> gouri, thank you for providing the requested information. Could you please test the latest mainline kernel (not 3.12-rc7) via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-trusty/ and advise if this is reproducible?
Hello again Christopher, * Short answer Reproduced with 3.13.0 from URL above. Plugged 8 times in a USB3 port. First time yield a success log, others yielded a failure log. Interesting fact : I noticed that when device works in a USB3 port it is recognized in kernel log as "high-speed" instead of "SuperSpeed". It already happened as you can see in bug description, look for "Jan 16 18:27:45". So, it may be that the device actually never works when correctly recognized as SuperSpeed, but works in a USB3 port only when "by accident" it is only recognized as "high speed" (USB2) ? Regards, * Long answer I used a 3.12 because I aimed at the latest saucy kernel (and got it wrong, rc7 is not the latest, but anyway). I did this : wget -S http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-trusty /linux- headers-3.13.0-031300-generic_3.13.0-031300.201401192235_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-trusty/linux- image-3.13.0-031300-generic_3.13.0-031300.201401192235_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-trusty/linux- headers-3.13.0-031300_3.13.0-031300.201401192235_all.deb sudo dpkg --install linux- headers-3.13.0-031300_3.13.0-031300.201401192235_all.deb linux- headers-3.13.0-031300-generic_3.13.0-031300.201401192235_amd64.deb linux-image-3.13.0-031300-generic_3.13.0-031300.201401192235_amd64.deb reboot login Apport (or whoopsie ?) told me bbswitch failed, and indeed bumblebee was not active, with usual results (machine heats and makes a loud fan noise). tail -f /var/log/kern.log I plugged device, wait for a few seconds, see behavior, unplug the device.
