EXEC Not recognised via USB

I get a rather frustrating mesaage when I connect my O2 Exec via the USB port. It takes about 3 time before the connection with the comp finally happen.
The message is - 'USB Device not recognised' ' One of the USB devices has malfunctioned ........'.
Does anybody else have this problem and can anybody help?

Yep
I get the same problem but only with one PC. It happens on either USB port and is not helped by adding a USB hub. As such i am investigating the problem as if it is PC based.

Is this with ActiveSync or CardExport? Either way try rebooting PC first, wait for it to finish loading Windows. Power off your Universal, connect cable to Universal and PC then power on Universal. Seems to work okay for me. If you are using CardExport, remember you can't change modes while connected.
Regards

I have an O2 xda mini and that connects first time every time.
Found it strange that the Exec did not do same!

I have this on one PC - make sure the XDA is turned off first. Then plug the USB cable in and it should power up by itself and get recognised by the PC.
Also make sure you are using the very latest ActivSync (4.1 I believe).

Thanks lads - connect the cable while the Exec was off and it cobnnects first time. Good stuff!!
Why is that?

I think its the phone not the pc that is at fault, as i had a usb car charger and a usb power charger, both using a standard usb lead and the same fault applies, obviously just charging, AS wouldnt happen would it lol.
me missus just got a wizard and none of these faults occur on it

I concur that the plugging in USB while Uni is switched off is much more successful. Can I check with you guys - can you activesync by USB while bluetooth is on? I've not been successful with that.

Computer reboots/BSOD when connected to USB

Hello there,
Running an O2 XDA Mini S stock ROM with ActiveSync 4.1 on a Windows 2000. Initial ActiveSync went without a hitch, with the mobile able to sync with exhange server nice and smoothly. Then later on, whenever the phone is plugged into or unplugged from the USB data cable, the computer just reboots.
Are there any known issues with this? Could it be a problem with the USB drivers on the computer or the ports themselves? The phone developed this problem whilst plugged into an externally powered hub, but plugging the phone directly into the motherboard USB ports produced the same problems.
Thanks in advance,
Andy.
EDIT: I've attached a CPUZ report of the system so you can easily see the spec of the computer.

It's possible that your phone conector are damaged and makes a cortocircuit when you connect to the cradle.
Try whitout pluging the power in the cradle, only connecting to the usb port of the computer.

That could be a possibility, but not using a cradle here, just USB Cable.

Try deleting all of the USB controllers in Device Manager then rescan to pick them up again. resolves a multitude of USB problems

Just tried that after reading your post, no dice Thanks for the help so far though

if u r using a firewall , either disable it or delete it all to gether
i had the same problem with sygate personal firewall

If you have Kaspersky AV, download the newest version on the kaspersky website! It's not a very good idea to uninstall or disable the firewall.

Thanks for all the help guys, definately gave us a few extra things to try
Just to update the thread in case anyone comes across a similar problem in the near future;
After exhausting every possible Driver reinstall/upgrade/reformat we have come to the conclusion that it's faulty hardware (USB related) on the motherboard, so will be transferring the PC out. The PC in question is a good 5 years old and it's the MD's, so he was due for an upgrade in the near future anyway

a serial problem with no solution to this moment!

-you should try using another usb cable
-Do not turn on firewall on your computer
-try to update drivers

In most cases when a system loses a usb connection, once a successful one has been made, then it drops this is usually down to a power issue.
This could be down to a bad cable, or a loose wire in the cable or phone.
Try another usb port, or make sure you dont have many devices connected to you system via usb.
In most cases the more devices you have connected via usb the power it is taking possibly away from other usb ports that require that extra power.

[Q] I cant connect ny hd2 on my computer

Hi im new here
I got my hd2 when it first came out running winmo 6.5 now i just cant connect it to the computer tried more than 1 computer and more than one cable when i connect it only charges i receive nothing on the computer like i used to before i have tried everything in the setting usb to pc still same thing
please help me how can i connect it
and i also tried hard resetting it more than once same thing

under settings tab -----other , there will be a usb to pc button

I bet you have tried all setting changes so since you have done a hard reset and it still doesnt work, it has to be your micro USB cable. I had the exact same problem as yours and i feared that it was the micro USB port that was faulty. But then i tried a different micro USB cable and it works perfectly. Hence, it is likely to be your cable. Im not bad mouthing HTC because of the amazing work they have done, but their accesories seem to be a bit down on quality. My original micro USB cable is now frayed and almost severed, my Touch HD micro USB is also frayed and the original earpiece is now experiencing audio balance issues.

the thing is the cable that comes with the hd2 i lost it but when i was using it i could connect
but now im using nexus one cable and Nokia n900 cable to connect to the computer and it just charges like i said nothing appears

Have you tired different ports in your computer or tried reinstalling the drivers? To do that, uninstall the Activesync or Windows Mobile Device Center in your PC and reinstall it. Then try. If you still cannot connect your HD2 to the PC for USB mode, then im afraid the micro USB port in your HD2 is faulty. Try the above. Meanwhile, use the SD card method for flashing or transfer files using wi-fi or bluetooth.
Good Luck

If your HD2's USB port doesn't work you can connect to ActiveSync via bluetooth. I do that very often for a quick synchronization, and since HD2 has an Activesync profile it's easy to configure...
Anyway, check that "accept USB connections" option is selected in your pc ActiveSync configuration.

Most probably, he's facing the da** usb port breaking issue.

[Q] USB connection not working

Hello everyone, this is my first post and it´s about my Defy, which, for some reason, the USB port does not work to access the phone and/or the SD Card.
1: I did a soft and hard reset and the problem persists.
2: The phone does not show up on the device manager under Windows so not even an error message saying "Device not recognized" or something. Also, it won´t show up in Ubuntu.
3. The "Connect your charger" message shows up all the time.
4. No notification in the phone when plugged to the PC .
5. Even though I can´t access the phone from the PC, I still can´t charge it through the USB port.
6. I can connect/access the phone and SD Card using Wi-Fi (Motorola Phone Portal) but not USB. I can see "Plug in USB to launch" in Phone Portal but cannot press the button, only the one referring to Wi-Fi.
PS: This is my second Defy, the first one got the same problem so I got a new one... sadly, the it happened again.
PS2: I wonder if a USB 3.0 port has to do with anything? It´s the only thing that I noticed before the USB stopped working.
Any help or hint is greatly appreciated.

well, i don't think it's an usb3 problem ...
to be sure you could try to connect your phone with an older usb2 port computer ...
is the phone charging on wall charger and usb-cable ???
if not, it really sounds like a hardware failure ... then i would send it to customer service and tell them that there is the same problem again .. maybe the just repaired something and it's faulty again ... be sure, that they are changing the faulty things ...
if your phone is charging on wall charger, it could be that it is an problem with your pc ... try another one ...

1. I mentioned the USB 3.0 port because it was the only common thing just before the usb conection stopped working.
2. The phone charges normally using the wall charger or usb (2.0, 3.0) cable through the PC.
3. It does not matter what PC is connected to or the OS (Ubuntu, Win7)/
Thanks for the response!

It is possible to brick it. Wtih some phone's it seems to be a common error for usb ports to be blown.
Could also be the cable... My cable that came with the defy was already snatched after a few months. My screen started going on and of when I was charging it.

Is there a way to check for faulty hardware-related issues?

just test different cables, computers or even mobiles ... then you will see, what is faulty

What I meant was some software that check or even some kind of physical device.
Anyway, I know it´s not the cable or PC faulty but the phone itself. But I want to confirm if it´s software or hardware related and if there´s a fix.
Thanks!

Try using USB with logcat open. You might see something in the log that will tell you what's happening
