Maybe I got the wrong bus/port: $ lsusb Bus 001 Device 002: ID 0402:5602 ALi Corp. Video Camera Controller
also: $ ls /sys/bus/usb/devices/ 1-0:1.0 1-5 1-5:1.0 2-0:1.0 3-0:1.0 4-0:1.0 4-2 4-2:1.0 5-0:1.0 usb1 usb2 usb3 usb4 usb5 There is no "1-2" device! I think it is 1-0:1.0 but: $ sudo su echo disabled > /sys/bus/usb/devices/1-0\:1.0/power/wakeup -bash: /sys/bus/usb/devices/1-0:1.0/power/wakeup: Permission denied -- cannot suspend usb devices on lucid https://bugs.launchpad.net/bugs/515109 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
