Hi, I've been experiencing the same issue on my Ubuntu 11.04 or 12.04 installations. Usb devices suddenly stops working after I plug/unplug some of them. I have a USB-Serial converte and an external SD-card reader and both seem to trigger the problem Only "workaround" is to reboot the system (which is not a solution, obviously). As it looks like from dmesg, the crash of khubd is at the root of the problem, and being a kernel thread can't be "restarted" other than rebooting....
Looks like a common problem, across different distributions... thanks Fabio ** Attachment added: "several logs" https://bugs.launchpad.net/ubuntu/+source/usbutils/+bug/570049/+attachment/3394401/+files/lsusb_hang.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/570049 Title: lsusb hangs forever To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usbutils/+bug/570049/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
