Hello all,
I've been trying to get an Actisys IR-210L infrared dongle running. It is plugged into a FIR 5-pin connector on my Via Epia 5000 motherboard. Extensive googling yielded no result so far.

Code Sample
dmesg|grep irda:
<6>IrDA: Registered device irda0

Afaik this indicates that the kernel found an irda-compatible chipset.
Code Sample
[home/dsl]#irattach irda0 -s
[home/dsl]#ifconfig
irda0     Link encap:UNSPEC  HWaddr 59-C3-98-8B-00-00-00-00-00-00-00
         UP RUNNING NOARP  MTU:2048  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:1806 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:8
         RX bytes:0 (0.0 B)  TX bytes:57534 (56.1 KiB)

This would indicate that I've got an infrared interface looking to discover near devices - Vivat!

However, syslog looks distinctly dodgier:
Code Sample
[home/dsl]#cat /var/log/messages
Jan  7 22:22:04 weksarahdio user.info irattach: executing: '/sbin/modprobe irda0'
Jan  7 22:22:04 weksarahdio user.info irattach: + modprobe: Can't locate module irda0
Jan  7 22:22:04 weksarahdio user.info irattach: Trying to load module irda0 exited with status 255
Jan  7 22:22:04 weksarahdio user.info irattach: executing: 'echo weksarahdio > /proc/sys/net/irda/devname'
Jan  7 22:22:04 weksarahdio user.info irattach: executing: 'echo 1 > /proc/sys/net/irda/discovery'
Jan  7 22:22:04 weksarahdio user.info irattach: Starting device irda0

Then run irdadump to see that the thing ignores my beloved Siemens C75 placed close to the dongle.
Code Sample
21:37:05.600929 xid:cmd 8b98c359 > ffffffff S=6 s=0 (14)
21:37:05.690935 xid:cmd 8b98c359 > ffffffff S=6 s=1 (14)
21:37:05.780963 xid:cmd 8b98c359 > ffffffff S=6 s=2 (14)
21:37:05.870933 xid:cmd 8b98c359 > ffffffff S=6 s=3 (14)
21:37:05.960933 xid:cmd 8b98c359 > ffffffff S=6 s=4 (14)
21:37:06.050934 xid:cmd 8b98c359 > ffffffff S=6 s=5 (14)
21:37:06.140936 xid:cmd 8b98c359 > ffffffff S=6 s=* weksarahdio hint=0400 [ Computer ] (27)

Trying variations with -d actisys et al. yield similar results. This is driving me bonkers and any hints would be greatly appreciated !!
Cheers, Bob

Are you trying to use the device in SIR emulation mode or have you loaded a module to try to use it in FIR mode?

The reason I ask is that you might need to disable a conflicting serial port to use the the device in FIR mode. In SIR mode you might need to tell the system which /dev to use.

For info, on my laptop the SMCS IrCC device will work in SIR mode but hangs dsl when I attempt to use it in FIR mode. Using dsln, both SIR and FIR work.

Irda modules aren't in the base - they can be gotten from net-modules.tar.gz from current/extra_modules from your favorite mirror..

- depends which one, they are in 3.x but not in 4.x

You can also get the irda modules for 4.x from the mydsl modules section - irda_modules-2.4.31.dsl
