This is very old, but I think this is worth mentioning how I got my Oxygen8
(keystation) working. This is a time-consuming issue.
I am on lucid lynx 10.04, and I too have the issue where udev is not
autoloading the firmware, but manually loading via fxload works fine.
adding -D $env{DEVNAME} did not work for me.
I was able to debug by stopping udev (sudo service udev stop), and running it
manually in non-daemon & debug mode: sudo udevd --debug. I was seeing that
$env{DEVNAME} was not getting populated at the time this was executed, but if I
ran:
udevadm info --query=property --path /devices/pci0000:00/0000:00:1d.3/usb5
I could see devname property was getting set: DEVNAME=/dev/bus/usb/005/001
Found this post which was helpful in determining that the udev rules for
midisport firmware loader was too restrictive?
https://bugs.launchpad.net/ubuntu/+source/udev/+bug/102631
I seemed to fix it by editing the line in
/etc/udev/rules.d/42-midisport-firmware.rules for the KeyStation to this:
ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device",
ENV{PRODUCT}=="763/1014/*", RUN+="/sbin/fxload -s
/usr/local/share/usb/maudio/MidiSportLoader.ihx -I
/usr/local/share/usb/maudio/MidiSportKS.ihx"
(note that I removed the DEVPATH filter and added the ENV{DEVTYPE} filter).
This did the trick for me.
