ActiveSync failing to detect C500 Smartphone

[Guest huw.evans]

I have a C500 Smartphone and version 3.7.1 of ActiveSync installed on my Windows XP (service pack 1) machine at work. Recently, ActiveSync has totally failed to detect the Smartphone when I plug in the USB cable.

I have tried reinstalling ActiveSync. I have tried going back to version 3.6 of ActiveSync. No joy. I have removed the USB host drivers and windows has reinstalled these, no difference. I have rebooted a number of times and have killed the activesync process but this hasn't made a difference either.

When I plug the phone in Windows detects the new hardware, even telling me its a C500 Smartphone, so the driver is working and the cable is OK.

Does anyone have any ideas of what I could try next? I *could* reinstall my Windows XP machine but that seems a little over the top, and it's also an incredible waste of my time.

Any help would be good as it's a bit pointless having a Smartphone that can't interact with a PC.

Might it be the firewall settings ?

Are you using a USB hub ?

Have a read of this thread and see if any if this applies to you :
