I was using M-Audio Oxygen Keyboard in udev v237, Ubuntu 18.04 LTS. According to lots of the changes in udev since v136, the rules configuration of this package (from sourceforge) is out of date.
The newest fix I can find is in following repo: https://github.com/oeai/m-audio-usb-midi-fw/ I have to change all the rules 'SUBSYSTEM=="usb_device"' to 'SUBSYSTEM=="usb"' before installing it, However, it finally works for my keyboard. Hope this helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/517750 Title: udev rules under /etc have incorrect path to firmware files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/midisport-firmware/+bug/517750/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
