I know that it can be disabled if all usb stuff is removed from kernel configuration and than loaded as module, in that case you only kldload uhci and not ehci (possible also from /boot/loader.conf) > b. the camera is supported by gspca1 (and eo ipso by v4l-ver1 if I > understand this correctly), as listed in gspcav1-20071220/gspca_core.c: > > {USB_DEVICE(0x041e, 0x4051)}, /* Creative Live!Cam Notebook Pro (VF0250) > */ > > Does this still mean that the camera *needs* isochronous transfer?

Are you sure that you bought right one (explained in link you already posted)? If you are interested in USB4BSD look: http://www.selasky.org/hans_petter/usb4bsd/ It supports 5/6/7 and 8.
