I've managed to collect two PCAPNG files, one captured using virtualized Windows 7 and the second directly under Ubuntu 16.04LTS fully upgraded up to date.
In both sessions, after initialization I pressed "a" key, then special key "G6". The "a" key makes four packets to be recorded. The "G6" special key generates six packets under Windows and only four packets under Linux (the first two packets that can be seen in the Windows dump never occur in Linux). After hitting "G6", the Windows session is fully responsive. But in the Linux session, the device stops responding until: a) is unplugged, then replugged. b) the USB is connected to the Windows Virtual Machine (VirtualBox), which resets the device and makes it responsive again. In the Windows dump, the last 10 packets correspond to the "a" keypress (4 packets) then "G6" keypress (6 packets). In the Linux dump, the last 8 packets correspond to the "a" keypress (4 packets), then "G6" keypress (only 4 packets). ** Attachment added: "PCAPNG dumps of keypress "a" then "G6" (Windows and Linux)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511511/+attachment/4721381/+files/pcapng_dumps.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1511511 Title: USB keyboard stops working after pressing extended key To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511511/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
