Now I see that you're using an older kernel -- the problem apparently

Hi,
this is what happens for
[rocketmouse@archlinux ~]$ pacman -Si linux | grep Ver; uname -rm
Version : 3.19.3-3
3.19.3-3-ARCH x86_64
[1]
and
[rocketmouse@archlinux ~]$ uname -rm
3.18.9-rt5-2-rt x86_64
[2]
So there seemingly is a serious issue on my machine too, but it's not
related to snd_seq_midi, since it's not needed, as you can see by [2]
before the USB devices are connected.
Regards,
Ralf

Indeed, with and without USB devices connected aconnect -i doesn't see
my MIDI devices, neither the PCI/PCIe, nor the USB devices.
Disconnected USB devices:
