I feel like spamming this thread, however I tried to write this workaround which could be easily applied even by newbies and which works fine for me on Gutsy kernel 2.6.22-11 generic.

1) As root open for editing the file "/etc/rc.local", e.g. by "sudo nano /etc/rc.local" 2) Add the following three lines before the last line (which should contain the text "exit 0" and must be kept like that). echo -1 > /sys/module/usbcore/parameters/autosuspend sleep 1 /usr/sbin/lsusb 3) Restart your machine It will disable autosuspend for all USB devices without having to patch kernel. My attempts to turn off autosuspend for selected devices were not successful. Remember to remove this script once a new kernel comes out having your problematic device in the USB autosuspend blacklist. -- USB device detection problems in 2.6.20 https://bugs.launchpad.net/bugs/102659 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
