Hi,
I am unable to get the Midiator MS-124W midi interface to work with alsa.
I have followed the instructions that come with the kernel, but all i get
is an error. I have tried to provide some of the information about what I am
running. Any help that can be provided I would appreciate. I haven't been able
to get this midi interface going with any of the 2.6.x kernels but it worked
fine with the 2.4.x series.
I am not sure what my next move should be.
Any help will be very much appreciated!
-Thanks in advance
Darwin
This is the error that I get following the instructions that come with the Kernel:
# setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
# modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=2
FATAL: Error inserting snd_serial_u16550
(/lib/modules/2.6.2-rc2/kernel/sound/drivers/snd-serial-u16550.ko): No such device
I am running the 2.6.2 kernel with devfs:
# uname -a
Linux schwaalap 2.6.2-rc2 #2 Tue Jan 27 15:48:43 EST 2004\
i686 mobile AMD Athlon(tm) 4 2400+ AuthenticAMD GNU/Linux
alsa-lib-1.0.2
alsa-utils-1.0.2
these are the midi devices that I see in /dev :
ls -l /dev/*midi*
lr-xr-xr-x 1 root root 14 Feb 3 15:31 /dev/admmidi1 -> sound/admmidi1
lr-xr-xr-x 1 root root 12 Feb 3 15:31 /dev/amidi1 -> sound/amidi1
lr-xr-xr-x 1 root root 13 Feb 3 15:31 /dev/dmmidi1 -> sound/dmmidi1
lr-xr-xr-x 1 root root 11 Feb 3 15:31 /dev/midi1 -> sound/midi1
This is the relevant excerpt from
/usr/src/linux-2.6.2-rc2/Documentation/sound/alsa/serial-u16550.txt :
In MS-124W S/A mode, one raw MIDI substream is supported (midiCnD0);
the outs module parameter is automatically set to 1. The driver sends
the same data to all four MIDI Out connectors at full MIDI speed.
Usage example for S/A mode:
/sbin/setserial /dev/ttyS0 none
/sbin/modprobe snd-serial-u16550 port=0x3f8 irq=4 adaptor=2
I don't see any /dev/midiCnD0 I am using the alsa drivers in the kernel. Why isn't
this working?
In the documentation it says that devfs is supposed to take care of the device setup.
here are excerpts from dmesg:
Serial: 8250/16550 driver $Revision: 1.90 $ 8 ports, IRQ sharing disabled
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS1 at I/O 0x8828 (irq = 3) is a 8250
ttyS2 at I/O 0x8840 (irq = 3) is a 8250
ttyS3 at I/O 0x8850 (irq = 3) is a 8250
ttyS4 at I/O 0x8860 (irq = 3) is a 8250
ttyS5 at I/O 0x8870 (irq = 3) is a 8250
