Yep. I think this is it:
Sometimes I use 3 webcams with different drivers. But It happens that one or more webcams will crash. It says 'cannot initialize driver'. (in the channel or even in screen)
It can happen that the Layer and/or the channel were the webcam was in, will freeze and even that is no possible to drag in any new footage.
Mostly this occurs due USB banwith problems. It is very small. Sometimes even one cam can take all usb space. If you use a usb keyboard and mouse and even a USB MIDI controller as I do, it can get very buggy.
If my webcams crash I have to reinstall them with the install CD from the cams, otherwise they wont work in Resolume, but they work in XP though.
Be shure when you plug in the webcam that XP detects it, like 'New hardware detected' and that it will initialize the drivers correctly. Before you start resolume!!
In resolume use the source webcam feed instead of the live feed.
The source of the webcam uses the correct drivers for your cam while the Livefeed uses main (other) WinXP drivers.
Good luck
