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.

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.

My Mini XDA can't connect to my PC via USB cable anymore, it can only recharge the battery.
My iPaq connects flawlessly, so it's not my PC.
Any suggestion ???
Mine does not connect after been run even a little bit. However if I do a soft reset and connect to the usb cable it seems to hook up right away. Whe I first got it it did not have any problems like this and I would like to fix it if possible.
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
I have read a no. of posts regarding the subject problem but found no solution. My O2 Exec is not connecting to PC with USB. Even in Bootloader, it shows usb on top when connected to the cable but is not detectable to even MaUpgradeUt_noID.
One other thing is that when its connected to PC through USB and switched on, it stop the charging and only resumes if switched off again.
Can any body tell me how to know whether USB port is working properly and solve this problem.
Hello,
Its been few months now that I have this issue, and wasn't able to solve it yet
Every time I connect my TyTN/ Hermes on the USB port of my laptop it causes a n immediate reboot. Even when the Laptop starts again when the usb ports are reactivated (the Hermes is still plugged-in) it reboots again and again ...
This is very inconvenient (...) I would say because I can neither Sync (Activesync 4.5) nor recharge my TyTN through the USB port. Even if I disable communications on activesync it does the same ...
Any ideas? anyone had similar issues?
Thanks a lot

yasou christoforos,
what happens when you plug in other USB devices, like a portable storage device or a mouse or something? Something could be wrong with your motherboard or hopefully just the OS. What model laptop is it?
I`ve TYTN and one day it stopped sychro via cable...
I plug cable - its starting charging but ASych stay absolutly quite (any notification any problem connecting) . Like I didnt plug cable
Ive made a Hrd reset , change cable but situation tha same .
any solution, please.
Did you reboot your pc? Did you try another USB device (USB port broken)? Did you reinstall activesync?
That's what i would try....
Try reinstall the active sync software. maybe the usb driver was corrupted
Because it can charge,so maybe the cable is OK( and the voltage is enough, some cable with too much voltage lose will not give enough current when pluged so that can not charge ) , problem should be of the software.
Besure if you have multi user environment. Only one user can use Activesync on Windows XP platform.
Do reinstall Activesync and do check the usb cable with any other computer nearby you if you are not living in desert.
I actually am having a similar problem connecting my AT&T 8525 to my computer. It charges, but won't sync. I had to start using Bluetooth in order to connect.
on the tytn go to settings -> connections -> usb to pc and untick the box
