Well, I don't know, I was very careful and took the following into
consideration:

a. this camera is USB1.1 compatible, e.g.

  http://www.qbik.ch/usb/devices/showdev.php?id=3D4040

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? If
yes, is there an easy way to compile and test that usb2 stuff on STABLE?

(I also forgot to add, playing with various USB settings in BIOS didn't
help, such as turning off USB2 support, turning on USB legacy support,
and lowering USB2 speed from Hi to Full.)
