Help!!!! windows can't recognize the device

HELP!
I'm a new to PPC. I've got an O2 mini, I charged the device well just now, but now when I connect the device to my computer, always says that the USB device is not operating well and windows can't recognize the device. Is there anyone could let show me what's wrong? what should I do? Thanks!!!!!

Hello,
Are you sure you have installed Active sync in your Desktop?
Regards
Carty..

Is your USB cable plugged into a front USB port on your computer??
If so, try plugging it into the back. Some front USB ports do not have enough power to recognize the MDA Compact, and you get that same "USB not recognized" error. Most back USB ports are powerful enough.

uninstall activesync ... reboot system install again ! should work

the comupter may of just seen the modem side of it it happened to me you need to go into your hardware file on your pc and delete any modems you don't recogonize (carefull you don't delete the wrong one (i exepct no responsibility if you do)) and then re install active sync v 4.1 fom microsoft site. then plug it in again good luck

Thanks all you guys. I have got this problem resolved. There is sth wrong with my cable and I have bought a new one. Noe everything is going well.

Cant Connect To USB. Cant Flash?

So just recently my usb and sd card decided to malfunction. My usb will charge via my pc but it comes up on the pc (Vista 32bit) as 'Windows cannot recognise this device' my drivers are up to date. However in my device management i did notice that my 'Mobile Device's' section had gone
I also tried formatting my sd card using a card reader, but it wont format it
I want to flash a new ROM, any way of doing it without an activesync connection? i managed to get the NBH image on my sd card by using another storage card but i still couldnt establish an activesync connection.
Any help would be much appreaciated as this is driving me crazy
Thanks, Dan.

Just checking, you did update your usb drivers according to this guide?
Otherwise, do you not have access to another pc?
You can also try this solution, it helped another user earlier

I just edited my post above, another user came right by going to Settings\Connections\USB to PC and unticked the Enable fast data transfers.

Have you tried a simple thing like rebooting the pc? That sounds however more like a hardware issue on the pc or phone. What happens if you plug another usb device into the port eg a usb flash drive, does that pick up? In your device manager, are all usb devices functioning properly? Perhaps try to roll back the drivers on the ports if possible and re-install the usb driver update.

I Cant Roll Back The Driver In Device Manager Because It Apparently Isnt There, But Nothing Has Been Changed, WMDC Has Been ReInstalled, Net Framework Reinstalled Etc Im Just Not Getting Any Mobile Devices Show Up.

Okay, you need someone more technical than me then bro. Sorry, but I've run out of ideas.

Ah. Thanks Anyway Bro

If you've changed usb cables, and you've checked the usb to connection setting is not on advanced, then it means the usb port & possibly main board are damaged. Did you hardspl your device?

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!

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
