[Bug 1720842] Re: USB Keyboard "Masione VMJ-02" ID 1c4f:0056 SiGma Micro: Ctrl / Super / Alt incorrectly recognized as L-Shift
>From Peter's description of the problem I guessed that it was wireshark setting promiscuous state on the virtual usbmon interface that caused the keyboard to go back to working state, which I knew should also be possible via tcpdump -i usbmon3 where usbmon3 is the interface that corresponds to the usb device in question. This works as a short term hack. sudo modprobe usbmon && sudo tcpdump -i usbmon3 Then you will be able to use the keyboard to ctrl-c out of it. Once the state has been set it appears to be permanent and persistent until next reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720842 Title: USB Keyboard "Masione VMJ-02" ID 1c4f:0056 SiGma Micro: Ctrl / Super / Alt incorrectly recognized as L-Shift To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I was just sitting down to figure out how to write a device driver, and when I loaded the usbmon module and fired up wireshark the keyboard started behaving. The first few keys were captured with the "modified" keycodes that the usbhid driver doesn't recognize properly, then it seems to have switched into "normal" mode and behaved like a regular usb keyboard. I tried it on two computers with the same result, i.e. sudo modprobe usbmon, sudo wireshark "fixes" the problem for some strange reason. Now if only I could figure out how to trigger the mode switch in a less annoying way that would be great. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720842 Title: USB Keyboard "Masione VMJ-02" ID 1c4f:0056 SiGma Micro: Ctrl / Super / Alt incorrectly recognized as L-Shift To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hmm, OK, I'll have a look, thanks - might be a fun weekend project. Though it sounds like a new keyboard is a better option.
