refresh your view. If not, connect it now.
I'd be curious whether this works for you as well. If it does, press the THANKS button below.

Same issue with an old ibm x40 udated to windows xp pro SP3.
I've installed mtp driver, without success
I've "tried" to install asus driver, without success
I've tried to do as above with the help of the nexus toolkit, without success.
Everytime, the laptop recognize the device as android ADB interface.
Someone could help me?
Thank you in advance

Same problem here.. LG doesnt take care of such things.. no wonder Samsung is taking the market..

I just connected my AT&T v20 to my aliensware 15r2 laptop and was able to import my pics with no issues setting my phone to ptp. Then to access both the internal storage and sd card through file manager I set phone to mtp.
I did nothing special just plugged in phone to laptop and selected what setting on the phone. Oh and running win 10. So don't think its the phones software but maybe your computer missing certain drivers or something. So hope this helps

I had a problem on my Win 7 laptop. It connected, loaded drivers and opened as a removable drive. However, as I continued using the ?, my mouse started to register my clicks as drags and did so until I unplugged the ? .
Tappin' and talkin' with Tapatalk.

hmm. i still haven't been able to get it to work. might try using the LG PC suite pc app to connect over wifi

Anyone have issues after applying liquid spray for a screen protector? I just finished applying and now whenever I connect the phone LG V20 it still thinks its connected to usb. I restarted phone and it went into update firmware connection screen. I had to get into recovery and clear dalvik and cache and it rebooted and everything is working again. I transferred files from PC and again the same issue. Could it be liquid damage? Or is this something else? Thank you.

You'll need to turn on the Developer Option and then scroll down to Select USB Configuration > MTP > ok This is what I did to enable my desktop to read my LG V20 SD Card and memory.

Could it be a cable issue? I was warned once.
In fact, looks like nothing happens on my pc but I can browse the internal memory n sd card.

"Have you tried turning it off and on again?" - it crowd
Seriously That was the solution for me... (Oh, I miss that show so much )

i have connection problems myself but i was forced to do a hard reset after my touch screen failed and ehen ever i try to connect to pc i get device malfunctioned message and cant connect to pc and theres no was of changing to mtp or anything if i cant get intot he phone as far as i know if you have any ideas on pls let me know
