thanks for reply. I tried to run my Logitech cameras in Windows XP and Ubuntu using exactly the same hardware (I have double boot on my notebook). Since in Windows it runs (2 x Logitech Pro9000 camera at 1600x1200/YUV) without problems means that it is not the (hardware) bandwidth problem as you mentioned. I also found out that both cameras are connected to the same USB 2 controller regardless to which physical port it is plugged: $ lsusb Bus 005 Device 004: ID 046d:0990 Logitech, Inc. Bus 005 Device 002: ID 046d:0990 Logitech, Inc. Maybe if I use additional (PCMCIA) USB card it will work, however, as I mentioned in Windows it is not necessary. If you have any other idea what might cause the problem I'll be obliged to you for any hint.
