Hmm, well, I found the problem and also could 'fix' it: I connected my smartphone (Sony Neo V) to the Notebook to use USB tethering. I don't know what I did, maybe I disconnected the smartphone without deactivating thethering. But this gave me the issue. I just connected my smartphone again for battery charging, and due to the issue it wasn't found by Ubuntu. But while it was charging, I just played with the thethering options - and suddenly, Ubuntu detected my smartphone. Then I tried to connect other USB device - all devices are working with hotplug now.
So, this was definetly the error. I tried, but I couldn't reproduce the issue. Anyway, I think it is still a bug. I attached the relevant part of the 'syslog', whereat there are no special informations. There were no messages in dmesg. ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1082877/+attachment/3448519/+files/syslog ** Changed in: linux (Ubuntu) Status: Incomplete => Opinion -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1082877 Title: USB Hotplug is not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1082877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
