[irda-users] Toshiba Satellite Pro 2100 with SMC on 82801 CAM - 248C

[Gwyn <gw...@de...>]

Hi -

I'm trying to get infrared (fast or slow) working on a Toshiba Satellite
Pro TE2100. It works in XP, which says that it's an "SMC IrCC - Fast
Infrared Port" on "Intel 82801CAN LPC Interface Controller - 248C" using
DMA 1, IRQ 7, IO 0130-0137 and 02F8-02FF.

Under Linux (2.6.0) it's "00:1f.0 ISA bridge: Intel Corp. 82801CAM ISA
Bridge (LPC) (rev 02)". 

There's no access to anything irda-related in the BIOS. 

I can modprobe irda, ircomm, ircomm-tty okay. Donauboe modprobes okay
with no output to syslog, but /proc/net/irda/discovery doesn't show any
devices when the phone is in range. /proc/sys/net/irda/discovery is 1.  

'ip link set irda0 up' says  'SIOCGIFFLAGS: No such device'

I have /dev/ircomm* (for *=0..31), but kppp says "Modem is busy" when
pointed to /dev/ircomm0.

Irdadump says nothing.

Modprobe smsc-ircc2 gives
'Apr 22 19:06:24 localhost kernel: found SMC SuperIO Chip (devid=0x5a
rev=00 base=0x002e): LPC47N227
Apr 22 19:06:24 localhost kernel: smsc_superio_flat(): IrDA not enabled
Apr 22 19:06:24 localhost kernel: smsc_superio_flat(): fir: 0x2f8, sir:

Apr 22 19:06:24 localhost kernel: smsc_ircc_present(), addr 0x02f8 - no
device found!'

in syslog.

Then I did './toshsat1800-irdasetup --irq=7 --dma=1 --firbase=0x2F8
--sirbase=0x2e8 --vendor=0x8086 --device=0x248C --cfgbase=0x0130'

Syslog said

But 'modprobe smsc-ircc2' gave the same output as before, and still
wouldn't install.

Can anyone help?

Thanks,

Gwyn.
