Hello everybody, I've tried to get the Edirol UA-4FX to work in advanced mode. There is a patch on http://alsa.opensrc.org/index.php/Edirol_UA-4FX . However, this does work for audio only, although the midi part is recognized as well: cat /proc/asound/devices 0: [ 0] : control 1: : sequencer 16: [ 0- 0]: digital audio playback 17: [ 0- 1]: digital audio playback 24: [ 0- 0]: digital audio capture 25: [ 0- 1]: digital audio capture 33: : timer 64: [ 2] : control 72: [ 2- 0]: raw midi 80: [ 2- 0]: digital audio playback 88: [ 2- 0]: digital audio capture and even a cat /dev/midi2 results in data when I play the connected midi device. But when I try to send midi data or receive midi data with aseqdump, the task falls in uninterruptible sleep and no data is sent according to /proc/asound/UA4FX/midi0. It seems as if the control data locks the device driver. The patch is simply copied from the code for the UA-25, this may be the problem. But I've got no idea how I could get it right. Any ideas? cat /proc/bus/usb/devices T: Bus=03 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=12 MxCh= 0 D: Ver= 1.10 Cls=ff(vend.)

MxPS= 32 Ivl=1ms I noticed that the "Prot" entries differ from the ones of the UA-25 shown here: http://alsa.opensrc.org/index.php/Edirol_UA-25#Device_information Don't know whether this has anything to do with it.
