Couldn't find Winbond superI/O chip.
In the BIOS, the chip is configured at /dev/ttyS3 and irq 0x2e8. I can see it in dmesg: $ dmesg | grep ttyS [ 1.318041] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 1.318339] serial8250: ttyS3 at I/O 0x2e8 (irq = 3) is a 16550A [ 1.318770] 00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A In the device manager, it's listed as PNP device SMCf010 with sysfs path /sys/devices/pnp0/00:0d Finally, $ lsmod | grep ir irtty_sir 9600 0 sir_dev 17156 1 irtty_sir ircomm_tty 39560 0 ircomm 23684 1 ircomm_tty irda 201276 4 irtty_sir,sir_dev,ircomm_tty,ircomm crc_ccitt 3072 1 irda and $ sudo modprobe irda0 Password: FATAL: Error inserting nsc_ircc (/lib/modules/2.6.20-16-generic/kernel/drivers/net/irda/nsc-ircc.ko): No such device -- irda-setup (irda-utils) does not detect irda chipset on Dell Latidude D820 https://bugs.launchpad.net/bugs/176386 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
