My girlfriend bought and was using a USB camera while abroad without a problem, but when she returned home the Vodafone wifi dongle, she was previously using without a problem, no longer worked. She took it to some "helpful" IT guys who decided that it would be a good idea to take a hammer to it and install Vista over XP (please, I don't want to hear about how ridiculous this is!!!). The effect was that the software for the camera was removed, and so the USB dongle worked again.... Hey presto!
Only when she went to reinstall the camera software - not plug'n'play - did the wifi dongle die again and so the realisation that there seems to be a conflict with these two applications.
Any ideas what's the likely cause of this? But I guess more importantly, how to resolve it?
