"Found HC with no IRQ" empty /proc/bus/usb
Hey,
On my debian Dual 550MHz Pentium III machine, I am unable to get usb working. I didn't notice anything obvious in the bios that would disable USB. Any suggestions would be greatly appreciated.
I have tried several kernels, most recently 2.6.10 and 2.6.11.5. I have also tried booting with variations of
append="noapic acpi=off pci=biosirq"
Upon loading uhci_hcd module I see the following
$ dmesg <snip> usbcore: registered new driver usbfs usbcore: registered new driver hub usbcore: registered new driver hiddev usbcore: registered new driver usbhid drivers/usb/input/hid-core.c: v2.0:USB HID core driver USB Universal Host Controller Interface driver v2.2 PCI: Enabling device 0000:00:07.2 (0000 -> 0001) PCI: No IRQ known for interrupt pin C of device 0000:00:07.2.

is the age of the Bios is less then 2001 ? probably is , if so, you should append "acpi=force" to enable ACPI.
On some Bios configurations, you also have to enable ACPI and disable APM ( on Bios configuration )
