In fact: the webcam is visible under HW MANAGER if it is plugged into the usb port a boot time.
It isn't listed if it is plugged into the USB2 port after boot time but it works too !
* My C270 was always connected while I connected the 9000 pro after boot but this time, I left it connected and did a reboot.
But this doesn't change lsusb problem with no report.
From the teslog, I have now:

Strange... I thought HW manager will show all connected HW before or after boot...
Same results for USBRES which shows now the logitech QuickCam pro 9000 (but not the C270!). This allows me to get needed information for you
