used to work under lucid, but now doesn't. I can't find the module for the usb, is this now part of the kernel and not a module? The webcam been attached to a slow speed USB device instead of the high speed device. lsusb = Bus 005 Device 002: ID 0db0:a970 Micro Star International Bluetooth dongle Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID eb1a:2750 eMPIA Technology, Inc.
