Hi,


Could you post the result of "lspnp -v" with pnpacpi and pnpbios ?


Thanks

Here's the output of lspnp -v with pnpbios. When I run it with pnpacpi, 
it says that /proc/bus/pnp doesn't exist and dies. These 4 lines appear 
about halfway through dmesg output (in this order, no text omitted 
between first and last line):

ACPI: bus type pnp registered
pnp: PnP ACPI: found 11 devices
ACPI: ACPI bus type pnp unregistered
PnPBIOS: Disabled by ACPI PNP

What should I do to get lspnp work with pnpacpi?

Regards,
Martin Doucha

Use a newer version of lspnp.

An alternative is to do a for i in /sys/bus/pnp/devices/*; do echo $i; 
cat $i/*; done

Looking for any version of lspnp seems harder than finding a needle in 
barn full of hay... Here're the contents of /sys/bus/pnp/devices, the 
parallel port seems to be detected as device 00:08 (line 81) but there's 
no mention of it in dmesg, /dev or /proc/sys/dev/parport

Uhh, no, it's device 00:0a on line 1 and kernel says it's disabled?! 
It's enabled in BIOS and dmesg doesn't mention it so why is it disabled?
