OK, this is telling you that ttyS2 is not the correct COM port for your irda device. However, looking at your dmesg there's only two serial ports reported, so ttS2 is not defined: =========================================== serio: i8042 AUX port at 0x60,0x64 irq 12 serio: i8042 KBD port at 0x60,0x64 irq 1 =========================================== You need to enable some virtual (COM) ports. In your kernel configuration you will need to set additional serial ports. Go to: Device drivers --> Character devices --> Serial Drivers --> and either enter a number higher than just 4 under: (4) Maximum number of 8250/16550 serial ports (4) Number of 8250/16550 serial ports to register at runtime or better, on the latest stable kernel select: [*] Extended 8250/16550 serial driver options [*] Support more than 4 legacy serial ports [*] Support for sharing serial interrupts If when you reboot you keep getting the same error then you need to try different ttySx number, where x is 0,1,2,3,4, . . . Note that some numbers could cause IRQ conflicts and could crash your machine. In that case reboot and try again. > biit ~ # /sbin/modprobe smsc_ircc2 > FATAL: Error inserting smsc_ircc2 > (/lib/modules/2.6.15-gentoo-r1/kernel/drivers/net/irda/smsc-ircc2.ko): > No such device Unless the COM port has been set correctly for your irda any module selection will fail. > ------------------------------------------ > > When i execute the next sentence: > ------------------------------------------- > biit ~ # irattach irda0 -s > ------------------------------------------- > > This is what appear into syslog: > ------------------------------------------- > Sep 2 21:53:04 localhost irattach: executing: '/sbin/modprobe irda0' > Sep 2 21:53:04 localhost irattach: + FATAL: Module irda0 not found. > Sep 2 21:53:04 localhost irattach: Trying to load module irda0 exited > with status 1 > Sep 2 21:53:04 localhost irattach: executing: 'echo biit > > /proc/sys/net/irda/devname' > Sep 2 21:53:04 localhost irattach: executing: 'echo 1 > > /proc/sys/net/irda/discovery' > Sep 2 21:53:04 localhost irattach: Starting device irda0 > Sep 2 21:53:04 localhost irattach: ioctl(SIOCGIFFLAGS): No such device > Sep 2 21:53:04 localhost irattach: Stopping device irda0 > Sep 2 21:53:04 localhost irattach: ioctl(SIOCGIFFLAGS): No such device > Sep 2 21:53:04 localhost irattach: exiting ... > ---------------------------------------------- Ditto. > > Does your dmesg show anything? e.g. mine shows: > > =================================================== > > found SMC SuperIO Chip (devid=0x0e rev=01 base=0x002e): LPC47N252 > > =================================================== > > This is my dmesg: > http://paste.lisp.org/display/25171 OK, it would be really strange if an irda chip of your type was detected just out of thin air without COM ports set in the kernel.
