If i remove ehci-hcd.ko from Linux-2..15-rc5 and then boot,
the USB keyboard and mouse work fine. I wiggle the mouse
and get interrupts in IRQ209:
r3000:~ # cat /proc/interrupts
CPU0
0: 34121 IO-APIC-edge timer
1: 12 IO-APIC-edge i8042
4: 1255 IO-APIC-edge serial
8: 0 IO-APIC-edge rtc
9: 147 IO-APIC-level acpi
12: 119 IO-APIC-edge i8042
14: 11386 IO-APIC-edge ide0
15: 969 IO-APIC-edge ide1
177: 4 IO-APIC-level yenta, ohci1394
185: 515 IO-APIC-level yenta, eth0
201: 403 IO-APIC-level NVidia nForce3
209: 4012 IO-APIC-level ohci_hcd:usb1
217: 0 IO-APIC-level ohci_hcd:usb2
NMI: 106
LOC: 34064
ERR: 0
MIS: 0
#modprobe ehci-hcd
and the mouse and keyboard stop working,
but if I CTRL-ALT-BACKSPACE to restart X, they start working
and I still see the interrupts on IRQ209:
r3000:~ # cat /proc/interrupts
CPU0
0: 73922 IO-APIC-edge timer
1: 12 IO-APIC-edge i8042
4: 1255 IO-APIC-edge serial
8: 0 IO-APIC-edge rtc
9: 279 IO-APIC-level acpi
12: 119 IO-APIC-edge i8042
14: 11925 IO-APIC-edge ide0
15: 2391 IO-APIC-edge ide1
177: 4 IO-APIC-level yenta, ohci1394
185: 1452 IO-APIC-level yenta, eth0
201: 403 IO-APIC-level NVidia nForce3
209: 6618 IO-APIC-level ohci_hcd:usb1, ehci_hcd:usb3
217: 0 IO-APIC-level ohci_hcd:usb2
NMI: 110
LOC: 73867
ERR: 0
MIS: 0
#rmmod ohci-hcd
and the mouse and keyboard keep working:
r3000:~ # cat /proc/interrupts
CPU0
0: 184941 IO-APIC-edge timer
1: 12 IO-APIC-edge i8042
4: 1255 IO-APIC-edge serial
8: 0 IO-APIC-edge rtc
9: 645 IO-APIC-level acpi
12: 119 IO-APIC-edge i8042
14: 14861 IO-APIC-edge ide0
15: 6333 IO-APIC-edge ide1
177: 4 IO-APIC-level yenta, ohci1394
185: 2657 IO-APIC-level yenta, eth0
201: 828 IO-APIC-level NVidia nForce3
209: 13484 IO-APIC-level ehci_hcd:usb3
NMI: 143
LOC: 184890
ERR: 0
MIS: 0
So it seems that either ehci-hcd or ohci-hcd will work, but
not so well together.
